What is your basement waterproofing solution? Can you fix leaky basement from the inside? Or is excavation always necessary?

It’s very attractive to use a sealant or coating to stop basement leaks from inside. It costs less and there are so many basement waterproofing contractors giving lifetime warranty for such repairs. But remember this is only covering the problem, not solving it for good. The water that caused the basement leak is still there and will find its way back in. Don’t believe us – read what this university study (reviewed in 2018) has to say :

“It is appealing to solve a basement moisture problem with a membrane or coating on the inside. It is less expensive than a drainage system and seems to work for a time in some cases. The water is still there, however, and eventually these systems deteriorate or simply move the water to another pathway into the basement.”

However, excavation is not always necessary.

If you see
– water coming up through basement floor after heavy rains, or
– water coming into the basement where the walls meet the floor, or
– water seeping through basement floor cracks, or
– water seeping up through concrete garage floor

then this basement leak might be fixed from the inside, by using internal drainage systems and sump pumps. See this page for more details.

”My basement is usable now. You did waterproofing at my house about 18 months back. This year it has rained a lot but there has been no water intrusion into my basement. I want to thank Todd. He and his team did the job well.”
