Stone Care and Cleaning


The Importance of Cleaning

The daily removal of ordinary dirt and soil is an important phase in the maintenance of Granite. Sweeping compounds containing oil must never be used on marble because they will eventually discolor the surface. If floor is heavily trafficked it should be cleaned daily and rinsed with clean water until all traces of dirt solution are removed. Marble should then be allowed to dry.

Granite Maintenance Procedures

The care and cleaning of Granite products is quite simple, if the proper procedures are followed, products will maintain their natural beauty and durability for a lifetime. To ensure the best service from Granite products, clean the product thoroughly after installation, and follow up a regular maintenance program.

Immediately after completing installation, wash the floor clean of loose debris, dirt and foreign material. Use clean, soft cloths, sponges or mops and fresh warm water. Allow to dry. A second rinse application may be required to remove any additional film. Apply a thin, even coat of sealer and allow to dry for 3-5 minutes, removing excess sealer before it dries. If too much of material is applied, it may be removed by re-applying sealer to re-activate residue, buffing it off before it dries. Finished area can be used for normal foot traffic in 3-5 hours, but must be kept dry and free of staining agents for 72 hours.

It is strongly recommended that the above-mentioned procedures be completed immediately after installation and repeated in a regular maintenance program.

Suggestions for the Maintenance of Granite

The physical characteristics of Granite govern the methods of maintenance and the products chosen to treat and maintain it properly. Marble is a natural product of crystallized rock composed of calcium carbonate. Generally, Granite used in the interior of buildings for decorative purposes has either a polished finish (glossy surface reflecting light) or a honed one (dull and smooth surface giving relatively little reflection of light). Each of these types of marble finishes should be treated in the same manner.

Why Does Granite Need Maintenance?

Because marble is naturally porous, it is necessary to use a penetrating (not surface) sealer. Such penetrating products fill the pits and voids and actually become an integral part of the floor itself. The primary purpose of sealing is to provide protection to the Granite itself. Ordinary dirt and soil are sealed out of the floor as if all pits and voids have been filled and sealed. They are held on the surface where they can easily be removed. Marble floors properly sealed and finished are easy to clean and maintain. Granite floor should not be sealed until the surface is thoroughly cleaned and dried.

Why Granite Should Be Kept Clean?

The secret to beautiful marble is merely keeping it clean agents original treatment with sealer. Complicated cleaning agents and maintenance procedures will never be needed if the Granite surfaces are regularly cleaned. If marble deteriorates it is simply because it’s cleaning has been neglected or harsh damaging cleaners have been used. When Granite is neglected dirt and grease are allowed to accumulate, therefore the surface can be damaged almost beyond repair and cracks can be caused by general deterioration. Improper cleaning materials such as those containing alkali, acid metallic salts or other strong ingredients actually attack the Granite itself and increase and enlarge dirt catching pores. Soap or abrasive type cleaners should never be used on Granite surfaces. This type of cleaner reacts with the calcium carbonate /the marble itself to build a soapy scum which destroys the beauty of the Granite and forms a greasy or slippery film that will catch or hold dirt.

The use of an abrasive cleaner will result in unsightly scratches on the surface. Abrasive cleaners are almost impossible to remove by rinsing and normal foot traffic will grind the left over abrasive particles into the surface, thus running the floor. The ideal cleaner should be first of all, effective in removing soil. Secondly, it should not develop any damaging discoloration or surface film. It should be rinsed free even in hard water.

Natural stone has always been a symbol of strength and durability


There are several main types of road surface: asphalt, solid concrete, concrete blocks and slabs, paving stones and, of course, paving slabs.

Since time immemorial, our ancestors paved road boulder - a naturally occurring stone, a form which gives nature. The main drawback of this method was that the boulders had a completely different form, it was difficult to put them close to each other, and because the process took a long time, and the road surface turned out to short-lived.

Natural stone has always been a symbol of strength and durability. And it is quite natural. Only after five centuries of exploitation of granite paving blocks it is possible to detect the first signs of aging. Not for nothing is called the eternal granite stone. However, with all its strength, granite is susceptible of mechanical and thermal treatment, a well-pricked, perfectly polished.

