Can I Lay Concrete In The Rain?
Tips to minimise damage
Concreting in the rain
As a nation we famously talk about the weather, that’s one of the joys of living and working within the UK. So the question is, can you lay concrete in the rain?
Water is a key ingredient of concrete production as it causes the hardening of concrete through a process called hydration. This is the chemical reaction between the water and the major compounds in cement which bond the two together.
However, too much water or a rainy day can compromise the finish cosmetically but more importantly the strength of your concrete.
Do we pour concrete in Wolverhampton when it’s raining?
It is never advised to pour ready mixed concrete in the rain but sometimes this is unavoidable. We will outline the risks of laying concrete in the rain and how to minimise the damage it could cause.
Signs concrete has been damaged
Cracking – When excess water evaporates from the concrete, this is called shrinkage. Cracks can appear on the surface but may be deep within the concrete too.
Dusting – The surface of the concrete is powdery or dusty to an excessive level.
Scaling – The surface layer may peel or flake off.
Once the concrete has completed cured, rainfall will not cause any damage. This is not the case when you are laying the concrete as the rain will alter the ratio between the components. The rain can also affect the appearance of the concrete which should have a smooth finish.
From around 6 hours after the concrete pour, the rain will not have as much effect.
How do you minimise damage?
Check the weather forecast. We know that this is never 100% accurate, but it can give you a rough indication. Total Concrete & Screed is very flexible with your booking. We can rearrange your concrete delivery to another time or day.
Observe the area. Make sure there are no downspouts leading the the concrete pad. For now, block them off or relocate them. Unblock any guttering around the outside of the house, they may overflow and pour water onto freshly laid concrete.
We always recommend keeping a plastic sheet close by when concreting. Not only will this sheet protect against the rain, it will also protect the concrete against wind and direct sun exposure.
If you were too late and your concrete is now soaked, do not mix the water into the concrete. Simply move the excess water away from the surface. Using something as simple as a hosepipe is ideal to not disrupt the finish of the concrete.
