Waterproofing & Water Damage Solutions in Markham

Looking for a waterproofing solution that’ll keep your home dry and protected? At DGI Waterproofing, we have a variety of waterproofing services that can help protect your property no matter the time of year.

2025 Waterproofing Rebates

If you have a wet basement or are in the flood prone areas like Markham West or Toogood Pond, you might be able to get some financial aid for basement waterproofing. Unlike other cities in the GTA, they run their own Private Plumbing Protection Rebate Program, which helps homeowners with the financial burden of getting waterproofing solutions like installing weeping tiles and sump pumps.

While this rebate is great for those who need financial aid and live in flood prone areas, you must first make sure you are eligible and properly go through the application process, with all the details being available on their website.

Rebates for Weeping Tiles & Sump Pumps

Unlike Toronto’s Basement Flooding Protection Subsidy Program, this program combines both weeping tiles and sump pumps under one rebate, meaning you have to get both services for this rebate. The city provides a rebate of up to $5,000 for disconnecting weeping tiles and getting a sump pump installed.

Soil Type in Markham & How It Affects Local Waterproofing Services

Some areas like being near Rouge River or Toogood Pond are more prone to flooding, and that’s because of the floodplains. If you live in those areas, you know how bad the high groundwater gets during heavy storms or spring thaw, which means your basement is going to be under constant pressure from the surrounding soil.

The soil is largely made up of clay and silty ( soil with the texture of something in-between sandy and clay) deposits, both of which hold water for extended periods. When it’s wet, the soil puts extra pressure on your foundation walls since it expands, which can cause small cracks or bowing that lets water in. When the soil eventually dries up, it shrinks and pulls away from your foundation, which then leaves a gap or pocket for water to sit in.

Helpful Waterproofing Services

  • Underground Downspouts: During heavy rain, this helps push all that excess water away from your home.
  • Sump Pumps: Your basement’s first line of defense, being super effective by getting rid of excess water.
  • Epoxy Injection: One of the most common and reliable ways to patch up a crack on your basement wall.

Factors That can Affect Waterproofing Costs

There’s multiple factors that goes into determining how much waterproofing your basement would cost like the soil around your home, history with water damage, and how prepared it is for rainstorms. No matter if you’re in Unionville, Cornell, or nearby, each factor plays a role in the type of protection you need.

  • Foundation Size: Of course the larger the basement means there will be more materials used, and more work that needs to be done.
  • Floodplains Nearby: Homes in or near designated floodplains, like those along the Rouge Valley, are more exposed to higher groundwater. This means your waterproofing solution will need to be more robust for proper protection.
  • Having Mould: If you have mould, then this needs to be addressed before any work can be done. Our team needs to professionally remove it and conduct air quality testing, all of which add to the overall cost but are essential for a healthy basement.
  • Improper Drainage: Many homes in the area have outdated, clogged, or missing weeping tile systems. If water isn’t being directed away from your foundation properly, fixing the drainage is step one.

How To Prevent Future Water Damage

Thanks to the clay-rich soils and floodplains near the Rouge River and Toogood Pond this can make it so you experience moisture issues a lot more than you’d like. In order to prevent future water damage and expensive repairs, you should be proactive by taking action before a flood happens.

  1. Interior Waterproofing: Applying a waterproofing membrane to the interior of your basement walls is a common solution if your foundation is hard to access.
  2. Patching Foundation Cracks: Even tiny cracks can become major entry points for water, especially as the silty and clay soils expand and contract with the seasons. We make sure to patch them up so no water can get through.
  3. Exterior Waterproofing Membrane: This is one of the most reliable ways to prevent water from getting to your foundation walls in the first place, effectively shielding your exterior from moisture.
  4. Mould Remediation: We remove contaminated materials, treat affected areas, and help prevent it from coming back, protecting your family’s health and your home’s air quality.
