  4. Demolition methods of structures Demolition craft tools Mechanical Demolition: -compressed hammers -hydraulic demolition -electric demolition -combustion engine based demolition -Water jetting

  5. Water jetting *concrete removal and rust removal can be made in one working step without any other additional means *slightly or not at all micro-cracking in concrete *Good bonding surface/base for new casting or shotcreting *Remove deteriorated concrete *Cause less noise than jackhammers http://www.falch.com/fr/entree-dans-le-glossaire/glossary/-c71f50a9ab.html

  6. Water jetting Ref. www.suomenvesipiikkaus.fi http://www.falch.com/en/products/robotics.html Water jetting robot for concrete renovation

  7. Drilling hammer drilling Cylinderic drilling with diamond drill -diamond blade 20-1200 mm Cutting Diamond Cutting (electric and hydraulic based - diamond blade 200-1500 mm, structural dimensions max. 650 mm - vault saw i.e. floor Saw -wall saw -chain and cable saw

  8. Melting Surgery i.e. pacing with oxygen -Concrete will be melted and concrete drains away -Melting temperature of concrete 1200-1500 °C Concrete will be deteriorated due to heat into the depth of 20 mm which has to be removed with another kind of demolition methods

  9. Breaking methods Compressive breaking murtovoiman Mechanical splitting Splitting with the expansion agent Explosion

  10. Miling methods Groove milling -parallel diamond cutting blade Level milling - asphalt milling cutter

  11. Surface Cleaning Methods Blast cleaning Brushing flame High-pressure washing -12-25 MPa vacuum out

  12. Demolition with pneumatic lifting bags

  13. To demolish entire element or part of structure Is mainly based on fastening methods of structures
