Roseburg & Medford’s Preferred Foundation & Concrete Repair Experts
Southern Oregon’s diverse climate and soil conditions present unique challenges for homeowners in Roseburg, Medford, Grants Pass, Klamath Falls, and Coos Bay. Unlike the consistently wet conditions of Portland, these areas experience a wider range of temperatures and moisture levels, leading to varied soil behaviors.
Inland areas including Medford, Grants Pass, and Roseburg often experience hot, dry summers followed by wet winters. This fluctuation in moisture content causes significant soil expansion and contraction, particularly in areas with clay-rich soils. This can result in foundation settling, cracking, and uneven floors. Call us today at (866) 486-7196

Roseburg Homeowners Frequently Asked Questions
What types of cracks in my foundation or basement should I be concerned with?

Why is it important to repair a concrete crack?
Concrete cracks aren’t just unsightly; they offer moisture a way to seep beneath the slab. This can cause the underlying soil to soften or even wash away completely. That in turn can cause the slab to crack further as it sinks into the void left by the washed-away soil.
What are the benefits of installing a crawl space vent cover?
Crawl space vent covers play an important role in sealed crawl spaces by closing out the air movement that would otherwise occur through vent openings. Sealing your crawl space with vent covers saves you money by blocking air movement and decreasing the temperature fluctuation that is known to increase energy bills.
What is the difference between helical piers and push piers?
Houses built on hills or with a hot, southern-facing exterior are particularly susceptible to unstable soils. In the Pacific Northwest it is important to look out for expansive soils that absorb water and expand. Also common to the region are Consolidating Soils that shrink and compact.
What’s the best way to repair concrete?
Available to be installed year-round, the NexusPro solution offers several advantages over traditional concrete crack repairs. Its fast cure time (60 minutes) and performance under extreme temperatures makes it a perfect match for concrete repairs in Seattle, Kirkland and throughout the Pacific Northwest.
How to fix moisture issues in your crawl space?
Water that seeps into your crawl space can serve as a breeding ground for pests, mold, and odor. Crawl space encapsulation by TerraFirma can help you address crawl space issues ranging from poor drainage to damaged foundation.
How to repair a sagging crawl space in Roseburg and Grants Pass?
In many cases, a failing crawl space structure can be resolved by installing crawl space supports. This is a fast job that can provide permanent, warrantied results. Typical installations can be completed in less than two days.
Can vents relieve the excess moisture in my crawl space?
Vented crawl spaces let in outside air that can increase heating bills in the winter and cooling bills in the summer, and actually lets more moisture into our homes! By encapsulating the crawl space with our VaporLoc® system, we can close your crawl space vents for good.
What are the soil conditions in Roseburg and Coos Bay?
Expansive soils, present in the Pacific Northwest, absorb water and expand. This exerts significant pressure against the foundation and causes it to move. This might cause your foundation to settle or sink.
Also common to the region are Consolidating Soils that shrink and compact. This undermines the foundation, making it unable to support the weight of the house evenly. Houses built on hills or with a hot, southern-facing exterior are particularly susceptible.
