Question from carl:

Hi, I need to work out the cost of a foundation.

The foundation is 1m deep x 500mm wide and is 6.3 meters long.

The cost per cubic meter for concrete is 1000 rand
escuvation of earth will be 100 rand per cubic meter and back filling wil also be
100 rand per cubic meter.

What will the cost be


You can use our volume calculator to calculate the volume. For the width use 0.5 meters.

Multiply the volume by 1000 to find the concrete cost in rand. For the excavation and backfilling costs you will need to estimate the volume of earth than needs to be removed and backfilled.
