Cracks in drywall are common in both new constructions and older homes. Smaller cracks can start to appear as the foundation of the house settles into the soils upon which it was built.

Bowing Walls

Identifying a bowing wall is not always the easiest. If you have a wall that is showing signs of inward movement, repair work is required, not recommended.

About Us

Shane Isham, the owner of IWP (formerly Isham Waterproofing), started his waterproofing career in 1992. Shane has personally performed each and every task that his team is required to do throughout his career so that he knows not only the best products to use but how everything works and changes over time. IWP has a full crew with specialists for each discipline.



Top notch business from the guy who inspected my basement to the crew who did the work!!!
I got 3 estimates for the work I wanted done on my basement wall. (Waterproofing and the wall braced and pulled out.) The rep for IWP was the only one that listened to how I wanted the work completed. The other 2 tried to convince me that their way was better because they wouldn’t dig up my yard.
My basement wall had moved in 3 1/2 inches. When IWP was finished they had pulled it out almost 2 inches!
The before picture was taken 3 days before IWP began. The after picture was taken the day after the work was completed.

Camden was very professional and took time to explain what he was looking for on the basement wall and how soil expands and contracts etc. I really appreciated that! So nice to have someone who is courteous, knowledgeable, and honest in their assessments!

Shane and his crew just completed shoring up a broken basement wall. It looks better than it did new! They are 100% professional and dependable. They cleaned up the piles of concrete and dirt, you would never know there had been any work done, except for the beautiful work on the wall. Call them, you will not be sorry.

Great company to work with! Very pleasant owner and employees!
