Groundwater barrier
Geofrost provides groundwater barriers to limit the contaminated area and prevent spreading through the groundwater.
The frozen groundwater barriers become completely waterproof, regardless the type of ground conditions, and are therefore very reliable and efficient. The barriers have flexible shape and can be installed in-between pipes, cables and other obstacles and toward other construction elements in the ground, independently of irregularities in the surface.
Freeze dredging
Geofrost provides freeze dredging for removal of contaminated sediments in lakes and harbors. The contaminated sediment layer is frozen and then brought up as frozen blocks. The method provides minimal spreading of contamination in and outside the water, good control of removed sediment thickness and minimizes both water volume to be cleaned and contaminated soils to be deposited.
Benefits
Reliable
Frost has the property of extending through any kind of ground condition and material, and therefore extend around any bodies, completely sealing towards uneven surfaces and around crossing pipes and cables and give a reliable result each time.
Minimal spreading
Contaminated soils which are frozen get incapsulated and will not spread in water or air. This provides safer handling and ensures minimal spreading.
Minimal volume
By isolating the contaminated soils, the volumes to clean and deposit are minimized.
