Before After
SunHouse Window Well Enclosure in Berlin, CT SunHouse Window Well Enclosure in Berlin, CT

This old basement window well was rusty and corroded. Water would collect inside it when it rained, and then leak into the basement through the window. We took out the old well and replaced it with our SunHouse window well enclosure. The clear cover and brightly colored sides of the SunHouse maximize the sunlight directed into your basement for a brighter, more attractive space. Meanwhile, the plastic cover keeps out dirt, debris, and water. The owners of this home can enjoy their basement more now that it's filled with bright natural light, and don't have to worry about water!

When we arrived in this basement, it was a wet space. The moisture in the air was causing problems with rot and mold. While it's possible to remove mold, it will come back unless the basement is dry. To help with this, we installed the TripleSafe sump pump system. A sump pump in an integral part of a waterproofing system, as it rids the basement of any water that collects there. Our TripleSafe is the best choice for a sump pump; it includes an airtight lid, primary pump, secondary pump, and battery backup sump pump. This basement will remain dry for a long time, thanks to our products!

Job Stories From Berlin, CT
DryTrak System in Berlin, CT

This Berlin, CT home had a water problem in the basement. This concerned the homeowner who wanted a dry basement all the time. She was concerned that she would not be able to find the perfect solution since she had monolithic concrete floors in her basement. After seeing an ad of Connecticut Basement Systems in the newspaper and doing some research, she decided to trusts the experts and help provide her a solution. 

On the day of the appointment, Sales Representative Anthony Martingano arrived at the home to inspect the basement. He reassured the homeowner that we had the perfect solution for her wet basement. Our patented DryTrak system was specifically designed for basements that have monolithic concrete floors. The advantages to the DryTrak System are:

  • No jackhammering during installation
  • Collects water from walls and floor joint
  • It is installed above the mud zone to prevent clogging
  • Includes a written lifetime warranty

Anthony explained that the DryTrak Drain Pipe System provides a simple, common-sense solution to help avoid a messy and time-consuming installation. This is the solution that the homeowner was looking for and decided to follow through the project.

On the day of the appointment, Foreman Krzys Wilk and his team installed the DryTrak system and a TripleSafe sump pump professionally and efficiently. The DryTrak system essentially captures water before it enters the basement and leads it to the TripleSafe sump pump. From the sump pump, it is discharged away from the home. 

Once the project was completed, the homeowner experienced a dry basement all year around and was very pleased with the results.  

FlexiSpan in Berlin, CT

These Berlin homeowners had a crack in their basement wall that would allow a lot of air and moisture to travel through. Thus, making the basement a wet and unappealing area of the home. Already working with Connecticut Basement Systems having a finished basement, they decided to work again. 

The solution for this problem was to install our FlexiSpan product. FlexiSpan will prevent leakage through the crack thanks to its 3 step process. The first step is to apply a flexible sealant along the full length of the crack. Next, a strip of porous foam is installed over the crack. Lastly, an impermeable membrane is attached to the wall on both sides of the foam strip. This will direct any water leakage to the waterproofing system. This is exactly what the homeowners wanted and were happy that they chose to work with us again!

During heavy rains we get water coming in our basement near the hatchway
Project Location: Berlin, CT
House built in 1900 with stone foundation and poured concrete floor at the base of a drumlin. After significant rain, groundwater perches on glacial hardpan and seeps in through crack between wall/floor, columns in floor, and through some areas in the stone wall itself in extreme cases. Poured concrete floor has many low points where water pools. There is a sump pump, but there is a significant lip in the poured concrete, so water only reaches it when it is almost 1" deep.
Project Location: Berlin, CT
I have new construction house with an 8' basement. At the time we poured the slab we had no water. I have interior footing drains going to sump pit but the water table has risen drastically since pouring the slab and I'm getting water overflowing the sump pit. I have limited options on where to pump the water and I need expertise on what to do from here. The house is framed and the expected finish date is July.
