  Why EPDM track or Spray coat track do not bubble ? In the market, there are EPDM track, spray coat track,sandwich track, Full PU track, and prefabricated track . It sepereted by permeable and non-permeable track,EPDM track and Spray coat track belong to permeable track,sandwich track, full pu track and prefabricated track belong to non-permeable track. There are three reasons for rubber track bubbles : 1)The subbase problem; Regarding to Cement subbase, without waterproof layer When the cement foundation construct, or the cement was not maintained for 28 days after the completion of the cement, or the new cement foundation was maintained for 28 days but before the rubber track construction,it dont pickled （ by OXALIC ACID ） . These will cause blistering on the rubber tartan track.Regarding to AC (Asphalt) subbase, the asphalt was not compacted during construction. After the completion of the athletic track, the athletic track delamination and blistering, and the excavated rubbe...

  The synthetic running   track of the stadium has a large area, and the rainwater from the surrounding auditorium also flows into the venue. The venue must be used as soon as possible after the rain. The IAAF stipulates: "When the track and field ground is completely submerged, drain water for 20 minutes. Here The water depth of the ground area at any location shall not exceed the depth of the ground structure of the track and field". Site drainage can be a combination of surface runoff drainage and underground infiltration. If only ground runoff is used for drainage, the site is required to be flat and the flooding slope is very uniform, which is difficult for large-area football fields and field games. It is impossible to discharge by water seepage alone, because the water seepage capacity of the site is related to the site structure itself. Even if the water seepage is good, its water seepage capacity will become worse and worse as the service life increases. In addition...

Spray coat track is one kind of economic,easy installation,stable quality and environmentally friendly running rubber track.It is widely adopted by customers.It is generally used in China as high as 60% .How much do you know about spray coat track? T oday let’s make a detailed explanation for you. Spray coat track structure by PU binder as primer,rubber granules(SBR granules or EPDM granules)mixed with binder as the bottom layer,the top coat is by spray EPDM granules with PU materials.The standard thickness is 11-15mm ,normally the color is red, green or blue.Red color is more popular due to the UV resistant. Compared with others style rubber track (sandwich track,full PU track,perfabric track,EPDM track),spray coat track is the most economic rubber track,both suitable for indoor and outdoor ,concrete subbase and asphalt. It is very easy to install, the weather requirement is not too high ,after rain,only requested the surface dry ,then it can install again,no need to wait till the w...
