Rather than dumping soil debris from your building site, invest in a Traserscreen unit to easily sift the topsoil from rubbish to reuse onsite. Not only are you doing your bit for the planet, but you(TM)re saving money on landfill fees and premium prices for topsoil to be trucked in by another contractor. A Traserscreen from Taunton Holdings is a mobile soil sieving machine that can be used onsite to effectively screen piles of waste material, including rock, gravel, sand and soil.
