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 shelf life of concrete depends on whether it's wet or dry. Ready-mixed concrete in its wet form lasts approximately 90 minutes to two hours after water is added, so it is essential to schedule your delivery carefully. Bags of dry concrete mix can last several months if stored properly in a cool, dry place. Moisture exposure can cause the cement to harden or lose strength over time.
An average concrete truck can hold between eight and 11 cubic yards of concrete, although some larger trucks can carry up to 15 cubic yards. However, road weight limits often restrict the amount they can carry, so most deliveries are around eight to 11 cubic yards. Knowing this helps you plan the number of truckloads you'll need for your project.
Pouring concrete doesn't take very long once the truck arrives. One cubic yard of concrete can be poured in about 10 minutes. Therefore, a full truck with 10 cubic yards of material would take approximately one hour and 40 minutes to empty. Keep in mind, though, that preparation and finishing work add time to the overall project.
Concrete sealing typically costs between $1,400 and $3,000. A high-quality sealer forms a durable barrier that blocks moisture, chemicals, and stains, helping the surface resist cracking and discoloration. By protecting the slab now, you avoid costly repairs later and extend the concrete’s lifespan. For best results, pros thoroughly clean the surface and apply the product evenly at the manufacturer’s recommended coverage rate.
Installing a standard concrete walkway costs around $1,800 for 200 square feet, which usually translates to a 3-foot-wide, 65-foot-long path poured to a 4-inch thickness. That figure includes both materials and professional labor. Reinforcement, coloring, or decorative finishes can raise the price, as can increasing the slab’s thickness to support light vehicle traffic. Knowing the dimensions and intended use in advance helps your local concrete contractor quote accurately and avoid surprise add-ons.
A concrete slab costs between $3,600 and $7,200. The final price depends on thickness, reinforcement, and site preparation. Basic residential pours use a 4-inch slab, but garages or workshops may need extra depth or steel rebar, which drives up material and labor charges. Some homeowners opt for prefabricated slabs delivered to the site, trading higher transport fees for quicker installation and consistent quality. Discuss load requirements and soil conditions with your contractor to choose the most cost-effective option.
