Cem-FIL® alkali resistant (AR) glass fibers have been in use for 40 years in more than 100 countries worldwide to create some of the world's most stunning architecture while offering strong and durable performance in widely varying cement and mortar based applications, including floorings, renders, top screeds, tunnels, utility poles, etc.

Cem-FIL® AR glass fibers are unique as a concrete reinforcement. Cem-FIL® fibers have the same specific gravity as the aggregates, so assured fiber dispersion is easier to achieve than with other fibers. Cem-FIL® fiber contributes efficiently to the tensile strength before the concrete is able to crack thanks its high Elastic Modulus, its affinity and its efficient bonding with the concrete Cem-FIL® fibers offer superior performance to standard fiber reinforcing with widely varying addition rates designed to meet your specific project specifications.


  • Excellent compatibility with cement matrix
  • Excellent workability even at high dosage
  • Increases chemical resistance (e.g. deicing products)
  • Improves freeze/thaw resistance
  • Extends serviceability of concrete
  • Long term durability of concrete
  • Does not float or sink in concrete
  • Does not entrap air
  • Fast and uniform dispersion


Renders - Cem-FIL® AR glass fibers have been used successfully in Renders for over 30years by providing long term fiber performance to the render matrices. Reduction of plastic shrinkage cracking, reduced water migration, increased impact and abrasion resistance are achieved when Cem-FIL® is used at recommended addition rates.

Self Levelling Floor Screeds

Self levelling screeds can be used as a repair topping on worn or damaged slabs, or as an overlay to level uneven floor surfaces. Cem-FIL® fibers offer superior performance as a reinforcing fibre, and will not increase water demand or affect the set time of the mix. AR glass fibers have a similar specific gravity to that of the sand and stone used in concrete mixes.

Because of this attribute Cem-FIL® fibers will not adversely affect the finished surface of the floor.
