Dimensions Of The Pitch, Including Runs. Is 32.1 X 20.1 M. The Playing Fields Are Limited By A 10 Cm Thick Line. Designed For Playing Volleyball And Tennis, In Accordance With Applicable Sports Norms And Standards. The Polyurethane Surface Should Be Adapted To Intensive Use, Resistant To Weather Conditions, With High Anti-Slip Properties And Must Have Certificates. Scope Of Work: - Polyurethane Surface 625 M2 Sports Surface, Polyurethane And Rubber, With A Layer Thickness Of At Least 13 Mm, Permeable To Water, With Compact Structure. The Surface Must Have The Wa Certificate, The Hygienic Certificate Of The National Institute Of Hygiene And Meet The Requirements Of The Pn-En 14877:2014 Standard. The Surface Consists Of Two Flexible (Load-Bearing) And Functional Layers. The Supporting Layer Is A Mixture Of Rubber Granulate And Polyurethane Binder. It Is Laid Mechanically, Seamlessly, Using A Polyurethane Mass Spreader. The Layer Made In This Way Should Be Covered With A Wear Layer, Which Is A Polyurethane System Mixed With Epdm Granules. This Operation Is Performed By Mechanical Spraying (Using A Special Sprayer). The Thickness Of The Wear Layer Is 2-3Mm. After The Mixture Has Completely Set, The Lines Are Painted With Polyurethane Paints By Spraying. Polyurethane Surface With Structural Spraying, Flexible, Jointless, Water-Permeable, Spike-Resistant, Machine-Installed In Situ (Directly On The Construction Site). The Total Thickness Of The Surface Is At Least 13 Mm. The Height Of The Posts And Other Technical Parameters Must Be In Accordance With The Regulations Of The Relevant Sports Federations. - Subscription Polyurethane Substructure, Flexible, Jointless, Water-Permeable, Machine-Installed In Situ (Directly On The Construction Site). Et Sub-Base Can Replace Concrete Or Asphalt Concrete Sub-Bases. Raw Materials Necessary To Make The Foundation Layer: - One-Component Polyurethane Binder [15.0 Kg/M2] - Sbr Granules 1-4 Mm [14.0 Kg/M2] - Mineral Aggregate 2-5 Mm [2.7 Kg/M2] - Lay The Foundation On A Mineral Layer Substrate. Construction Of The Substructure: Preparation Of The Subfloor - The Subfloor Should Be Thoroughly Tamped Or Vibrated With Special Devices And Prepared In Accordance With The Design. The Substrate Temperature Must Be At Least 3°C ​​Above The Current Dew Point Temperature. Preparation Of The Foundation Layer - In A Special Mixer, Thoroughly Mix Sbr Rubber Granules With Mineral Aggregate And Polyurethane Binder So As To Cover The Entire Batch With Glue. Place The Prepared Mixture On The Prepared Substrate Using A Spreader. Leave The Stabilizing Layer To Hard
