Demolition

Environmentally friendly and safe.

Compared to conventional mechanical methods of demolition, explosives demolition is more cost competitive,
time efficient, safer, and environmentally friendly as it reduces noise, vibration, and dust.

Explosives Demolition

Explosives demolition is a method of demolishing buildings and structures by removing their pillars, walls, and other key structural elements
with a small amount of explosives, thereby reducing their structural stability, and leading them to collapse under their own weight.
As explosives demolition work takes only 5 to 15 seconds, it is the best method to minimize the inconveniences to the neighboring communities.

Collaps methods

  • Felling

    Possible to fell and collapse within the planned space by controlling felling direction

    Technically simple method

    Mainly used for such objects as chimney, elevated water tanks & power posts

    Sufficient space required in the felling direction

    Can be applied to limited space, especially in urban centers

    As the outer wall of a structure is pulled toward the center and collapsed,
    the surrounding space needed is minimized