In European urban development of natural granite cobbles used everywhere, especially for the paving of the main streets, parks and squares.

Granite pavers are not only strong and durable material. Setts of natural stone has the highest aesthetic qualities, and therefore a sign of good taste, as well as wealth and prosperity.

Cobble Stone Matting - Installation Hints



Installation Hints
Please note: Any colour and / or texture variations are a common occurrence and proof of a natural stone product.
> Ensure that all surfaces to be faced are clean and free of all loose material and dust.
> apply mats to a previously painted, sealed or coated surface. Specialist advice is to be sought for treatment of painted, sealed or coated surfaces prior to fixing matting.
> When placing the adhesive spread approximately 1/2 inch thick same size as mat.
It is very important to ensure that the adhesive penetrates the nylon mesh and covers the
entire back of the stone pieces. Press the stone mats into position and use a soft mallet to ensure spread of adhesive.
> Ensure that the adhesive being used is suitable for use with stone products and for the
particular application. I.E. Interior, Exterior, Water Feature etc.
> When using the matting for a water feature it is to ensure that the adhesive
used is suitable for immersion in water.

> Use a dry grout mix (3:1) and brush into mortar joints. Then use a light mist to set
the grout. This will help when cleaning the cobbles due to corrugations in the stone.
> Prior to grouting with a colour oxide, it is recommended that the natural stone is treated with a grout-release/sealant to prevent any colour oxides in the grout leeching into the stone pieces.
> It is recommended that the natural stone is sealed with a suitable sealant to protect the stone surface.
> Sealant should be re-applied as per recommendations of the manufacturer's guidelines.

COBBLES & SETTS


The original “Cobble” (Cob) was a rounded river-washed stone, which later gave way to the larger and more regular rectangular shaped ‘Hovis-style’ “‘Sett”’. The name (Cobble or Sett) is different depending on your location or perception, but the product is basically the same. They might come as small as 100mm square cubes or can be as large as 250mm x 200mm x 250mm, and they can be sandstone or granite… but one thing is certain, they are on their way back into fashion ! and there is no better ‘entrance statement’ than a beautifully cobbled driveway.

Whether for cobbled driveways and paths or larger civic areas; more and more architects and developers are being asked to use good old-fashioned street cobbles, instead of the other less robust and less visually pleasing methods of hard-pave construction.

It would be difficult, if not impossible to find another reclaimed stone product that looks as visually stunning and spectacular as a cobble driveway, patio or recreational area.
Cobbles and Setts are widely used to transform otherwise bland open expanses into visually pleasing works of art, and as well as being aesthetically superb they are incredibly robust for every form of foot or vehicle traffic; and when laid properly can be enjoyed by many generations to come.

Common from the 15 th Century onwards, the use of cobbles goes back to Roman times, and they are still evident in most of the historic towns and cities throughout the British Isles today.

The Beauty of Stone, Porphyry, Granite, Cobble, and Slate Paving Driveways


The Beauty of Stone, Porphyry, Granite, Cobble, and Slate Paving Driveways

Creating driveways out of stone, porphyry, granite, cobble, or slate is an important decision that must be carefully analyzed. These driveways are very beautiful, but they require an extensive amount of installation time and effort.


Using these types of materials correctly for a driveway requires precision, practice, and a good eye for details. Therefore, if you are personally installing a stone paving driveway, it is important that you understand exactly how to complete the job perfectly. If you are hiring a professional do the installing, ask to see examples of the work that the contractors has done before and get references to ensure their expertise in installing stone, flagstone, cobble, and slate driveways.

However, the effort certainly pays off, as stone, porphyry, granite, cobble, and slate paving driveways are visually attractive and can add great aesthetic value to your property.

Precision is critical

The first thing that you have to remember when you are installing a porphyry, granite, stone, cobble, or slate paving driveway is that you work with precision. Because of the texture of the materials, this is often hard to do.

