Laying Method – Flexible
Laying Method – Flexible:
Note: This method of installation is only applicable for products smaller than 0.2m2 in plan area. It is not appropriate for products larger than 0.2m2 in plan area. It is always recommended to use a qualified experienced trades person for this installation method.
The Base course shall be levelled with in a tolerance of no more than 5mm from the base of the level in any direction. It shall be of an even thickness and adequate drainage precautions taken. It should be correctly compacted to suit the intended application. There should be no ponding on the surface of the base course as this may cause problems with the integrity of the paving application.
The Bedding sand must be of appropriate grading for the bedding application. The level of sand compaction must be taken into account when setting the levels for the bedding sand.
It must be spread evenly and appropriate precautions must be taken to ensure adequate drainage. It should not be assumed that the pavers will ”bridge” a poorly prepared base or bedding sand.
The pavers can be placed on the bedding sand and the grid lines adjusted using a screwdriver where necessary.
An edge beam may be necessary to put in place if the paving area doesn’t provide them i.e. a wall or kerb etc. The edge beams are generally made using a concrete mix to the relative Australian standards.
The thicknesses of the bedding sand should not exceed 35mm when compacted.
Compacting of the paver can be done using an appropriate compacting plate. It is recommended to cover the plate with a soft layer of material to avoid chipping the surface of the pavers (ie Carpet). Compacting of the pavers should be kept back 1m from the laying edge unless it has the appropriate edge beam or structural edge i.e. wall or kerb etc.
The joints in the pavers can be filled after compaction with appropriate jointing sand. It can be swept into the joints. It is not recommended to use a ridged style grout for this method of laying.
The area can be re-compacted after the joints have been swept with sand and more sand applied where necessary.
The sand should be dry and the joints should be filled as soon as possible after the initial compacting has taken place.
Regular checks should be done to ensure that the paving is performing as desired and any maintenance should be carried out to ensure the structural integrity of the paving.
