Injection of Resin/foam

Injection is a proven method of sealing against pressurized water in structural renovations. The grouting of injection hoses also provides the benefit of using the advantages of injection technology in new construction specifically for the sealing of construction joints. Reusable injection hoses, which can be injected several times, have been used successfully for construction joint sealing for many years. They can be injected with micro fine cement, polyurethane resin or acrylate gel.In contrast to passive sealing systems such as conventional water stops and waterstop sheets, which only seal off due to the so-called circumference extension, active systems such as injection hoses and injection grouts can be used to cancel out possible weak points in the concrete caused by cracks or badly compacted concrete.
