Waterproofing & Leak Sealing
What is Waterproofing & Leak Sealing?
Waterproofing and leak sealing prevent groundwater infiltration and structural deterioration by creating impermeable barriers in and around underground structures. Using trenchless polymer injection, this process blocks active leaks, seals joints and cracks, and protects critical infrastructure from long-term water damage.
Problems It Solves
- Groundwater infiltration through joints, cracks, or penetrations
- Structural deterioration caused by ongoing leaks
- Hydrostatic pressure threatening tunnels, vaults, or retaining walls
- Erosion and soil migration from uncontrolled water flow
- Costly maintenance and downtime due to recurring leaks
Types of Polymers Used
High-Density Polyurethane Foams
- Expands to stop active water leaks
- Bonds to wet or dry surfaces for reliable sealing
- Cures rapidly for fast water control
Structural Polyurethane Resins
- Creates rigid seals in cracks, joints, and voids
- Provides long-term reinforcement in structural elements
- Protects against future infiltration and deterioration
Hydro-Insensitive Polymers
- Expands and cures in flowing or saturated conditions
- Effective for sealing leaks in high groundwater environments
- Maintains durability under extreme water pressure
Benefits of Waterproofing & Leak Sealing
Waterproofing and leak sealing create reliable barriers that stop water infiltration and extend the service life of infrastructure. This trenchless method prevents erosion, protects structural integrity, and reduces long-term maintenance costs.
Long-Term Protection Against Water Intrusion
- Stops active leaks in wet or saturated conditions
- Protects infrastructure from water-related damage
- Non-invasive, trenchless installation process
- Provides durable sealing for long-term performance
