Common Mistakes Made When Laying Concrete

You may think that there is not much to laying concrete, but it is not as simple as it looks. There is a lot of preparation needed before a drop of concrete is poured.

  1. Pouring concrete in the wrong weather conditions

Optimal time for pouring concrete is a warm and dry day. It is not always easy to wait for one of these in the UK! This is important because the temperature of the concrete during the first two days determines whether the full potential of the concrete’s strength is reached or not. If frozen, it weakens it greatly. Too hot and the water evaporates too quickly. Curing concrete means it must remain wet for a few days, so if it gets too hot, you may want to place sprinklers on it.
