Ready-mixed concrete is one of the more versatile building materials readily available to the Do-It-Yourselfer. It’s a vital ingredient of many building projects, in the form of strip or raft foundations set within the ground to support walls and other structures.We get more info on concrete patio builder. It’s also a building material in its own right, and can be used to produce lots of outdoor features including patios, paths and drives.
In principle, laying concrete in the form of a patio, path or drive is the same as casting a slab foundation. Having said that, you’ll find many particular points to bear in mind over and above the straightforward casting technique:
First, order all of the ready-mixed concrete you need for the job in one delivery. When you use various batches of concrete for a big project, slight differences in shade will likely occur, which are impossible to correct.
You may wish to create shapes rather more elaborate than straightforward rectangles and squares. Fortunately, concrete can do this easily so long as you’re prepared to invest some time setting out the formwork in the shape you need.
As you plan the layout of your work, watch out for obstacles for example manhole covers and drainage gullies. You’ll want to plan the levels of your new surfaces carefully unless you are willing to move or reposition the obstacle.
Division of region:
Large areas of concrete can’t be laid as continuous slabs, or they will crack due to expansion and contraction. This means dividing the work up into bays, each separated from its neighbour by an expansion point of hardboard or bituminous felt if the concrete is laid as a continuous operation. If it is laid in alternate bays, board or felt points aren’t needed; a simple butt joint will suffice.
