Terrain Solvent Weld jointing method

This video provides a step by step guide for solvent weld jointing of Terrain PVC products.

Terrain systems are easy and quick to install with a fully accredited wide range of solvent and push-fit soil and waste solutions.

When fitting the solvent-weld systems, it is important to make adequate allowance for thermal movement. This is most easily achieved by fitting an expansion ring seal joint between two fixed solvent-weld joints. The expansion gap should be created by pushing the spigot fully into the ring seal socket, and marking the position at the socket face. Then withdraw the spigot by 10mm. Check subsequently to ensure that the expansion gap is not lost during further installation work.
