III profile
III-PROFILE SLOT DRAINS

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 profile elements III are placed in the areas with extreme hydrological potential. They are made only in descend-free variant. Profile III-0 (with continual slot) is dimensioned solely for transport load class D400 and it is not used for transverse travel. The slotted pipes of profile III-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 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 III 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 III slot drains are designed for locations with extreme rainfal. They are only available with no internal gradient. Profile III-0 slot drains (continuous slot) are designed for D400 class traffic load and no transversal vehicle travel.
