Less than a tenth of the weight of typical soil or hardcore, TECHNOpor® is an excellent fill material for landscaping on carpark roofs (see right and below) and green roofs. Due to its closed cell structure, TECHNOpor® lightweight aggregate is free draining. And, as it has a high coefficient of friction, it is ideal for slope stabilisation and, again, roofs; TECHNOpor®, when compacted, is stable at 45degrees, but even uncompacted can be applied to surfaces at 15degrees.
TECHNOpor® glass foam aggregate has been used to form an insulating floor slab supporting lime flooring in strawbale housing [see diagrams below from Straw Works – Partners page]. Similarly, it can be used to support and insulate timber frame structures; TECHNOpor® has a compressive strength of 500kN/m2, meaning loads of 50tonnes/m2 present no problem [see Technical Info page].
Given its attributes of strength and light weight, TECHNOpor® makes an excellent fill aggregate to reduce the loading on retaining walls, to combat slope instability, or to sure up poor/wet ground conditions. TECHNOpor® is free draining, due to its closed cell structure, and thus makes an excellent aggregate for french drains. Combine these two benefits and you have an insulating, free-draining, load-reducing backfill to basement and ground-level external walls for wet, sloped and poor ground conditions.
