Job Stories From Plymouth, CT
Waterproofing Installation in Plymouth, CT

This Plymouth, CT home was lacking a waterproofing method, and that was beginning to worry the family that resided in it. They decided to call Connecticut Basement Systems to perform the job they needed done!

First, to guide the water out of the home, we installed our WaterGuard below floor drain. The WaterGuard is installed in a bed of gravel on top of the foundation footing which keeps it out of the "mud zone". We then installed our TrenchDrain system at the basement entrance, so any water flowing in from the stairs would drain immediately. Finally, we installed our SuperSump sump pump system, so that any potential water getting into the room would drain immediately. 

This family can now feel safer in their home, and know they'll have a full-proof waterproofing method for years to come! Call us TODAY for your FREE estimate!
