Comprehensive Waterproofing Solutions for Every Property Type

Water Basement Waterproofing Solutions problems never resolve themselves—they only grow worse with time. That’s why we provide a full range of interior and exterior waterproofing services designed to both stop current leaks and prevent new ones from forming.

1. Interior Basement Waterproofing

Interior waterproofing is a powerful and cost-effective way to control water that enters or accumulates around the foundation.

Our interior services include:

• Interior French Drain Systems: Installed along the basement perimeter to redirect water into a controlled drainage channel.

• Sump Pump Installation & Backups: High-capacity pumps with battery or water-powered backups ensure 24/7 protection.

• Vapor Barriers & Wall Encapsulation: Creates a moisture-resistant shield to prevent dampness, odors, and mold.

• Crack Sealing & Injection Systems: Epoxy and polyurethane injections stop leaks and reinforce weak points.

These solutions work together to create a reliable water management system that keeps interiors dry year-round.

2. Exterior Basement Waterproofing

For properties experiencing significant water pressure or long-term water intrusion, exterior solutions provide the most comprehensive defense.

Exterior waterproofing options include:

• Foundation Excavation & Waterproof Membranes: A permanent barrier installed directly on foundation walls.

• Exterior French Drains: Collects groundwater and redirects it away from the structure.

• Grading & Soil Recontouring: Ensures proper water flow away from the foundation.

• Downspout Extensions & Surface Drainage Systems: Reduces roof runoff from pooling near the building.

Exterior waterproofing addresses problems at their source, stopping water before it ever reaches the basement walls.

3. Foundation Repair & Structural Stabilization

Foundation issues are common in Greenwich—especially in older properties or buildings constructed on shifting soil. Even minor cracks can indicate deeper structural concerns.

We provide:

• Epoxy Injection for Structural Cracks

• Polyurethane Injection for Active Leaks

• Carbon Fiber Reinforcement for Bowing Walls

• Steel I-Beams for Advanced Structural Support

• Settlement Correction with Helical or Push Piers

These repairs restore strength, stability, and long-term structural integrity to your home or commercial space.

4. Moisture Control & Mold Prevention

Waterproofing isn’t just about stopping leaks—it’s also about preventing long-term moisture damage.

Our moisture control systems include:

• High-efficiency dehumidifiers

• Crawl space encapsulation

• Mold-resistant coatings

• Air circulation and humidity management solutions

These services help maintain a healthy indoor environment and protect valuable property materials from moisture-related deterioration.
