Soil stabilization

Underpinning and mini-piles

Settling of existing structures due to poor fill materials and inadequate soil compacting can be stopped with high strength polyurethanes and cements. De Neef chemists have engineered several unique materials and application systems for permanent soil solidification and stabilisation.

Difficult applications do not scare us: We will commit our know-how.

Diaphragm and Cut-off walls

Soil stabilisation stops contaminated water leaching from a polluted landfill or entering into an excavation. Even extreme water flow, through granular strata, can be controlled with proper method and material selection. Safely solve geotechnical problems with De Neef acrylates and polyurethanes even in combination with micro-fine cements. Large voids or cavities can be filled and stabilised with organomineral resins, resulting in a monolithic structure.

Tie-back anchors

Conventional cement tie-back grouting presents many difficulties in high groundwater conditions. Problems like grout washout and low tensile strength are nonexisten with De Neef Hydro Active Grouts. Accelerated polyurethanes can develop design strength in minutes, with little washout, due to their foaming reaction.
