Why Waterproofing is Critical for Infrastructure
In large-scale infrastructure projects, waterproofing is more than a protective measure. It directly impacts durability, safety, and lifecycle costs. Tunnels, reservoirs, basements, canals, and landfills constantly face water pressure and environmental stress. Without proper waterproofing, these structures can develop leaks, suffer structural damage, and incur high maintenance costs.

PVC geomembranes have become one of the most reliable solutions for these challenges. DL Millars, an established Indian manufacturer since 1929, delivers high-quality PVC geomembrane systems for infrastructure and environmental applications across India.
What is a PVC Geomembrane?
PVC geomembranes are flexible polymer sheets that block water and fluids effectively. Unlike conventional waterproofing methods, which can crack or deteriorate over time, PVC geomembranes retain their physical and chemical properties for decades. DL Millars produces PVC geomembranes in India using advanced calendaring lines and specialized polymer formulations. This ensures consistent quality, long-term durability, and reliable performance.
Compliance with Standards
DL Millars PVC geomembranes strictly follow BIS IS:15909:2020 standards, as well as international ASTM and EN standards. This compliance allows engineers to use these geomembranes in government-regulated projects under authorities such as RVNL, IRCON, and NHAI. The sheets typically come in 1.5 mm and 2.0 mm thicknesses, providing a strong yet flexible solution for demanding applications. Their design allows them to adapt to uneven surfaces, minor ground settlement, and temperature variations.
Tunnel Waterproofing Applications
Tunnel waterproofing demands high reliability. Water ingress can compromise safety and increase maintenance costs. DL Millars PVC geomembranes form the core of a multilayer waterproofing system. This system includes geotextile protection layers, geomembrane liners, water stops, injection pipes, and concrete protection. The geomembrane acts as the main water barrier, while the geotextile layer enhances puncture resistance and distributes loads.
DL Millars provides turnkey solutions for tunnels. Large panels are prefabricated to reduce field joints and prevent leaks. On-site installation uses advanced thermo-welding techniques. Technicians inspect and test every seam to guarantee long-term water tightness.
Water Containment and Reservoirs
DL Millars PVC geomembranes are widely used in water containment systems, such as reservoirs, canals, lakes, irrigation ponds, and aquaculture facilities. Seepage control is essential in these applications. PVC geomembrane liners block water loss effectively, improving operational efficiency. Their smooth surface helps maintain water quality, which is particularly important for aquaculture and agriculture.
By controlling seepage, PVC geomembranes conserve water, reduce losses, and improve system performance. These advantages make them a preferred choice for government and private water projects alike.
Environmental Protection and Waste Management
DL Millars PVC geomembranes also support environmental protection. They provide reliable solutions for landfill lining, landfill capping, and industrial waste containment. The geomembranes prevent leachate migration, protecting soil and groundwater. Combining geomembrane and geotextile layers increases chemical resistance, puncture protection, and overall system stability.
These systems ensure safe containment of industrial and municipal waste while maintaining environmental standards. Engineers and project managers rely on DL Millars geomembranes for sustainable and compliant waste management solutions.
Building Waterproofing Applications
PVC geomembranes offer excellent waterproofing for building structures. Roofs, basements, foundations, podium slabs, and underground concrete structures benefit from their durability. Compared to conventional coatings, PVC membranes resist moisture ingress, structural deterioration, and aging. Builders and engineers prefer these membranes for their long-lasting protection and adaptability to movement or stress in the building structure.
