Basement Wall Crack Repair

A basement wall crack can let water leak in and flood your basement when concrete cracks. This water can cause mold and mildew to grow in a basement, causing an unhealthy environment in your home. By stopping water that leaks through a foundation crack, a basement can stay dry. In conjunction with foundation drainage, a quality sump pump and sealed sump pit, basement wall crack repair is one step to a complete sealed waterproofing system.

Basement wall cracks are the number one cause for basement water problems. Water from the soil builds up the pressure and over time finds the path of least resistance into your basement. Foundation cracks are often caused by this buildup, known as hydrostatic pressure. Cracks in foundation or basement walls are an easy way for water to enter your home and create problems.

There are three guarantees when it comes to poured concrete walls.

  • The concrete will get hard
  • The concrete will crack
  • The concrete wall will not be stolen

Even though concrete cracks appear to be normal, it is not recommended that they remain ignored. Most homeowners have concrete cracks in their basement, either on the foundation wall or on the floor. If there are water puddles or water stains around these cracks, you need to address them immediately. More often than not, a foundation crack will grow over time and result in water seepage and possible structural damage. Foundation and slab cracks are not only an eyesore, but they may damage the value of your home.

Fortunately, there is a way to permanently repair such cracks quickly and effectively. Concrete foundation cracks may be repaired by using pressure injection of an epoxy or polyurethane foam material. For the repair of concrete floor cracks, certain epoxies and polyurethane materials exist, suitable for such slab repairs.

High-quality epoxy and polyurethane products, injected by a waterproofing contractor, is very effective in repairing cracks. Crack injection techniques are relatively simple, yet not recommended by an untrained person. Many foundations have been greatly damaged by untrained crack injection techniques.

Epoxy Crack Repair

Epoxy crack injection is known as concrete welding. The bond that epoxy creates becomes stronger than the basement walls themselves. Epoxy products also have the inherent ability to fill even the smallest of wall cracks. Low viscosity epoxies penetrate all the way through basement wall ruptures ensuring a complete repair.

The number one advantage of epoxies is their very high compressive strength. Because of this strength, engineers often recommend epoxy injection for structural foundation repairs. Epoxy resins are used for everything from bridge and highway repairs to residential basement repairs. This process of basement wall repair seals the foundation and creates an impervious barrier to basement water seepage.

You must remember that epoxy injection crack repair does not remove or control the source of the water problem. It is very important to identify and solve the water source to permanently stop water seepage. Professional waterproofing inspectors will work with you to determine the cause of concrete cracks and the surface water control solutions to solve them.

Polyurethane Crack Repair

Polyurethane crack repair has a unique advantage of epoxies repairs due to the fact that it remains flexible. If you experience slight foundation movements, polyurethanes will flex and still keep the crack sealed from water. While they have almost zero compressive strength, polyurethanes are very popular for basement wall repairs.

Probably the most popular feature of some polyurethane products is their ability to stop actively-leaking cracks. These types of polyurethanes set up very quickly and actively seek water to react with. Once this reaction takes place, they very quickly foam and seal voids and cracks while remaining flexible against movement.

You must remember that polyurethane injection crack repair does remove or control the source of the water problem. It is very important to identify and solve the water source to permanently stop water seepage. Generally, the first step is to control surface water sources.
