Colmenar M-40 bridge Impermax Polyurea H Flex
Engineer notes. Not a blog. 6,000 m² on the M-40 Colmenar junction. Impermax Polyurea H Flex (hot-spray hybrid polyurea) is the named bridge-deck membrane.
Impermax Polyurea H Flex (hot-spray hybrid polyurea) is the membrane named on the 6,000 m² new bridge at the Colmenar junction over the M-40. Therefore the specifier writes the commercial name and the chemical type in the same sentence. The previous deck was demolished after corrosion from deficient waterproofing. This is a complete kit: primer, membrane, protective coat.
Why Impermax Polyurea H Flex sits on a moving deck
Catalogue 2024 prints a CE mark for bridge-deck waterproofing and ETA EAD-030675-00-0107 (nº 21/0740) on Impermax Polyurea H Flex. The magazine adds a 25-year ETE for bridge decks issued by the Eduardo Torroja Institute. Hot-spray, extra-fast cure. Robot application is a method note, not a different resin.
However, a slow floor hybrid is not this membrane. Also, do not invent kg/m². Read the current TDS, then the calculator.
See Impermax Polyurea H Flex on bridge decks, Impermax Polyurea H Flex and documents.
Outbound reference: EOTA — ETAGs and EADs.
First, name the movement. Then name Impermax Polyurea H Flex. After that, keep the protective coat on the same clause.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the current sheet, then the calculator.
