.Waterproofing Project
Waterproofing of Railway Bridge over the Tordera River
Location:
Blanes – Malgrat de Mar (Barcelona)
System used:
Waterproofing system with Impermax Polyurea H Flex
Storm Gloria rendered the old railway bridge over the Tordera River, connecting the towns of Blanes and Malgrat de Mar, completely unusable. The new infrastructure, spanning 221.3 metres, was rebuilt with an investment exceeding 8.6 million euros. As part of the works, the entire bridge deck was waterproofed to protect the structure from water infiltration and deterioration caused by continuous railway traffic and harsh weather conditions.
How we do it:
- Surface preparation and priming
- Cleaning and preparation of the structural substrate using EPOXY 100 PRIMER.
- Waterproofing
- Application of IMPERMAX POLYUREA H FLEX elastomeric membrane, a highly flexible hot-spray polyurea. It provides a continuous, seamless layer with excellent crack-bridging capacity (classified as B.4.2 dynamic / A5 static).
- System protection
- A geotextile layer was adhered over the membrane as protection. Afterwards, railway ballast was directly laid over the system, serving as the base for the track installation.
