M.P.A. An Explanation
Concrete is measured by its strength capacity. MPa (megapascals) is the metric measurement for psi or pounds per square inch. The BC Building Codes require a minimum MPa for specific concrete projects. Please refer to the table to choose the appropriate MPa when calculating your volume and price.
BC Building Code Recommended Strengths
- Footings, walls, foundations- 20-25mpa
- Interior flatwork – 25-28mpa
- Garages, carports – 32mpa
- Exterior flatwork – 32mpa
