Astra PolyEx Mesh concrete fiber - Skateparks and Sports Playgrounds Solution
The construction of modern skate parks , sports fields , bike paths and recreational areas requires not only thoughtful design, but also the use of high-quality building materials. One of such materials is the copolymer fiber for concrete Astra Polyex Mesh , which has become an effective alternative to steel reinforcement.
What is Astra Polyex Mesh fiber ?
Astra Polyex Mesh is a copolymer fiber in lengths of 24, 38, 54 mm , which is added to the concrete mix for its micro-reinforcement. Due to its unique structure (monofilament or fibrils), the fiber is evenly distributed in the body of the concrete, improving its mechanical characteristics without the use of steel reinforcement or meshes.
The main advantages of fiber for sports construction:
✅ Increased tensile, compressive and bending strength
✅ High impact resistance - important for high-use areas such as skatepark ramps
✅ Resistant to cracking and abrasion
✅ Reducing the risk of shrinkage cracks
✅ Optimal resistance to frost, moisture, UV radiation and chemical reagents
Fiber also improves the ease of placing the concrete mix, does not rust or cause corrosion, which is extremely important for outdoor use.
Where is Astra Polyex Mesh fiber used?
Skateparks, sports fields, running tracks, bike parks 
Industrial concrete floors
Bridge and road surfaces
Outdoor areas, parking lots
Foundations, floor slabs, concrete columns
Building mortars, cement-sand screeds, plasters
Small architectural forms
Types of Astra Polyex Mesh fiber:
-
Shape: monofilament/fibrils
-
Material: polypropylene / copolymer
-
Diameter: 0.069 mm
-
Linear density: 3020 dtex
-
Tensile strength: 620–758 MPa

Dosage and savings:
The recommended dosage of fiber is 1–3 kg per 1 m³ of concrete . In cases of increased strength requirements, the dosage can be increased to 0.5% of the concrete volume .
Unlike steel fiber, which requires 20–40 kg per cubic meter, Astra Polyex Mesh is much more economical and easier to use , without weighing down the mixture or damaging the laying equipment.
