Whats the most cost effective product when raising ground levels?

Hi Guys

Our site slopes down away from the lane towards our house by about 90cm over 8 metres. Each side is also about 8 metres wide.

So i have a wedge shape on either side of the central drive that i need to fill. Not certain if it needs to also be SUDs compliant.

Filling it 100%with topsoil will probably be more expensive than necessary.

If anyone has done similar how did you approach this please?

How much do you need to fill? Have you dug out for your foundations yet? You can fill with whatever you dig out and cap with topsoil

local builders will probably be happy to fill your holes with rubble for free...Help with Suds as well.

Each side is about 8 metres by 8 metres. Then the depth/height is 900mm tapering to zero, hence me saying a wedge shape.

House is built and occupied. Soil from the foundations is required elsewhere.

Well you're not going to fill that deep in topsoil. Either hardcore or some inert fill. Are you parking on it or is it just planting/garden? If you had a trustworthy grab driver who you knew they could lose some loads on your job. Wouldn't want any old rubbish though.

8M by 8M by 0.45M is the volume you have to fill, so 28.8 M³ per side.

 

So you either scrape off the top soil, add the infill then replace top soil, or for less work put a lesser amount of infil then fresh topsoil on top.
