Starting to notice cracks?
Small cracks in foundation walls are common in homes throughout the Delaware & Maryland area. Usually a side effect of the natural curing process of concrete, these cracks usually do not threaten the foundation. However, even small cracks in a foundation can be a major problem if they leak groundwater into your basement or crawl space.
How and Why?
We start by sealing the crack with a high-viscosity polyurethane polymer. This gets deep in the cracks to form a durable, flexible seal. At DryZone, LLC, we recommend the FlexiSpan® Foundation Crack Repair System to repair your leaking wall cracks. It's a patented, warrantied repair and a permanent solution.
Why FlexiSpan® over Injection?
Unlike hydraulic cements and some epoxies, the special sealant used for FlexiSpan® will never dry out or re-crack over time. Additionally, hydraulic cements, epoxies, and even urethane injections are not able to bend and stretch along with your foundation movement. As concrete walls expand and shrink slightly through freeze/thaw and wet/dry cycles, the bonds of these materials will fail and the crack will releak. FlexiSpan® stays bonded with wall movement, and seals the crack permanently, no matter what.
