how to fix a crack in your basement wall leaking water.

- If you have a crack in your basement wall leaking water, you need to call in a professional foundation crack repair company. Otherwise, those cracks can grow larger and continue to leak water into your basement. This can lead to increased humidity, mold growth, water damage, and more. Here’s how experts do it:

•  Epoxy crack injection – Experts can fix cracks using epoxy injections that seal, waterproof, and reinforce your basement walls. First, a surface patch is created using an epoxy bonding solution. Then, the 2-part special epoxy is pumped into the cracks until it fills the voids. 
•  Carbon fiber staples – First, slots are grinded into your basement wall along the crack. Then the high-strength carbon fiber staples are inserted into the cracks and fused into the concrete using an epoxy. These staples will prevent the cracks from growing larger. 
•  Exterior crack repair – If you have a finished basement and you don’t want any drywall removed, experts can fix leaking cracks from the outside. First, they dig outside your foundation and clean the area around the crack. Next, they apply hydraulic cement along and inside the crack. After that, an elastomeric waterproofing tar is applied all across the crack. Lastly, they apply a vapor barrier or an insulation board to protect the tar as they return the dirt. 

 There are two types of cracks that might form on your basement wall: structural and non-structural. Structural cracks are more serious and are usually caused by differential settlement. That’s when sections of your home settle at different rates. 

 Non-structural cracks are less serious but can still allow water to seep through your walls. Non-structural cracks, also called waterproofing cracks, can form over time due to natural aging, or they can form when your concrete walls dry too quickly after they are poured. 

 Experts recommend sealing both cracks in order to stop water seepage. Structural cracks might require more work to solve the root of the problem. For example, your home might be settling into the soil beneath it and may require underpinning. If outside pressure is pushing against your basement walls, experts might install wall plate anchors or carbon fiber straps to pull your wall back outward and stabilize any further movement. Once these issues are addressed, experts can move on to filling in the cracks.
