Laying paving:
There are several techniques for laying paving. To be in accordance with building regulations, however, paving must be laid on a concrete screed with lean mortar.
The ground must be cleared of topsoil, leveled, consolidated and drained if necessary before being compacted. If required, lay and compact crushed stone. Never lay paving on a recent or uncompacted backfill.
Pour a concrete screed 8 to 12cm thick on firm ground, using 300kg of cement per cu.m, with steel lacing reinforcement.

- The concrete screed must have a 1:00 to 1:50 slope to evacuate rainwater in the desired direction.
- Leave expension joints between the slabs, and alongside the pool and all buildings.
- Wait until the screed has fully hardened before laying the paving.
- Lay Weser paving on at least 3cm of lean mortar, using 250kg of OPC cement per cu.m of 0/5mm dry sand (do not use other types of cement or products containing lime). The mortar must be leveled with a straight-edge between reference points to give a regular surface, and then sprinkled with fixing cement.
- Dampen slightly the underside of the paving before laying, but do not soak it. Work from the paving already laid.
- Tamp the paving into place with a wooden block. The paving must have a slope of 1:00 to 1:50 to evacuate rainwater.

LAYING POOL COPINGS
- Copings elements must be laid and fixed on an underlying base wide enough for stability.
- They must be laid on lean mortar sprinkled with fixing cement, like the paving.

JOINTS
- We do not recommend laying to touch edge to edge.
- To be in accordance with technical recommandations, the paving should be laid with 10mm joints filled with firm mortar. The best solution is to use Weser-Mix JL mortar available in Bathstone and Portland, giving joints a similar colour to the paving and the coping.
- The joints must be filled very carefully using a small trowel, at least 24 hours after laying the paving. Never grout the joints. To avoid staining the paving, clean off any excess mortar with clean water.
