Old timber edgings - tarmac drive - Removing old timber edgings from a drive

[stephenandwendy]

We have a tarmac drive which we would like to extend using gravel. We will be selling the house soon and so don't want to spend much money.

I have a load of old bricks and broken slabs that I want to use as sub-base. I have removed the old staked timber frames from the tarmac as there was a lot of vegetation and the timber was rotten after 12 years. Do I need to replace the timber with new gravel board timber edgings or can it just be left now? The tarmac will be extended using gravel over 25mm sharp sand over 4 inches of sub base material and the gravel will finish a couple of mm below the level of the tarmac. The gravel will be used for occasional vehicular standing. Any advice gratefully received.

if your selling it needs to look reasonable? you would have to break the slabs/ bricks down to about 40 ml. you could fill the voids in the sub base with sand but you shouldn't use it as a base for the shingle. the timber edge may need replacing as the tarmac will start to erode at the edge. leave yourself 20 to 40 ml for gravel.

Gravel driveway extension - oh how I would look forward to the spillover onto the tarmac!

Still, it's got to fit the job....if you are selling soon.

The tar will require some edging to stop it crumbling away when trafficked over - how long is the proposed joint?
