Below the arboretum.
Sehome wraps around the hill below the Sehome Arboretum, between downtown and Western, on sloped lots where a lot of the houses have daylight basements built into the grade. The homes run from the 1910s through the 1960s. When you put a basement wall into a hillside in a climate like ours, you create the exact conditions for foundation cracks and water intrusion, which is most of what we get called for here.
Our Sehome work is heavy on foundation crack injection where a basement wall has cracked under hillside pressure, retaining walls to hold the sloped yards and driveways, and drainage to keep water off the buried walls. The daylight-basement homes especially need the water managed, because a wall with living space behind it can't be allowed to leak. We inject the active cracks, reinforce where a wall is bowing, and drain the water at the footing.
Common home styles
1910s to 1960s homes on sloped lots, many with daylight basements, plus newer infill and student rentals near the WWU edge.
Soil and water
Hillside lots below the arboretum where water runs downhill through the soil all winter. That pressure on buried basement walls is what drives the crack injection, reinforcement, and drainage work here.
