Ground consolidation

Ground consolidation through the remedial installation of a loadbearing layer is a technique mainly used in road construction, for special geotechnical works or below foundations. It serves to guarantee lasting structural stability, ensure frost resistance or even out different settlement zones. Moreover, extreme weather events, e.g. heavy precipitation, flooding or long periods of drought, may upset the natural moisture equilibrium in many pervious soils. This may lead to undermining by water, settlement or the creation of voids and fissures that impair structural stability or even trigger building subsidence.

Targeted injections with RASCOflex acrylates or polyurethanes provide a means of counteracting these processes. Here, the injection products act as binder and filler in consolidating the existing soil structure.

For such applications, acrylates offer key advantages over polyurethanes: the low viscosity of acrylates enables them to penetrate more deeply into the soil and thereby fill even the smallest cracks and interstices. Alternatively, depending on the product, they may serve only to "spot bond" the rock or soil particles.
