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 interior drains, each suited to a different part of your basement.

Interior Perimeter Drain System

Our Interior Perimeter Drain System is the standard drainage solution for basement water: an enclosed drain channel set below the slab at the footing and piped to the sump, with corner clean outs and a Limited Lifetime Warranty.

Interior Trench Drain

Our Interior Trench Drain carries water past stairs, equipment, or walls that block the perimeter drain, and ties into the interior system.

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.

Sealed Sump Pump System

Our Sealed Sump Pump System pairs a cast iron pump with a deep sealed liner, a gasket, and a radon-ready lid.

Primary & Battery Backup Sump Pump System

Our Primary & Battery Backup Sump Pump System pairs a 2,770 GPH primary pump with a 1,000 GPH backup pump and a 100Ah sealed battery, so your basement stays protected during extended power cuts. A new liner is optional.

My experience with Maryland Mold was excellent! From the initial walk-through with John, the written proposal to the installation of my dehumidifiers to help remove significant humidity from my basement was a thorough and detailed process with professional service. Maurice was my technician and his customer service was impeccable! I highly recommend Maryland Mold if you have any water intrusion, humidity or general basement needs or concerns.

We had some water in our basement after a hard rain. Nick was here the next day, identified the problem, and was able to refer us to the right person to get it fixed up. Fantastic service! I hope we don’t need them, but if we did I would call Maryland Mold and Waterproofing in a second!

I can’t recommend Nick enough. This is the place you should call when you have a foundation issue. His quote was 1/3 of the other quote we got but then he said that to be honest, the problem is probably clogged outlet drains and the water is backing up against the house. He suggested consulting with a landscaper first and addressing the problem, and then we may not need to do anything to the basement. We talked to our landscaper and he can replace the drain hoses/ down spout and direct the water away from the house. Nick, there is a special place in heaven for people like you!

I have had workmen who come and do a job with out acknowledging me, but both Kenney and Phil were very courteous hardworking as well as hospitable and kept me updated each step of the process as they worked. I must admit their decision making was greatly appreciated and it reflected in their work. For my next project I will request their services again.
