Polyurea Rayston Fast containment on vertical tanks
Engineer notes. Not a blog. Polyurea Rayston Fast containment is a named pure polyurea. It is not H Flex and not a 1K roof.
Specify Polyurea Rayston Fast containment when sagging on the wall is the risk. Polyurea Rayston Fast (ultra-fast 100% pure polyurea) is written for concrete waterproofing on vertical areas and water tanks containing aggressive chemicals. Catalogue 2024 names waterproofing of containment basins in the Netherlands at 1,500 m². Therefore the specifier writes commercial name and chemical type in the same sentence.
What Polyurea Rayston Fast containment actually is
European legislation requires that containment basins remain watertight for the expected discharge time. Spills damage concrete and filter through it. Catalogue 2024 lists Polyurea Rayston Fast, Impermax Cold Polyurea Supreme (solvent-free two-component polyurea) and Krypton ProLine CH55 on that page. Fast curing also allows an abrasive finish by overspraying a top layer of this product. Keep that sentence on Fast. Do not move EAD-030675 21/0740 from Impermax Polyurea H Flex onto this bund.
However, a bund is not a drinking-water tank. WRAS stays on Polyurea Rayston where the exposure is potable. Also, do not invent kg/m². Read thickness from the current TDS, then the calculator.
How to write Polyurea Rayston Fast containment
First, name the vertical tank or the secondary basin and the chemical. Then name Polyurea Rayston Fast (ultra-fast 100% pure polyurea). After that, name Primer Epoxy Plus where the catalogue lists it. In addition, size the area on the calculator once the sheet is read.
See Polyurea Rayston Fast, primary and secondary liquid containment, oil and gas / petrochemical and documents. Area is sized on the calculator.
Outbound reference: EOTA — European Technical Assessments.
A yellow platform is not a roof. Keep Polyurea Rayston Fast containment on the chemical basin.
Therefore mix ratio stays on the sheet. First name the vertical. Next name Fast. After that open documents. Also keep H Flex off this 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.
