NZ Foam Geotecnical Foam

These specially designed and field proven polyurethane foam systems are used when a lightweight spray or injection fill is required over conventional lightweight concrete mixes, or polystyrene blocks. High strength, low, medium and high density, low exotherm and fast application make this the system of choice when filling utility trenches, expansive void area under concrete slab sections or filling expansive areas with already loose, or questionable, soil load bearing characteristics.
