Job Stories From Happy Valley, OR
Liu Happy Valley, OR Crawl Space Encapsulation

    Happy Valley, OR is located in the hills on the eastern border or Portland with a collection of beautiful homes overlooking the west side of the city. Happy Valley is also the location of multiple "Street of Dreams" events. The "Street of Dreams" is a home builders dream in which million dollar homes are built to inspire creativity and wow the imagination with a focus of home efficiency. So it is no wonder that Happy Valley home owner Henry Liu was interested in encapsulating his crawl space. Henry searched the internet for a qualified installer and called TerraFirma for a free estimate. 

    By encapsulation your crawl space you achieve many things. One of which is energy efficiency and healthy air conditioning. The goal of encapsulating your crawl space is to condition and control ALL the air under your home. By controlling groundwater seepage, isolating the earth from the home and blocking off the vents, Henry is able to control 100% of the air in his crawl space. Crawl space air accounts for 50% of the air on the first story of your home, and 50% of that for each additional floor. With healthier, mold free air, we have achieved one of Henry's main goals. By insulating the crawl space, air stays warmer under the home. This means less energy is used to heat the house making it not only more comfortable but cost effective to maintain. 

    A simple three day project gives home owners, like Henry, healthier, more comfortable and cheaper living. The project pays for itself after a few years. 

Happy Valley, OR Settling Slab Leveled with PolyLEVEL

    Home owner Ken H. of Happy Valley, Oregon noticed that the stamped patio pad in his back yard had began to settle. As much as 1.5" in some places. Ken was done looking at unsightly cracks and the unfinished look to his back yard and wanted to do something about it. After seeing a PolyLEVEL commercial from TerraFirma, Ken called to set up his free estimate.

    A quick curing, low density, high capacity polyurethane called PolyLEVEL was injected into the void under his sinking slab. PolyLEVEL is pumped through a penny sized hole and expands evenly to uniformly raise the sunk slab back to level. The solution cures in about 12-20 minutes and clean up is a since. This is a very efficient and cost effective solution to slab repair in comparison to the other option of demolish and replace.

    Ken now has a new back yard patio slab without the price of one just in time for Summer.

Slab Leveling Saves House From Potential Water Damage Happy Valley, OR

    Voids under cement slabs can occur in two main ways. One is that the soil under the home settles. When this settlement occurs a voids results. The second main cause is when water flows under the slab, washing away the soil. Again, this will lead to voids. In the case of Mark P. of Happy Valley, OR sinking slabs have changed the angles, layout and geography around the perimeter of the house. When it rains, the water is now being directed TOWARDS the foundation rather than away. This is a problem.

    The solution is simple. PolyLEVEL Injection! The way this installation works is as follows. A penny sized hole is drilled into the sinking slab. PolyLEVEL, a lightweight, quick curing polyurethane is injected into the void. The expansive properties of the polyurethane inflate to evenly fill the ENTIRE void. Due to the high capacity of PolyLEVEL, the slab is pushed up, leveling the area, and in this case, saving the foundation.

I have a daylight basement with a musty smell. We thought it was due to a leaky window in the basement, but that was fixed and the musty smell persist. Today, I looked in the crawlspace and there appears to be water coming in from where the driveway and garage meet. I was hoping someone could come out to determine if that is the source of the problem or not and provide a quote to remedy the problem.
