Our tarmac drive has two round depressions in it, about 18" across and a few
inches deep. I guess it's due to oil from previous houseoner's car but no
real ideawhy. It's not cracked or getting bigger and the rest is fine. House
is 10 years old..

I've tried to repair by putting the sort of tarmac you can buy in bags from
B+Q in , but I can't seal the edges, and because it slopes like a beach the
tarmac won't stay on the shallow edges. So I get a ditch that collects mud.

Is there any way to do this properly? Ideally like when they repair roads..

thanks
