Planning to Pour a Concrete Slab Planning to Pour a Concrete Slab

When you are planning to pour concrete slab sets, then you need to work out a design, and a course of action before you begin. The design of the concrete slabs is partially dependent upon the thickness of the slabs, and also by the ratio of earth to gravel. When you are ready to start installing your concrete slabs, consider where the installations should go, and lay down a few rules to positioning the perfect concrete slab. Checking the planning of your concrete slab before you begin to pour is vital to ensuring that you get the most out of any patio or pathway that you are creating.

Set a Level Space

When you are digging the hole in which your concrete slab will be poured, make sure that all of the angles are completely level, and that you have no excess lengths that will affect the final position of the slab. Make sure that the sides are even using a spirit level, and also check the angles. Check that the sides are the same depth at both the top and the bottom, and that the depth is the same all the way around. You should also ensure that the bottom is as level as the rest of the angles by using a compactor. This will hammer it down to a similar thickness across the board. Only after you have completed this can you be sure that the concrete slab will be the correct angle.

Check the Thickness

Calculating the thickness of the concrete slabs is another important element in planning to pour a concrete slab. You should be able to work out the thickness using an online calculator, and also work out the ratio of concrete to gravel being used on the ground. These elements are vital for finding out the right amount of concrete.

Work the Soil

The soil around your concrete needs to be perfect in order for you to have a good pour. Remove any organic material from the top of the soil, such as weeds and roots. Remove the large rocks which are near to the surface. If you have any problems, such as a frost the night before, then you need to add an extra thick layer of gravel beneath the ground area, and take it out to around a foot beyond the area planned for the slab.

Preparation

Before you begin to pour the slab, make sure that you have all the supplies you need, including wire mesh and grade stakes, and also something to protect you and the surrounding lawn from splash backs from the concrete. If you are adding a slab against a foundation, such as the house wall, then you will have to use a bond breaker to keep the new slab from combining with the foundation. In addition, use the bond breakers to keep each of the slabs separate as you pour.
