How We Works

Technical requirements of formwork:

  • Formwork should be of the desired shape, size and and fit at the location of the member in structure according to the drawings.
  • Formwork shall be carefully selected for required finish surface and linings to produce the desired concrete surface.
  • Formwork should withstand the pressure of fresh concrete and working loads and should not distort or deflect from their position during the concrete placing operation.
  • Formwork should support the designed loads any other applied loads during the construction period.
  • The formwork must not damage the concrete or themselves during  removal from structure.
  • Panels  of the formwork should be tightly connected to minimize gap at the formwork connection to prevent leakage of cement paste.

Functional requirements of formwork:

  • Form sections should be of the size that can be lifted and transported easily from one job site to another.
  • Formwork should be dismantled and moved as easily as possible so that construction of the building advances.
  • Formwork Units must be interchangeable so that they can be used for forming different members.
  • Formwork shall be designed such that it fits and fastens together with reasonable ease.
  • Forms should be simple to build.
  • Formwork should be as lightweight as possible without any strength reduction.
  • Forms should be made such that workers can handle them without any safety issue, respecting the Health, Safety, and Hygiene Regulation in effect.

CLEANING AND STORAGE OF FORMWORK:

  •  Formwork as soon as it is removed, cleaned with a stiff brush.
  • Dust, dirt, stubborn bits of concrete or grout removed.
  • Timber surface and uncoated ply coated with release agent before storing.
  • Steel form coated lightly with oil to prevent corrosion.
  • Damaged formwork sorted out and repaired before storage.
  • Depressions, nail holes repaired with suitable materials and lightly rubbed down to give smooth surface.
  • Panels and plywood sheets stored on a horizontally levelled floor.
  • Panels stored face to face to protect the surface.
  • Storage area protected from rain and moisture and well ventilated.
  • All formwork materials stacked off the ground.
  • Loose wailing, soldiers (struts) etc. stored with respective panels after numbering for proper match when reused.
  • Bolts, nuts, champs, pins, wedges, keys and ties stored in separate bins or boxes.
