Freeplan-I slab on insulation

In cold storage facilities, deterioration at saw cut joints become even more critical as it is a real challenge to repair them at low temperature.

That is why the 'joint-free' FREEPLAN system is perfectly suitable to the application in refrigerated warehouses on insulation.

The absence of rebar allows for a smooth and safe slab installation process, directly on the insulation boards, with the use of Laser Screed and Topping Spreader fitted with airplane tires and extended baseplates.

The Twintec armored joints are installed with special feet so the insulation boards will not be perforated or damaged. These joints will offer optimal load transfer and steel arris protection while allowing a free slab movement in both horizontal directions.


  • Design is improved by the continuity of the floor. Edge and corner loads are not critical as the only joints in the slab are armored joint designed to transfer the maximum load.
  • The absence of joints will enhance the flexibility in terms of building use and racking layout. Metallic construction joints can be located strategically under racking or in areas with less traffic.
  • The performance of steel fiber reinforced concrete (SFRC) increases the durability of the finished floor in terms of structural performance, but also fatigue, abrasion and impact resistance. 
  • Safer and faster installation: with steel fibers reinforcement, there is no need for rebar to be placed prior to the concrete works and continuous large panel pouring can be achieved - by the use of a pump or Telebelt and with the use of the Laser Screed - providing a safer working environment.
  • Improved long term flatness tolerances by suppressing the curling effect of saw cut joints.
  • Reduced maintenance costs and improved material handling equipment (MHE) efficiency: by eliminating saw-cut joints, the FREEPLAN system eliminates the biggest cause of problems and of ongoing maintenance of both floor and equipment. A 'joint-free' floor will also optimize the MHE efficiency and performance.
