Job Stories From Oregon City, OR
Foundation Failure Rehab Gladstone, OR

    There is no worse situation than foundation failure for a home owner. Watching your home and investment crack and crumble away right in front of your eyes is something no one wants to be a part of. Soils expand when they absorb moisture and contract when dried. The cycle repeats itself every year. Some years more severe than others. This was the case for Gladstone home owner Brenda Q. who, over the years has noticeably watched her house creak, crack and moan as it settled into the ground. Doors and windows were misalign. Dry wall cracks appeared in every corner. Her home was literally separating away from the steps that lead up to it. After searching the internet for foundation repair, Brenda found TerraFirma and scheduled a free inspection by Bryan Cantrell. 

    Upon inspection, there was a lot of high attention areas, but the main settlement had occurred around the garage. The settlement had pulled other parts of the home, steps and surrounding structures down with it as an aftermath to the original settlement. A combination of 16 helical piles and push piers were designed to permanently stabilize the foundation, steps and surrounding structures not only preventing them from further settlement, but were also used to lift the foundation back to level. To solve the unevenness and cracking of the garage slab and driveway, PolyLEVEL was injected into the sub voids, lifting, supporting and leveling the sinking slabs.

    This was a comprehensive solution to one serious problem. Soil settlement can cause great damage to a home and property. In the northwest, these events are unfortunately inevitable in some cases. Just make sure you know the signs and who to call if this were to happen to you.

Foundation Stabilization from Crawl Space Interior Oregon City, OR

    Home owner Gordon L. of Oregon City, OR began noticing sign of  foundation settlement a few years back throughout his home. Cracks have widened in the dry wall, a few windows that were once just sticky, were now jammed shut 5 years later and the floors had began to sag. These are the classic symptoms of foundation and interior settlement. After seeing a TerraFirma commercial, Gordon called our offices to schedule a free estimate.

    As inspected by System Design Specialist Ryan Lahley, he confirmed that there had been comprehensive settlement of Gordon's exterior and interior foundation. The interior settlement was solved by the use of 2 Smart Jacks to support the main load beams. The foundation settlement issue was solved by an 11 push pier system around nearly 1/3 of the home perimeter. The crawl space was nearly 4 feet tall and allowed foreman Jon Kaes and crew to work inside. The work and final result is the exact same as though they worked from the outside of the foundation as we usually do, but now Gordon won't have to worry about any destruction to his yard or garden.

    Since stabilization, Gordon's floor doesn't sag and he can be confident his foundation will be permanently stabilized for many years to come.

Crawl Space Repair Oregon City, Oregon

    Converting a crawl space from a wet, cold and moldy environment to a completely encapsulated, insulated, dry and conditioned environment is an improvement any home owner show make. Crawl spaces were constructed instead of basements because they were cheaper to build. By leaving the home exposed to the earth below, two major problems arose. Moisture problems and unconditioned air.

    Darlene B. of Oregon City, Or had both of these issues, and Darlene was looking to address them immediately. The excess water in her crawl space caused cracking in the foundation wall as well. To repair the cracking, Carbon Armor was applied directly to the wall crack to provide and restore support. To cure the moisture and unconditioned air problem a variety of systems were installed. A trench waterproofing drain around the perimeter and through the middle to collect water and redirect to a sump pump for removal. Cleanspace liner to isolate the earth from the house. A dehumidifier to condition and control the air quality and Everlast Vent Covers to completely encapsulate the area. to go the extra mile SilverGlo wall insulation along the walls to keep air warmer and lower heating bills.

    Darlene can now be happy and excited about her new living space. It is warmer, healthier, and more comfortable year round.

Comprehensive Foundation Repair System Oregon City, OR

    Jeanne C. of Oregon City, OR owns a home in need of complete foundation repair. It is hard to which issue came first. Was it the perimeter foundation settlement? Interior settlement? Or her sinking slab. Needless to say she has an issue and needs to be addressed immediately before complete foundation failure is the result. After being referred to us by a friend, Jeanne C. scheduled a free appointment to have her foundation inspected.

   There are three problems here with three unique solutions. To solve the perimeter foundation settlement issue, five push piers were installed around the back corner of the home. Brackets are permanently secured to the foundation footing and steel piers driven down to load bearing strata or bed rock. This will permanently stabilize the foundation. Three Smart Jacks were installed under the main load beam under the house to restore structure and stability to the interior portion of the home. This reinforcement will stabilize the "bounce" and "sagging" along the middle area of the house. Lastly, PolyLEVEL, which is a lightweight polyurethane will be injected underneath the sinking cement slabs to lift and level all uneven slabs.

    Three efficient fixes for three unique problems. Jeanne can now be confident that her house is permanently stabilized and her and her family can enjoy it for many years to come.
