Our Tip: When Constructing on Bedrock, Footings Must Be Pinned
Concrete footings are strips of structural concrete that are poured for the foundation walls to be constructed upon. More often than not in Haliburton County we find ourselves building on bedrock, which poses a challenge for the proper fitting of the forms. If they are not pinned, the footings may slide on the rock and fail to provide proper support for the foundation.
Before pinning the footings, the rock surface must be thoroughly cleaned and swept. The footings are then pinned by drilling holes in the rock and inserting rebar pieces into the holes.
In Haliburton County, an acceptable footing size is 8” thick by 20” wide, depending on the structure. This will be determined and confirmed by your licensed building plan designer before construction begins.
