Hi all,

I'm hoping someone can advise me on what to do regarding old foundations.
I'm planning on building a 10 x 6m workshop on the site of an existing 6 x 3m garage. The existing slab looks to be 6" deep on one side less on the other due to sloping ground.
What would you recommend I do with the old foundation slab?
Many thanks for any suggestions

professionally speaking break it out

cost wise you may chance shuttering round it and putting dowels into the slab but that would be a bodge

Do the job properly, break it up and start afresh.

being in Essex you may well find someone locally who can hire you a mini crusher, that way having removed the existing base you can reuse it as subase for the new. possibly saving on humping it around or the cost of disposal.

Hi guys,
Thank you your quick response. You've confirmed what I thought really, Looking for an easy route but not at the risk of structural problems.

Breaking up and Crushing on site sounds like a good idea, would you have any idea on a likely rough cost?


Many thanks for your help

Having called around today it's looking like the way forward is to hire a mini digger and hydraulic breaker.
Mini Crusher hire, next on the list.

many thanks

"Essex crusher hire"in goggle shows plenty of options. a day rate of £150-£200, but transportation costs can apply is the norm. it also depends on the quantity of material and the cost of disposal, as to whether it is viable purely from a cost point of view.

You only have 18m2 to break up so if it's 4-6" thick you'll only have 6 tons max to get rid of. That's a few hours with a jack hammer, barrow and a skip to me. Cheap as chip's. If you want to keep some for hardcore I usually chuck the big stuff and keep the small stuff.
