The ULMA U250 linear drainage system is made with polymer concrete . It is an ideal drainage solution for load class ratings A through C including commercial, pedestrian, parking and sport facility applications. Channels are offered in 1 meter neutral sections.
Polymer concrete presents many superior properties to traditional materials including high compressive strength, low permeability and resistance to chemicals and corrosive agents. It provides a smooth channel surface that has a near zero absorption rate which increases the flow rate. This is in comparison to concrete which has a 5-10% absorption rate. The ULMA U250 channels are resistant to 59 different chemicals. You can view the full list by clicking here.
ULMA drainage solutions tolerate seasonal freeze-thaw and can withstand temperatures at a maximum of 167°F/75°C.
Two locking bars and two screws are used per meter. Catch basins and various grate options are available to finish off your drainage system design.
