Fibrillated micro synthetic fibres

Fibrillated Fibres: Crackstop F

Crackstop F is is a fibrillated microfibre that reduces the occurrence of plastic shrinkage cracking and plastic settlement whilst enhancing the surface properties and the durability of hardened cementitious products.

Fibrin 660F

Fibrillated fibres have been developed and manufactured to provide optimum performance for each individual construction need. The fibres are cut into different lengths with various thicknesses. Special coatings are added to the fibre within the production process to optimize dispersion and bond within the concrete. As do all Adfil fibres, our range of fibrillated fibres delivers a number of benefits over steel reinforcement. Examples include economic savings, environmental sustainability, logistical benefits, as well as improved health and safety conditions on-site.
