Rock & Concrete Demolition Patterns

For proper application of Bustar expansive grout, determine the necessary hole pattern based on the specifics of your non-explosive demolition project:

  • Concrete Demolition
  • Selective Demolition
  • Rock Demolition
  • Boulder Breaking or Concrete Splitting
  • Silent Demolition
  • Bustar works for a variety of situations where explosives are prohibited or undesirable.

    DTI rock breaking chemicals provide non-explosive demolition solutions for rock wall demolition and wall modification in an existing structure, selective demolition in a hospital facility, concrete splitter work for beam modification, rock-centric quarry or boulder breaker objectives, for example, require careful hole pattern implementation according to strict design control.

    Design Control

    Factors that maximize Bustar expansive grout performance:

    • Hole Diameter
    • Hole Depth and Spacing
    • The larger the hole diameter the greater the depth the further the spacing.
    • The smaller the hole diameter the shallower the hole the closer the spacing.

    Quality Controls

    • Hole cleaning: The hole must be blown clean of water and drill cutting debris.
    • Water temperature, must be correct:
    • Water volume: 3L per 22 pound bag, 7.5L per 55 pound bag. Must be accurately proportioned.
    • Mixing Disciplines: correct volume of water, to the correct portion of Bustar chemical demolition agent - see instructions
    • Bustar Controlled Demolition Safety Controls
