Digging and Excavation
Digging and excavation form the next crucial step, primarily reliant on labor costs:
- Labor: R12,000 – R25,000
Binding
Once the site is prepared, the concrete work commences. Here’s a breakdown of the estimated costs:
- Cement (10 to 12 bags): R3150 – R4000
- Sand (20 tons): R8500 – R10,000
- Granite (20 tons): R10,000 – R12,000
- Labor: R25,000 – R35,000
Estimated Total: R250,000 – R320,000
Laying Foundation Blocks
After the concrete work, the focus shifts to laying foundation blocks:
- Cement (12 to 14 bags): R3750 – R4000
- Vibrated Blocks (about 650 pieces): R13,000 – R15,000
- Plumbing work: R2500 – R3500
- Labor: R35,000 – R45,000
Filling and Foundation Casting
Completing the foundation involves filling and casting, along with preparing for additional features like a soak-away and septic tank:
- Laterite (about 3 trips of 20 – 22 tons): R6500 – R8000
- Cement (25 bags): R7500 – R8500
- Nylon: R1500 – R2000
