Everything about an exterior slab here is decided by freeze-thaw and road salt. We pour an air-entrained mix specified for both, and cure it properly rather than finishing the surface and leaving.
Booking matters more in Barrie than further south. Concrete needs warm conditions to place and time to gain strength afterwards, so a pour late in the season is a worse pour. We would rather schedule you early than squeeze one in against the first freeze.
The Painswick, Ardagh and Holly builds are where most of the replacement work sits, and the driveways there are wide enough that joint spacing is a real decision rather than an afterthought.
In the older Allandale and Lakeshore lots the original surface comes out, the base gets rebuilt, and the forms go to the finished grade so the slab drains away from the house.
We handle concrete driveways across Barrie — including the Lakeshore, Allandale, Painswick, Ardagh, and Holly, and the streets and properties around Kempenfelt Bay, the Barrie waterfront, and Centennial Beach.
