In 2022, Hangzhou Asian Games E-sports hall was located in beijingyuan ecological park in Xiacheng District. It is the first venue in China to meet the official competition standard of Asian Games E-sports. It has the characteristics of "digitization", "intelligence" and "specialization", and is committed to building an international first-class E-sports professional competition venue.

The overall design concept of the venue is "interstellar vortex", with a total construction area of about 80000 square meters and 4087 seats, of which the area designed with polyurea as waterproof is 15000 square meters. Polyurea material of Qingdao Advanced Marine Material Technology CO.,LTD has become the only designated polyurea material for roof waterproof of E-sports hall.

Polyurea spraying technology is a solvent-free and pollution-free on-site spraying technology developed to meet the needs of environmental protection. Its main advantages are:

v Green environmental protection, polar VOC's, environmentally friendly;

v Fast curing, 10s gel, 10min reached walking intensity.

v The prototype has good reproducibility and no sagging of complex surfaces;

v The construction thickness is formed at one time to overcome the disadvantages caused by multi-layer construction;

v Excellent physical properties, high tensile strength, high elongation, good medium resistance, good wear resistance, excellent impact resistance, etc;

v Large adjustable range of hardness (Shao A50 -- Shao D70);

v The coating is seamless and dense, with excellent waterproof and anti-corrosion effects;

v Good adhesion to concrete, iron / steel / stainless steel, aluminum, copper, rubber, wood and other substrates;

v The construction speed is fast, and the daily construction of a single machine is more than 1000 ㎡;

v Low comprehensive cost, no additional maintenance, one-time investment and lifelong benefit.
