Elevator Pit Waterproofing & Concrete Protection | Prevent Leaks & Corrosion

The Problem: Water Infiltration & Corrosion in Elevator Pits

Elevator pits are highly susceptible to water leaks, corrosion, and concrete deterioration, caused by groundwater intrusion, hydrostatic pressure, and chemical exposure. If left untreated, these factors can lead to structural damage, electrical hazards, and costly repairs.

The Solution: Surtreat’s Elevator Pit Waterproofing System

Surtreat provides a multi-step sealing and reinforcement system to eliminate water leaks, strengthen concrete, and prevent long-term deterioration:

SurCoClean: Removes contaminants, oils, and dirt from the concrete surface.
SurCoExpel: Extracts deep-seated moisture and contaminants from the concrete matrix.
TPS II: Strengthens concrete by increasing density and reducing permeability.
Curtain Grouting: Creates a watertight polyurethane barrier against groundwater infiltration.
Self-Leveling Cement: Restores a smooth, even surface.
Waterproofing Cement: Provides long-term protection against moisture and chemical exposure.

Application Process: How to Waterproof & Protect Elevator Pits

Step 1: Surface Cleaning with SurCoClean
- Apply SurCoClean to remove contaminants, ensuring a clean surface.
- Pressure wash or scrub the surface for deep penetration and dirt removal.

Step 2: Extract Moisture & Contaminants with SurCoExpel
- Apply SurCoExpel to draw out deep-seated moisture and contaminants.
- Allow proper drying time before proceeding with additional treatments.

Step 3: Strengthen Concrete with TPS II
- Apply TPS II to densify concrete, reducing porosity and improving compressive strength.
- Ensures long-term durability and moisture resistance.

Step 4: Waterproof with Curtain Grouting
- Inject polyurethane curtain grouting through drilled ports to create a watertight seal.
- Expands and fills voids, preventing further groundwater intrusion.

Step 5: Structural Leveling with Self-Leveling Cement
- Pour self-leveling cement to restore an even, stable base.
- Ensures smooth placement for elevator components.

Step 6: Final Sealing with Waterproofing Cement
- Apply waterproofing cement to all treated surfaces.
- Forms a durable, chemical-resistant barrier to prevent future leaks and deterioration.
