Crouting

Where underground structures are present, there is the potential for water infiltration. Whether it's running water into manhole structures and chambers which can add additional flows to sewerage systems and overload pump and treatment plants, or ground water infiltration into utility chambers for telecommunications or hydroelectric which can cause damage to live utilities, Dassyloi Inc. have become experts in water stop and infiltration control.

We use a range of environmentally-friendly polyurethane grouting resins with high mechanical strength, offering physical properties specific to the requirements of the job at hand, including chemical resistance, flexibility or rigidity, and hydrophobic or hydrophilic in nature. All our resins are certified NSF 61 for use in potable water systems. Whatever the job may be, we will use the resin that will deliver the best possible results.

Applications :

• Active infiltration waterstop
• Infiltration control
• Void filling
• Soil stabilisation
• Pipe abandonment
