SOPREMA speaks bridge decks
Discover our specialist bridge deck waterproofing solutions designed to protect critical infrastructure from water ingress, environmental exposure and long-term deterioration.
Bridge Deck Waterproofing Systems
Bridge deck waterproofing plays a vital role in protecting transport infrastructure from water ingress and the long-term effects of traffic loading, environmental exposure, and structural movement. Selecting an appropriate waterproofing system helps safeguard bridge structures, supports long-term durability, and contributes to effective asset management.
SOPREMA provides liquid-applied bridge deck waterproofing systems for highways, rail infrastructure, pedestrian bridges, and other civil engineering structures.
Our technical team collaborates with designers, engineers, contractors, and infrastructure owners to provide specification guidance and technical support throughout every stage of a project.
Why Liquid-Applied Waterproofing?
Liquid-applied waterproofing systems are widely specified for bridge deck applications because they cure in place to form a continuous waterproof membrane directly bonded to the prepared substrate.
Unlike sheet membranes, liquid-applied systems do not contain laps within the waterproof layer, allowing the membrane to follow complex bridge geometries, penetrations and detailing while maintaining continuity across the deck.
Selection of any waterproofing system should always consider the project requirements, bridge design and specification.

FAQs
Bridge deck waterproofing is a protective membrane applied to the bridge deck before the wearing course to help prevent water ingress into the structure.
Water can contribute to corrosion, concrete deterioration, and increased maintenance requirements. Waterproofing helps protect the bridge structure from moisture ingress.
Liquid-applied waterproofing systems cure in place to form a seamless membrane directly bonded to the prepared substrate.
Some liquid-applied systems are designed for use on both concrete and steel bridge decks. Suitability should always be confirmed against the project specification.
Bridge waterproofing systems may be independently assessed against recognised standards and certification schemes, including EAD 030675-00-0107 and BBA certification where applicable.
Depending on the system, application may be carried out manually or using spray equipment by trained installers.
Repair methods depend on the waterproofing system and the nature of the damage. Project-specific technical guidance should always be followed.
