Thousands of NW homeowners have trusted TerraFirma Foundation Systems to keep their homes safe, dry and stable since 2005. Nearly half of our business comes from referrals or repeat customers. We can help you too! TerraFirma is the NW expert in home foundations, basement and crawl space waterproofing, concrete leveling, and wall stabilization.
"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they “completed the job,” I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they’re saying that leveling the kitchen wasn’t included in the original scope, blaming the remaining dip on my kitchen island and fridge being “too heavy” and lacking proper support—an issue they failed to identify in the initial assessment. To properly address this problem, they’re now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I can’t help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that wasn’t there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as “standard” and providing terms within the contract absolving them—despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to “settle naturally”—a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you’re considering foundation work, I strongly recommend looking elsewhere—this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

The installation process for a concrete basement floor spans several days to weeks, depending on project scope. Preparation work includes removing existing flooring, creating proper drainage, and establishing a suitable base. The concrete itself requires adequate curing time before finishing treatments can be applied. Weather conditions, basement accessibility, and chosen finish types all influence the overall timeline.
Concrete slabs are constructed at ground level as part of a foundation system, while basement floors are installed below grade within an existing foundation structure. Basement installations often require additional moisture control measures due to their subterranean environment. Both utilize similar materials, but basement floors frequently need specialized preparation to address ground moisture issues and integration with existing foundation walls.
While some preparatory aspects might be manageable for experienced DIYers, concrete basement floor installation requires professional expertise. The process involves precise measurements, proper reinforcement placement, and skilled finishing techniques. Errors in mixing, pouring, or curing can lead to significant structural problems. Most homeowners find that professional installation, though more expensive initially, provides better long-term value and performance.
Proper maintenance includes regular sweeping and occasional mopping with appropriate cleaners. Avoid harsh chemicals that might damage sealants or concrete surfaces. Address spills promptly to prevent staining. Inspect periodically for cracks or signs of moisture problems. Reapply sealants according to product specifications to maintain moisture resistance. Controlling basement humidity helps preserve the floor's condition over time.
A properly installed concrete basement floor can improve moisture management when incorporated with appropriate waterproofing measures. Vapor barriers, drainage systems, and quality sealants all contribute to moisture control. However, concrete alone cannot resolve serious foundation water issues or hydrostatic pressure problems. Comprehensive waterproofing approaches that address exterior drainage, foundation walls, and interior systems provide the best results for persistent moisture concerns.
