Wedge tool is a simple tool, the product material is wood, metal or other materials, a thick end and thin edge, drive between two objects or object parts to fix or separate them, by applying force on the wide end, split, lift or tighten the object, make the narrow end push or separate material.

To use a wedge in floor work, a small and thin object is inserted into a gap between two flooring materials, such as tiles or wooden planks. The wedge is then driven further into the gap by applying force with a hammer or another tool. As the wedge is pushed deeper, it creates pressure and forces the flooring materials apart, creating a gap.

Wedges can be used for various purposes in flooring work. They can help level uneven flooring by lifting certain areas, or they can create expansion joints to allow for natural movement of the floor materials. They can also be used to separate damaged or old flooring for removal and replacement.
