What are the advantages ?

The injection technique from the inside ensures efficiency in all conditions, in addition to being able to be carried out at any time.

The product is distinguished by excellent adhesion, remarkable flexibility and a considerable tractive force. The clogging of the crack with this product is instantaneous, guaranteeing a total repair. Because once injected, the polyurethane expands, up to seven times its initial volume. This reaction of the product takes place in twelve hours. When the polyurethane solidifies into a kind of rubber, it retains its elastic properties, while ensuring complete clogging.

This technique, which requires no excavation or turnaround, is therefore fast and affordable.

How it works ?

After examining the damage, the wall repairs specialist pierces holes at intervals of 10 to 15 cm along the crack. The holes are oriented at 45 degrees to join the crack in the middle of the concrete wall. All surfaces, including holes, are then cleaned to optimize adhesion of the injection product. An epoxy plaster is first applied. Using mechanical metal injection ports, also called injection sockets, and installed in the pre-drilled holes, the flexible polyurethane is injected under high pressure. This maneuver is performed in a movement from the bottom of the foundation upwards.
