It is therefore essential to ensure that you use the right proportions of construction materials in case you want to put up a concrete roof. You also need to ensure that the weight of the concrete is supported. Concrete roofing requires a lot of planning and herein is a step by step guide on how to construct the perfect flat concrete roof.
Safety and tools
Place the steel joists
After the selection of a particular size of concrete blocks, you will need to place the steel joists which should rest on a beam for support. The steel joists should also be proportional to the size of your concrete blocks. The joists are basically to provide a foundation for the concrete blocks.
Lay the concrete slabs
After making sure that your steel joists are laid, you need to place the concrete slabs one at a time and according to the size that you made from the steel joists.
Grooves and reinforcing bars
The next process after laying your concrete slabs is to trace the grooves, which are usually evident then place the W1.7 wire or even your preferred wire on the grooves then carefully bend then at the end of each slab. The spaces left between the slabs and the joists should have reinforcing bars inserted in them.
Preparing and pouring the grout
Once you are certain that your slabs are firm and have been held in position, you then need to prepare your grout. In preparing the grout, you will need to mix sand, cement, and water and once you have thoroughly mixed it, you can then proceed to pour it on top of the slabs gently. As you pour the grout, wait for the concrete to absorb it then spread it using a squeegee slowly. Once the top has been gotten moisture, you can proceed to add more grout, wait for it to dry as you pour water to prevent it from cracking.
