Drilling, cutting, alteration, and demolition

The use of electrical or electro-hydraulic equipment and diamond cutting tools allows holes of different diameters to be made in reinforced concrete, as well as opening slabs and walls made of the same material, without vibration or noise.

The "thermal rod" method to perforate plain concrete and reinforced concrete through fusion can be beneficial in certain cases.

Apart from drilling and cutting concrete, Stap  also uses partial demolition techniques to modify existing structures in which specific conditions make the use of traditional methods impossible or inadvisable.
