About Basement Waterproofing

AQUEDUCT WATERPROOFING, LLC has been serving the entire Washington DC metropolitan area taking care of leaks and humidity problems in homes just like yours since 1987!  We will be able to provide you with a free consultation and estimate so that you can get a better idea as to how much the work is going to cost, and what exactly will be done to fix your wet basement problems for good.

On our site, you will be able to find out information about waterproofing your basement. Here, you can find out why you have leaks when it rains, why there is mold growing on your walls or floors, or why it is so important to be sure that all moisture problems are taken care of quickly before they lead to even more damage.

We use all of the most effective methods and products to take care of seepage problems.

 1. Leaky Basement Window Wells:  When the window well is clogged, water will push up against the basement windows until it breaks through the window seal.

2.  Foundation Wall Cracks: Wall cracks could be a sign of an underlying structural problem.  They must be filled and sealed before water starts to seep in.

3.  Efflorescence: This is typically a white, flaky, and chalky substance that can be seen on the basement walls or floors. It is a sign that moisture is present.

4.  Porous Concrete: Porous concrete has a unique appearance, and often falls apart in a honeycomb pattern. The problem is also sometimes referred to as spalled concrete. All terms refer to the same foundation problem. If left untreated for too long, moisture will begin to seep into the home. 

5. Cove Seepage: The cove joint in the basement is found where the wall meets the floor. This area can be extremely vulnerable to groundwater seepage. The soil around a foundation has constantly changing moisture levels. When it rains, it raises the water table. When there are dry spells, the water level goes down. However, the rising and falling of these moisture levels can put a significant amount of pressure on your foundation walls. Eventually, water pressure from the soil will break through the seal in your cove joint.  Once inside, the moisture can do a lot of harm to the basement environment. 

6. Floor Drains: Floor drains are often installed in the lowest-lying area of a basement. The purpose of the drain is to prevent water from flooding this area of the home. If the basement leaks the water should be sent out through the drain before it is ever able to puddle up on the floor. However, these drains are not the best "waterproofing" system to have installed in a home, and they often times fall short when it comes to preventing serious moisture problems. 

7. Wet Floor Cracks: Floor cracks will eventually let water to seep into the home when the water table outside the foundation rises or falls. 

8. Mold & Mildew: Mold grows in wet and humid areas, such as in a basement with no waterproofing system, or in a basement or kitchen where there is a lot of moisture. 

9. Sump Pump: A sump pump's primary job is to keep buildings dry, so they're typically installed in the lowest part of a home's basement or crawl space, and are designed to discharge water away from sanitary sewers.  

10. Leaking Mortar Joint:  Leaking mortar joints become weak over time and will start to let water leak into the home. 

11. Pipe Penetration: The area where the pipe leaves the home through the wall may have a weak seal and will allow water seepage. 

12. Grading Problems: Poor yard grading and drainage can cause water to pool up next to the foundation walls. 

13. Top of Foundation: Water seeping in over the top of the foundation wall will leave a trail of water stains down the foundation wall.

About Foundation Repair

AQUEDUCT WATERPROOFING, LLC - has nearly 30 years diagnosing and repairing the problems associated with foundation cracks.  We repair everything in a foundation from a simple crack to a full wall.  We use The Reinforcer Carbon Fiber Wall Reinforcement System, manufactured by Nash Distribution.  The Reinforcer is a foundation wall repair product that has been proven effective at taking care of a variety of foundation problems.

Cracks in the walls of your foundation may be caused by the normal shrinking and curing of concrete. Sometimes, however, the cracks are a warning sign that the foundation is experiencing problems, like settling, or it could have issues with hydrostatic pressure from around the foundation which can cause walls to lean into the basement of a home.

If there are cracks in the foundation wall, water will eventually make its way inside through these cracks.  It may start as a trickle of moisture at first, but over time water will start to seep into the home in very large quantities.

Warning signs of leaking wall cracks

1. Water can be physically seen dripping down from a crack.

2. Stains or obvious signs of water damage are seen on the walls.

3. Puddles of water appear on the floor below the crack.

4. Mold starts growing on the wall under or around the crack itself.

5. The crack appears to be getting bigger and bigger in depth and size.
