Common Causes of Basement Leaks

After a storm, the ground around the foundation becomes loaded with rainwater. If your drains are clogged or broken, this water will sit there, exerting enormous pressure against your basement walls, until it naturally finds its way out. After a while, the pressure is relieved, but every time this happens, your walls become more damaged and vulnerable, eventually giving in and allowing water to seep in through cracks and joints.

In order to prevent new leaks and flooding in your basement, an effective drainage system must be in place. This way, water gets diverted from the soil around your foundation. By having a sump pump system added to your waterproofing system, your basement will be covered by an extra layer of protection.

French Drains
(the old-fashioned solution)

For a long time, French drains, also known as footing drains, have been the builder’s choice for groundwater control. They are installed around the external perimeter of the house, by the footing. This kind of drain tends to clog due to silt, mud and debris entering it, carried along with the water. This renders the drain ineffective, allowing water to build up and leak into the house. To fix a clogged drain pipe, it would be necessary to dig up the foundation all the way to the footing level.

Interior Perimeter Drainage Systems

At Maryland Mold and Waterproofing, we provide a superior alternative to the French drain. Our drainage system of choice is installed along the interior perimeter of your basement. This way, much less dirt is allowed to enter the pipes, which means no clogging. Internal drains are also much easier to service and repair, because no digging up is necessary to access them. We offer two types of drains, each suited to different levels of water diversion.

The GrateDrain™ is the standard drainage solution for basement water. It covers the water diversion needs for most basement.



The GrateTrench™ is even more powerful than the GrateDrain™, thus being more suited for larger volumes of water.

Sump Pumps

The sump pump is the core of any effective waterproofing system. Water collected by the drain pipes is channeled into the sump pit. Once there, the sump pump takes care of pumping it out of your basement and discharging it into the sewage system.

Battery Backup Sump Pumps

Sump pumps need electricity to operate. On the occasion of a power cut, your sump pump won’t be able to run, unless you have installed a battery backup. The backups provided by Maryland Mold and Waterproofing kick in automatically when power goes out, and recharge by themselves once power is restored. This level of autonomy in a waterproofing system means a lot less to worry about, during a heavy rainstorm.

Grate Sump Plus

The Grate Sump Plus™ is the standard battery backup system to sump pumps provided by Maryland Mold and Waterproofing. It activates by itself as needed and automatically recharges when the power is restored.

This system provides enough power for one pump to move up to 10,000 gallons of water. It also comes with a low battery alarm and LED indicator, to let you know in advance when more power is needed.

Grate Sump Plus II

Our Grate Sump Plus II™ is the definitive solution for water infiltration in your basement.

This system is comprised of two pumps, rather than one. It can handle virtually any volume of water, and keep your basement safe during extended power cuts.

Like all of our products, the Grate Sump Plus II™ is also backed by our Healthy Basement Certificate with a limited Transferable Lifetime Warranty!

We used Maryland Mold and Waterproofing to remediate mold from our HVAC system and to water proof our basement. That meant coordinating an HVAC company as well as the waterproofing done by Maryland Mold and Waterproofing. Colin Hall was our representative and coordinated this beautifully. He was not only very professional but made sure the job was done to our satisfaction and even came out himself to put our basement shelving back together when the job was complete. He takes pride in his work and made sure we were well taken care of. We finally have a dry basement after years of rain water infiltration. I highly recommend Maryland Mold and Waterproofing and hope you have a similar experience.

Maryland Mold and Waterproofing did a great job at performing mold remediation and crawlspace encapsulation on my house. I was pleased with all aspects of the process, from the initial estimate to project completion. I solicited estimates from three companies, including two national enterprises that advertise heavily. One never bothered to respond. The other sent someone to provide an estimate who was supposed to be a structural engineer (at least that was claimed in the company’s brochure), but had no such credentials on his business card. I had some concerns about possible structural problems, and the rep told me I needed a support beam and four jacks to buttress a “seriously under-engineered” floor. Subsequent attempts to follow up with that company met with no response. I decided to contract with Maryland Mold and Waterproofing and part of the contract included having an independent structural engineer evaluate the space. His evaluation concluded that there were no serious structural issues, just normal settling for a house that is 50 years old. The first MMW crew came out to remove all the moldy insulation and applied a fungicide in the crawlspace. Within a matter of days a chronic problem I have had with my sinuses that I thought I was stuck with for the rest of my life cleared up. A few weeks later a crew came to finish the encapsulation and install a dehumidifier. Both crews worked hard and efficiently in a very confined space and were courteous. I recommended the company to my neighbors, and MMW is doing the work on two more houses on my block.

Nick did a fine job of explaining our project and his team was here on schedule and did quality work with no problems. They treated the mold, encapsulated the crawl space and installed a dehumidifier and a turtl access hatch. Excellent work.

Great experience MD Mold and Waterproofing. The entire team was professional, responsive, knowledgeable, and did their jobs well. We have gone through a complete remodel of the old home we just purchased and have dealt with a million trades and contractors. The team from MD Mold and Waterproofing rose to the top! We'd highly recommend using them. Hats off to you, Nick and Colin, Freddy and the other gentleman who have made our basement water-free :-)

After our drain broke we discovered mold under the floor. Maryland Mold and Waterproofing provided a quote and was able to respond quickly after our agreement was signed. The folks were professional and courteous. Their efforts were much appreciated. They are definitely a company to consider if one has a potential mold issue.
