When Subaru had the intention to build a new extension adjacent to the existing building, the design was to link the roofs of the two building eventually together as one single roof. Sumitomo Mitsui being the Main Contractor needed to make a right decision on the choice of waterproofing system to the roof. Recognizing that the roof is going to cover both showroom and workshop in the future, any leakage would not be desirable. Even if somehow unlikely leakage is identified, the defect must be dealt with quickly and arrested effectively. With this thinking, Sumitomo Mitsui relied on Cementaid Caltite system to do the work. Indeed, it is performing well and subsequently several similar showrooms and workshops in the pipeline were under Cementaid’s care as well. Indeed, they are happy customers of Cementaid!
