Comparative Evaluation On The Absorption Rates Of Cementitious Coating And Integral Type Of Waterproofing

     This research evaluates a comparative study on the absorption rates of two methods of waterproofing which is integral waterproofing and cementitious coating. Waterproofing has become an essential component of a structure to protect its aesthetic appearance, prevent structural damages and for the safety of the occupants. In the construction industry, many commercially available materials are used for waterproofing roofs slab.

     Under this research, field surveys were carried out to identify the commercial brands of waterproofing material. Furthermore, questions regarding the choices of waterproofing materials were surveyed to identify what they would choose for a building to overcome the various environmental condition of degradation.

     Laboratory tests were performed on commercially available waterproofing to compare their absorption rates. The method of integral waterproofing and cementitious coating were used for this comparison. Three specimens were prepared using each waterproofing material. They were checked for absorption rates under time variations for about 24 hours.

     Finally, from the experiment, it is concluded that cementitious waterproofing systems perform better than the integral waterproofing. Among the used commercial waterproofing materials, Concretobond waterproof coating showed better performance than the other materials.
