Level 1 fibres are designed to reduce plastic shrinkage cracking in concrete in the first 24 hours after placing and finishing. Very fine monofilament fibres are used at a typical dosage of 0.6kg per cubic metre of concrete to reduce plastic shrinkage cracking prior to initial set. They are easy to add and mix and result in a near-invisible surface finish.
Recommended for concrete applications such as slabs-on-ground, overlays/toppings, curbs, driveways, foot paths, basement floors, garage floors, and coloured concrete – anywhere that the objective is to control plastic shrinkage cracking while improving basic durability properties. Requires no mix design or placement changes. Product Reference: FORTA Mighty-Mono® |
Level 2 fibres are designed to reduce plastic and hardening shrinkage cracking in concrete and to act as an alternative reinforcing system to wire mesh in non-structural applications. Fibrillated, or net-shaped fibres are used at a typical dosage of 0.9kg per cubic metre of concrete to reduce plastic and hardening shrinkage. Recommended for use in quality concrete applications such as slabs-on ground, overlays/toppings, curbs, sloped paving, roads, driveways, footpaths, shotcrete, tilt-up panels, architectural/coloured concrete, precast, water tanks, and sewage treatment facilities – anywhere that peak fibre performance is desired and where the objective is to control temperature/shrinkage cracking while improving basic durability properties. Requires no mix design or placement changes.

Level 3 fibres represent the next generation of synthetic fibre technology and are capable of a much higher replacement level of conventional steel reinforcement. The FORTA FERRO® macro fibre system maximises each of the critical fibre characteristics that contribute to long-term durability and crack-control performance. Using advanced co-polymer chemistry, a blend of fibre shapes along with twisted bundles and special grey colour to assure uniform mixing and an excellent surface finish, this unique best-of-its-kind macrosynthetic fibre system may be used at much higher dosages (3.5kg, 4.5kg per cubic metre or more) without losing its user friendly reputation. FORTA FERRO® provides the highest slab curling reduction and post-crack performance values of any synthetic fibre in its class.
