    New flooring and a Trench Drain in Elkridge, MD

    Here's a customer that with heavy rains his exising drain wasn't enough to stop water from coming in under his walkout basement door. This issue would cause his basement to flood to his old sump pump was. We installed a TrenchDrain outside the door with some WaterGuard XL as well as our Z Triplesafe 3. He so satisfied with our system, he decided to replace the existing flooring with our Elite Plank- Walnut flooring.

    This customer contacted us looking to waterproof her basement as well as upgrade her sump pump to a newer system with an airtight lid and a battery-powered backup. We chose to offer her the Supersump System. This system features the Zoeller M63 1/3 HP pump, capable of pumping 2,650 gallons per hour, a Waterwatch Alarm System that sounds off if the water rises above the point where the pump should turn on, the Superliner basin and an airtight lid. This system also features a CleanPump Stand, which serves to elevate the the pump from any silt or sediment that may build up at the bottom of the basin. For the battery backup we installed the Ultrasump 4, which features an automatic switching system to keep your basement dry in case of a power outage, main pump failure, tripped breaker or simply an unplugged main pump.

    To further waterproof her basement this customer also chose our Waterguard French Drain System and our Cleanspace Wall Liner, which is a 100% waterproof plastic barrier that helps guide any water seepage down to the drainage system.

    Customer would get water into the basement when the area would recive a heavy rain, could not pin point the location it would enter, would just see the aftermath and knew they needed the help of Basement Systems USA. 

    For this job we tracked down the area where the water was coming in and installed a ThermalDry Wall System which is a Vapor Barrier that has a radiant shield that reflects up to 97% of the heat back into your basement. We also installed Waterguard around the perimeter that will direct water getting in to the basement to the SuperSump Pump we installed as well, to get pumped out of the basement.

    We had previously done some waterproofing in this customers basement which included an install of a SuperSump Pump with Battery Backup and a SaniDry Sedona Dehumidifier. The customer reached out to us more recently because they were now ready to finish waterproofing the rest of their basement.

    To complete this waterproofing system we installed a Cleanspace Vapor Barrier for any water that is intruding through the finished wall, this barrier will direct the water down to the Waterguard that was installed and then over to the SuperSump to be pumped out and away from their home.

    Sandra R. of Baltimore, MD

    Customer Testimonial

              Basement Systems USA recently installed a Super Sump system and waterguard track in my basement and an outside underground sump pump drain pipe with ice guard and lawnscape outlet. The crew did an excellent job installing everything and cleaning the work area when finished. My only criticism was that, after installing the new discharge pipe, they didn;t cement over the hole they'd made in the concrete wall. I called the service dept and the manager said of course they'd fix that. I also asked if the outside drain pipe could be shortneed so the lawnscape outlet would drain better over the lawn. Again, he said yes because they wanted me to be satisfied. Mike Dyer was the technician who came to do the additional work, and I can't praise him enough. He d id a beautiful job of cementing over the hole in the basement wall-- you'd never know it was there. He shortened the outside drain pipe, refilled & tamped down the trench, and then went the extra step of obtaining & installing a popup outlet that works better in my yard. Mike also installed an 8' chute on the downspout to drain water away from my patio. Basement Systems did not charge me for any additional work. They mean it when they say they want their customers to be happy. I would recomment them without hesitation.

Affordable, Certified Waterproofers for greater Baltimore, Philadelphia, West Chester, and Lancaster

Basement water problems are as old as the structures themselves. Water will leak into a basement through any opening it can, including your walls, floors, and the joints between them. Water can even pass through the concrete itself -- which is one reason why basements are notoriously damp, humid spaces.

Other companies might try to sell you on inferior basement waterproofing solutions. Our products have been developed, patented, and perfected by Basement Systems®, Inc. -- the world's largest network of basement waterproofing contractors.

Whether you live in Philadelphia, Baltimore, Ellicott City, Wilmington, Upper Darby, Parkville or Lancaster, our basement experts will show you how we can customize your waterproofing solution to keep the basement dry all the time!

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
