Abstract

Sheet based waterproofing methods are factory produced and have a advantage or forming uniform waterproofing layer in construction sites, allowing them to become a commonly used material domestically. Particularly in the case of EVA waterproofing sheets, they can be manufacturing using recycled materials and are thus increasing in application due to their eco-friendly factors. However, heating adhesion method has to be used in case of overlapping areas of waterproofing sheets, but not enough studies have been made on the adhesion stability based on different heat adhesion speed. In this paper, EVA sheets have been studied with their overlap area properties following a heat adhesion method in wintertime ambient conditions and have been observed for the changes in the tensile strength based on different head adhesion speed and rates. According to the results, 6~7m/min adhesion speed was shown to have produce the best tensile strength.
