The foundation would be eight inches of pure concrete, and I would also put in rebars facing upwards in the concrete, and then I'll place the cinder blocks. After the cinder blocks and the foundation are ready, I can start laying in the bricks. -

QuestionWhat foundation is good to use with black soil?
Community AnswerYou should never build or lay concrete on any soil. Soil is a living material, with living microbes constantly living and dying, and thus creating gases and chemicals that will eventually blow and crack your concrete slab or raft. Always remove all soil down to a hard inert surface, such as firm dry clay or rock.

QuestionWhat is the standard thickness for concrete?
Community AnswerIt depends on what you are constructing. If you are constructing a slab, the minimum thickness of concrete slab is 100 mm but the preferred thickness is 150 mm. The thickness (dimensions) of reinforced concrete columns and beams varies as it depends upon the load a building is designed to carry. The Plain Cement Concrete laid before laying the foundation is usually 75 mm.

QuestionAt several locations around the house foundation, there are circular concrete caps embedded. One cap split and fell away. I'm not sure of the purpose. How do I fix them?
Community AnswerThese concrete caps are to allow surplus water to drain out of the concrete and stop damp from entering the wall. They are made so that the excess water will permeate the cap or tube, and then take the easiest route out to the outside air.