You want to map out your entire driveway, check that you have measured the stones and that they fit the driveway precisely. The hardest part of constructing your own cobble, stone, flagstone, or slate paving driveway is that they always have a specific pattern that brings it aesthetic value. However, they must be carefully organized and placed in an exact manner to ensure that the driveway works well and maintains its integrity in any weather condition.

Practice ensures success

Not only do the materials need to be in exact positions, but you also have to be sure that installation is specifically for the slate, porphyry, granite, cobble, or stone paving driveway that you have chosen to build. This means that you must understand the workings of each material, as well as how to secure them in the ground. You cannot learn by installing on your own , as this will result in a failed stone, flagstone, cobble, or slate paving driveway – if you have any doubts at all then ensure you get a professional in to look after the installation.

Instead, it is important to practice your techniques and design. If you have a back area or side yard where you can practice, that is an ideal place to start. If you do not have an extra practice space, then carefully measure and sketch out the pattern of your driveway. You may want to take the time to layout the stone, flagstone, cobble, or slate materials to practice your understanding of the dimensions and pattern of your design.

Details will complete the beauty

The best flagstone, stone, cobble, and slate paving driveways have detailed and beautiful patterns. The more intricate the pattern, the more beautiful the driveway will be. This means that you have to focus on the details. Your research, planning, and training will ensure that you can fully execute the gorgeous details of your chosen material, whether it is stone, porphyry, granite, cobble, or a slate driveway.

Porphyry Stone Description



Porphyry is a volcanic rock originating from the ignimbrites and the consequence of an intense volcanic activity began about 260 million years ago and continued for many millions of years, with an alternation of eruptive phases and stasis.

Peculiarities of the porphyry is to present a natural surface of the quarry. It 'a kind of stone that can be used for different applications, ensuring consistent good results, even in complex projects from the architectural point of view, thanks to the wide range of colors combined with specific physical and mechanical : high tensile strength, compression, excellent chemical resistance, high sliding and rolling friction. The porphyry has always been used since antiquity for the construction and decoration of the streets and even today, for its natural roughness continues to be the preferred material for all types of flooring, including those subjected to constant and heavy traffic heavy. The red color cast, with punctuation pink, white and gray - both in the more commercial varieties of Trentino - the base color gray at which combine different shades of color from purple ocher. In addition to marketing the company also provides an important operational advice in the design and installation, assisting the client in all phases of pre and post sale.

Porphyry stone has been used for paving since ancient times



Porphyry stone has been used for paving since ancient times. Many of these roads, plazas and walkways are still in use today – testament to its durability. It is distinguished by the richness of its coloration– porphyry means purple in Greek – and its characteristic purplish- red or greenish- brown color have made it a popular choice over centuries as a building material.

Porphyry – extrusive ignimbrite – is formed under such intense heat and pressure that it is denser than most granite. Because of its density, Porphyry is non-absorbent. That feature makes it impervious to cracking – water can't penetrate to freeze and expand as with other stones. Porphyry has an even yet textured surface. Due to the hardness of the minerals it contains, Porphyry pavers do not become smooth from wear or slippery when wet.

Variation in color is a significant characteristic of Porphyry stone. Predominant colors are grey and red, but can range into reddish-brown, violet-grey, even pink, with rare intrusions of brown, green or gold. Occasionally, the stone will reveal the delicate tracery of fossils, contributing to its complexity and uniqueness.

In general, grey Porphyry is more uniform, and reads as more solidly grey once installed. The red stone is rich with earthy warm hues.

Granite is an igneous rock rich in silica



Granite (Italian granito, from lat. Granum - grain), is an igneous rock rich in silica. One of the most common rocks in the Earth's crust .Granite consists of potassium feldspar (orthoclase, Microcline), acid plagioclase (Albita, oligoklaza), quartz, and mica (biotite or muscovite), amphiboles and rare pyroxene.

