What Is Interior Basement Waterproofing?

Interior basement waterproofing is an effective solution for managing water that has already entered your basement. In cases where exterior waterproofing isn’t possible, whether due to higher costs or limited space between properties, interior waterproofing solutions become essential.

When rain or snow melt pushes against foundation walls, water finds weak points to enter the basement. Interior waterproofing protects your property by collecting and redirecting water to a sump pump, which removes it from your home before it can cause damage. This process ensures your basement remains dry and reduces the risk of mould, structural damage, and other water-related issues.

How Easy Is It to Install an Interior Basement Waterproofing System?

While interior basement waterproofing is a bit less complex than installing an exterior system, it’s still challenging for non-experts to install. Hiring professionals like the Aquamaster Waterproofing team ensures the job is done right — your waterproofing system will capture and redirect water effectively, and your sump pump will work flawlessly when needed.

Our Interior Waterproofing Services in Toronto

Each interior waterproofing project is unique, so we customize solutions to your specific needs. Here’s an outline of the key services we provide:

Crack Repair

Cracks in basement walls or floors can be potential entry points for water. Interior basement waterproofing may involve filling these cracks with high-quality sealants or epoxy injections to prevent water seepage and protect your foundation.

Basement Sealing

Basement sealing involves applying multiple layers of waterproofing materials to the interior walls and floors of the basement. Contractors use specialized waterproof coatings, sealants, or membranes to create a durable barrier that prevents water from seeping through the walls or floors.

Interior Drain Tile System

This involves installing a drainage system along the edge of the basement floor. The drain tile system collects water that enters through the basement walls or floor and redirects it to a sump pump or a gravity drain. 

Sump Pump Installation

sump pump prevents flooding by redirecting water away from the foundation, protecting your property from flooding and water-related structural damage. It is installed in a sump pit at the lowest point of the basement, allowing it to automatically detect when water levels are high and pump the water away from the building.

Dehumidification

Installing a dehumidifier is a practical solution for controlling moisture in the air. These devices extract excess water vapour, improve air quality, and create a healthier and more comfortable environment in your basement. Dehumidification helps to reduce humidity levels in the basement, preventing the growth of mould and mildew and creating a more comfortable environment.

Interior basement waterproofing only manages water that has already entered the basement. If water issues stem from external sources, such as poor drainage, grading, or foundation cracks, you may have to address those issues through exterior waterproofing methods to prevent water from reaching the basement.

Frequently Asked Questions

Here are the answers to some frequently asked questions about our interior waterproofing services in Toronto.

Each property has unique needs, which is why we customize our interior waterproofing solutions based on the condition of your basement and the components of your existing waterproofing system. Here is an example of an average interior waterproofing project:

  • Preparation: Our team protects your property by covering the work area to minimize dust and debris.
  • Foundation assessment: We use camera inspection where needed to assess the condition of your foundation wall, and we thoroughly inspect for any pre-existing cracks.
  • Trenching and drainage setup: We create a trench along the interior basement perimeter, install a Delta-MS membrane to capture water, and use high-quality weeping tiles (porous pipes) that connect directly to your sump pump system.
  • Sump pump installation: Our team will install a sump pump and handle all permits to ensure rebate eligibility where available.
  • Quality assurance and finishing: Every system undergoes a full QA test to confirm functionality, and we use clean gravel to encase weeping tiles before re-cementing the floor for a smooth, clean finish.

Interior waterproofing costs range from $70-$350 per linear foot, depending on the specific services involved. An average project costs between $15,000-$30,000 or more. Learn more about the price of interior waterproofing.

Interior basement waterproofing can take between one day and two weeks on average. If you only need to repair a few cracks, this will take less time. If you’d like to set up a full-scale interior waterproofing system with a sump pump, waterproofing basement walls, drainage system, and more, this will take longer.
