Before and After Pictures from New London

The B. Family had a crack in their basement that was a real pain. Every time it rained, water would come into the basement, and anytime it snowed, the snow would eventually melt and water would come in. The homeowners called the experts at Connecticut Basement Systems to make sure the issues was taken care of. We came in and diagnosed the problem and recommended our FlexiSpan® crack repair system. 

The FlexiSpan® is unlike hydraulic cements and some epoxies: the special polyurethane polymer sealant used for FlexiSpan® will never dry out or re-crack even given the natural movement of the foundation wall over long periods of time. The homeowners can now rest assured that the basement will not take on water from that crack.

This New London basement had reoccurring water issues that were making the area unusable. The constant water would leave a musty odor and the clean-up process was beyond frustrating for the homeowner. She wanted a solution to solve the constant water problem and to get rid of the distressing smell. The homeowner decided to call Connecticut Basement Systems for a free home estimate. 

The solution for this basement was to install a WaterGuard System. This system is installed internally around the perimeter of the walls and then is concealed with cement. (You can see the wet cement in the after photo.) The WaterGuard System will collect water internally and channel it out to the sump pump. The sump pump will then take the water and disperse it through the discharge line. A CleanSpace liner is beneficial for this basement because it acts as a moisture barrier which will prevent any water from seeping through the walls. (You can see the CleanSpace Liner on the walls in the after photo)

Once the installation was finished, the basement was waterproofed and the musty odor was eliminated. This is exactly what the homeowner wanted and could not be happier with the results.

Waterproofing in New London CT

Wet spots in a basement are always a sign of concern and, when Susie D. found them in her basement, she knew that towels would help only so much.  Susie began researching companies and found Connecticut Basement Systems soon after.  She then met with waterproofing specialist Michael Lane, who had a solution to her water spot problem.

With Michael’s guidance, Luis and his crew came in and installed a Trench Drain and WaterGuard combo to ensure the current water would drain effectively out of her basement.  A SuperSump sump pump was also installed to ensure future flooding would be a problem of the past.  Finally a SaniDry Dehumidfier was installed to eliminate all future threat of excess moisture in the basement.

With Susie’s basement taken care of, Susie knows that the experts at Basement Systems know what they are doing and will hopefully continue to use their expertise for any of her future house problems!
