Monolithic drainage system designed to accept large volumes of rainwater
The RECYFIX®MONOTEC one metre long channel component is of a monolithic design where the grating is moulded as an integral part of the channel. The whole unit is made of shock resistant, virtually unbreakable polypropylene (PP) formulated to be very resistant to UV light. Complying with the requirements of EN 1433, the PP is given this UV resistance by adding just sufficient carbon black as a stabiliser so that the structural strength of the material is unaffected and a consistent appearance is maintained.
RECYFIX®MONOTEC channels are offered in two nominal grating widths of 100 and 200mm, both suitable for a loading category of up to class D400. The 100 mm channels are available in three overall heights: 230, 280 and 380 mm and provide channel cross-sections of 190.5 cm2, 245.5 cm2, and 355.5 cm2 respectively. The 100 mm channels can be arranged in a step-fall arrangement if desired that allows rainwater to cascade down to the system’s trash box. This arrangement can reduce the foundation concrete required for the job.
The largest 200 mm channel is 450 mm high, has a cross-section of 746.1 cm2 yet only weighs 16.2kg.
Optimised hydraulics of RECYFIX®MONOTEC
In 2010 Hauraton introduced FIBRETEC®, a new design of moulded slot grating on their RECYFIX®PRO range of channels. This heelsafe grating has super smooth, elliptical slots openings where the moulded bars have slightly raised triangular bosses along their outside edges. As well as providing an elegant appearance, this feature ensures surface water is directed into the slots helping eliminate any cross-flow over the grating. A grating with the same design has now been incorporated in the RECYFIX®MONOTEC which helps optimise the channels large hydraulic capacity.
The introduction of RECYFIX®MONOTEC means in any project, three different types of channel run can be specified yet the appearance of the gratings can be the same.
Marcus Reuter, HAURATON’S Managing Director explains a major benefit of the new channels, “Specifying RECYFIX®MONOTEC allows hydraulic engineers and contractors wide flexibility during the design and installation stages by reducing the number of channel runs normally required to drain a large area. The reduction means less materials being used and fewer underground excavations, all resulting in an easy and fast installation procedure”.
RECYFIX®MONOTEC channels are certified in accordance with EN 1433. The CE symbol, external monitoring and the declaration of performance are the guarantee of a maximum technical and qualitative standard.
