Tordera railway bridge Impermax Polyurea H Flex
Notas de ingeniería. No un blog. Railway bridge over the Tordera. Impermax Polyurea H Flex (proyectado en caliente hybrid poliurea) is the membrana nominada.
Rayston Epoxy 100 (sin disolventes epoxi imprimación) is the recorded imprimación. A geotextile is the recorded protection before ballast. Therefore the specifier writes the commercial name and the chemical type in the same sentence. Ballast is not the impermeabilización.

First, name the structural deck. Rayston Epoxy 100 (sin disolventes epoxi imprimación) is the recorded preparation. Then name Impermax Polyurea H Flex (proyectado en caliente hybrid poliurea). Catálogo 2026 lists it for bridge and viaduct decks. The job record names it as a continuous elastomeric layer with puenteo de fisuras classified as B.4.2 dynamic / A5 static.
After that, a geotextile is adhered over the membrana. Railway ballast is then laid as the track base. Do not leave the poliurea as the wearing surface under ballast. Also, do not invent a kilogram rate. Read consumo from the ficha vigente, then the calculadora.
Cómo especificar Impermax Polyurea H Flex on a railway deck
Name imprimación, proyectado en caliente hybrid poliurea, geotextile and ballast as separate lines. Keep puenteo de fisuras on the current TDS; do not invent a class. A spray photograph is not the protection clause.
See bridge decks, viaduct decks and products. Documentos stay on /documents/.

Outbound reference: EOTA.
B.4.2 / A5 is the class written on the job record. Confirm it on the ficha vigente before the specification is frozen.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the ficha vigente, then the calculadora.
