Does anyone have experience of putting anti-slip grooves into worn
concrete? The problem is in a livery stables with aisles about six feet
wide between the boxes. I'm told they had grooves ground in a few
decades ago. I can find machines on the web that would be suitable for
extended areas like a cattle yard but these would only be able to do
longitudinal grooves here, and you need transverse ones. It seems to me
that diamond disks used in either a normal or a large angle grinder
would be too narrow.

I doubt if "industrial" epoxy paint would stand up to shod horses.

The problem has come to light after removal of rubber matting which had
become badly split and torn. Replacement matting is obviously another
option, but I'm not sure the owner would stump up.

Given the cost of keeping horses, I think the owner needs
to get his priorities right.

You can hire machines like drum sanders that have a diamond
barrel, and are used for reducing the height of a concrete
slab. Whether it would leave a suitably rough surface is
another issue.

Or get an angle grinder, some ear protection and a diamond
grinding attachment and make some channels in a series
of sweeping arcs.

I've never done this, but how about a layer of concrete on top, and make
grooves in it whilst it's still soft? Using a rake, perhaps?

It's a commercial business, the owner only keeps a couple of horses
there and they are not really affected.

I don't think you want a smooth surface

This was the sort of thing I was thinking about. I was looking for
someone who had actually tried it.

But the observations are appreciated.

Trouble is the aisle is between two rows of stables and serves as the
drainage route, so you don't want to increase the level.

I've no experience on this. But I did something a bit related once: making a shallow narrow groove with an SDS by holding it at a fair angle & letting it bounce slowly along the surface. The resulting channels were quite uneven, but might reduce the amount of angel grinding required. Or perhaps one could sds it oversize & put a layer of epoxy in to even the bottom of the slot.

I suppose what you're left with is ground angel dust.

Just running a scarifier lightly over it can break up that slick greasy
surface that tends to build up on untreated concrete, and leave a rough
surface rather than grooves. The problem with that is that it's maybe
an hour's work but hire for a day is something like £300.

You're going to have trouble bonding that to the original concrete -
it's at risk of delaminating.

An easier solution might be to put down some epoxy floor paint (after
jetwashing the concrete until it's bright) and applying sand - or mixing
in sand???

I didn't pay anything like that when I hired a tungsten flail concrete
scarifier. In fact, given how it scratched up my floor I'd say it was
worth a try.

It would need to be full slab thickness - another 3-4".

Diamond disc wall chaser set on "shallow"?

You mean the two disk type? Will the inset bit come out readily? Perhaps
if you can set the disks up so that the "gap" bit is (say) around 5 mm
it will come out easily with a manual or SDS chisel. It's another good
thought.

You can swap the discs around to get a double disc - I did that when
cutting wide groves to take some stitching across a crack in the floor
screed. Works OK IME.

Thanks. I suspect that it will be a fairly strong concrete mix. I might
make a trial cut with one of my existing angle grinders to see what the
removal rate might be like before investing in a chaser. Actually there
are a couple on eBay at the moment. (I'm not expecting to need a chaser
for anything else, now).

On mine there are a series of spacers (probably about 4mm each that can
be positioned in any order with the discs at any position including side
by side... you could add more discs as well if you wanted, so say 3 or 4
discs side by side would give a 1/4" wide slot.

a double grinding disc would get 12mm, maybe a fraction more

Remember if its noisy, you have to remove the horses well away before its
done, or you will have a lot of annoyed owners at the very least.

Drill a series of holes, then buy a large quantity of magnets on eBay and
drop em in the holes,may have to experiment for the optimum amount of

You'd have to glue the magnets in, or they'd get attached to the horses
feet.
