Concrete contractor in Mountlake Terrace, WA

Clay soils in the 98043 zip code expand and contract with seasonal moisture changes, and that movement stresses any slab that does not have a properly compacted gravel base beneath it. Driveways poured without adequate base depth or reinforcement will crack within a few years regardless of the concrete mix used. The fix is a full replacement with a base built to handle the soil conditions here.

Yes. Original entry stairs on postwar ranchers in Mountlake Terrace were often poured as simple unreinforced slabs that have heaved or cracked as the soil beneath them shifted. We remove the old stairs, prepare the base, and pour new concrete stairs that are formed and reinforced to stay stable. The finish can be broom, exposed aggregate, or stamped to match or update the home's exterior.

Broom finish is the most practical choice for patios in this area because it provides traction on a surface that stays damp for much of the year. Stamped and colored concrete is also a good option for homeowners who want a decorative look, as long as the base is prepared correctly to prevent cracking that would damage the pattern. We can walk through finish options based on your specific lot and drainage conditions.

Lower-elevation streets near Lake Ballinger have a higher water table, which keeps soil moisture elevated even during drier months. That persistent moisture accelerates base erosion under slabs and increases the risk of uneven settling. On these lots, we pay close attention to drainage slope and base depth to give the concrete the best chance of staying stable long-term.
