Concrete fiber dosage
How a Polyguard dose is designed, mixed and placed — and what to expect on site.
The process
Send us the element thickness, subgrade, exposure class and loading. We calculate the residual strength the design needs and return a dosage in kg/m³ with the matching fiber grade.
Fibers are added at the batching plant or in the truck and mixed at full speed for the specified time. We attend the trial, check dispersion and adjust workability with the mix designer.
Placing, screeding and power floating follow normal practice. No mesh to lift, no chairs to walk on, and no cover to protect — the crew gets a clear slab and a faster cycle.
Fields of use
Racking legs and forklift wheels put point loads on a slab all day. Macro fiber distributes reinforcement through the full depth, so the slab keeps working after the first crack instead of relying on a single mesh layer sitting at one level.
Fixing mesh overhead in a tunnel is slow, and it is the part of the cycle where people get hurt. Fiber goes in at the mixer, so the lining is reinforced the moment it leaves the nozzle.
Thin panels crack during demoulding, stacking and lifting long before they are ever loaded in service. Fiber carries those handling stresses, and because it cannot corrode there is no rust bleed on the visible face.
On bus lanes, ports and industrial yards the failure mode is rutting and reflective cracking, not a lack of strength. Fiber holds the binder film in place and spreads the stress through the layer.
