With our basalt fibres you are technologically up to date. Compared to conventional staple fibres made from alkali resistant glass, laboratory tests prove up to 20% higher flexural strength of the concrete. Basalt fibres are also more heat resistant than glass fibres and thus the ideal reinforcement for refractory concrete, such as our GRISU®.
Rely on our basalt fibres for both refractory and normal concrete. The fibers are protected by a special waterproofing and thereby not sensitive to any alkalinity of the concrete.
For effective static reinforcement, the fibre content must be at least 2% of the mortar weight. In situations where it's all about reducing the risk of shrinkage cracks, a significantly lower dosage is sufficient.
In our online shop you buy glass fibres only from renowned manufacturers, in small quantities at a reasonable price.
