Leaking Basement Crack repair

Why Concrete Cracks

Concrete shrinks as a natural process of it curing. This shrinkage causes the concrete to institute stresses and to relax it, the basement wall cracks. This is a general condition in a concrete foundation. Shrinkage cracks are typically less than 1/16th" in width and will ultimately run the entire distance of the concrete wall, from top to bottom. Coarse areas for a shrinkage concrete crack to institute are under a basement window, in the middle of a long wall or where the foundation "steps down."

DRYWALL SETTLEMENT

Once the concrete cracks it is possible for water to leak into a basement straight through the crack. There are several ways to fix a basement crack leak. The most productive is to achieve an injection of polyurethane foam into the basement crack.

Polyurethane Foam Injection

Polyurethane foams are injected into the basement crack in a liquid form. This allows a diplomatic and slow filling process of the basement crack that will completely fill the crack. After a few minutes the polyurethane will begin to react with the water in the crack to begin foaming. Water is indeed the catalyst that converts the liquid polyurethane into foam. This foaming activity increases the volume of the polyurethane up to 30x its liquid form.

As the polyurethane foam expands it fills the basement crack from lowest to top and front to back. The complete foam will be a complete cell structure that will not allow water to leak into the basement crack. In fact, if there are any voids in the soil outside of the basement- such as under a rock or if the foundation is backfilled with gravel-the polyurethane foam will strengthen and increase out into the void.

The polyurethane foam forms a strong bond to the concrete. This bond will be able to withstand the hydrostatic pressure that may institute from high ground water levels. High ground water levels are typically caused by heavy rains.

Why Polyurethane is good Than a Patch

No other concrete crack fix process can do what polyurethane injection can do. outside patching of the crack is just that. Only the inside of the basement wall is covered by a repair. Chiseling out the crack and filling it with hydraulic cement only fills a part of the crack. Water can still enter the basement crack and will ultimately force out the patch or hydraulic cement.

Fast and Easy Repair

Basement crack injection is a quick fix process that stops water leaks. The technician does not have to drill into the concrete to do it. For this surmise the basement crack fix is a clean process. The technician will attach ports to the outside of the basement crack that allow the liquid polyurethane to enter the basement wall and stop the leak.

Once the basement wall crack fix is completed, water will not be able to leak into the basement. Now the homeowner's possessions will be safe. As will any insulation on the basement walls, the drywall or the framing used to desist the basement.
