Cracking can be effectively prevented by lowering the temperature of the fresh concrete.Cooling takes place in most cases via cooling of the concrete constituents, the addition of ice or via direct cooling of the fresh concrete in the truck mixer.
Where other types of construction pit sealing are out of the question, soil freezing is an effective method:
The sealing method is the only one whose effectiveness can be objectively measured. This gives clients and construction companies the guarantee of reliable tightness and strength.
In the field of civil engineering and hydraulic engineering, groundwater-bearing layers are often intervened. This water accumulates, which must either seep or be supplied to an on-site preflooder. The problem: Contact with concrete changes the chemical properties of the water. The most significant impairment is the increase of the pH-value.
