How to deal with bulges and wrinkles in football fields?

When we are paving artificial turf, we often encounter various problems. GZUNIGRASS provides solutions to several core problems, which are also relatively common problems. Bulge is a common problem encountered by customers. There are many reasons for bulge, mainly the following four: improper transportation, unbalanced lifting, poor winding process, and improper construction method.

It is also worth noting that if the temperature of the artificial turf field is too low and the turf is stored for too long after production, it will also cause a certain degree of deformation (bulging)

So how to solve the bulging problem? We can solve it in three steps:

1. When the ambient temperature is above 25°C, open the grass roll and dry it. After the grass blanket becomes soft, use uniform force to flatten the bulge in the unfolding direction (repeat the operation many times until the bulge disappears

2. When the temperature is below zero, deal with slight bulges, roll up the opened lawn, roll it in the rolling direction, roll about 50m, open it again for verification, if it is not completely eliminated, roll it up many times, roll it open until the bulge is completely eliminated; if it is still not eliminated, use a small amount of 80°C hot water, cover it with a quilt, and step on it repeatedly until the bulge disappears;

3. For the small bulges at the beginning and end of the artificial turf, the edge of the wood ear, apply glue to fix it, and squeeze out the bulging part. Wrinkles are two common problems of lawns. Similar to bulges, wrinkles will also change the flatness of the blanket surface and affect normal Construction and use.

The main factors are: reversal and scraping during transportation and loading and unloading, displacement caused by incomplete glue curing at the joints, and the wood ear edge is mainly caused by the force on the edge of the bottom fabric after nailing and rolling, and a regular wood ear edge is formed after storage for a period of time.

The same treatment method as the bulge, three steps are used to solve it:
1. Place the lawn neatly in place according to the pre-designed paving direction, and unfold the lawn in turn. It should be noted that the inclination and inversion of the lawn grass must be consistent. The lawn must be placed for 24 hours after it is unfolded on the site to ensure that the stress of the lawn is completely released.

2. After the lawn is unfolded, move the lawn with uniform force along the unfolding direction to ensure that the lawn will not be folded or slightly bulged due to the gradual relaxation of tension during the opening process. It is forbidden to roll the lawn halfway and leave halfway during the opening process to avoid other quality problems.

3. It is forbidden to throw, drop, fall, etc. directly, and rolling in the opposite direction is forbidden. The stacking site is flat, and heavy pressure, emptying, and tilting are prohibited.
