Im having a new garden wall built and some pattern imprinted concrete done,now the idea was ro have it done in the spring but today hes rung up and spoke to the wife and they start tomorrow im just concerned with the temperature whats the coldest you can lay bricks and do this concrete thing thanks
4 and rising is usually the temp mate I think, unless I'm told differently. The batching plants won't send out or mix up if colder than at times but known it done. You can add an additive to it I think that allows colder temp when mixing up domestic stuff like yours. Note - not a brickie but do work in construction. Edit - just seen posted link and 2 degrees.... But I'm sure that's low. Will find out!
Givover would be a good person to talk too, but to put your mind at rest they have been working on new builds up the road through winter so can't see it being much of an issue for a wall
Agree 4 and rising which on a frosty night could be an 11 am start and 2 pm finish like the link says bricks must be dry and protected after work is complete .I would normally cover the work in hessian then some visqueen ( plastic sheet ) and the more hessian this is my preference as if you just vis queen the wall and the mortar is wet the vis queen will lay on the joints and Mark them but the vis queen over the hessian will keep the material dry in case of over night rain extra hessian over the vis queen may get wet if it rains but if it doesn't rain it gives extra frost protection and can easily be dried out. I would have more fear laying the printed concrete or any concrete as if it gets " Frosted " the face will powder up and all work will need to be broken up removed and be relayed which must not be at your risk! It's not like yard concrete which would stand a little rain its a finished article and once the face has been destroyed by frost it's over!
You can build a wall as long as it's above freezing but most brickies will use an anti-freeze additive then cover it with hessian sacking to stop the frost getting to it when temperature drops. I use this method when I'm cementing ridge tiles.
Think we just about dodged the bullet on this all walls up and laid the concrete this morning was touch n go though! Well pleased with the result though more brownie points earnt for when I tell her I want a XT/WR/SM for a bit of fun!
