Oviedo green roof Impermax 2K
Engineer notes. Not a blog. Green roof, Regional Health Ministry, Oviedo. Oviedo green roof Impermax 2K (two-component polyurethane) is the named membrane under planting. No area is given.
Oviedo green roof Impermax 2K (two-component hot-spray polyurethane) is the membrane named on the green roof of the Regional Health Ministry building, Oviedo. Therefore the specifier writes Impermax 2K and the planted build-up in the same sentence. Magazine NUM.3 prints no area. Do not invent one. A drip-line photograph is not a root test.
Why Oviedo green roof Impermax 2K needs the root mark
Catalogue 2024 prints a certificate of resistance to root penetration on Impermax 2K, with ETA 10/0296, 25 years (W3). That mark stays on this name. An aliphatic topcoat is required where the membrane sees UV before planting. Do not move the root certificate onto a 1K balcony coat.
However, do not invent kg/m². Read the current TDS, then the calculator.
See Oviedo green roof Impermax 2K on gardened roofs, Impermax 2K and documents.
Outbound reference: EOTA — European Technical Assessments.
First, name the planted roof. Then name Oviedo green roof Impermax 2K. After that, keep the root-penetration certificate 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.
