TerraFirma Foundation Systems

TerraFirma Foundation Systems is a foundation repair and basement waterproofing company at 13110 SW Wall St in Tigard, Oregon. Its site says it has served homeowners since 2005 across Oregon, Washington and Idaho, including Portland, Eugene, Seattle, Tacoma, Vancouver and Boise.

The site covers foundation repair for settling floors, crumbling walls and support posts, with solutions listed as foundation piers, wall stabilization and crawlspace support. It also covers basement waterproofing, crawl space repair, concrete repair and leveling, and earthquake retrofitting. The pages we read describe its piers generally and do not clearly say whether they are helical or push piers.

To schedule an estimate, call 866-486-7196. Because the pier type is not stated, ask which pier system is proposed for your home and why, what engineering supports the design, how load and depth are verified, and what the warranty covers.
