Our Services

Our Waterproofing Services Include

Exterior Waterproofing

Prevent Water from Entering Your Foundation

Exterior waterproofing is the most comprehensive long-term solution. It targets water intrusion before it ever reaches your basement.

Services Include:

  • Foundation Excavation: We dig around the perimeter to access and waterproof exterior foundation walls.

  • Exterior Membrane Application: A durable waterproof membrane is applied to foundation walls to block water entry.

  • Exterior French Drains: Subsurface drains are installed to redirect water away from the foundation.

  • Gutter Downspout Extensions & Grading Correction: Ensures that roof runoff is diverted safely away from the home’s base.

Interior Waterproofing

Control Moisture at the Source

Our interior waterproofing systems are ideal for basements already showing signs of water penetration. We contain and redirect water before it causes further damage.

Services Include:

  • Interior Drainage Systems (French Drains): Installed along the perimeter to collect and channel water to a sump pump.

  • Sump Pump Installation & Replacement: We install premium-grade pumps with battery backup options to ensure continuous operation during storms.

  • Wall & Floor Sealants: High-strength vapor barriers and waterproof coatings are applied to block moisture infiltration through porous surfaces.

  • Crack Injection & Sealing: We seal wall and floor cracks using professional-grade epoxy or polyurethane foam to stop active leaks.

Drainage & Water Management

Redirect Water. Protect the Structure.

Effective drainage is the foundation of any long-term waterproofing system. Our drainage and water management solutions are designed to control water flow above and below ground, ensuring it is directed safely away from your basement and foundation.

Services Include:

Interior French Drains: Installed along the interior perimeter of your basement to capture groundwater and redirect it to the sump pump for removal.

Exterior French Drains: Buried outside the foundation to intercept and redirect subsurface water before it reaches the structure.

Surface Drainage Systems: Channel drains, swales, and catch basins collect rainwater and runoff from driveways, patios, and lawns to prevent pooling near your home.

Gutter & Downspout Extensions: We reroute downspouts and install underground discharge lines to move roof runoff safely away from your foundation.

Grading & Re-sloping: We correct negative yard slope by regrading soil to guide surface water away from the building.
