Overview

Markham's Builder Tip Issue No. 12, dated January 1, 2025 and updated to the 2024 Ontario Building Code, on excavations before footing concrete is placed, one of the City's housing tips. It quotes Articles 9.12.1.1. to 9.12.1.3., 9.12.2.1. and 9.12.4.1. on removing topsoil and organic matter, standing water, freezing, undisturbed soil and footings over sewer trenches. The Objective lists precautions for poor soils, puts a soil test at $250 to $500, and describes lining the excavation with about 600 mm of straw under a tarp.
