Basement Floor Leveling in Seattle

Basement floors can settle, slope, or crack over time due to soil movement and moisture changes. Basement floor leveling restores a flatter surface, improves safety, and prepares the space for finished flooring or storage.

If you notice low spots, uneven transitions, or persistent cracks, a professional evaluation can determine whether concrete leveling is the right solution for your basement.

Common causes of uneven basement floors

Basement slabs can shift for several reasons, including soil settlement, poor compaction, plumbing leaks, or seasonal moisture changes. In the Seattle area, heavy rain and drainage issues can worsen movement beneath the slab.

Basement floor leveling methods

Leveling methods vary based on the condition of the slab. Grinding can remove minor high spots, while self-leveling overlays can smooth shallow dips. For larger voids or sinking sections, slabjacking or foam injection can lift the slab back to grade.

When to repair vs replace

Concrete leveling works best when the slab is intact but uneven. If there are large structural cracks, ongoing water intrusion, or severe deterioration, a more extensive repair or replacement may be recommended.

Preparing for finished flooring

A level surface is critical before installing LVP, tile, carpet, or epoxy coatings. Basement floor leveling helps ensure these finishes install correctly and last longer.
