  • Effective in all types of moulds and formwork
  • Penetrates timber to help make it more water resistant
  • Useable on plastic and rubber
  • Is VOC compliant, non-toxic and environmentally safe

Concrete Remover

This is a biodegradable solution designed to soften and easily remove concrete or cement residues from tools or concrete placing equipment. It eliminates the need for hammering, sand blasting or chipping to remove old concrete residues.

Self-Adhesive Expansion Foam

Easy Form is an expansion joint filler for expansion/isolation joints in poured in situ concrete related construction. It is self-adhesive and has a ZIP TOP that can be torn off for when a sealant is to be used.

  • Anywhere an element needs to be permanently separated or provision made for expansion and contraction in concrete slabs: Pavements, driveways, floor slabs etc
  • Where driveways or pavements meet: building claddings, retaining walls, pre-poured columns, or plant bases
  • Between swimming pools and concrete paving
  • Solution to weed control between joints
  • Easy to use; Light, flexible and easily cut on site with a sharp knife

NB. When the application does not require a sealant, Easy-Form should be installed upside down, with the zipped top down to avoid unwanted removal.
