Crack-bridging class, stated in the cold
Engineer notes. Not a blog. Write the crack-bridging class at the climate of the deck. A figure taken only at 23 °C is not the winter roof. Therefore the specifier states the class in the cold.
Why the crack-bridging class is a climate statement
Airport roofs in the waterproofing catalogue are written for decks that exceed 50 °C in summer. They also fall below 0 °C in winter. The membrane has to absorb expansion and contraction without tearing. That is a crack-bridging class, not a colour.
Impermax Polyurea H Flex (hot-spray hybrid polyurea) is the Catalogue 2024 membrane for bridge decks and other structures with movement. EAD-030675 21/0740 sits on that name. Pedestrian roofs, balconies and terraces schedule Impermax (one-component moisture-cured polyurethane, 1K PU) or Impermax Cold Polyurea where the catalogue names them.
However, a self-levelling floor body is a different liquid. Pavifloor / Pavisoft (resin floor body) is a different liquid and is not this clause. Also, do not print a kilogram rate here.
How to write the class
First, name the membrane. Then name the temperature of the class. After that, send the reader to the current TDS for thickness. In addition, keep consumption on the sheet, then the calculator.
See Impermax Polyurea H Flex, bridge decks, and airport roofs. Documents stay on /documents/.
Outbound reference: EOTA — ETAGs and EADs.
A 23 °C class on a winter airport roof is the wrong number. Write the cold class from the current sheet.
Therefore the current TDS remains the source for mix ratio, overcoat and consumption. Then the calculator sizes the area. However, a number invented here would be a specification error. In addition, the application page is the schedule. First name the exposure. Next name the commercial product and the chemical type in the same sentence. After that, open documents. Also keep the finish on the same clause as the body. A sample, a colour or a photograph does not replace that sentence.
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.
