The slotted pipes are designed for the discharge of the rain water and oil substances (leakage) from the reinforced surfaces, i.e. dewatering the most demanding roads, motorways, class I roads, tunnels, airports, parking spaces, etc. The slotted pipes of profile II are suitable into the locations with high rain rate with the condition of the lowest bending. They are made only in descend-free variant. The elements of profile II-1 (with interupted slot) are dimensioned for the classes of transport load D400, E600 and F900. Interrupted inflow slot guarantees the element stability even during transverse travel. The elements of profile I with continual slot are not designed for transverse travel. The system comprises of four basic elements: the slotted pipe with interupted slot length 4 m without interior decline, complete drain piece including the plastic lid (alloy mesh), sludge basket and rectification cone, cleaning piece including the pastic lid (alloy mesh), plug.

Profile II slot drains are suitable for draining rainwater contaminated with small quantities of oil products (drips) from surfaced areas such as high-capacity traffic structures (motorways, dual carriageways, main roads, tunnels, runways, lay-bys, large parking lots, etc.). Profile II slot drains are suitable for applications with large amounts of rainfall and where shallow depth is required. They are only available with no internal gradient. Profile II-0 slot drains (continuous slot) are designed for D400 class traffic load and no transversal vehicle travel.
