1、 Physical defects
Grass shedding and lodging
Poor quality adhesive has insufficient bonding strength, and grass fibers are prone to fall off or collapse from the base fabric, resulting in uneven surfaces on the lawn.
Consequence: Decreased athletic performance (such as abnormal ball rolling trajectory and uneven friction), increasing the risk of athletes slipping or twisting.
Layering and cracking
The poor weather resistance of the backing adhesive (such as becoming brittle at low temperatures and softening at high temperatures) can lead to separation between the base fabric and the grass layer or cracking of the backing adhesive itself.
Impact: Damaging the overall structure of the lawn and accelerating the loss of filling materials (such as rubber particles being washed away by rainwater).
Decreased drainage performance
Poor quality adhesive can easily block the pores of the base fabric, hinder the normal operation of the drainage system, and cause water accumulation on the site.
Risk: Wet and slippery surfaces are prone to accidents, and long-term accumulation of water can breed bacteria or mold.

2、 Safety hazards
Toxic substance release
Poor quality adhesive may contain harmful components such as formaldehyde, benzene derivatives, heavy metals, etc., and release volatile organic compounds (VOCs) at high temperatures.
Health risks: Long term exposure may cause respiratory diseases, skin allergies, and even cancer (especially for children and athletes).
static electricity issue
Adhesive backing lacking anti-static treatment is prone to accumulating static electricity, adsorbing dust and particles, and may cause electrostatic shock discomfort in dry environments.

3、 Increased economic and maintenance costs
frequent repairs
The shedding or delamination of grass fibers requires continuous repair, and the labor and material costs far exceed the initial saved adhesive costs.
Case: The lifespan of high-quality adhesive backed lawns can reach 8-10 years, while inferior products may need to be replaced as a whole within 3-5 years.
Increased loss of filling material
The cracking of the backing adhesive leads to the loss of fillers (such as rubber particles), which requires frequent replenishment and increases maintenance costs.

4、 Environmental and Legal Risks
environmental pollution
The detached adhesive fragments and microplastics enter the soil or water, making it difficult to degrade and damaging the ecological environment.
Regulatory restrictions: EU regulations such as REACH and RoHS strictly limit the use of toxic chemicals, and poor quality adhesive backing may lead to site violations.
legal dispute
If personal injury is caused by the failure of the adhesive backing (such as athletes falling and breaking bones due to slippery surfaces), the responsible party may face consequences. High compensation or litigation
