Supplies for Demolition

A demolition hammer is chosen according to the thickness of the structure and the hardness of the material. For thin masonry or floors a light model is enough. For reinforced concrete structures you need larger power packs and suitable bits. The power pack, i.e. the part that produces the blows, must be matched to the hammer. Check the weight and the declared vibration values before buying.

A flat chisel is used to remove plaster and bricks, while a pointed or electrician's chisel is used to cut chases in walls for cables and pipes. A tile chisel lifts tiles without damaging the substrate. Chrome-vanadium steel chisels are suitable for masonry and brick, while those with a carbide insert work better on concrete. Always wear safety glasses and gloves.

The club hammer is the basic tool for striking chisels and points. Choose the weight according to the force you need to apply and the length of the job: weights that are too heavy tire you out and increase the risk of missed blows. Check that the handle is intact, without cracks, and firmly fixed to the head. Do not use hammers with a deformed or chipped head.

Masonry bits are used on brick and concrete, while electrician's bits are for drilling and marking in softer materials. Chrome-vanadium steel bits suit masonry. Re-sharpenable bits let you restore the edge several times, whereas replaceable ones are thrown away when worn. Choose the diameter according to the wall plug and always wear eye protection.

A nail puller is used to draw nails out of timber, formwork and frames in a controlled way. The set with carbide tips is designed for tougher nails. Place the head under the nail, use a small support as a fulcrum and protect the wood with a spacer if needed. Wear gloves and safety glasses, because the nail can spring out suddenly.

Rubble sacks are used to collect debris and rubble in an orderly way and to separate it for disposal. When demolishing in dusty conditions you need respiratory protection, safety glasses and ear defenders, as well as wetting the material while breaking it. Concrete and masonry dust can contain crystalline silica, so Italian Legislative Decree 81/2008 on workplace safety requires risk-reduction measures.

Diamond blades cut concrete, stone and masonry, while abrasive cutting discs work better on metals. SDS MAX bits are used with high-power hammers to drill heavy structures. Choose the blade according to the material and the maximum speed indicated on the machine. Dry cutting produces a lot of dust: use extraction or water and suitable respiratory protection.
