Industrial Waterproofing Systems for Tunnels & Underground Structures

Protecting critical infrastructure from water ingress is essential for the longevity and safety of tunnels, bridges, and underground facilities. Our industrial waterproofing range offers robust, high-performance systems tailored to withstand extreme hydrostatic pressure, structural movement, and harsh environmental conditions. Whether you are managing a new construction project or maintaining existing infrastructure, these solutions provide a reliable barrier against moisture, sulfate attack, and chemical exposure.

Key Product Features

• Sheet Membranes: High-density polyethylene (HDPE) and PVC sheet membranes offer superior tensile strength and puncture resistance, ideal for large-scale tunnel linings and basements.
• Liquid Coatings: Seamless polymer-modified cementitious and bituminous coatings ensure complete coverage over complex geometries, joints, and penetrations without seams.
• Durability & Flexibility: Engineered to accommodate structural shifts and thermal expansion while maintaining an unbroken waterproof seal over decades.
• Chemical Resistance: Formulations resistant to aggressive groundwater, sulfates, and industrial chemicals to protect concrete integrity.

Applications

These systems are widely used in metro tunnels, highway underpasses, bridge decks, parking garages, water treatment plants, and deep foundation basements. They are compatible with various concrete substrates and can be applied using standard mechanical or adhesive fixing methods, ensuring efficient installation and long-term performance in the Saudi Arabian climate.
