Garage floor

Aug 25, 2003 4 Replies

Evening all, I am about to concrete my garage floor.It is 4.4m x 6.6m and when it is finished it will have a 5 ton truck on it. Is 100mm of hard core / scalpings compacted down and then 100mm concrete with reinforcing mesh in it satisfactory for the weight ??

Hello Rich

I'd say yes, but for a more technical answer;

Are you laying this in two slabs,or one,the first would be my preference with expansion also are you building on the edge of the slab,if you are then make it thicker and wider at the edge something like 200 x 400 if it is a prefab type garage

Evening all, the garage is already built out of concrete blocks with a pitched roof so the floor needs finishing I was going to lay it in one piece as several friends have done this in the past and it seems to have worked for them. The internal dimensions are 4.4m X 6.6m why does it need to be in two bits, as if it was done in one I would be able to do the garage floor and the hard stand out side it in one 6 cubic meter lorry load of concrete!!!!

Hello Rich

expansion is usually put in on something this size to prevent cracking, but as it's undercover it's not going to be subject to such extremes of heat and expansion.

Even if you did decide to add an expansion strip (typically a 1/2" strip of wood) then you would still lay it in one load.
