Diy Concrete Steps
DIY concrete steps can be made in several different ways. You can make DIY concrete steps by casting the concrete in situ, which means on site, mixing and placing it within formwork, or you can make DIY concrete steps by using concrete bricks or blocks to build the steps and then filling in with concrete (also mixed in situ) behind the building units.
If you use concrete bricks to build steps, you will follow exactly the same process as you would if you were to use clay bricks. So in this article we are going to focus on casting them in situ using blocks or formwork (which is also called shuttering) to make them.
Basically when you use concrete - which is a relatively precise mixture of cement, building sand and stone mixed with water - for building, you need something to keep the mixture in place while it hardens and cures. So, if you think about the shape of the structure you are planning to build, you can see that it will need to be, quite simply, stepped. The number you build will depend on the height of the slope or distance you need to cover, and you can use blocks or formwork to define the profile of the structure.
DIY Concrete Steps Foundation
Remember you will need a concrete foundation for brickwork or blockwork. A 1:4:4 (cement:sand:stone) mix is perfect and you can use a 1:6 mortar mix to lay the blocks. You will need some sort of timber or steel for formwork, and you will need to assemble it securely before you mix your concrete. Before you do this, to save money, in the profile you have constructed with broken bricks and sand to fill the voids, and compact it well. You only need to leave a few centimetres above this material for the concrete. After you have done this, mix the rest of your cement, sand, stone (1:4:4) and water together, using just enough water to make a soft mix that isn't at all runny. Shovel it on top of the material you compacted, and leave it to set and cure. After a few days you should plaster the blocks and upper concrete surface. If you used formwork, wait a few days before you remove it to see how your steps have formed the shape you designed.
Whichever building process you use, you will need to measure the area to be covered and make sure that treads and risers work for those who will be using them. If a tread is too high or a riser too narrow, they won't be user friendly. A steep structure is not a good idea in that garden and there are quite strict guidelines in terms of dimensions for those built inside houses.
The only other really important factors to remember are that the concrete needs to be mixed correctly and it must also be well compacted and levelled out for your DIY concrete steps.
