This family in North Stonington, CT was tired of having a dirty basement that often leaked and flooded with water. They wanted a space that was comfortable and inviting, so they gave us at Connecituct Basement Systems a call, and we were happy to come out!

Taz Petersen, our System Design Specialist, quickly came up with a solution that would best suit this family's basement. Kryz Wilk and his team came out, and got ready to take on the task at hand. They first installed WaterGuard around the perimeter of the basement, which paired wonderfully with our SuperSump. These two products work together to create a first class drainage system for any basements. We also encapsulated the entire space with our bright and durable Cleanspace Wall System. This not only makes your space look brighter and cleaner, it also works to keep vapor and moisture out of the basement! 

This family felt much better about using their basement for all of their storage needs! Give us a call TODAY for your no cost estimate!

I would like to redirect discharge pipes to backyard and replace sump pumps. I have the perimeter system already in place. But The company I used to install the perimeter drainage system is not responsive anymore to my needs. Thank you
Project Location: North Stonington, CT
I am currently under contract with a home that has bad piers under the crawl space of the addition of the home. The cmu block on the outside has some missing mortar and gaps. One you can see and it looks like there is no concrete in the block or rebar.

Hi, I have a perimeter drain system with triple sump pumps from another company. I would like to redirect the discharge to go to my back yard instead of the front yard which is where it goes now. I was wondering if it's something you could do. The other company is not getting back to me and hasn't for awhile now.
