Channels irrigation Impermax ST on frost-thaw concrete

Engineer notes. Not a blog. Channels irrigation Impermax ST are a seamless lining for transported water. They are not a roof terrace.
Write channels irrigation Impermax ST against frost/thaw, not against a pedestrian colour. Impermax ST (semi-thixotropic aromatic polyurethane) is the 1K Catalogue 2024 lists for roofs, terraces, canals, reservoirs and stands. The waterproofing catalogue names channels in Italy at 2,000 m² and in Madrid at 200 m². Therefore the specifier writes commercial name and chemical type in the same sentence.
What channels irrigation Impermax ST actually need
In extreme climates, frost in winter and high temperatures in summer degrade the outer concrete of channels and irrigation ditches. Scheduled periods without water make the damage worse. Cracks and broken joins then leak when the channel is used. Catalogue 2024 also lists Polyurea Rayston (pure polyurea) and Impermax Cold Polyurea ST (semi-thixotropic cold polyurea, ETE 17/0509) on that page. Keep the thixotropic names on pitched or vertical concrete. Do not borrow a self-levelling floor body.
However, an irrigation ditch is not a drinking-water reservoir. WRAS and Directive 98/83/CE stay on the potable cards. Also, do not invent kg/m². Read consumption from the current TDS, then the calculator.
How to specify channels irrigation Impermax ST
First, name transported water and the frost/thaw cycle. Then name Impermax ST (semi-thixotropic aromatic polyurethane) or Impermax Cold Polyurea ST as the catalogue lists them. After that, name the primer on the current sheet. In addition, size the area on the calculator once the sheet is read.
See Impermax ST, Impermax Cold Polyurea ST, channels and irrigation ditches and documents. Area is sized on the calculator.
Outbound reference: EOTA.
A lock photograph is not a sports court. Keep channels irrigation Impermax ST on the water channel.
Therefore the current TDS remains the source for mix and overcoat. 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.
