Water intrusion is a big threat to the safety and durability of below-grade structures. From tunnels and basements to retaining walls, underground construction projects face moisture issues. In these situations, conventional waterproofing techniques are highly effective. Blindside waterproofing is the right choice when the structure’s exterior side is inaccessible after construction. It develops a protective waterproof barrier before pouring the concrete. Let us discuss when to use the blindside waterproofing solution.
Different scenarios of using blindside waterproofing
There is no need for blindside waterproofing for every project. However, it is essential in some construction conditions where you have limited external access.
Inaccessible exterior walls
When workers cannot access the exterior surface of the foundation wall after a construction project. It occurs in deep excavation sites, property line constructions, and urban developments with limited space.
In this case, blindside systems ensure protection before placing concrete.
Deep basement construction
Modern residential and commercial buildings include underground basement levels for storage and parking. Deep basements are exposed to soil moisture and groundwater seepage.
Blindside waterproofing Toronto is the right choice for these applications. It secures the structure from water intrusion in high-pressure underground environments.
Higher water table areas
Many projects are conducted in high groundwater levels experience leaks. So, you may use blindside waterproofing in various scenarios-
- The soil, retaining moisture
- Seasonal flooding
- Groundwater surrounding the structure
- Water pressure against your basement walls
A well-installed blindside membrane reduces the risk of water seepage, concrete deterioration, and mold growth.
For underground infrastructure and tunnels–
Underground structures like tunnels and subway systems depend on blindside waterproofing. The excavation systems prevent access to the exterior structural walls.
These environments need strong waterproofing systems that manage continuous moisture exposure.
Long-term structural protection
Water damage reduces a building’s lifespan. In due course, moisture infiltration causes cracks in concrete. The steel components will also show signs of corrosion. Blindside waterproofing is a continuous barrier that reduces maintenance costs.
Conclusion
Blindside waterproofing is a solution for below-grade structures that restrict exterior waterproofing access. To construct deep basements or tunnels, you may choose this waterproofing solution.
