Expert Foundation and Basement Repair near Portland and Vancouver

Situated in the Pacific Northwest, Portland and Vancouver share
similar weather conditions and rain showers throughout the year.
These rains, while nourishing the landscapes of the region, are
constantly testing your drainage system and making basement
waterproofing a priority.

Despite the prevalence of rain, the climate in Portland and
Vancouver also offer plenty of sunny days. Nearby cities like
Hillsboro, Beaverton and Oregon City, also sit in an area where
soils can expand significantly (expansive soils) when they
absorb water and contract when they dry out.

This cycle of expansion and contraction can put pressure on
foundations, leading to cracks and structural damage over time.

Concrete Driveway & Sidewalk Lifting & Leveling in Portland,
Tigard, and Beaverton

Portland’s damp climate can lead to sunken driveways, cracked or uneven sidewalk slabs, deck and patio deterioration, and more. Many homeowners are surprised that concrete can be lifted and leveled with much less cost and hassle than removing and replacing cracked or uneven concrete.

TerraFirma’s PolyLevel polyurethane foam solution has successfully lifted and leveled concrete slabs throughout Hillsboro, Tigard, the Dalles, Vancouver, and Longview.

Don’t take our word for it – see what our clients have to say.
From Vancouver to Beaverton, Gresham to Clackamas, and throughout the Portland area, our work speaks for itself.

been just over a month of hard rain and no leaks, guess it works
We had two companies come and provide evaluations of our foundation repair needs. TerraFirma was by far the most professional and responsive company. In the end we did not go with the lowest bid but we did go with the company that provided the most professional response and gave use the most confidence it would be done right. We were not disappointed 🙂
The guys were fantastic. Any requests I made were immediately address in the most professional manner. I love my house now. Neither my husband nor myself have had respiratory issues like before we had Terra Firma seal our foundation and add the dehumidifier. The best part is that I don’t have to empty the dehumidifier and my house is dry now. I would totally recommend this service!!’
