Manhole Repair & Waterproofing
We use a less intrusive repair method that does not require excavation,
which minimizes restoration costs.
Our specialized industrial-strength materials have been rated
to the MTO standards to last for 25 years.
Concrete surface is completely restored thanks to monolithic adhesion provided by our materials.
Water infiltrating from the environment into a manhole puts an additional strain on sewage capacity. By sealing riser joints and cracks, we eliminate this issue.
Eliminate Leaks in Pre-Cast Structures
We inject riser joints between pre-cast manhole structures and repair cracks to eliminate leaking.
Eliminate Leaks in Cast-in-Place Structures
We inject joints in cast-in-place manhole structures and repair cracks to eliminate leaking.
Joint Seal Waterproofing provides manhole waterproofing in Toronto, Mississauga and all of GTA. We specialize in manhole repair and restoration.
We have done city projects ranging from maintenance chamber rehabilitation to their complete coverage.In some cases, concrete repair and waterproofing of the exposed shaft was required. Patch work, concrete restoration, crack injection and outer shell waterproofing applications were done.
We have also been able to cover manhole chambers because our specialized materials do allow for adhesion between metal and concrete.
Riser joint injection is another service we provide. Our specialized liquid rubber material ensures long-lasting results.
Riser joints are a weaker area in a concrete surface, where most leaking occurs. We inject them to stop leakage and provide long-lasting waterproofing.
Crack Repair & Patching
Cracks are repaired with specialized materials that ensure durable manhole repair and waterproofing. We can reprofile benching. Where necessary, patches as thin as 5 mm are applied.
Traditionally speaking, two slabs of concrete cannot be fused together when there is a crack. This, however, is not the case through the use of our specialized materials which make monolithic 1.85 MPa adhesion possible. Not only can we repair concrete but also restore it to its original condition, even when wet. It works both on single cracks and concrete surfaces with multiple issues - no need for complete resurfacing. Such rehabilitation is even done on concrete surfaces that are combined with metal structures.
Under traditional repair methods, patching requires a minimum of two-inch demolition in the affected area. The use of our unique products, Polyforce Plus, and polymer cement, permits thin-patch applications, making adhesion possible even between metal and concrete. The whole job is much more cost-efficient and faster.
Root & Incrustation Removal
Tree roots and incrustation are one of the causes of manhole leakage. We remove any type of incrustation and repair the damaged manhole walls by following our specialized crack repair and patching methods.
Parging & Coating
Once the manhole walls are patched, their surface is parged and coated with chemical-resistant membrane, which ensures long-lasting concrete waterproofing.
Steps and/or ladders are replaced if needed.
