Thread: About treated timber

Treated hardwood probably not, treated pine possibly, it’s always best to assume not and treat cut surfaces. I would coat it liberally with CN timber oil

Like this 35x70x600 long

Can you reverse the cut, so that the cut face is upwards? Then treat that face yourself with a preservative so that the original H4 face is on the ground and you should get much better and longer lasting protection than applying an aftermarket preservative to a cut face on the ground.

Not without buying a much wider timber and then there'd be more wastage.
I'm now wondering if I should just expect to replace the timber every few years or remake the ramps using gal steel angle underneath.
The decking timber on top is still ok.

I'd leave the H4 timbers uncut and dig out trenches in the ground to receive them.

Get wider timber, for example, 140 x 35 x 600, then rip it diagonally corner to corner, treat cut with preservative if you so desire, then screw decking to retreated cut side.

No wastage at all then.

Skip the timber and pour some concrete. For that small amount, you could do it in sections having mixed it in a wheelbarrow.

All good ideas. Thanks
I'll now ponder my next move.

Depending on the width and angle you need for the ramps, could you use something like this? Kerb Ramp Rubber | Enforcer Group

Thanks but nah it's too small

Now I see a photo of the problem, I would concrete a ramp. It's simple and durable. Otherwise as was offered before, don't cut the wood but dig a trench to receive them.
