If the foundation does not meet the standards, it will have various adverse effects on the use of silicon PU stadium materials, as follows:

In terms of structural stability

Cracks appear: If there are problems such as insufficient strength and compaction of the foundation ground, after the laying of the silicon PU stadium material, cracks may occur in the foundation due to external forces such as personnel activities and sports equipment during use, which may lead to cracks in the silicon PU surface layer, affecting the appearance and performance of the stadium, and even causing local collapse in severe cases.

Delamination and hollowing: Poor surface flatness, floating dust or debris on the foundation can cause insufficient adhesion between the silicon PU material and the foundation, resulting in delamination and hollowing. This not only makes the stadium prone to abnormal noise during use, but also accelerates the damage of the silicon PU material, reducing the service life of the stadium.

In terms of drainage performance

Water accumulation problem: The drainage slope of the foundation ground does not meet the requirements, which can cause water accumulation in the stadium after rain or cleaning. Water accumulation can keep silicon PU materials in a damp state for a long time, accelerating their aging and degradation, affecting their elasticity and wear resistance. Moreover, athletes who exercise on waterlogged courts are prone to slipping and getting injured, which affects their sports experience and safety.

In terms of thermal expansion and contraction

Expansion joint problem: The foundation is not equipped with expansion joints according to regulations or the expansion joints are not set reasonably. When the temperature changes, the degree of thermal expansion and contraction between the silicon PU stadium material and the foundation will be different, resulting in internal stress. If the internal stress cannot be effectively released, it will lead to problems such as bulging and cracking of the silicon PU surface layer, especially in areas with large temperature differences, where this phenomenon will be more pronounced.

Overall performance aspect

Uneven elasticity: Uneven flatness and compactness of the foundation can result in uneven thickness of the silicon PU stadium material after laying, leading to uneven elasticity of the stadium. This can affect athletes' athletic performance, such as uneven force distribution during running and jumping, increasing the risk of injury for athletes.

Shortened service life: The various problems caused by substandard foundations mentioned above will directly or indirectly accelerate the damage of silicon PU stadium materials, making it impossible for the stadium to reach its normal service life and increasing the cost of later maintenance and replacement.
