If you’ve worked with ready mix concrete before, you’ve probably found out that it doesn’t always behave exactly how you expect. Most problems you’ll encounter aren’t hard to put right though – you just need to spot what’s going wrong early on and make the necessary adjustments.
Setting too quickly
This can happen in warm weather or if you don’t get it poured as soon as it’s delivered. It’ll become stiff and harder to move. You can avoid this by getting everything ready before it arrives.
Too wet or too dry
Don’t make it too wet or it’ll lose strength. If you make it too dry, it’s tough to spread. When you order concrete Swindon, check the mix is suited to your job before you start.
Cracking after setting
You get surface cracks when concrete dries too quickly on windy or warm days. You need to lightly cover the surface or dampen it so it cures more evenly.
Uneven or rough finish
A rough finish is usually down to timing. Don’t be tempted to smooth too early while water’s still rising, or the surface will weaken. Wait until it settles before finishing.
Delivery or timing issues
Delays can affect how workable the mix is when it arrives. Using reliable suppliers helps, and specialists such as www.monstermixconcrete.co.uk/concrete-swindon will give you a clearer idea of local delivery expectations.
Poor strength
If you add too much water or don’t give it enough time to cure properly, you’ll end up with weak or dusty concrete.
