When using ready-mix concrete, time is of the essence, as is careful planning, to ensure the best results. Even if it is a small area to be concreted, if it is not properly executed, it can lead to costly mistakes and delay the completion of a building project. Here are some of the most common mistakes to avoid when working with ready-mix concrete.

Insufficient Ground Preparation

It may seem time-consuming, but it’s vital to properly prepare your ground area for the concrete. This means levelling the base and packing it in the right way; otherwise the concrete is less likely to settle and could crack. It’s a good idea to put crushed stone underneath the base to allow for water drainage.

Check the Forecast

Heavy rain or extreme temperatures when pouring concrete can affect its performance and strength. The temperature of the concrete when delivered should not exceed 35°c, and hot weather will mean it dries too fast. Cold temperatures mean it will take too long to set, and the surface could be damaged. Always consider the weather before pouring concrete Stroud and delay if necessary.

The Right Mix

It’s vital to have the correct mix of water to cement, as the mix will be unworkable if it’s too dry and too weak if there is too much water. Ask a concrete supplier such as https://www.monstermixconcrete.co.uk/concrete-stroud/ for advice.

Support Structure

Using the right system of support is vital, as using fibres of steel mesh incorrectly will damage the overall structure. Make sure it is right for your load and for your soil conditions.

Placement of Joints

Joint areas need to be carefully prepared before the pour and correctly cut at the right time. If control joints are misaligned, the concrete can develop uncontrolled cracks, so make sure these are set 24-30 times more thickly than the slab before cutting them halfway through it.

Time to Cure

Allow plenty of time for the concrete to cure so it achieves optimum strength. The surface should be kept wet for seven days to stop cracks.
