The process is basically a permeation grouting technique. By filling the pores of a granular soil, with a resin (whether polyurethane or acrylate), we are able to bind the soils together, to form a stabilised mass of soil, with vastly improved bearing capacity; resulting in the soils becoming self-supporting. With the resins being hydrophobic or hydrophilic, we are also able to dramatically reduce water movement through the treated soils.
The resins are injected through bespoke injection lances at horizontal and vertical centres to suit the soil conditions. Angles and depths of lance installation and volumes of resin are pre-determined by H2Ox Engineers. The resins are then injected to form overlapping bulbs of stabilised soils. This is particularly useful in forming cut off walls in the ground, or stabilising soils in advance of underpinning; to act as support to adjoining land and provide stable working environments for excavations.BOOK A VISIT
The resins become inert on contact with moisture within the ground or even when exposed to atmospheric moisture and have been used by H2Ox on many structures throughout the UK including:
