How You Can Ensure Perfect Crack Repairing Now
In
the imagination of people, the problems of foundation cracks often evoke images
of houses with contours excavated to leave room for the foundation in the open
air, to repair it from the outside. However, the field of foundation crack
repair has evolved to give rise to new, less invasive techniques! Highly
efficient injection products have been developed, allowing for much more simple
and quick work by repairing the interior. This foundation repair technique
offers many advantages!

The
marketing of flexible polyurethane has led to the development of a high
pressure injection technique of this product, for the sealing of foundation
cracks. The specialist accesses the interior of the house, regardless of the
season, and can repair a crack. It is possible to proceed even if there is an
infiltration of water during the repair.
The
flexible polyurethane product, also referred to as the polymer resin,
penetrates from one edge to the other of the concrete foundation, regardless of
wall thickness. Therefore, this technique offers a complete repair of the
crack. Follow us on: Facebook
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.
