Our highly motivated team are fast to react to new building demands.
Our company has invaluable skills to cope with any project challenges.
SIPHONICS VERSUS TRADITIONAL ROOFING
In principle, siphonic drainage is a very simple process. Unlike traditional roof drainage, which is designed to flow part full, a siphonic system operates at full capacity, when water is sucked or siphoned from the roof down into the drain at high velocity.
Traditionally, the rainwater is collected from the roof at regular points by gravity flow. The larger the roof area is, the more numerous the points are. The risk of overloading can be an issue with large areas of drain run-off water from biulding roofs.
WORKING WITH LEADING PROFESSIONALS
Geberit HDPE discharge pipes are suitable for a multitude of application ranges in building drainage, roof drainage, in industry, in commercial or laboratory facilities, for placement in the ground, in concrete or in bridge construction.
When you discharge waste water from domestic, civic and commercial buildings, you need robust, reliable and sustainable systems. Plastic pipe systems are proven solutions for soil and waste discharge.
Drain Roof is a range of rainwater outlets and accessories. The roof drains which can be used for all types of flat roofs with bitumen or single ply roof membrane, are suitable for gravity and siphonic applications.
Why use siphonics
Several factors have to be considered to make siphonic rainwater system work effectively. Specially designed roof outlets take into account rainfall intensity rate and to design the pipework configuration to optimise performance.
You can talk to us direct or arrange your architect or contractor to organise the first phase meeting to discuss future project requirements.
The polyethylene used contains special additives which effectively protect against UV rays. The weatherproof pipes can therefore be stored outdoors for months. The pipes and fittings withstand shocks, drops, impacts or short-term pressure without breakage or permanent deformation.
