The problems encountered during the construction of the rubber track and the treatment measures rubber bulging, delamination from the foundation After the rubber track is finished, local or large-area bulging occurs in a short period of time, or it is separated from the foundation. Cause Analysis: If the cement label is unqualified or the basic water and gas barrier is unqualified, the ground water vapor rises and lifts the plastic layer, causing the plastic layer to bulge. Treatment measures: Cut off the bubbling part, dry the foundation and do a waterproofing treatment, then fill it up as required, and then fill in the color difference. Precaution: Strictly control the quality of basic waterproofing. When laying PU plastic, the basic moisture content and air humidity should be within a safe range.
