Plastic playground surfaces

Special surfaces. These are surfaces made of various flexible plastics, used as carpets with a thickness from a few to several millimeters, laid on hardened substrates. These rugs can be single-layer or multi-layer, permeable to water or full. They can be poured onto the ground or a pre-fabricated carpet can be laid out. The substrate is concrete or asphalt concrete, which can be porous - water permeable. Surfaces of this type were used for the first time in 1961 year in the USA. In Poland, the first surface of this type on the running track of the stadium was made by Skra in 1969 of the year, the American company Minesota Tartan. Since then, these surfaces are called tartan surfaces, although the name of this product and technology are proprietary. In Poland, attempts were made to produce a similar material based on polyurethane and granulated rubber. Attempts were successful and since 1972 do 1977 years were made in Poland over 50 thousand, m2 of surface on various pitches. This material was named Torpol.
Plastic surfaces, thanks to many advantages, have become very attractive and are increasingly used all over the world. The most important advantage is resilience, flexibility, excellent adhesion and high mechanical strength. Low thermal conductivity and the ability to suppress noise made, that they are called warm and quiet. These materials can be given a different color. These features ensure safety in running various games, almost complete independence from outdoor weather influences and very low maintenance costs.
One of the disadvantages of plastic surfaces, especially in open terrain, is aging under the influence of solar radiation, consisting in the loss of flexibility and elasticity. Their durability in these conditions is 5-8 years. The cost of execution is greater than the cost of hard surfaces, e.g.. asphalt concrete.
