Why Choose Interior Waterproofing for Your Basement?

Interior waterproofing is one of the most effective ways to protect your basement from leaks, mold, and costly water damage—without the need for heavy outdoor excavation. This method focuses on controlling water from the inside by installing drainage systems, sump pumps, and vapour barriers that safely redirect water away from your foundation.

Whether you’re dealing with small foundation cracks, recurring leaks, or damp basement walls, interior waterproofing provides a long-lasting solution that keeps your basement dry, safe, and usable. It’s especially ideal for homes with limited outdoor access or finished basements, where exterior excavation is not practical.

At VHP Services, our licensed experts use advanced systems to stop water intrusion before it spreads, protecting your home’s structure and your family’s health. By preventing mold, mildew, and structural damage, interior waterproofing not only safeguards your property but also helps maintain its market value. With our proven techniques, you can enjoy peace of mind knowing your basement will remain dry and protected year-round.

Benefits of Interior Waterproofing

Protect Your Basement from Water Damage

Interior systems prevent leaks, flooding, and moisture buildup, keeping your basement dry year-round.

Prevent Mold & Mildew Growth

By eliminating damp conditions, interior waterproofing protects your family from health risks like mold spores and poor air quality.

Increase Property Value

A dry, protected basement gives peace of mind to potential buyers and increases your home’s resale value.

Cost-Effective Solution

Interior waterproofing often costs less than exterior excavation while still providing reliable, long-term protection.

Our Interior Waterproofing Process

At VHP Services, we follow a proven multi-step process to ensure your basement stays permanently dry. Each step is handled by licensed technicians using industry-leading equipment and materials.

1. Inspection & Assessment

We begin with a complete evaluation of your basement. Our team looks for water stains, cracks, high humidity levels, and signs of mold. Using advanced tools, we identify exactly where water is entering and how severe the problem is.

2. Site Preparation

Before installation, we carefully prepare the work area by moving or protecting household items, clearing flooring if needed, and ensuring a safe, clean workspace. This step prevents unnecessary mess and protects your home.

3. Trench Excavation

A narrow trench is dug along the interior perimeter of the basement floor. This allows us to install a drainage system designed to capture and redirect water before it reaches your living space.

4. Drainage & Weeping Tile Installation

A new interior drainage channel (weeping tile) is installed along the basement’s edge. This system collects groundwater and directs it safely toward a sump pit, preventing pressure from building against your walls.

5. Sump Pit & Pump Installation

A sump pit is installed in a low spot of your basement. We then place a reliable sump pump inside, which automatically pumps collected water out of your home, keeping your basement dry—even during heavy rain.

6. Wall Membrane Installation

A waterproof membrane or vapour barrier is applied to basement walls. This prevents further seepage, channels any wall moisture into the drainage system, and adds an extra layer of protection against future leaks.

7. Backwater Valve & Extra Protection

If required, we install a backwater valve on the main sewer line to prevent sewage from backing up into your basement. Combined with the sump pump, this system provides full flood protection.

8. Final Testing & Cleanup

Once everything is installed, we test the entire system to ensure proper drainage and pump operation. The work area is cleaned thoroughly, and your basement is left safe, dry, and ready for use.

Our basement had constant leaks every time it rained. VHP Services installed a sump pump and waterproofed the foundation. Since then, not a single drop of water. Professional, fast, and worth every penny!

I had cracks in my basement walls that were letting in water. VHP Services sealed them and installed a backwater valve. They explained the process clearly, finished on time, and even helped me apply for the city rebate. Highly recommend!

We hired VHP for exterior waterproofing after years of dampness in our basement. The crew dug around the foundation, installed new weeping tiles, and left the site clean. It’s been dry ever since. Amazing job!

Water was seeping through foundation cracks in our basement. VHP repaired the cracks and applied waterproof coating. They walked us through every step and even followed up afterward. Very professional.

We had water seeping into our basement wall in Ajax. The VHP crew came out, did an exterior waterproofing with membrane and weeping tile, and even patched up the concrete perfectly. Big thanks to Yuri and Vasile for the smooth and professional job.
