What is Hydrostatic Pressure, and What Causes it?

Hydrostatic pressure is the force that standing water exerts against basement walls. This pressure is usually caused by soil saturation after heavy rain or snowmelt.

Regions with high water tables and certain soil types, such as expansive clay, are more susceptible to hydrostatic pressure.

4 Ways to Prevent Hydrostatic Pressure

Ideally, hydrostatic pressure prevention will begin during the initial home construction phase. Builders incorporate these methods into the site and foundation design. However, many homeowners are far past this stage and require immediate solutions.

Below are a few steps you can take to prevent hydrostatic pressure.

1. Improve Drainage

Excessive water and poor drainage lead to significant foundation problems. Exterior drainage systems are effective for preventing hydrostatic pressure, as these systems prevent water accumulation. Ensure proper drainage by:

  • Ensure gutters and downspouts point away from the foundation. This approach directs water away from the foundation, preventing accumulation and seepage.
  • Yard and landscape grading should slope downward and away from the foundation. Proper grading allows natural water flow, reducing the risk of water pooling and hydrostatic pressure.

2. Install an Interior Drainage System

Proper interior drainage systems help prevent hydrostatic pressure. Installing a professional interior drainage system containing a sump pump is the best solution for preventing water pooling and basement flooding. These systems collect and remove water from your basement, preventing damage. 

3. Seal Cracks

How Does Hydrostatic Pressure Affect Your Foundation?

When the soil becomes saturated with moisture, it expands and pressures foundation walls. This increased pressure can force water through cracks in foundation walls and into the basement, causing flooding.

Hydrostatic pressure can also cause bowing basement walls. Addressing water infiltration with professional solutions is essential to preventing significant damage.

Basement Waterproofing FAQs

If your basement walls are wet, it can be a sign that there are deeper problems at play in your home. Cracks in your basement walls and foundation are the most likely source of wetness in your walls and floor, but these can be caused by a variety of issues. Hydrostatic pressure, faults in poured concrete walls, settlement, and abnormally heavy rainfall can all cause this kind of damage.

We do not recommend DIY basement waterproofing. While sealing basement walls may seem like a quick fix, it is crucial to address mold and mildew issues first. Contact a professional to identify, repair, and prevent leaks rather than attempting a DIY patch-up.

Basement waterproofing is definitely worth it. It enhances your home’s value and appeals to potential buyers, offering immediate and long-term benefits for your property.
