"Matvey/Groundworks resurfaced my garage floor in Bellingham. The team showed up early, prepared for a little rain, got to work and completed the job by about 4:00. pm. They were friendly, professional, fully independent, and did an excellent job cleaning up. The floor looks fantastic, with even disbursement of the flake and nice clean edges. Thanks guys!"

Types of Basement Damage in Bothell

Common Causes of your Basement Problems in Bothell

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.
