Sika® Fibermesh® concrete fiber blends are a combination of microsynthetic fibers and either macrosynthetic fibers or steel fibers. The resulting Novomesh® family of products represents the best possible solution to concrete’s intrinsic flaws throughout its life span. Micro fibers excel at controlling cracks in the early stage, while Macro (synthetic or steel) fibers provide outstanding crack control in increased load-bearing situations. With blended fibers, you receive both advantages in one amazing package.
