Basement Waterproofing in New London County, CT

We install a system below the basement floor that drains groundwater from cold joint seepage and rising water beneath the slab. It leads to a sump pump, which moves water safely outside—no maintenance, no recurring service needed.

Common basement problems we eliminate:

• Leaking at the floor or wall seam: typical cold joint failure
• Persistent musty smell: a sign of trapped basement moisture
• Surface water after storms: caused by hydrostatic pressure
• Water-damaged belongings or flooring: often recurring

Our SuperCrete Crawl Space System creates a smooth, sealed concrete layer across your entire crawl space. It stops rising moisture, makes utility access easy, and eliminates the need for vapor barriers or dehumidifiers.

Issues we solve under your home:

• Moisture and mildew from the ground: impacts air quality
• Sagging insulation and framing: caused by excess humidity
• Rodents and insects: attracted to dark, damp spaces
• Lost storage potential: due to unsealed dirt floors

We install high-performance sump pump stations with cast-iron pumps, sealed basins, silent check valves, and optional Wi-Fi backup protection. Designed to handle storms and outages—no matter the season.

Frequent sump pump problems we prevent:

• Frozen or clogged discharge pipes: common in winter
• Failure during heavy rain: due to poor design or cheap parts
• Flooding during power loss: no backup in place
• Noisy or vibrating pumps: signs of incorrect installation
