Basement water intrusion and foundation issues are two of the most serious problems homeowners and commercial property owners face in Greenwich, CT. With the area’s coastal climate, heavy seasonal rainfall, and diverse soil conditions, building foundations are constantly exposed to moisture, shifting soil, and hydrostatic pressure. Without proper protection, these conditions can lead to basement flooding, mold growth, structural instability, and costly long-term damage.

Our team specializes in delivering permanent basement waterproofing and foundation repair solutions designed to protect your property year-round. Whether you’re dealing with persistent leaks, structural cracks, bowing walls, or moisture-related problems, we provide durable, high-quality services tailored to the unique conditions of Greenwich, CT.

Why Permanent Protection Matters

Waterproofing and foundation repair are not one-time fixes—they are long-term investments in the safety, value, and longevity of your property. Problems such as water seepage, cracked foundations, or damp basements never go away on their own. In fact, they worsen over time, leading to:

• Mold and mildew growth

• Damaged flooring, drywall, and insulation

• Wood rot and corrosion of structural components

• Decreased indoor air quality

• Foundation settlement or wall bowing

• Reduced property value

Permanent solutions ensure that your basement stays dry and your foundation remains stable regardless of weather conditions or aging structures.

Comprehensive Basement Waterproofing Services

We provide complete waterproofing systems that eliminate existing water problems and prevent new ones from developing.

1. Interior Basement Waterproofing

Interior waterproofing is a highly effective way to manage water intrusion and control moisture inside your basement. It is especially beneficial for older Greenwich homes and commercial buildings with existing water issues.

Interior Drainage Systems

We install interior French drains along the perimeter of the basement to collect and redirect water. This system captures groundwater before it reaches your living space.

Sump Pump & Backup Systems

Our high-performance sump pumps, combined with battery backup units, ensure your basement stays dry even during intense storms or power outages.

Vapor Barriers & Wall Encapsulation

Heavy-duty vapor barriers prevent moisture penetration through foundation walls, reduce humidity, and create a clean, finished look.

Crack Sealing & Injection

For minor leaks, we use epoxy or polyurethane injections to permanently seal foundation cracks from the inside.

2. Exterior Basement Waterproofing

Exterior waterproofing is the most comprehensive method for preventing water from entering your property. This service is ideal for buildings with recurring water intrusion or significant hydrostatic pressure.

Foundation Excavation & Waterproof Membranes

We excavate around the foundation, repair any structural concerns, and apply premium waterproof coatings and membranes designed to last for decades.

Exterior French Drains

These drains divert groundwater away from your structure, lowering hydrostatic pressure and preventing leaks at their source.

Grading & Drainage Improvements

Proper soil grading ensures water naturally flows away from your home. We also install downspout extensions and surface drainage systems to improve exterior water management.

Permanent Foundation Repair Solutions

Foundation damage requires immediate attention to prevent serious structural problems. Our experts specialize in long-lasting and structurally sound repair solutions.

1. Foundation Crack Repair

Foundation cracks are common in Greenwich due to soil conditions and seasonal changes. We provide:

Epoxy Injection

An ideal solution for structural cracks, epoxy bonds the concrete back together to restore strength.

Polyurethane Injection

A flexible, expanding sealant that permanently stops active leaks and water infiltration.

2. Wall Reinforcement & Stabilization

Carbon Fiber Reinforcement

For bowing or leaning walls, carbon fiber straps provide high-strength stabilization without major construction.

Steel I-Beams

When walls require more robust support, steel beams offer long-term strength and prevent further movement.

3. Foundation Settlement Repair

Uneven floors, sticking doors, and exterior cracks are all signs of foundation settling. We offer:

Helical Piers

These steel piers anchor your foundation to stable soil, lifting and stabilizing it permanently.

Push Piers

Used for heavier structures, push piers correct settlement and provide long-term stability.

Moisture Control & Mold Prevention

Permanent basement waterproofing is not just about stopping leaks—it’s also about creating a healthier indoor environment.

We provide:

• High-capacity dehumidifiers

• Mold-resistant coatings

• Air quality treatments

• Crawl space encapsulation

These solutions prevent mold growth, improve indoor air quality, and protect your property from moisture-related damage.
