Because of the wet environment from the previously un protected crawlspace, the floors began to sag. Smart Jacks re-support these beams and prevent sagging.

Usually we can place our machine right next to where the helical tiebacks are being drilled in. We can't really do that here so this contraption was made to achieve the right amount of stability for helical tieback installation.

Like magic, we are in the ground. We had to cut through cement, rock, roots, etc to get a good fasten. Now we are secure and in the ground and moving in the right direction.

Job Stories From Clackamas County, OR
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, our concrete leveling solution, 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.

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, Our polyurethane foam concrete leveling solution 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.

Concern for possible Sinking/Settling Foundation
Project Location: Clackamas, OR
Need an evaluation of our crawl space - minor water retention and an estimate on a sump pump or other solutions on waterproofing the area. Thank you
Project Location: Clackamas, OR
The last section of sidewalk leading to my front step, porch, landing, or whatever you want to call it, has sunken about 1-1/2 inches on one corner. I am looking for someone that can raise that section, to it's original height rather than cut it out, put in a couple of pieces of rebar, reform, pour and try to match the existing "exposed aggregate finish". The section in question is about 4x5 feet. I realize this is a "small job" to most construction workers, but I would really appreciate a bid to repair (raise)this potentially accident prone situation. I am retired so I can be around most anytime that one of your people could come look over the situation.
