01Oct92 UK: CEMOSS LAUNCHES ITS CLAYLITE SUPER COMPRESSIBLE FILL MATERIAL.

Claylite Super is a new compressible fill material from Cemoss for trench lining applications in difficult earth conditions.The material combats earth movements to reduce the risk of pressure problems on foundations. This is achieved by means of a corrugated, flexible membrane which is bonded to the inner face of the trench sheets.Claylite Super is claimed to be better than normal compressible fill materials in resisting breakage due to uneven trench walls or protruding objects. It is also said to overcome difficulties of fixing low density soft matertial firmly to trench walls.In the new system, purpose made earth bolts are used to retain the fluted plastic sheet in place against the trench wall and also prevent movement when the concrete is poured.There is no sheet breakage in its handling or fixing, which could be entrapped within the foundations, leading indirectly to in-built foundation weakness. There is also a better flow of concrete, says the company, due to the laminated face design.Protection of the compressible face allows the material to retain its thickness for better action in absorbing soil movement or surge.Better results have also been achieved using Claylite Super in deep foundations and with vibrated pours.
