PRODUCT
INFORMATION
With its high strength-to-weight ratio and ability to withstand mechanical loads, S and B EPS Geofoam fill can assist in reducing the pressure on soils when taking into account the high unacceptable loadings that can be present, whilst offering a proven economical alternative to piled construction.
S and B Geofoam fill blocks offers a cost effective lightweight solution that takes away the problem of unacceptable stresses encountered when using traditional fill materials and reduces the probability of settlement.
Traditional fill materials can be liable to unacceptable settlement when used on railway embankments.
S and B Fill with its high strength-to-weight ratio offers a cost effective solution to loads encountered in railway construction.
