BRIDGE FILTER DRAIN:
Saczek_Odwadniajacy.gif

Bridge filter drain - is intended for local water drainage from waterproof membrane level on flat surfaces of the traffic structures and collecting water penetrating the bridge deck surfacing on the waterproof membrane. The bridge filter drain may be used on all types of road and railway structures.

The filter drain is made of glass resin laminate. It provides resistance to aggressive chemicals and variable temperature -35°C to +230°C.

The filter drain consists of two components: an outlet with stabilizing fins and a mesh. The outlet with fins includes Ø200 mm disk and Ø43 mm outflow pipe. Total filter drain height is 80 mm, including 40 mm outflow pipe. Mesh with 120 mm diameter features twenty Ø6 mm holes on both ends.

Installation:

The outflow pipe is extended with PVC K 50x 1,8 pipe to the length corresponding to the deck slab thickness. A PVC pipe hub must be seated in a drip tube. The filter drain must be fixed to the deck slab before casting. For renovated structures, the filter drain must be fixed in a drilled hole with a joint filled with a non-shrinking mortar.
