Many old basketball courts have been renovated into new ones, either through complete reconstruction or by making necessary repairs. Since each situation is unique, it's important to handle them individually. First, if you're removing the old court and building a new one, it's essential to fully demolish the existing site. The foundation should be properly compacted, and the construction should follow the new design specifications. It's not advisable to leave part of the old ground as a base and then build only half of the new court. This can lead to cracks in the new plastic surface layer. The old structure should be completely removed, and the base should be expanded to ensure a solid foundation before applying the new surface. Second, old asphalt and cement concrete courts with similar sizes should also be treated differently. For asphalt courts that have many cracks, it's important to clean the joints thoroughly and fill them with bitumen mastic. Larger damaged areas should be removed and replaced with new asphalt. After repairs, the surface should be cleaned, sprayed with a layer of tack oil, and finally covered with a fresh layer of asphalt. For old cement concrete courts, all expansion joints should be removed, cleaned, and filled with new materials. It's recommended to apply an asphalt layer on the existing surface, followed by a non-woven geotextile over the joints to prevent cracks from reflecting upward. Then, a new layer of asphalt concrete can be laid on top. Third, if the old cement brick or concrete structure is less than 10 cm thick, it's generally not advisable to use a paving method for the new plastic court. The original structure may be too weak, and once the new surface is installed, cracks are likely to appear. This issue has been commonly reported in previous renovations. Proper planning and careful execution are crucial when renovating an old basketball court. Whether it's asphalt, concrete, or brick, each material requires specific treatment to ensure long-lasting results and a safe playing surface for athletes. pocket door hardware,pocket door system,cabinet pocket door,soft close pocket door,retractable cabinet door Foshan Nanhai Ranming Lijiali Hardware Co., Ltd , https://www.lijialihardware.com
