Project overview
Water intrusion often starts with a single foundation crack, but left untreated it can lead to recurring leaks and moisture problems. Today our crews completed foundation crack excavation and exterior waterproofing repairs at two different homes—one in Davenport and another in Eldridge, Iowa.
The Davenport project involved repairing leaking cracks in a poured concrete foundation. In Eldridge, our crew excavated and repaired multiple leaking areas, including a foundation corner and an additional wall crack, to help stop water intrusion at its source.
At Behncke Construction, we focus on repairing the cause of the leak—not simply covering up the symptoms inside the basement. Every home is different, so we perform a thorough inspection before recommending the right repair.
If you’ve noticed water entering through a foundation crack or damp basement walls after heavy rain, we’d be happy to provide an honest evaluation. Contact Behncke Construction today for a free estimate.
Project details
Both repairs were exterior. In Davenport, leaking cracks in a poured concrete foundation were excavated and sealed from the outside. In Eldridge, the crew opened up and repaired multiple leaking areas, including a foundation corner and an additional wall crack. Sealing from the exterior — where the water actually enters — stops the leak at its source rather than just managing it inside the basement.
What homeowners should know
A lot of basement water starts as a single foundation crack. Water finds the crack, works through the wall, and shows up inside — and once that path is open, every heavy rain tends to make it worse.
There are two ways to handle it: seal the crack from the inside, or excavate and seal it from the outside where the water enters. Exterior repair addresses the source directly and is the more durable fix for a leaking crack, especially where there are several cracks or a leaking corner. The right call comes from inspecting the actual cracks first, not guessing from inside.
