Job Stories From Washington County, OR
Restoring Beauty in Beaverton, OR

    In Beaverton, OR, home owner Joel K. had three areas of concern around his home and called us to have a look at his situation. The front covered patio, back patio and a walkway had settled and were now cracked and slanted. A very unsightly feature of his home that he wanted fixed. After an inspection by Adam Lounsbury, TerraFirma Concrete Leveling was the advised solution.

    Our concrete leveling solution is a light weight polyurethane that is designed to provide support to sinking slabs above while adding little-to-no load to the soils below. After drilling a hole in the sinking slab to expose the void, polyurethane foam is injected. It expands and fills the void evenly achieving uniform and calculated lift to the slab. In just a few short hours, Joel's slabs are leveled, the project site is cleaned and looking beautiful again.
