What are ACTIV slabs?

wat zijn vloerplaten

ACTIV Slabs are used as the constructive and aesthetic underside of concrete floors in applications in buildings with concrete floor core activation (BKA). With concrete core activation (BKA) floors are thermally activated by circulating cold or warm water through pipes that are laid in the floor components.
ACTIV Slabs feature under-reinforcement into which the pipe network for the BKA is inserted.
The upper reinforcement is applied after installing the ACTIV Slabs. Finally, concrete is poured onto the plates up to the desired floor thickness. The result is a solid concrete floor where the load is perfectly distributed, where the thermal inertia activation is used to regulate the climate.
The Kerkstoel ACTIV Slabs are made of reinforced concrete which complies with:

  • the PTV 202 Probeton BENOR regulations for Belgium,
  • the KOMO regulations, regulations for the Netherlands
  • the certificate with product certificate number K2188/95 and the ISO 9001 standards.
