    Podium Slab Waterproofing– Risks involved:


    An effective and durable waterproofing system is critical for ensuring the long-term durability of the structure and to keep maintenance costs to a necessary minimum. In sensitive building areas like podium slabs where you plan for water bodies, landscaping, children play area, sports facilities, car parking, driveways etc, proper waterproofing system helps to keep out water and pollutants, thereby, preventing leakages and also protecting the structural elements and embedded steel reinforcement from damage due to corrosion. A good waterproofing system has to ensure that it keeps performing at optimum level for a very long period of time, even beyond the warranty period, to provide maximum value and comfort to the end-user.

    Solution for Podium Slab Waterproofing

    Requirements:
    • Large open areas: for tensile & elongation properties to accommo- date thermal movements
    • Water bodies: as barriers to water ingress and continuous exposure to water
    • Sand filling: to enable sand filling directly on the membrane without protection screed
    • Chemical resistance to pesticides
    • Medium duty traffic: resistance to dynamic & impact load
    • Very high impact & puncture resistance: able to sustain mechanical abuse during construction
    • Zero VOC: environment-friendly, meets norms for green products for waterproofing
