Expansion of the geopolymer will compact the soil by minimizing voids and improving the internal friction angle in granular soils. In clay this occurs mainly as soil displacement by replacing the existing loose soil zones with stronger geopolymer. Monitoring is carried out with a laser on the surface/structure to assess movement/lift.

Yes – Groundtek materials are hydrophobic.

there is no difference between exposing the material to sea water vs fresh water.

Typically We recommends that existing loads are left in situ to provide counter-force – for example, where possible racking should be left loaded whilst treated to ensure we achieve the best end result.

The material cures within seconds.

90% of the materials’ mechanical properties are reached within the first 15 minutes.

The material typically reaches its final properties in 24 hours.

Design life in excess of 100 years.

Material has been tested and is evaluated to be stable for a minimum of 60 years.

Proven practical results with over 30 years of project applications.

Material stable between -20 to +100 °C.

This will depend on the material, the circumstances and the density.

The material has some elasticity, which is typically positive – for example when comparing to

concrete which may break down under shock loadings.

Outside temperatures have no impact in most cases. The material is always injected below the frozen zones, not in it.

Yes it is possible and can be done with normal excavators and hammer drills.

This will depend on the material, the circumstances and the density.

The material has some elasticity, which is typically positive – for example when comparing to concrete which may break down under shock loadings.

Dynamic cone penetrometer test, medium weight (DPM) and soil sampling.

Typically < 15% of the soil, depending on the geopolymer utilised and the existing soil.