The structure of granite usually crystalline, often porphyritic and gneissic banded. According to its physical and mechanical properties granite is a wonderful construction material. Ruggedness and density of granite, its broad texture capabilities (the ability to become mirror polished, with which the rainbow play of impregnated mica is visible; sculptural expressiveness of mat rough stone absorbing light) makes granite one of the basic material of monumental sculpture.

Granite is also used to make obelisks, columns and as a lining of different surfaces.

Setts of natural stone - is the most strong and durable material. Paving of sidewalk pavement is a necessary element of the city and park beautification. With pavers you can quickly create an unusual and very beautiful cover. On the surface, there are no puddles. The porosity of the stone allows moisture to evaporate freely penetrate and prevents the formation of a water-coated mirrors.

Cobbles available polnopilennoy (possible heat treatment of the front surface), chopped, sawn, chipped form.

Installation Instructions


Installation Instructions

1. Layout

First, measure the area you intend to pave. Determine square footage by multiplying (length x width = square footage), add 5% for breakage and cutting. Measure the lineal feet of open edges, those not up against a permanent structure such as a house, etc. This will indicate the lineal footage of Pave Edge, the plastic edge restraint, required.

Using the 3-4-5-triangle method to determine a line that is perpendicular to the house, measure parallel lines from the perpendicular line to establish a boundary. Stakes can be placed every 4 to 6 feet to outline your boundary. These stakes should be 8" outside of the planned edge of the pavers. You can check to make sure an area is square by making sure both sets of cross corners measure the exact same distance. It is important to maintain true 90-degree corners if you do not wish to make cuts. If you are planning a project with a radius or with shapes that are not rectangular, then paver cuts will have to be made.


2. Excavation

NOTE: Before any digging call your local utility companies to locate any underground lines.

Using a flat shovel cut evenly to remove sod/dirt to a depth that allows for a 2-3/8" paver, 3/4" layer of sand, and 3-6 inches of compacted 3/4" minus. On vehicular applications, more 3/4" minus may be needed. You may need to use a wheelbarrow to move excavated soil to another location.


3. Base Preparation

This step will be the most critical part of the installation. The more time and effort you put into the preparation of the base, the better the project will be and the longer it will last. The base material itself will consist of a crushed limestone rock called 3/4 minus. It contains rock from 3/4" in diameter all the way down to fine dust, and will provide excellent compaction. This is the time you will need to rent a plate compactor. First, run your compactor over the excavated soil. (Make sure no soil gets stuck to the bottom of the plate compactor). Each pass should overlap the previous one by about 4". Now spread your base material out evenly in 2-3" thick layers. If the base material is dry and dusty use a garden hose to give the material a light spray as this makes the base material faster to compact and easier to rake. Begin around the outer perimeter. Overlap each pass about 4" working towards the center. You should make at least two complete passes for each layer. Use your hard-tooth rake to rake out any unevenness. (Try spreading material with rake turned upside down).

When finished with base it should be very smooth and flat. If you were to put a straight edge flat on the surface, there should be no more than a 1/4" gap anywhere along the straight edge and the base.

Slope and Grade are important to ensure proper runoff. Plan at least a 1/4" per foot drop, away from your home, but try not to exceed 1/2" per foot.


4. Pave Edge

You are now ready to anchor in place your plastic Pave Edge restraint pieces. First, it is necessary to snap some chalk lines. The first chalk line should be up against, and parallel to the house foundation, with a length equal to your patios width. This is done in order to check for any unevenness in the foundation wall. Then by using the X measurement method, find the outside corners of the patio. This is accomplished by achieving the same distance from corner to corner and corner to corner in an X pattern. Mark these corners. Now snap your chalk lines to form your perimeter. Once again, check for square. Now install your pave edge along the three outside perimeter lines using the steel landscape spikes at two-foot intervals. Drive the spikes into this edging so that the chalk line remains visible. It may be necessary to cut and piece together the Pave Edge Pieces as they are provided in 10-foot lengths. Connectors are included with the Pave Edge to connect sections that are longer than ten feet.


5. Sand Setting Bed

Note: It is important to keep your sand dry. Always keep your sand covered in case of rain.

