When dealing with soft foundation soils - where expensive piling and other deep ground improvement solutions are unviable or too costly - the Tensar Stratum Cellular Foundation Mattress System provides an alternative approach for construction, often delivering time and cost savings. With TensarTech Stratum, there is usually no need for excavation and removal of subsoil as the cellular foundation mattress is constructed directly over the weak soil and filled with granular material to create a competent mattress system. 

Components used to fabricate the TensarTech Stratum system include transverse geogrid diaphragms, diagonal geogrid diaphragms, base geogrid and ancillary items
