Job Stories From Lake Oswego, OR
Cracked Retaining Wall Fixed with Geo-Lock Anchors

    A new restaurant is opening in Lake Oswego and the new owner wanted to make sure not only was the food excellent but the ambiance, feel and venue was as fantastic as the food. This included repairing a retaining wall along the side of the building that, over the years, has began to lean and now rests at a 15 degree angle. Bryce B. wanted to straighten the wall to look better, but also to restore the structural aid it provided. After asking around to his friends and family he found TerraFirma and scheduled a free inspection.

    To provide lateral stability, 3 Geo-Lock Anchors were installed. Anchor plates are secured on the outside of the wall, and a fews feet back into the soil. They are connected with a rod. The plates act as an anchor and the wall is literally cranked back upright. Since the plates are secured in place, the wall is the only thing that can moves and is eventually straightened. With the use of 3 Geo-Lock Anchors, Bryce was able achieve both of his goals. Ready for grand opening late summer!

McGinnis Finding the Right Cleanspace Installer Lake Oswego, OR

    For home improvement projects there are tens and hundreds of different solutions out there; However, There are two key pieces to a successful home improvement or repair project. 1, Finding an efficient, durable, long lasting solution. 2, Finding a qualified installer of that system. Lake Oswego, OR home owners Amy & Shane M. had their crawl space encapsulated a few years back by a different company, but as of late are noticing moldy smells throughout the home. After seeing a TerraFirma ad in Portland Monthly, they called the real experts for finally solve their crawl space issues.

    After inspection by Josh Anderson, they had the right product and solution under their home, but they failed to find a qualified installer. Our improvements included a drainage system collecting ALL the water entering the area, and closing off the vents. By closing off the vents, and removing all the water Amy and Shane now have 100% control over the air underneath their home.

    Not all solutions are created equal, nor are they installed equally. Do your research and make sure you are using the real experts in the industry.

Complete Foundation Failure Revived Lake Oswego, OR

    There is a problem with home projects. Typically, they don't fix themselves. And, Typically they get worse over time especially if not addressed. Lake Oswego, OR, home owners Jim and Glenda D. have a worst case scenario. Their crawl space was humid and wet causing structural damage and mold development. Because of the pooling water the  foundation settled vertically, horizontally and torsionally. After searching for options to save their home before it went flushing down the hill, he found TerraFirma who could help with all of these issues.

    The services we performed on Jim and Glenda's home were as follows. A Cleanspace crawl space encapsulating system that would stop groundwater seepage, separate the cold earth from the house, condition the air and close off crawl space vents. These products, working together, keep air warmer, control all water issues in the crawl space, save money on heating bills and cleanse the air. The root of the problem was solved. Next we solved the side effects, the settling foundation. to stabilize vertical settlement, push piers were installed along the back side of the home on the downside of the hill. these piers were secured to the foundation footing and anchored into load bearing soil below. To stabilize horizontal and torsional settlement and stress, helical anchors and wall plates were installed. 10 to be exact. These anchors grabbed soil working against the direction of horizontal settlement to halt all movement.

    This project took Jim and Glenda 2 years to get city approval and schedule a date of installation. Luckily we got there in time before the entire foundation was sacrificed. Jim and Glenda look forward to enjoying their dream home until they are old a gray and don't have to worry about it sliding down the hill anymore.
