Based in Ottawa, Bol-Dan Foundation & Masonry Inc’s team comprises foundation contractors certified to provide basement waterproofing services, which involves Platon® installation.

Basement Waterproofing in Ottawa

Out of all the areas on your property, your basement is the most prone to moisture and wetness development. If you want to avoid severe structural damage to your property, we can help you. At Bol-Dan Foundation & Masonry Inc, we provide basement waterproofing services in Ottawa to maintain the structural integrity of your home.


The soil under your basement often forces water and moisture through the cracks and openings in your basement floors. Internal water leaks, ineffective grading, defective gutters, drain tiles, and sump pits, and cracks in the foundation are some of the many causes behind basement moisture. The presence of this moisture can damage the foundations of your home and cause irreparable damage if ignored. It also encourages the growth of various bacteria and mould and can potentially harm your health.


We offer guaranteed waterproofing solutions using high-quality products, such as Platon® membranes. To learn more about our basement waterproofing service in Ottawa, get in touch with us today. We don’t just serve Ottawa but also offer our services in its surrounding areas.

Système Platon


Platon® is high-density polyethylene (HDPE) membrane. We install this on the basement floor and wrap your foundation walls. It prevents any moisture from the soil from entering your basement floor and walls and prevents the resulting damage. Here are some additional advantages:


  • The membrane’s double leakage protection makes it possible to hold humid soil away from the foundation wall and provides it with the drainage it needs to stay dry.
  • If your foundation walls are showing signs of wear, the membrane bridges cracks, keeping the water out even if the walls settle, crack or shift.
  • It is also versatile, as it works on just about any kind of wall, including poured concrete walls, block walls, wood walls, ICFs and existing foundations.
  • Platon® membrane is easily installed on your foundation walls. A special type of clip keeps it fastened to your foundations even in tough weather.
  • This membrane is environmentally friendly. The high-density polyethylene used in its fabrication comes from approximately 85% recycled material. In addition, none of its components will contaminate the soil or your home’s air.

How it Works

Our team of experienced professionals has been meeting the basement waterproofing needs of Ottawa homeowners for nearly 3 decades. Have a look at our detail-oriented process described below.

  • Excavation of the foundation: Our process begins with carrying out a thorough investigation of your drainage system, the foundation wall and footing, and checking for any signs of damage.
  • Fixing cracks in the foundation: We carry out the necessary repairs if we find cracks in the basement foundation or any other kind of damage. In many cases, a foundation might not require any repairs.
  • Installing footing flood boot: The area where your footing and foundation merge is exceptionally vulnerable to water damage. We add an aqua block membrane along with reinforcement protection.
  • Installing membrane: We then install the Platon® waterproof membrane in your basement. This high-quality, high-density polyethylene (HDPE) membrane keeps water out and protects your foundation from moisture damage.
  • Installing drainage tiles: Drainage tiles are an essential aspect of your waterproofing system. They work in tandem with the membrane to keep your basement water-resistant. We take care of your drainage system if required.
  • Carrying out grading: Grading is the final step in waterproofing your basement. The excavation surrounding your foundation is covered by our team, followed by the creation of a slope or grading around your property to keep water away.
  • Final assessment and cleanup: Once you have carried out the last step, we finish the waterproofing process by conducting a final inspection. Our team will ensure there is no damage to your property.

Why Do You Need Basement Waterproofing?

Your basement is a critical part of your home's foundation, which is why any damage to it potentially threatens your home's structure. Here are some reasons why waterproofing your basement is beneficial:


  • Prevents flooding - Basement flooding can seriously damage your home and your possessions. In some cases, the damage might be irreversible.
  • Prevents mould - The presence of mould and mildew can give rise to a host of health problems like allergies.
  • Prevents foundational damage - Moisture can creep into your basement floor's cracks and expand, worsening the damage in the process.
