Floors that bounce, sag, or feel uneven
Basement walls that bow inward or show stair-step cracks

The TerraFirma Advantage: Every foundation repair includes comprehensive soil analysis, engineered solutions specific to Multnomah County conditions, and transferable warranties that protect your investment even if you sell your home.
Don’t wait for foundation problems to worsen—every month of delay typically increases repair costs and reduces your options.
Basement cracks, leaks or Settling?
TerraFirma can fix them all. We’re your top rated basement repair contractor for:
We want to make your home dry, level, and safe. TerraFirma has waterproofed basements for over 20 years from Medford to Salem, and Vancouver to Tacoma.
Basement Waterproofing: From Wet and Musty to Dry and Usable
Transform your basement into valuable, healthy living space
A dry basement isn’t just about preventing floods—it’s about creating healthy air throughout your entire home and protecting your family’s largest investment. Homeowners across Multnomah County, especially those in Multnomah, trust our waterproofing systems to eliminate moisture problems permanently, not just temporarily.
Complete Moisture Management:
- Interior Drainage: WaterGuard®, DryTrak®, and FlowGuard® systems custom-designed for your foundation type
- Powerful Sump Protection: TripleSafe™ three-pump systems with battery backup, plus UltraSump® emergency pumps that operate during power outages
- Air Quality Control: SaniDry Sedona and XP dehumidifiers that remove up to 109 pints daily while filtering mold spores and allergens
- Complete Sealing: VaporLoc Elite wall systems that direct any moisture into drainage systems rather than into your living space
Beyond Basic Waterproofing: Our systems work together as an integrated solution. Drainage handles the water, sump pumps remove it quickly, dehumidifiers control humidity levels, and vapor barriers prevent future moisture problems. The result? A basement that adds value to your Multnomah home instead of detracting from it.
Seasonal Protection: Multnomah County’s winter rains and spring snowmelt create peak moisture challenges. Our systems handle maximum water loads automatically, giving you confidence during the wettest months.
Crawl Space Repair: From Neglected Problem to Structural Asset
Turn your crawl space into a clean, dry foundation for healthy living
Your crawl space affects every breath you take in your home. With up to 50% of your indoor air originating from below, a properly maintained crawl space isn’t optional—it’s essential. Residents in Multnomah discover that crawl space encapsulation often solves mysterious odors, high energy bills, and even respiratory issues.
Complete Encapsulation Process:
- Moisture Elimination: VaporLoc Elite 120-mil barriers that block ground moisture, soil gases, and pest intrusion permanently
- Structural Support: SmartJack® adjustable steel posts that eliminate floor bounce and prevent sagging
- Climate Control: Professional-grade dehumidifiers with automatic drainage and humidity sensing
- Access Solutions: EverLast™ doors and Turtl™ access wells that keep moisture and pests out while providing secure entry
Advanced Monitoring: Our ShipShape™ system provides 24/7 performance monitoring, proactive maintenance alerts, and remote control capabilities—giving Multnomah homeowners complete peace of mind about their crawl space conditions.
The Health Connection: Proper crawl space conditions reduce allergens, eliminate musty odors, and improve indoor air quality throughout your home. Many Multnomah homeowners notice immediate improvements in comfort and energy efficiency.
Concrete Repair: From Hazardous to Beautiful
Restore safety and curb appeal with advanced concrete solutions
Cracked, uneven concrete isn’t just unsightly—it’s a liability waiting to happen. Throughout Multnomah County, TerraFirma’s concrete repair solutions eliminate tripping hazards, improve drainage, and restore your property’s professional appearance in just hours, not days.
PolyLevel® Concrete Lifting: Our advanced polyurethane foam injection system lifts and stabilizes concrete slabs with precision control. Unlike messy mudjacking, PolyLevel cures in 15 minutes, weighs only 4 pounds per cubic foot, and provides permanent support even in the weak soils common to Multnomah and the broader region.
Complete Protection Package:
- NexusPro™ Sealant: UV-resistant joint sealing that cures in 60 minutes and includes color-matched sand for a polished appearance
- SealantPro™ Surface Protection: Deep-penetrating concrete sealer that prevents stains, flaking, and weather damage
- Commercial Applications: We also service industrial facilities, warehouses, and municipal projects throughout Multnomah County
Weather-Resistant Results: Our systems withstand Multnomah County’s freeze-thaw cycles, heavy rainfall, and temperature extremes while maintaining their appearance and functionality year after year.
Earthquake Retrofitting: From Vulnerable to Code-Compliant
Secure your home against Pacific Northwest seismic activity
The Cascadia Subduction Zone doesn’t operate on your timeline. Homes built before the 1990s weren’t designed for the seismic realities we now understand. TerraFirma’s earthquake retrofitting services transform older homes into structures that can withstand seismic events while potentially reducing your insurance premiums and qualifying you for coverage that wasn’t previously available.
Comprehensive Seismic Protection:
- Foundation Anchoring: Steel anchor bolts that prevent your home from sliding off its foundation during ground movement
- Shear Wall Installation: Plywood reinforcement in cripple walls that distributes seismic forces safely
- Structural Bracing: Steel straps and braces in critical load-bearing areas
- Utility Securing: Water heater, gas meter, and appliance anchoring to prevent dangerous post-earthquake hazards
Insurance Benefits: Most retrofitted homes qualify for reduced earthquake insurance premiums, lower deductibles, and coverage options that weren’t available before retrofitting. Many homeowners recover their retrofit investment through insurance savings within a few years.
Code Compliance: Our retrofits meet or exceed current seismic building codes, ensuring your Multnomah home is prepared for the ground motion conditions specific to Multnomah County’s geological characteristics.
