The owners of this Coventry home called us when their wall crack started leaking again, despite previous attempts to seal it. Repairing leaky wall cracks can be tricky. If sealed with a rigid sealant, the wall movement that originally caused the crack will break the seal, creating the same problem over again. Our FlexiSpan is flexible enough to bend slightly and stays bonded despite wall movement, and seals the crack permanently.

This crawl space in Coventry, CT was dirty, cold and had a lot of moisture which was a concern to the homeowner. Wanting a solution for his crawl space, he called the experts at Connecticut Basement Systems and scheduled an appointment.

Our Sales Representative, Steve Godbout, arrived at the home on the day of the appointment and concluded that a CleanSpace Liner would be the perfect solution for this crawl space. A CleanSpace Liner prevents air and moisture from entering the crawl space. The benefit of air and moisture not entering the crawl space is that the floors in the home directly above will be noticeably warmer. The homeowner approved of this proposal and could not wait for his clean, dry crawl space.

On the day of production, Cisco and Josh installed the CleanSpace Liner efficiently and professionally. Not only does this liner protect against mold and moisture, but it also gives the crawl space a clean finish. This solution satisfied all of the homeowner’s needs and could not be happier thanks to Connecticut Basement Systems!

Garage door thresholds and the base of the foundation wall between them are chipping away. This is likely due to a improperly graded driveway that allowed water into the garage and against the foundation during moderate/heavy rain. The grading issue will be corrected when the driveway is replaced this season.

This is my first basement flood in 31 years of living in a home I was involved personally in building. I'm looking for negative side waterproofing. I am concerned about mechanicals and how you deal with them when they are along the walls? And will a high water table impact your work?
