i concreted my shed base back in september. anyway all has been fine a bit of plaster cracking when first poured but nowt realy. shed is 40' x 20' poured in 4 bays. anyway today i have noticed the 2 middle bays have a crack across them. on one it looks as though it has lifted by 5mm. when i poured i thought i would get away with the exspansion because theres nothing retaining the edges. the only thing i can think of is the ground underneeth has frozen. not bothered realy just a little peed off, good job its my own job.concrete is 6'' thick of good strengh. any thoughts.

It's always wise to put in crack control joints , especially on that length. Your garage floor is a disaster area, an accident waiting to happen. Have'nt you got a coshh storage area for your petrol containers, they look dodgy alongside your heaters, leccie cables etc: ???

brush neat cement into those cracks. that should seal them.
