tennis courts the construction of tennis courts begins with the construction of the base this is a very important step since the quality of the base determines the service life of the product the workers dig the trench the depth of which usually doesn't exceed 60 centimeters a layer of slaked lime or other fungicide is then applied it's a chemical that prevents vegetation from germinating the next layer is a waterproof material and they send a cushion about ten centimeters thick then concrete or clay diet concrete is poured over the sand the surface is preliminary reinforced in order for the tennis court to be of high quality the concrete is poured without interruption in one cycle this eliminates the presence of surface joints before the surface finishes drawing it is leveled the use of laser leveling technology considerably accelerates the process special equipment uses lasers and sensors that allow the operators to produce a perfectly flat surface it should be noted that the surface must have a slight inclination this will prevent rainwater from accumulating in puddles after the drying process which lasts approximately a month the surface is polished a layer of between two and four millimeters of primer is applied the last stage of the construction is the placement of the artificial surface it can be grass or as in this case a special material to create a hard tennis court it's a water acrylic solution it's usually applied in several layers from three to twelve and each layer can have its own special function for example the alignment of the base the softening of the surface and the coloration of the school turf is the most popular cover of modern football fields its advantages include that it's easy to maintain and has a perfectly flat surface in addition it doesn't suffer from being warped on and doesn't need to be watered high-quality artificial turf like the one shown in the video does Shyne either on the outside it's almost indistinguishable from real grass the wool material for the artificial grass is polypropylene or polyethylene the fibers are manufactured through the extrusion process in their original form they are enormous rolls of plastic special machines make bundles of fiber and then weave them together to create a wide band for the coating to be strong and durable a latex base is applied to the inside of the covering after the artificial turf is drive and tested for quality it's rolled up it is then taken to these stadiums in areas where the fields will be installed in this case the football field the weight of one of these rolls can reach one ton so especially equipped loaders are used for spreading it then the layers must be spread and leveled manually of course the joints must be connected to each other a special adhesive is used for this and pressure is applied the markings are made of exactly the same grass but from white fiber to do this the groups are cousins of the finish coating they're then filled with glue and marking strips the final step is the application of filler materials such as sand and rubber granules and the final grooming these procedures increase the stability wear resistance and stiffness of the field baskyball course there are several materials available for making basketball course however parquet is the benchmark the highest quality material it's eco-friendly and prestigious proper production and installation will give the basketball court between 60 and 70 years of operation the material is taken to the stadiums in the form of separate sheets it's not an easy task to put them together either since wood is a rather fragile material there is a risk of damaging the parquet when it's laid carelessly tools such as a sledge hammer a pounding block a drift pen and a hammer are used for installation each panel has slots on all four sides all of these tools are needed to insert one slots into the other and then combine them to make the panel's fit as tightly as possible the wood is rigid enough only construction must be strong this is why parquet is laid on an elastic subfloor or on a system of bars and rubber gaskets sometimes to smooth the surface once the installation is finished it is polished next there's a mandatory stage designed to increase the durability and aesthetics of the basketball cause this is a wood coating with special varnishes and oils in several layers after the lacquer is dried if necessary drawings and markings are applied to the floor ice-skating rink ice hockey and figure skating rinks are not always created in specially designed places sometimes as in this case you have to work in ordinary and large stadiums the first stage before construction even begins consists of placing an enormous sheets of plastic this is necessary for installation the next layer is the plastic tubes which are taken to the construction site in the former role in this particular case 53 kilometers of pipes were used for construction they are filled with antifreeze this is a special liquid which can be cooled considerably without turning into ice a powerful liquid cooling device reduces the antifreeze temperature below zero degrees Celsius in five seconds then the field becomes a huge generator of cold a similar technology by the way is used in domestic refrigerators the next step is to start creating ice which requires filling the entire site with water in this case 50,000 litres were needed it should be noted that the builders don't immediately pour all this water into the building site to prevent air bubbles from forming in the ice the water must be placed in thin layers and then you have to wait until it freezes the prepared ice rink usually consists of at least 30 of these ice layers in the last layers of the water white paint is out it's a cover the pink chips with antifreeze the markings are applied during the creation of the ice rink two more centimetres of ice are placed on top of this layer volleyball court there are a number of varieties of volleyball for example it's played on sand and snow classic volleyball is one in which participants compete on specially constructed course the video shows a time-lapse construction of the volleyball course as well as these stands special crumb rubber mats are placed on a concrete or wooden base they are then spackled a polyurethane filling layer is then applied the only thing left to do is to varnish the surface very often wood plastic and special mixtures are also used as the final coating we'd also like to talk about building beach volleyball courts as you may have guessed special sand is used it's carefully saved and there's not a single stone or shell in all of this mass the proper filling for a volleyball court consists of 96% courts at the same time the size of the grain of the sand doesn't exceed two millimeters elastic bands are generally used to create the boundaries of the course this isn't soft and elastic material that doesn't have the players it shall be noted that the posts of the nets are installed before the sites is filled with sand in order to guarantee stability hey stop being lazy
