For light pedestrian use on the well-consolidated ground, excavate the depth of the pavers plus 50mm for the PREMIER-BASE-COURSE layer. For heavy garden equipment, vehicle traffic, hard standing or poor ground – a sub-base of 150 – 200mm depth is required. The sub-base should be well compacted and consist GAP-20 or similar (not larger than 25mm aggregate). Provide a fall of 10 – 15mm over every 1 metre to allow for water runoff. The falls should be away from the house or walls unless linear surface drainage channels are used. Building regulations require paving to be a minimum height below the floor level. Check your local building regulations for this information.
Any area of pavers must be surrounded by a firm edge restraint to stop the blocks and sand from moving sideways. New and existing walls, kerbs or the pavers themselves laid on a suitable concrete bed can all be used to serve this purpose. Any concrete used to fix edge restraints must be allowed time to cure and gain strength before any vibration is commenced.
After sub-base excavation and fill (if required) screed out PREMIER-BASECOURSE on top of the sub-base within the restrained area to an approximate depth of 65mm. Then compact with a plate compactor (obtained from your local hire shop). Then spread PREMIER-WASHED-SAND over at approx 5-10mm thickness and screed off to give a firmly compacted thickness of 50mm. One tonne of PREMIER-BASECOURSE covers approximately 8m2.
Individual pavers are then simply placed onto the sand bed and according to the pattern, laying progress from a corner or long edge and should proceed along one laying face until work is finalised. Pavers from several packs should be well mixed to enhance colour blending.
Cutting of pavers may be required to fill gaps between edge restraints. This may be done using a hammer and bolster chisel. If a lot of cutting is necessary, a mechanical block splitter or power cutter can be hired.
With a stiff broom, thoroughly brush a quality joint sand over the pavers to fill the joints before compacting. For smaller areas use a rubber mallet to compact. For larger areas use a plate compactor. Carpet may be required when compacting these pavers to help prevent them from cracking. Keep sweeping PREMIER-SWEEP-IN-GROUT in until all joints are topped up. Sweep in thoroughly to avoid staining during spraying. Then spray a fine mist of water over the area to help set the grout. ONLY USE SMALL AMOUNT OF WATER.
To maintain a just laid look, you can seal your pavers using either PREMIER-SEALER product of your choice. Talk to your local PREMIER distributor about PREMIER-SEALER for your pavers. Unsealed paving will weather naturally making colours appear less intense.
Step back – relax and enjoy the finished result.
