Which Foundation Waterproofing Method is Right for you?

How to Choose Between Interior & Exterior Basement Waterproofing?

When it comes to basement waterproofing, there are two main methods to consider – interior versus exterior. Both of these options have their own benefits and drawbacks, so it is important to understand the differences between them in order to make an educated decision on which is best for your home.

Internal basement waterproofing is not technically waterproofing, but rather a this technique is designed to mitigate basement water. Interior waterproofing involves removing about a foot-wide section of the basement floor around the foundation. A trench is then dug out, a drainage membrane is installed on the foundation wall and a weeping tile is placed. The trench is then filled with 3/4 grovel and new concrete is poured in. 

How Interior Basement Waterproofing works - this waterproofing system works by draining the underground water from under the basement and alongside footers. The water is then channeled with a weeping tile to the sump pump that pumps the water from the basement outside. While wall conduits like dimple boards are attached to the foundation wall and extended over the new drainage to guide any moisture down into the system.

The downside of the internal waterproofing method is that it does not address potential structural issues with the foundation and does not protect against flooding.

Exterior Basement Waterproofing - the specific methodology that we follow for exterior basement waterproofing will vary on a case-by-case basis. However, in example of a house with a poured concrete foundation exterior waterproofing will involve excavating around the foundation 4” below the top of the footing. The walls will then be cleaned and dried using a propane torch. After that, the foundation walls will be inspected for cracks, holes, and openings and the imperfections will be fixed. We then apply a sealing process exclusive to Aquamaster Drain Plumbing & Waterproofing Inc. Weeping tiles & cleanouts are installed and downspouts pipes are disconnected. The entire trench is then backfilled with river-washed gravel & excavated soil. Landscaping is done. See our unique exterior basement waterproofing process in the FAQ section below.

The best solution for your home will depend on the specific needs of your home and your budget. If you are looking for a long-term solution that offers more comprehensive protection, exterior waterproofing is the way to go. However, if you are looking for a more cost-effective solution that only needs to address seepage and minimal structural issues, interior waterproofing may be a better choice.

Basement Waterproofing Reviews

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
