How It Works
- Request. You give your location, the service, the type of building and its rough size.
- Match. Your request goes to independent contractors suited to the job, with your permission.
- Site visit. Contractors contact you and, for larger jobs, inspect the site and drawings.
- Quote. You receive written prices, ideally on the same drawings and specification.
- Compare. You check scope, steel, concrete, exclusions, programme and payment terms side by side.
- Build. You hire the contractor you choose, or nobody. There is no obligation.
Share plans, engineer's drawings and soil reports with the contractor directly once you are in contact.
Common Projects
- New house. A raft or strip foundation and ground floor slab.
- Double-storey. Foundations, a first-floor slab and a staircase.
- Extension. New footings or a raft tied into the existing house.
- Garage or outbuilding. A garage slab or small raft.
- Sloping site. Excavation, retaining walls and stepped foundations.
- Commercial floor. A warehouse, workshop or yard slab.
Approvals and Compliance
- Building plans. New buildings and most structural work need municipal plan approval under the National Building Regulations.
- Soil report. A geotechnical investigation sets the site class and guides the foundation design.
- Engineer's design. Rafts, suspended slabs and higher retaining walls need a design by a registered engineer.
- NHBRC. New homes must be enrolled with the NHBRC before construction starts. Ask your builder for their registration.
- Inspections. The engineer and municipal inspector check trenches and steel before concrete is poured.

Request a QuoteWhat to Include in Your Request
- Your name, email and phone or WhatsApp number.
- Your town or suburb.

Availability
Availability depends on your area, the size of the job and how soon you need it. Contractors are independent and decide which projects they take on, so not every request can be matched. Most contractors want to see plans or the site before giving a firm price.
Comparing Contractors
Whoever you consider, compare like with like:
- Scope. Exactly what is included, from set-out to curing.
- Steel and concrete. Quantities and strength class against the engineer's drawings.
- Exclusions. Rock, fill, pumps, design fees and VAT.
- Programme. Start date and days on site.
- Payment terms. Deposit and progress payments.
- Track record. Recent projects and references you can contact.
Frequently Asked Questions
How does this service work?
You send one short request with your location, the service and the size of the project. Independent contractors suited to the job can contact you with availability and prices. You compare and choose, or hire nobody.
Are you a construction company?
No. We do not design or build foundations or slabs, and we do not employ building teams. Independent contractors and engineers quote and do the work.
How much does a raft foundation cost?
As a ballpark, R850 to R1,600 per m² for a single-storey house and R1,100 to R2,000 per m² for a double-storey, excluding VAT, design and soil reports.
Do I need a raft foundation?
Only if the soil and design call for one. A soil report and a registered engineer decide the foundation type for your site.
Do I need an engineer?
For raft foundations, suspended slabs, staircases and most retaining walls, yes. The engineer designs, inspects and signs off the work.
How many quotes should I compare?
Two or three written quotes based on the same drawings and specification are usually enough to see a fair price.
Raft Foundations South Africa is a quote-matching service. We do not design or build foundations or slabs, and we do not employ construction teams.
