Long-Term Solutions for Conduit Waterproofing

More cable conduit waterproofing was done this week using the same method that has proven to be successful at projects done for a major fiber-optic internet company. Those jobs involved waterproofing internet cable conduits that were causing leaks into parking garages.


Characteristics of the Site

This project was done at an events salon on Lakeshore Rd. in Mississauga. There was leaking into the basement caused by seven conduits that penetrate the wall. Proper waterproofing had to be done to eliminate the issue.


Repair Method

As always, proper preparation is crucial for a successful waterproofing installation, as it requires sufficient adhesion. We thoroughly cleaned the substrate to ensure there was no humidity remaining in the area that had to be sealed. The surface was cleaned with solvents and coated with the first layer of a cold-applied polyurea-based membrane, followed by fiber glass, for durability. Another polyurea coat was applied next. This procedure was done both on the conduits and on the area of the wall adjacent to them, to ensure lasting results.


Benefits of Polyurea

Polyurea is a synthetic polymer created by reacting an isocyanate component with an amine blend. Its molecular structure is resistant to moisture, making it an excellent choice for a waterproofing membrane. Polyurea-based membranes are highly versatile and can be applied to both vertical and curved surfaces, making them ideal for complex architectural structures. They offer numerous advantages, including thermal stability, quick application, and the ability to adjust texture and thickness. Additionally, polyurea is an environmentally friendly product, as its solvent-free, 100% solids formula can be fully recycled.
