Heavy duty blue rubble sacks in a very strong 540 gauge, suitable for builders, DIY and garden use. Supplied in a pack of 100 sacks. Rubble sacks are used to collect and carry waste such as rubble, offcuts, packaging and garden waste from a job, and a heavier gauge helps them cope with sharp or heavy items. Do not overfill the sack, as a sack that is too heavy to lift safely can split or cause injury, and take care with sharp edges. Dispose of waste in line with local rules. Choose a size and gauge that suit the weight and type of waste you are clearing.
