The Geberit ProPlanner software

Geberit Pluvia is the leading siphonic roof drainage system used for over

30 years around the world in over 80,000 installations to drain 80 million

sq metres through 300,000 outlets. Architects, Consultants and

Contractors have chosen the system for some of the most prestigious

and ground breaking building designs due to the freedom and flexibility it

provides. Pluvia uses the ingenious gravity induced vacuum principle to

create a siphonic action, which allows the complete drainage of a roof

area with smaller diameter pipes than used in a conventional gravity

system. Geberit Siphonic roof systems are widely used in the commercial

and industrial sector for all roofs.

Geberit Pluvia Advantages

■ New architectural flexibility in building and use

■ No slope in pipework required

■ Less underground pipes

■ Less sitework

■ Fewer pipes and fittings

■ Reduced pipe dimensions

■ Less space required

■ Self cleaning action

■ A simple and speedy fastening system.

The Geberit Pluvia System is fully approved by the

BBA. This includes outlets, pipes & fittings, and the

dedicated design software.

The product range includes outlets to suit most roof designs and

finishes, with a comprehensive range of contact foils to suit the majority

of roof membrane materials currently on the market. RIBA approved CPD

seminars are available. Please contact Geberit for more information.

Siphonic System

■ Large spans between beams can be bridged

■ Fewer brackets on roof structures

■ Pre-assembly on the floor is possible: alignment of clamps on the rail, or alignment of clamps and of HDPE pipes on the rail

■ The clamps are conveniently secured with wedges

■ Only very simple tools are required for the assembly of the system.

■ The system overcomes fixing constraints on steel profile roofs

■ The clearance required to install insulation against condensation is accounted for in the design

■ The forces associated with changes in length as a result of temperature fluctuations are absorbed by the rail fastening.

The Geberit Pluvia Outlets

Developed for all types of roof structures. Due to the different discharge rates of

the outlets (6 l/s, 12 l/s or 25 l/s) an economical layout of the roof drainage system

can be reached. The wide range of contact sheets and accessories allows

connection to most roof finishes.

Pipes and fittings

Geberit’s HDPE range of pipes and fittings complement the Pluvia outlet to provide

a total drainage solution. Geberit HDPE is available in a variety of diameters from

40mm - 315mm, and can be jointed in a variety of different methods including

electrofusion, butt welding and mechanical coupling. The outstanding material

characteristics of Geberit HDPE allow specifiers and contractors to design and

prefabricate pipe runs away from the site of the installation. Pipe runs can be

created in a safe, clean environment ensuring secure and accurate fabrication as

well as considerable material and labour savings.

The Geberit Pluvia rail fixing system

The Geberit Pluvia fastening system was developed for the installation of

exposed, horizontal roof drainage piping. The expansion and contraction of the

piping, which occur after installation are absorbed by the system itself.

For this purpose, all mechanical forces are transmitted to the square steel rail

routed parallel to the pipe.
