Semi prefabricated runway is a modern runway material that combines the advantages of prefabricated and cast-in-place processes. The core structure is as follows: the elastic bottom layer is prefabricated in the factory, bonded with a special adhesive on site, the joints are sealed with cast-in-place polyurethane material, and finally the surface layer is sprayed to make the surface layer system a non permeable runway system.
The semi prefabricated runway combines the dual advantages of uniform thickness of prefabricated and seamless integration of cast-in-place, while also having good cost-effectiveness, making it a new choice for campus and social competition venues.

Semi prefabricated stadium is a new type of stadium material that uses factory prefabricated elastic rolls and on-site spray coating technology. The elastic layer is a factory prefabricated full plastic polyurethane elastic micro airbag roll (without doped particles or other materials), with stable chemical and physical properties and consistent thickness. After on-site installation, the reinforcement layer and topcoat layer are constructed to form a seamless integrated stadium surface layer system.
Semi prefabricated sports fields combine the quality stability of factory prefabrication with the flexibility and adaptability of on-site construction. They have uniform thickness, seamless processing, and long service life, making them a new trend in school and public sports field construction.
