The ULMA Architectural Solutions drainage system has been designed and tested under the strictest premises of EN1433 STANDARD, following the construction details set out in these installation instructions.

The design of the deck adjoining the concrete block/channel unit (concrete, asphalt or paving stone) must be endowed with the expansion and retraction joints required to prevent any tangential or perpendicular strain on the concrete block and channel unit. In line with the construction details of the deck, the sizing of said joints will be decided by the Project Management or designer.

The illustrations below show what the appropriate installed section should be for each flooring type and type of load as well as the recommended construction details.
