Options & Considerations When it Comes to Basement Waterproofing

What is Included in Basement Waterproofing Services?


The ideal solution to stem water damage, or to prevent excess water from getting past the foundation into the basement. However, external waterproofing does cause disruption to the outside of the home. The soil and underlying gravel have to be removed in order to get a close look at defects on the outside of the foundation. The foundations is then powerwashed & dryed the foundation walls, cracks are uncovered & fixed. A flexible, cement sealant is applied to all the exposed areas of the foundation. Then a heavy polyurethane drainage mat is attached to the exposed walls. This extra protection on the outside ensures the foundation will ward off any excess buildup of groundwater.

Sump pumps are often a part of the internal basement waterproofing system. Sump pumps are used to remove the water that was collected in your basement. If the sump pump fails to properly remove water from around the foundation of your building, it can cause flooding, water seepage into the basement, and damage to the foundation walls. In addition, a broken sump pump can cause mold and mildew growth, and drainage blockages, and create the ideal environment for pests and insects to breed. The best thing to do is to regularly check your sump pump and replace it at the first sign of any problems. 

Emergency Basement Flood Repair

Basement water damage are tough to handle, it's even harder when you have a basement flood. Our flood restoration experts will help quickly assess the basement damage and will use commercial-grade blowers and dehumidifiers to prevent further damage to your property.

Weeping tile installation and weeping tile cleaning services are crucial parts of making sure your wet basement problems are solved. A weeping tile drainage system will help collect water around your foundation and will direct it away. This way the amount of water around your basement is reduced which can help reduce the damage it can do to the foundation walls and your basement.

Also known as interior waterproofing is another approach to solving the damp or wet basement problem. It typically involves applying a waterproof coating or membrane to the inside of a building or other structure, such as a basement, crawl space, or foundation walls. This waterproofing helps prevent excessive moisture from entering the structure, which can cause a variety of problems, such as mold growth, structural damage, and decreased insulation. In addition to preventing water damage, interior waterproofing can also help reduce energy costs by making the space cooler and more energy efficient.

Also known as basement underpinning services. Is an excellent way to turn your basement into a comfy living space. Basement lowering will create additional space in your basement and is a smart investment before finishing the walls and ceilings in your underground cosy space. Both floors lowering and basement waterproofing services are a great way to increase the value of your home.

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 technique 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.
