Elevator Pit Waterproofing From the Inside
- Elevator pits waterproofing & repairs
- Re-sloping
- Sump pump / back up installation
- Press pits waterproofing & repairs
The solution for a more economical alternative is to work from the inside with negative waterproofing, designed specifically to waterproof mineral substrates like masonry and concrete from the inside (negative side) by reacting to the moisture in the wall as well as the components of the substrate to produce crystals that block the pores.
Crystalline penetrates into the substrate and becomes an integral part of the wall that blocks water transmission while remaining open to vapour diffusion, and it will not detach from the substrate.
The Issue
- Water leaking from cracks, tie rod points, piping and flooring
- High water tables, negative pressure on concrete substrate, failing or missing joints
Our Solution
- Negative side waterproofing
- Crystalline crack and patch repair, repairing existing and new structures
- Wall & floor cracks and patches
- Concrete rehabilitation
- Sump pump & trenching
Advantages
- Environmentally sound and certified
- Suited for all mineral substrates
- Becomes an integral part of the structure
- Resistant to sulfates and chlorides
- Self-healing properties on micro-cracks
- Resistant to freeze and thaw cycles
Frequently Asked Questions
What is negative side waterproofing?
It is waterproofing applied from the inside (negative side) of a concrete or masonry structure. The crystalline material reacts with moisture in the wall and with the components of the substrate to produce crystals that block the pores, without the cost and disruption of exterior excavation.
Will the crystalline treatment detach from the wall?
No. Crystalline penetrates into the substrate and becomes an integral part of the wall, blocking water transmission while remaining open to vapour diffusion, so it will not detach from the substrate.
