Cutting Gravel Board

May 25, 2012 8 Replies

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

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.

Can I be first?

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.

Thanks to all - grinder it is!

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.
