SmartSeal-Injections-Foundation Repair


SmartSeal injections performs Polyurethane Concrete Foundation Crack Repair

Did you know? Concrete shrinks as a natural process of it curing. This shrinkage causes the concrete to develop stresses and to relieve it, the basement wall cracks. Concrete shrinkage cracks are a common condition in a concrete foundation [or also in concrete slabs unless control joints were used in the wall or floor design] and occur when concrete shrinks as it dries and cures.

SmartSeal Injections can repair a typical 8′ foundation crack in approximately 90 minutes. This is because there is no drilling or chiseling needed to widen the foundation crack. The low viscosity polyurethane can enter even hairline cracks with ease and stop your basement water leak.

Foundation crack repair is required because wall cracks in poured concrete foundations are the most common way water enters the basement.

It may seem like an easy process but it should be done by professionals with years of experience. An inexperienced installer can create huge problems if Polyurethane is misused.

For example...

If an installer uses polyurethane around a pipe, such as a sewer line, and there is a crack or small opening in the pipe, the urethane will enter the pipe, find water, and expand up to 25 times its size! This will clog the pipe and create an expensive disaster. All the drains in the house are immediately taken out of service. A plumbing company has to dig down several feet to repair the pipe. Thousands of dollars plus untold inconvenience for the home owners. 

SmartSeal Injections has 20+ years of construction experience and has repaired miles of foundation cracks.

Basement crack injection is a quick repair process that stops water leaks.

Why is polyurethane foam repair the best?

Polyurethane foams are injected into the basement crack in a liquid form. This allows a gentle 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 actually the catalyst that converts the liquid polyurethane into foam. This foaming action increases the volume of the polyurethane up to 30 times its liquid form. As the polyurethane foam expands it fills the basement crack from bottom to top and front to back. The finished foam will be a closed 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 expand and extend 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 develop from high subsurface water levels. High underground or “subsurface” water levels are typically caused by heavy rains and most-often by failure to direct roof runoff or nearby surface runoff away from the building.

SmartSeal Injection’s concrete crack repair process using polyurethane injection is likely to be more successful and more durable than other crack patching methods. Surface 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 portion of the crack. Water can still enter the basement crack and will eventually force out the patch or hydraulic cement. [Forces that tend to cause separation of poorly-bonded concrete surface patches include the molecular action of crystallizing mineral salts left behind as moisture passes through the masonry wall.]

Our basement crack injection is a quick repair process that stops water leaks. Our technician does not have to drill into the concrete to do it. For this reason our basement crack repair is a clean process. SmartSeal Injections will attach ports to the surface of the basement crack that allow the liquid polyurethane to enter the basement wall and stop the leak. Once the basement wall crack 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 finish the basement.

A quick and effective measure to stop basement or crawl space water entry.
