Soil Stabisation

Unstable, loose soil and erosion can be detrimental to  a number of  structures including buildings, bridges, roads and underground civil infrastructure. It can lead to settlement and damage to the structure due to large voids beneath it, loss of bearing in soil and overall instability of soil. Using patented ultra-low viscosity polyurethane resins, voids can be filled, soil consolidated, erosion halted and soil bearing improved.

Stabilisation Uses

Using Alchemy Spetec single component, water activated, hydrophobic, low viscosity, closed cell polyurethane injection resin, we can provide a solution for all types of soil stabilisation requirements including:
  • Soil permeation grouting
  • Stabilising loose sand and soil
  • Sinkhole remediation
  • Filling voids behind concrete structures
  • Cutting off high flow leaks
  • Cutting off underground water flows
  • Increase load bearing capabilities

Permeation Grouting using polyurethane can ensure stabilisation, consolidation and binding of soils. Through permeation injection of polyureathan resin in a gridded/sequenced pattern creates a solid mass of soil and rigid resin (ideal for silty and sandy soils). The displacement of water and the resulting solid soil/resin mass reverses the erosion process and improves soil stability and soil bearing capacity.

We provide these services for the residential, commercial and civil (roads) sectors. Applications include
  • Bridge approach slabs
  • Sinkholes or voids under slabs due to loose soil
  • Driveways
  • Loose sand/soil
  • Increasing of load rating of existing warehouse slabs

Utilising the experience and expertise of Alchemy Spetec, American based manufacturer of the polyurethane resin and foam, we have custom built injection rigs and have access to training and expertise to eventually become industry leaders in Australia.
