Hi Guys.
I had my front "Lawn" (scabby bit of grass) Blocked Paved 5 years ago.
The ground is Heavy Clay.
I have a bit that appears to be Heaving. This area is next to a drain and where a Forsythia grow for 20 or 30 years.
The contractor who laid the paving came back last year and lifted the area and levelled it, no sign of any roots pushing up. But now the area is back up again. The area is about 2 meters x 2 meters and has rising about 50mm to 75mm in the middle, since last year.
Is it Heave and how long can I expect this continue?
