The ULMA D100 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 sports applications. Channels are offered in 1 meter sections. Locking system consists of two locking bars and two screws per section. Suitable for neutral or cascade installation to collect rainwater.
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 D100 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.
