When it comes to safeguarding your home or commercial property in Greenwich, CT, nothing is more important than a solid, watertight foundation. Water may seem harmless at first, but even minor seepage can snowball into costly structural issues, mold growth, air quality problems, and long-term property damage. That is why choosing trusted, permanent basement waterproofing experts is essential. Our team specializes in both interior and exterior waterproofing systems designed to fully protect your home from every possible angle—ensuring long-term durability, safety, and complete peace of mind.
Why Permanent Waterproofing Matters in Greenwich, CT
Greenwich is known for its beautiful homes, rolling landscapes, and coastal climate—yet these same features can also create the perfect conditions for water intrusion. Heavy rainfall, fluctuating groundwater pressure, older foundation designs, and seasonal storms all put additional stress on your basement walls and floors. That’s why temporary fixes like patchwork sealants or DIY repair kits simply aren’t enough.
A permanent waterproofing solution addresses the root cause of water intrusion, not just the symptoms. By combining interior and exterior systems, you get full structural protection that stands up to hydrostatic pressure, soil expansion, drainage issues, and long-term moisture exposure.
Exterior Basement Waterproofing: The First Line of Defense
Exterior waterproofing is considered the most proactive and comprehensive method of keeping water out of your basement. Our exterior systems focus on stopping water before it ever reaches your foundation walls. This process typically includes:
Full foundation excavation to expose the exterior wall
Crack repair and foundation sealing using premium-grade waterproof membranes
Exterior drainage system installation such as French drains or perforated drain tiles
Soil grading and re-backfilling to improve runoff
Installation of protective barriers to divert groundwater away
This method provides a powerful shield around your home’s foundation, ideal for properties with chronic water problems, landscaping issues, or high water tables. Exterior waterproofing, when done professionally, can last for decades—often the lifetime of the structure.
Interior Basement Waterproofing Systems: Guaranteed Dry Protection
While exterior waterproofing tackles water at the source, interior waterproofing manages moisture that has already reached or is trying to penetrate the inside of your basement walls or floors. Our interior systems are designed for precision, performance, and long-lasting results. They can include:
Interior French drains and drainage channels
Basement sump pump systems with battery backups
Foundation crack injection and structural reinforcement
Interior wall coatings or sealants
Vapor barriers to block moisture and humidity
Dehumidification systems for air quality control
Interior waterproofing is ideal for finished basements, homes without exterior access, and properties where water infiltration occurs through cracks, porous walls, or floor seams. It is also cost-effective and minimally invasive compared to exterior excavation.
