Long winded, but looking for some advice on the best way to sort out cracking on a concrete slabs on the farmyard.

Basically the majority of the concrete on the farm is fecked. All laid before my time, 4’’ thick.

Some sections have been renewed at 6’’ a good few years ago, but developing cracks on slab corners. I think it down to water getting down underneath the slab from all the broken 4” sections.

What is my best option to repair this and prevent these cracks and broken pieces from spreading
up the slab, until I can start replacing the existing broken up 4” concrete?

TIA.

You can’t. Those cracks really don’t seem that bad!

in time you just have to bite the bullet and replace. Mine is a patchwork of new and old, the pain is that they had a 3-4 inch pad which you can’t replace like for like so have to dig up the sodding lot and start over!

once it cracks they just seesaw back and forward,nothing will fix it permanently

Thanks for the reply.

The rest of the yards are a mess tbh, and it’s a pain in the hole trying to keep it clean.

Just trying to save the good stuff and prevent the cracking for as long as I can get away with.

Think I’ll go an dig those sections out and patch them up level again. Fire a few re-bars in the existing as well.

Similar concrete here and not on any base to speak of. Cement must have been cheap because it smashes up like glass.

Any quick repairs needed to prevent damage to cows feet during winter gets postcrete provided the hole has sharp enough edges to retain it. Others will get a mix with blue circle fast setting..... and it is fast setting so don't hang around. Find it bonds to old concrete fairly well but is still only a stop gap until we win the lottery.

Usually with 'grandad concrete' it is the sub base that lets it all down.

We have endless amounts of it and can tear up slabs with the digger bucket easily, many of them have tyre treads underneath that indicate that they were laid straight on the mud. Fine if you are driving a TED but not so good in a Manitou with a spreadabale on the front.

We are constantly doing the worst bits - square up edges with a diamond blade, dig out to 18 inches, pack with hardcore and 8 inches of concrete with mesh.

Tedious unfortunately.

If it was laid on compacted mud, it's fine until the concrete cracks and lets water get through.

Most of ours did 50 years useful service, can't argue with that!
