Hi all

I need to shore up the boundary between my garden and next door due to
different soil levels.

There is a gravel board left over from a previous fencing project which
looks useful for the job.
The board is of the plain concrete variety with one smooth (face) side and
one gravelly. This is not the type with cast ribs, just a constant
thickness of concrete.

What does the group recommend for cutting this to length?
I don't have a stil saw.
As the whole board will be buried, the finish at the end of the cut isn't
too important.

Tools that are available and spring to mind are:

The ubiquitous angle grinder with stone disk - can I use this for cutting,
or are the stone disks specifically for smoothing? (This is a small hand
held jobby so I doubt if any cutting attempt will go through the full
thickness of the board)

SDS drill used to either chain drill holes or with chisel and rotary stop.


TIA


Phil

You can buy stone 'cutting' discs easily. No, it won't cut right
through, cut a line from each side & it should break along that line.
May have rebar inside, so switch to a metal cutting disc.

Likely to shatter it.

A stone cutting disc will work. If there is no reinforcing, scoring all
round to about 0.5cm deep will usually allow it to be snapped cleanly -
otherwise, cut right through.

Angle grinder!

Even a 4.5" with *cutting* disc should cut 1" deep. Expect steel
reinforcement. Cut both sides and snap remainder.

Stone cutting grit disc (1-2mm) is fine - but a thicker stone grinding
disc (6mm) would take ages.

IME it may take a whole pack of discs, but they're cheap enough

Much better to buy a cheap diamond disc for a few quid. Faster, safer,
cheaper per cut.

Less than a fiver for a pack of 10

Thats what I did when I cut one. The larger angle grinder would have done
better had it not been on loan.
