Concrete Fundamentals
- Concrete is commonly used in construction for:
- Columns
- Pier footings
- Foundation walls
- Interior concrete slabs
- Exterior concrete slabs
- Driveways
- Sidewalks
- Patios
- Garage floors
- Concrete strength is measured in mega Pascals (MPA).
- Minimum strength for footings and foundation walls is 15 MPA
- Minimum strength for interior concrete slabs is 20 MPA
- Minimum strength for exterior slabs, driveways, sidewalks, porches, patios, and garage floors is 32 MPA.
-
The Four Basic Materials:
- Cement
- Sand
- Aggregate
- Water
- The concrete mix is made up of roughly:
- 10% cement
- 20% air and water
- 30% sand
- 40% gravel
- This is called the 10-20-30-40 rule, but proportions may vary depending on the type of cement and other factors.
- Materials are mixed together based on volume
Concrete Placement
- Concrete should always be placed in forms to ensure clean, straight edges.
- Concrete should not be dropped over a distance of 8’ (2.4m) due to the risk of segregation of materials.
- Concrete should be spread and then leveled.
Concrete Finishing
- Use steel trowels for smooth concrete finishes
- Use aluminum-magnesium trowels for textured concrete finishes.
Foundation Preparation
- Concrete block foundation walls need to be parged with at least 6 mm (1⁄4 in.) of Portland cement plaster, forming a cove on the outside perimeter joint between the footings and the wall.
- Concrete foundations walls need the form tie holes plugged with tar or hydraulic cement.
Foundation Dampproofing & Waterproofing
- Dampproofing is required for all foundation walls that are part of a basement
- Used to control water vapour and soil moisture
- Waterproofing is required only for foundations that are subject to hydrostatic pressures
- Stops the influx of liquid water from passing through the foundation wall
- Dampproofing types include:
- Heavy coat bituminous material (rolled, brushed, or sprayed tar)
- Sheet material
- Self-adhering membrane
Foundation Drainage
- Drainage should always slope to direct water away from the building.
- 4” perforated tile is installed on the outside of the footing on firm soil to help carry excess water away from the foundation.
- 6” minimum of clear gravel should cover the drainage tile, acting as a filter.
- Drainage tiles drain into a sump pit or storm sewers at the road.
- In areas of very wet sites, drainage tile is installed along the inside of the footing and possibly laterally under the slab to prevent hydrostatic pressures.
Backfilling
- Backfilling foundation walls should not be carried out until the floor joists and subfloor are in place.
Engineered Wood Products (EWP)
- EWP’s range includes derivative wood products manufactured by binding or fixing strands, particles, fibers, veneers, or boards of wood with adhesives or other methods of fixation.
- This creates a composite material.
