Job Stories From Kalama, WA
Southwest Corner of Home Settling in Kalama, WA

Danielle W. noticed the southwest corner of her 2013 single-family home had settled in Kalama, WA. Not wanting the settling to get worse as she prepared to sell the house in a few years, she reached out to TerraFirma for help. 

System Design Specialist Jacob Iltis met with Danielle and evaluated the property. The home had a differential settlement of 1 inch from the high point on the east side to the low point on the southwest side. There were a few cracks in the foundation on the south side of the home as well, so Jacob recommended installing TerraFirma Push Piers to stabilize the south wall.

With Jacob’s recommendation, Roberto Burgos and his crew went to work, stabilizing Danielle’s house within one day! 


Concrete Leveling for Slanting Slabs Around Pool Kalama, WA

    It's hard to imagine a better summer day than friends, family, BBQ and a pool party. Think about this. After the cement pool is poured and the water is filled, you can imagine how heavy a structure like that must weigh. Home and pool owners Darren and Adriane O. noticed a slanting of the slabs around their pool and wanted to level this issue without massive destruction around the pool area. It is almost summer after all, and they wanted to take advantage of their pool. After searching the internet, they discovered that TerraFirma could help them out.

    TerraFirma Concrete Leveling was the solution they discovered. What it is, is a light weight poly urethane with a high capacity and expansive properties. A penny sized hole is drilled in the sinking slab with the void underneath and the foam is pumped into the void. It expands, stabilizes the slab and with measurable lift. With next to no destruction and curing quickly, Darren and Adriane O. can enjoy their pool all summer long worry free.