Do not attempt to level any area or surface irregularities with the sand. This will result in an uneven surface and unwanted settling.

Lay your screed guides (3/4" electrical conduit pipe or other suitable 3/4" guide) directly on the compacted base material in the center of the 10 foot section, running perpendicular from the house. Spread the sand starting from the center, nearest the house, directly on top of the screed rail, so that it stays in place, working away from the house and towards the perimeter. You will use your 6-8 ft. 2x4 to loosely spread the sand and to strike off any excess. Start against the house working towards you, pulling the screed board with a side to side motion over the screed rails. At the beginning, screed only an area which you can reach in order to lay a sufficient area of pavers so that you can have enough space to get on the pavers and work out from. Do not walk on your screeded sand. Then continue with screeding the remainder of the setting bed. Do not worry about voids that screed guides have left after you have removed them. You will lightly fill them with sand and trowel them smooth as you are laying the pavers.

6. Laying the Pavers

Starting from either corner near the house, lay your first paver moving with additional pavers towards the opposite side (moving left to right then right to left and so on, one row of pavers at a time. Work on top of the pavers, not in the sand. Set pavers lightly on the sand, never press or hammer them into the sand bed. It is important to maintain straight lines in the pavers. To check for straight lines run a string from one end of the surface to the other over the laying edge of the pavers. Do this about every 3 feet or so. If there are some pavers lagging behind go back about three rows and using a small pry bar, wedge between the pavers and pry the pavers forward until they are in line again. Do not worry too much about the gaps at this point, they will even out during tamping later. Only set the pavers hand tight, and do not use a hammer to adjust the pavers or set them.

If you do not finish laying the pavers completely before the end of the day, cover the project that night if rain is expected.

If after laying the pavers you should need to adjust the Pave Edge slightly do so by pulling out the spikes with your pry bar, and then reinstalling.


7. The Final Steps

In this step, the pavers should settle in about 1/8" lower during compaction (only if loose screeded sand was used).

Sweep off any debris or loose sand that may be on the pavers.
Using a vibratory compactor you should make at least two passes over the pavers, starting around the perimeter and working inward overlapping each pass 2 to 4 inches. Make the second pass at a 45-degree angle to your first pass. The first pass of the compactor will accomplish the following:
will level all the pavers
compact the sand bedding course
force the sand up into the joints
Make two more passes with plate compactor. Continue to sweep sand in joints with the sweep broom until the joints are full.
Sweep off all excess sand and backfill edges with topsoil and seed or sod. Be sure to water regularly.
If you desire the appearance to have a "wet look", a solvent based sealer can be roller applied to the application. Check your supplier for pricing and information on this sealer. The sealer will also help to contain the sand in the joints of the pavers.
Congratulations! You have now installed a maintenance free patio. Yours to enjoy for a long time to come.

Granite Application


Granite Stone

Granite is a very hard crystalline, igneous or metamorphic rock primarily composed of feldspar, quartz and lesser amounts of dark minerals. It is visibly crystalline in texture. The igneous granite rock is created deep within the earth from magma, cooled slowly under great pressure. Granite is considered the hardest building stone that has very dense grain which makes it impervious to stain. Granite Stone is available in a wide array of colors. varieties of different colors and textures such as black, grey, pink, red, blue etc.

Granite Application
Granite has been extensively used as a dimension stone and as flooring tiles in public and commercial buildings and monuments. In some areas granite is used for gravestones and memorials. Granite is a hard stone and requires skill to carve by hand.

Granite being the hardest stone and because of its architecturally beautiful it is highly used as building stone. It takes a highly polished finish and also available in variety of other finishes. Granite is available in a broad spectrum of colors ranging from nearly pure white to nearly pure black. The infusion of various minerals in varying compositions during the formation of granite provide differing patterns as well as colors. Naturally granite is available in colors like black, ruby red, pewter, mauve, rustic and gray. The typical applications of granite is that it is used as a building stone, architectural aggregate, track & trail pathways, decorative landscape stone, decorative rip rap stone and a source of economically valuable minerals.
