We are at one with Gabriola

Brraaaa, brraaa, brraaa.

Not a new age mantra.

Rather, the incessant rattle of an industrial hammer drill.

When the machine arrived to excavate we knew our house site would be rocky. Once the excavator left I spent a week with a pick and shovel cleaning off the rock. The result was fractured post-glacial jumble beneath what will be our concrete stem wall and the 22 post piers of our foundations. Early on I suspected we’d hit bedrock so I asked our structural engineer Kris Dick at Building Alternatives for a foundation detail for our house plans that covered this scenario for our high seismic area.

So when we hit rock, the need for a massive 30 inch (76 cm) wide spread footing was out in lieu of 15mm rebar for our concrete stem wall being sunk a foot into the rock every 24 inches (60 cm) around the house perimeter plus four 15mm rebar dowels for each concrete pier.

Alas, holes don’t drill themselves. I promptly destroyed the first DIY grade hammer drill on hole number six so I rented an industrial beast and let the hard core vibrating begin.

Three days later I’d smashed 150 holes 12 inches (30cm) deep into bedrock to pin our house foundations to Gabriola.

Gabriola never stood a chance. We will be one.
