Step 4 Laying pavers
Lay whole pavers in the pattern of your choice – herringbone pattern is recommended for drives or other areas used by cars, whilst herringbone, running or basketweave bonds are all suitable for patios or paths. Drainage should be provided using standard gullies or channels.
Pavers should be laid by hand to your predetermined pattern, making sure that there is a minimum 2mm gap between them to allow for jointing sand – the gap can be increased to a maximum of 5mm if necessary. Cut any infill or edge pieces that are necessary using a block cutter designed specifically for clay pavers.
Step 5 Filling joints
For 200 x 100mm pavers, fill the joints by brushing fine sand (not bedding sand) into the joints. With cobbles and slimpave, fill the joints with bedding sand and apply a top dressing of fine sand after compaction.
Step 6 Compaction
When the pavers have been laid, the joints filled with fine sand and the surface sand removed, use a small plate compactor fitted with a rubber sole to vibrate the pavers into position on the sand bed. Repeat the sanding and compacting operation until joints are fully filled. Remember to monitor the joints and top them up with sand for some weeks after completion as initial settlement is inevitable.
Terca clay pavers are a low maintenance product. In the short term all they require is occasional sweeping and sand top-up from time to time. In the longer term, pressure washers can be used to remove dirt and return paving to ‘as new’ condition.
