Abstract

One of the factors that make the infrastructure last longer is the waterproofing materials used.Weather factors that occur in Malaysia are the main cause in selection of a waterproof material to maintain the lifespan of a building or residential structure. Waterproofing is vital in humid tropical climatic regions such as Malaysia, and waterproofing chosen as the material will be determined by the extent of material exposure to rainwater. Furthermore, Universiti Teknikal Malaysia Melaka technology campus has encountered a few problems concerning bad waterproofing. Therefore, a comparative study on the effectiveness of cementitious and elastomeric waterproofing materials is conducted to help UTeM maintenance team on cost-effective strategy. Standard testing using ASTM D5957: Flood Testing Horizontal Waterproofing Installations will be the benchmark for this assessment to give an accurate testing analysis. Existing material data from an open literature study was used to determine the method, areas of application, and standards to analysis waterproofing. Testing of the specimen follow as per requirement of ASTM standard. Three tests will be performed on the specimens which are Water Penetration, Hardness Test and Water Absorption. The study findings show that the water penetration test resembles the ASTM D5957 standard. Other than that, Water Absorption ASTM D570 is applied to measure the quantity of water absorbed under specific conditions. Due to its high porosity, Cementitious waterproofing gained more weight compared to Elastomeric waterproofing. Based on the observations and analysis result, Elastomeric waterproofing material proves to be more effective compared to Cementitious waterproofing although both waterproofing materials comply with ASTM D5957 standards. It gives assurance that the ASTM D5957 standard used in this study may be used to testing the integrity of waterproofing material successfully.
