Why your neighbors trust Groundworks

We've earned 1,050 five star reviews.

"Excellent experience, overall! Everyone we spoke to, from the initial estimate to setting up appts, to the installation, they were all absolutely lovely and professional. The crew was communicative, showed up on-time, walked us through their POA for the day, had us take a look at their progress periodically, and even finished earlier than estimated. They were thoughtful of our property and answered all of our questions. (We had a lot 😅) Grateful to have found people that are not afraid of hard work and take pride in the finished product. So refreshing! Keep it up!"

Types of Basement Damage in Wilmington

Common Causes of your Basement Problems in Wilmington

Hydrostatic Pressure

When groundwater accumulates around your foundation, it exerts pressure on basement walls and floors, leading to cracks and water seepage.

Poor Drainage Systems

Inadequate drainage systems fail to divert water away from the foundation, resulting in water accumulation that can compromise structural integrity.

Foundation Cracks

Natural settling or poor construction practices can cause foundation cracks, allowing water to penetrate your basement.

Gutter and Downspout Issues

Improper installation or clogging of gutters and downspouts directs water toward the foundation, exacerbating water infiltration problems.

High Water Table

During heavy rainfall or snowmelt, a high water table exerts pressure against basement walls, causing water to seep through cracks or joints.

Plumbing Leaks

Leaks from plumbing systems can saturate the soil around the foundation, leading to erosion and weakening of the structure.

Understanding these common causes can help you take proactive steps to protect your basement from water damage and maintain the integrity of your home.
