Zemdrain® controlled permeability formwork liner

The primary cause of concrete degradation is the poor quality of the outer 20mm of the surface due to the use of oiled impermeable formwork. The resulting surface has increased porosity and numerous blowholes and reduced durability.


Zemdrain® CPF formwork liners are attached to the formwork face and during the concreting process remove excess air and water from the formwork/concrete interface. The resulting high quality concrete surface has significantly increased durability properties.


Concrete formed with Zemdrain® has the following benefits:

  • Virtually blowhole and blemish free surfaces
  • Surfaces uncontaminated by release agent residues
  • Surfaces with a lower w/c ratio
  • Increased surface hardness and density
  • Increased chloride and carbonation resistance
  • Improved freeze/thaw resistance
  • Improved abrasion resistance

Zemdrain® can be used for all concrete structures. However, the principal uses are for infrastructure projects such as drinking water reservoirs, water treatment plants, wastewater treatment plants, sewage treatment plants, locks, bridges and marine structures. Quality exposed concrete surfaces can also be produced using a Zemdrain® liner.


There are different types of Zemdrain® – Zemdrain® Classic, Zemdrain® MD and Zemdrain® MD self-adhesive. All liners give the same levels of improvement in concrete performance, however, their use and fixing to different formwork systems is different.
