With the 14-foot foundation walls complete, our focus at the Camas Hilltop House has shifted to protecting the structure and setting up the systems that will power the home.

Waterproofing and Insulation

On the uphill side of the foundation, we applied a spray-on waterproofing coating, followed by dimple board to create drainage space, and rigid insulation where the wall abuts heated space. Together, these layers protect the structure from moisture and improve the home’s thermal performance.

Trenching, Backfill, and Compaction

We trenched for electrical and communication lines, including new power to the well. The original well wiring conflicted with excavation for the house, so relocating and upgrading was essential. Having water available on site also allowed us to properly compact the structural backfill – dry gravel this time of year tends to leave air pockets.

To ensure the backfill reached the desired level of compaction, we consulted with the geotechnical engineer. They were on site during backfilling to advise and perform testing. This confirmed that each lift of gravel was compacted to the required standard, setting up the site for long-term stability and making sure the concrete patios and walkways are poured over a solid base.

Planning for Power

This project will include an 800 amp electrical service, which required early coordination with both the utility company and the contractor running the primary service line. Together we determined the best route from the street to the transformer – a combination of line boring and trenching – to avoid conflicts with other site features.

Thinking Ahead

While these trenches are open, we’ve also included conduit for future needs, such as a driveway gate and connections to the existing shop building.

With the underground utilities and backfill in place, we can move into the framing phase where the house will really begin to take shape.
