artificial lawn foundation treatment

The plastic basketball scene adhesive silicon PU

Better than the basketball court are flexible plastic stadium colorful, this rubber surface of silicon pu silicon the pu vibration absorption: When Silicon PU withstand an instant impact, 63% of the impact is absorbed by the ground system, better protect the athlete's ankle.

Silicon PU stadium material, a sport utility and construction advantages the national patent stadium materials.
Modified silicone elastomer particles and other technologies to achieve the PU material may directly on the concrete floor construction.
And does not appear to cracking and bubbling.
Also has excellent characteristics of conventional PU and acrylic.
The underlying silicon PU is a polymer material, xylene diluent. Is the the sports stadium works best choice!

Silicon PU basketball court construction

Asphalt foundation: the surface uniformly solid, no oil, no not stirred open asphalt block, smooth and no cracks, no bad side heap crowded, no Ma surface is smooth, smooth seams, no water blocking phenomenon, compaction density of not less than 95% , after the pressure of the medium-sized rolling machine, without significant wheel tracking no feeble peeling, no loose topsoil, wave phenomena, flatness 3mm ruler error is less than 3mm, the flatness of the pass rate is more than 90%, there is a certain drainage slope to ensure sluicing. New asphalt base Nature Conservancy of not less than 28 days, the high boiling volatiles volatile asphalt completely to ensure good bond Silicon PU material base.

artificial lawn foundation treatment: cleaning with detergent water or detergent water solution to clean the base surface, then rinse with water after cleaning should be based on the dirty objects and other floating loose debris. The cleaning standard good the hydrocephalus bit identification mark. Leveling: professional underlying TB-202 by the group A: B group = 1:2.5 (weight ratio) ratio stir (can be adjustable water adding construction consistency) Scratch on the base surface with plastic blade divided into two or more, and requires the the base surface voids filled, sealed, no pinholes, surface smoothness dryness. Behind the construction does not affect the base surface voids the first Scratch A set of copies of the same weight can be added fine sand (40 to 80 mesh), Stir Scratch. Hydrocephalus leveling patch: the processing requirements under the new cement foundation.
