Ground freezing

Ground Freezing

In very specific situations to improve impermeablity and/or achieve greater soil strength.

Ground Freezing is another specialist technique we offer which works on the principle of freezing the water in the soil, thus rendering the soil impermeable and of greater strength.

The soil is frozen by the transfer of calories from the ground to a low-temperature fluid circulating through a probe drilled into the ground. The ground water freezes and forms a mass of frozen soil around the probe. The accurate design and positioning of the probes is essential for the success of this technique.

The most common uses of ground freezing are for shafts, cross passages between tunnels, safety niches and excavation beneath sensitive structures.
