Maruti Rubber Group of Industries proudly engineered and supplied high-performance PVC Water Stop Seals for the landmark NCRTC Project (Ghaziabad Metro Station) in Ghaziabad, Uttar Pradesh. Manufactured under strict ISI Mark IS:15058/2002 compliance, these specialized ribbed seals with a central bulb (size 230mm x 6mm) were deployed by Vaibhav Construction. The project underscores Maruti's role as a trusted partner in nationwide transit infrastructure, safeguarding critical underground and concrete joints against water ingress.
Challenges
Metro stations experience persistent, heavy vibration from train transit and dynamic structural expansion or contraction. Concrete joints require water stops that can stretch and flex continuously without tearing or dislodging. Mass rapid transit systems like the NCRTC project operate under rigorous government safety and material audits. Every batch of water stops had to strictly comply with the IS:15058/2002 Indian Standard, ensuring long-term chemical, physical, and tensile durability.
Underground metro infrastructure faces immense hydrostatic pressure from groundwater. Water can easily track along smooth surfaces, causing long-term degradation of the station's concrete foundation.
Solution
Maruti supplied the 230x6mm seals with an engineered central bulb design. This bulb acts as an integrated expansion joint, effortlessly absorbing multi-directional structural movement, shear forces, and thermal expansion while maintaining a watertight seal. Our PVC water stop seals are manufactured from 100% virgin, high-grade polyvinyl chloride compounds. Each batch was meticulously tested in-house and certified to meet IS:15058/2002 benchmarks for tensile strength, elongation at break, and water absorption, ensuring a hassle-free approval process for Vaibhav Construction.
The ribbed design of our PVC seals creates a tortuous path for water. When embedded into the concrete poured by Vaibhav Construction, the multi-rib profile creates a mechanical interlock that stops high-pressure water from seeping through the construction joints.
