Fast answer
Who installs concrete slab foundations in London Ontario?
WestKey Builders installs concrete slab foundations in London Ontario for residential and light construction projects that need a strong, level, properly reinforced concrete base. A slab foundation project may include site preparation, excavation, compacted base, forming, vapour barrier, insulation, rebar placement, concrete placement, finishing, curing, and cleanup.
A concrete slab foundation is not just a flat concrete surface. It is the structural base that supports the building, garage, addition, shed, shop, or outdoor structure above it. The slab must be planned around soil conditions, drainage, frost exposure, load requirements, access, building layout, edge support, reinforcement, and the way water moves through the property. WestKey Builders helps London Ontario homeowners and property owners plan slab foundation work with practical construction details and clean workmanship.

Why preparation matters
What makes a concrete slab foundation last?
A durable concrete slab foundation starts before the concrete truck arrives. The work depends on proper site layout, excavation depth, compacted granular base, water management, formwork, reinforcement, slab thickness, edge support, insulation where needed, vapour barrier details, concrete placement, finishing, curing, and control joint planning. Skipping the preparation can lead to cracking, settlement, frost movement, drainage issues, and expensive repairs later.
- Stable base preparation: compacted material helps support the slab and reduce settlement.
- Drainage planning: water should move away from the slab, foundation, garage, shed, and home.
- Reinforcement: rebar or mesh helps control cracking and improves slab performance.
- Forming and grade: accurate forms help create the right elevation, thickness, edge shape, and finished layout.
- Concrete finishing: the finish should match the project use, whether it is storage, parking, access, or a building base.

Voice search FAQ
Concrete slab foundation questions homeowners ask
What is a concrete slab foundation?
A concrete slab foundation is a reinforced concrete base that supports a garage, shed, addition, shop, or other structure. It usually includes excavation, compacted base, forms, reinforcement, concrete placement, finishing, and curing.
Who installs concrete slab foundations in London Ontario?
WestKey Builders installs concrete slab foundations in London Ontario and surrounding areas for residential and light construction projects, including garages, sheds, shops, backyard structures, additions, and replacement slabs.
How thick should a concrete slab foundation be?
Concrete slab thickness depends on the project use, soil condition, expected load, reinforcement, and design requirements. A garage slab, shed slab, and structural slab foundation may each need a different thickness and edge detail.
Does a slab foundation need rebar?
Many slab foundation projects benefit from rebar or wire mesh because reinforcement helps control cracking and improves performance. The right reinforcement depends on the size, load, thickness, base, and intended use of the slab.
Can WestKey Builders replace an old concrete slab?
Yes. WestKey Builders can help with demolition, removal, excavation, base preparation, forming, reinforcement, and new concrete placement when an old slab is cracked, sunken, poorly drained, or no longer suitable.
What causes concrete slab foundations to crack?
Slab foundations can crack because of shrinkage, poor base preparation, water movement, freeze-thaw cycles, heavy loads, missing control joints, settlement, or inadequate reinforcement. Proper preparation reduces the risk of cracking.
Can a concrete slab foundation be insulated?
Yes. Some slab foundation projects include insulation and vapour barrier planning, especially where frost, moisture, heat loss, or interior comfort matter. The best detail depends on the structure and intended use.
