Repair of gypsum/lime ash floors

[overlander matt]

We have a number of lime ash floors, none if which are in a good state (cracks, surface wear and poor repairs) and are likely to need some attention in due course... From what I understand, if the floor needs to be relaid, there is no commercial source of aggregate (lime kiln ash in our case) for making a new floor. Our conservation officer suggested that the solid floor material could be crushed and recycled... This does not sound like an enjoyable activity on a number of levels and I wonder if anyone here has any experience with this type of floor or how you go about getting concrete crushed.

I suspect that I will try to reduce the wear and tear on these floors as much as I can by covering with ply and carpeting to keep them going.

Thanks,

Matt

Can't help with the floor I'm afraid. But it is possible to hire small crushers: https://www.jewson.co.uk/tool-hire/earth-moving/loaders/products/6724/mini-crusher/
Note - You will find much cheaper options for hire, Jewsons just happened to come out at the top of the list.

Thanks for your help Paul. I have looked into this type of crusher previously just to recycle a large amount of concrete as hardcore but it proved a bit costly. In terms of the lime ash/gypsum floor, I suspect that the aggregate size will be a bit too large to use for my intended purpose. Ideally it might be easier to take it to a facility that could crush it - we have a few quarries in our area but I have no idea how they would respond to this type of request!

Thanks again,

Matt
