ASC — Installation Of AGV Floor

Lidcombe , NSW

Reason For Repair

  • The floor was uneven and unsuitable in its current condition for AGV’s use.
  • Slabs on either side of the expansion joints had moved and were at different heights.
  • Expansion joints were cracked and open due to years of wear and tear.

Step 1 : Preparation Of The Floor

  • The floor needed to be ground to clean the concrete and open up capillaries for a stronger bond to the existing floor.
  • 3 phase remote control diamond grinders were used to prepare the floor.
  • Expansion joints are saw-cut and repaired using an epoxy compound to create a stronger joint.
  • All inconsistencies are filled with an epoxy mortar to ensure a level surface.
  • The floor was then vacuumed to ensure no dust or dirt remained on the surface.
  • The surface is now clean and contaminant free ready for coating installation.

Step 2 : Installation

  • The floor was divided into 4 sections along expansion joints.
  • Expansion joints and edges were protected with foam tape.
  • The floor was installed in a staggered manner to guarantee a wet edge and level continuity.
  • Sections 1 and 3 were completed first followed by sections 2 and 4 the day after. This was essential in order to allow the product to cure fully before the next sections could be completed.
