Why Do Connecticut Basements Get Wet?

Flooded basement: Connecticut has humid continental climate with seasonal extremes. With precipitation year round and heavy rainfall occurs during the summer thunderstorm season flooding is an issue. When flooding hits your area, your basement is most likely to be the prime target for water damage.

Other wet basement signs: There are many possible sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.

    Thank you for a job well done. The system works so well. 100 % of the water is now diverted and the pump has never even turned on. Since my system has been installed, we have had major rain storms, hurricane, October nor-easter and not a hint of moisture in the basement- I would recommend this system to anyone with a wet basement. Very satisfied customer, -Dr. Bryan Barry

    We had two installation in the past 4 months. While both crews kew what they were doing the later crew was outstanding. For one thing they used a table saw to cut the floor tiles which made the job quicker and neater. They were able to recitfy some of the issues left by the first crew. Secondly they were better able to communicated with me.
