Underground car park Polyurea H Flex at Jorge Newbery
Engineer notes. Not a blog. An underground car park Polyurea H Flex is a named hybrid on a buried deck. It is not a roof 1K coat.
Cite an underground car park Polyurea H Flex on the membrane that carries the movement mark. Krypton magazine NUM.5 (October 2025) waterproofs the underground car park at Jorge Newbery Metropolitan Airport, Buenos Aires, at 11,000 m², on land reclaimed from the Río de la Plata. Primer Epoxy 100 (two-component epoxy primer) is the primer on concrete. Impermax Polyurea H Flex (hot-spray hybrid polyurea) is the membrane. Therefore the specifier does not borrow a pedestrian-terrace 1K.
What underground car park Polyurea H Flex actually covers
Catalogue 2024 prints EAD-030675 21/0740 on Impermax Polyurea H Flex for decks that move. Keep those citations on H Flex. Do not move ETA 06/0263 from Impermax (one-component moisture-cured polyurethane, 1K PU) onto this buried park. Do not move WRAS from Polyurea Rayston (pure polyurea) either.
However, an underground park is not a rooftop car park with UV as the first exposure. An aliphatic finish stays on the current TDS where the catalogue names it. Also, do not print a kilogram rate on this note. Kryptanate M (polyaspartic) is a different parking-floor body. Rayston Floor PUA 30 PARK is a different OS10 floor. Keep them off this waterproofing card.
How to write an underground car park Polyurea H Flex
First, name the buried deck and the traffic. Then name Primer Epoxy 100 and Impermax Polyurea H Flex in the same sentence. After that, send the reader to documents. In addition, size the area on the calculator once the sheet is read.
See Impermax Polyurea H Flex, car park roofs, indoor and outdoor parking and documents. Area is sized on the calculator.
Outbound reference: EOTA — ETAGs and EADs.
A buried slab is not a cool roof. Keep H Flex on the underground park. Keep 1K names on the roofs that carry them.
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.
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.
