How to lay clay paving
Wienerberger clay paving products can be easily laid by a DIY enthusiast, or your stockist can provide details of a local paving contractor. The following covers some basic principles of installation, and full laying details are available on request.
Step 1 Sub-base
A sub-base is essential for driveways or areas for vehicular use and should be constructed using a Type 1 stone sub-base material compacted to a depth of at least 150mm. An existing drive can be used as a base, providing that it is sound and the finished paving level will be at least 150mm below the house damp proof course level. For general garden areas, a sub-base thickness of 75-100mm is recommended. If you are unsure, seek advice from your contractor.
Step 2 Edge restraint
A permanent edge restraint around the perimeter is necessary to keep the finished paving firmly in place and stop any spreading. This may be provided by existing structures such as walls; if not or if you would like to make an attractive feature of the edging in its own right, you can choose from purpose-made curved or angled edgings. It is important that edgings are bedded and jointed together with mortar.
Step 3 Bedding course
Prepare a bedding course using bedding sand, compact it and screed smooth to the desired level, before laying pavers on clean, sharp, natural sand, compacted using a small plate compactor to an even depth of 50mm.
