In a structural construction, concrete is the most resilient and long lasting construction material one can use. From concrete foundations to concrete works of various types (porches, steps, slabs, etc...).
Here are a few key notes to keep in mind:
- The internal strength of concrete is measured in MegaPascals or MPA. The more units of MPA, the stronger are the stress resistance of the concrete fabrication. Quality concrete footings & walls should be a minimum of: 25 MPA; slabs, steps & porches: 30 MPA.
- Supporting structures of concrete absolutely need to be reinforced by metal rebar in order to pass through the test of time. The amount of metal rebar necessary is determined by cubic mass and square footage coverage. House and home additions foundations must have rebar in the foundation footing and the foundation wall.
