If you have heavy inert (soil, sand, shingle, hardcore, bricks, concrete) materials, the biggest skip you will be able to use would be a 6 - 8 yard, although this will also depend on the company and the size of lorries that they are using. Larger skips such as 12 or 14 yard maxi skips must be used for light weight only (light bulky waste) as they can become too heavy for the skip lorry to pick up once it has been loaded or may cause damage the driveway, pavement or road. There is a simple rule of thumb guide to knowing how much soil or hardcore your skip will accommodate. Try to remember that your skip will take roughly the same amount of tonnage as it will yardage. Therefore, a 4 yard skip will hold 4 tonnes worth of soil.
