I am buying a house that I will demolish & replace with a new one. In
the garden, the existing lawn descends gently down to a nice
stream/river. But, between the upper parts of the lawn and the stream is
an area of 1,500 square meters that consists of soft wet ground. This
entire area is covered with Giant Hogweed and some clumps of tall
This area could look lovely if I could raise & clear the ground and
extend the lawn from the house down to the stream.
This is what I am thinking about doing, but would be grateful for any
comments or easier/cheaper suggestions...
1) Cut the stalks of the largest Hogweeds and lay flat. ( I am fully
aware about how dangerous this stuff is).
2) Lay 1,500 sqm of weed fabric over the entire area to keep out the
Hogweed and restrict the rubble fill from sinking into the mud..
3) Demolish the house and use the brick rubble to raise the lawn by
about 40cm and incorporate a French Drain system to the stream.
4) Lay another layer of weed fabric over the brick rubble.
5) Lay down 30cm of top soil
6) Seed for the lawn.
Am I going over the top here? I need to create a drain'able surface but
do I need so much fabric? I don't want to give the Hogweed a chance to
come up. Will the top soil remain in place over the weed fabric or could
it wash away?
