What Is Hydrostatic Pressure, and Why Is It a Problem for Your Basement?
Hydrostatic pressure is a common cause of basement flooding and foundation damage. If you notice cracks or bowing in your basement walls or foundation, you may have too much water pressure underneath your basement. Reaching out to a professional waterproofing company can help mitigate the damage and protect your home from lasting damage.
Dry Tech Waterproofing Solutions has been a trusted provider of basement waterproofing and drainage services for 25 years. We work with homeowners and commercial property owners in Pennsylvania, Delaware, and New Jersey, to protect against hydrostatic pressure and its complications. Here, our team discusses what hydrostatic pressure is and how it affects your basement.

What Is Hydrostatic Pressure?
The ground around your home normally has water in it. However, if too much water collects around your foundation, it can lead to problems. Water has a density of 60 pounds per cubic foot or 997 kilograms per cubic meter, and this weight increases with depth. The force of this water presses against your foundation and basement walls. If the water doesn’t drain properly, large pools of water may start to form. The larger the pool of water, the greater the pressure exerted onto your basement and foundation. If the hydrostatic pressure around your foundation is too high, you may start to notice the following:
- Cracked foundations
- Moisture leaks and puddles
- Uneven or heaving basement floor
- Building or bowed basement walls
- A musty mold or mildew odor
Waterproofing Services in Delaware, New Jersey, and Pennsylvania
If you notice damage to the walls and floors of your basement or foundation, hydrostatic pressure may be the culprit. Luckily, there are ways to mitigate the damage before it becomes too extensive. The longer you wait to address the problem, the higher your chance of harmful mold developing in your home.
If we suspect hydrostatic pressure is to blame for your foundation and basement issues, our experts will perform a hydrostatic pressure test. This test utilizes moisture meters to determine the amount of pressure water is placing on your walls and floor. This helps us detect exterior drainage issues and develop a customized waterproofing solution for your home, including:
Basement Waterproofing

Even if your home doesn’t have a basement, hydrostatic pressure can cause damage to crawl spaces throughout your home. We provide crawl space repair services with lifetime transferable warranties to help protect your home from future damage. Our experts will eliminate water and humidity and replace warped or rotted beams in your crawl space, benefitting you in the following ways:

- Increasing the structural stability of your home
- Preventing pest infestations
- Decreasing heating and cooling costs
- Preventing floor sloping, buckling, and damage
Drainage Services
One of the most common causes of water pooling around your foundation is improper drainage. If the water in the soil can’t drain properly after the snow melts or during a heavy rainstorm, the increased hydrostatic pressure can cause flooding or foundation damage. At Dry Tech Waterproofing Solutions, our yard drainage services include the following:
- French drain installation: We install French drains and perforated pipes in your yard. Water seeps into the pipes, carrying it away from your yard.
- Dry well installation: We bury a storage tank in your yard, which stores the excess water. The water then slowly seeps into the soil around it during drier weather.
- Trench drain installation: Trench drains have elongated surfaces to collect water. These drains move it away from your foundation, reducing the amount of standing water.
- Sump pump installation: Sump pumps gather excess water in your basement or yard. These powered devices pump it away, even uphill.
Foundation Repair
When hydrostatic pressure causes damage to your foundation, our foundation repair experts can restore its structural integrity and help prevent wall failure. We’ll repair cracks to prevent water from seeping in and causing further damage. Then, we’ll stabilize your foundation to increase its longevity. We’ll also apply a protective, waterproof coating above the ground portion to help keep water out.
Mold Remediation
Damage caused by hydrostatic pressure can lead to harmful mold growing in your home. If you notice peeling paint, an eroded foundation, a musty smell, or small spots, call our mold remediation experts. We use proven techniques, advanced technology, and the best methods and materials to remove any visible—and invisible—mold from your home. Once we remove the mold, we’ll inspect your home to find the source and waterproof your basement to prevent future growth.
