The polyurethane surface is a mixture of resin and rubber granules, poured onto a previously prepared foundation. Polyurethane surfaces work well wherever very high performance parameters are necessary, while maintaining high strength. For this reason these are the surfaces most commonly used in sports facilities, and for some time there has been growing interest in polyurethane surfaces when implementing non-sport investments.
Polyurethane surfaces - advantages:
- polyurethane sports surfaces are a type of jointless surfaces with a uniform structure, because of which they are very durable and very resistant to mechanical damage,
- polyurethane surfaces require minimal maintenance work, so even very intensive use is cheap,
- sports polyurethane surfaces are elastic and flexible, athletes are provided with comfort and safety during training and competition, both at amateur and professional levels,
- polyurethane sports surfaces are available in a wide range of colors, thanks to which they can be freely integrated into their surroundings.
Polyurethane sport surfaces - types and purpose:
Depending on the type of substrate and the type of granulate used, polyurethane surfaces are divided into:
- Water-impermeable polyurethane surfaces - most often covering asphalt, concrete or mixed asphalt-concrete substrates; In addition to the purely technical advantages, such as the possibility of designing optimal parameters, they also have a purely economic value - they allow the adaptation of existing concrete or asphalt surfaces to modern and safe sports surfaces.
- Water-permeable polyurethane surfaces – generally made over a mineral foundation, they are characterized by a high strength and resistance to wear; due to their water permeability, they are ecological, as they do not stop the natural penetration of rainwater and slush water into the soil.
Polyurethane surfaces - where to use:
Until recently, polyurethane surfaces were used mainly in sports facilities, both those intended for professionals and players, as well as those for amateurs. For some time the excellent properties of polyurethane surfaces have also been appreciated by investors who also design non-sport spaces for vehicle or transport activity.
Where polyurethane sport surfaces are most commonly used:
- Athletics tracks (running, long jump, javelin). Athletic tracks demand polyurethane surfaces capable of intensive use by specialist sports shoes with spikes, which is why they must be characterized by extreme mechanical strength. Both water permeable and impermeable athletics tracks are constructed using a suitable foundation.
- Multifunctional fields of polyurethane surfaces; built mainly in schools, housing estates and other public facilities as versatile fields for team games such as basketball, volleyball and handball. Multi-functional pitches of polyurethane surfaces are generally designed and installed as water permeable over a mineral substrate.
- Internal polyurethane surfaces installed in sports halls, gyms, and fitness halls.
- Tennis courts with a polyurethane surface, due to their high cushioning and elasticity, are very safe for joints. The specificity of the surface makes it impossible to slip, as on clay courts, and using the right type and thickness of underlay can produce a high ball speed and good bounce dynamics.
