Geberit HDPEThe Drainage System

Diameters from 32 mm up to 315 mm

Geberit HDPE is the total solution

for all types of drainage including

above ground, below ground and

chemical waste. It provides the

appropriate solution for every requi-

rement: whether in residential or

industrial construction, for laborato-

ries, conventionally installed or pre-

fabricated, embedded in concrete

or underground.

Geberit HDPE pipes are tempered.

Therefore tensions caused by the

manufacturing no longer exist.

Subsequent dimensional changes

do not occur.

The pipes and a wide range of fit-

tings are available in sizes ranging

from diameter 32 mm to 315 mm.

The variety of fittings and jointing

methods ensure ease of installation

in any application, allowing innovati-

ve design, compatible with any buil-

ding.

Geberit HDPE: every connection is possible

The ring seal socket

Space-saving connection for

pipeline elements or appliances

connections that are individually

prefabricated.

The electroweld sleeve coupling

is the ideal connection on-site, for

subsequent changes or wherever

access is not easy.

The expansion socket

has proven itself for compensation

of thermal expansion in vertical or

horizontal installations.

The screw-threaded joint

is still a favourite detachable

connection.

The flange

a connection element for containers

and apparatuses.

The butt weld

The simplest space-saving connection

is the butt weld. The connection can

either be made by using the welding

plate only (up to dimension of 70 mm)

or the full set of a welding machine.

Geberit HDPE: outstanding material characteristicsThe inherent properties of high density polyethylene ensure that Geberit HDPE is a flexible, hard wearing and durable system

to suit almost any drainage application.

Quality

Severe internal and external controls by independent testing institutes secure perfect quality.

Resistance to extremes of temperature

Geberit HDPE can be safely used as waste pipe for temperatures of up to 80°C. Temperatures of

up to 100°C are permissible for short periods (e.g. surges of steam). The system is equally suited

for freezing temperatures and adapts elastically to cope with expansion, remaining completely

intact and undamaged after thawing.

Licensed Geberit tempering process

Geberit HDPE pipes undergo a licensed annealing process in hot water to reduce inherent tensile

stresses created during manufacture. This process ensures long-term joint integrity, as thermal

expansion and reversion are reduced compared with untreated pipes.

Impact resistance

Geberit HDPE is unbreakable at room temperature and offers excellent impact resistance even at

temperatures of – 40°C, thus meeting the requirements for drainage systems.

Chemical resistance

Geberit HDPE also offers considerable resistance to chemicals, because of its paraffin structure.

The system is insoluble in all inorganic or organic solutions at 20°C.

Crush resistance & flexibility

The flexibility of Geberit HDPE guarantees crush resistance and superior performance in applications

where pipes pass through expansion joints or are subject to traffic vibration.

Resistance to abrasion

Drainage systems are increasingly misused for "refuse chutes”. Hence a pipe’s resistance to abra-

sion is a particularly important factor for branch pipes, soil stacks and ground pipes. HDPE is very

resistant to abrasion, its extra thick walls offer superior protection from both internal and external

abrasion.

Lightweight

Geberit HDPE combines toughness and durability with the advantage of being lightweight.

Manual butt welding

The welding plate is especially suitable for welding dimensions up to ø 75 mm.

Due to its light weight it can easily be used on-site.

Machine butt welding

The butt welding machines Media and Universal are for dimensions from

50 – 160 mm (315 mm respectively). They are especially suitable for prefabri-

cation off site. The light-weight properties of the system allow specifiers and

contractors to design and build pipe runs away from a construction site.

Electrowelding

The Geberit electrofusion machine is ideal for use on construction site to create

a fast, simple and reliable connection. Electroweld sleeve couplings are availa-

ble from ø 40 to 315 mm.

The processing

Building drainage

Geberit HDPE can be used in installations in apartment buildings, industry and

laboratories. The wide range of jointing methods available for use ensures that

Geberit HDPE provides a solution for any application and guarantees that the

installation is easy and quick.

Installation in concrete

The flexibility, the easy processing and the abrasion resistance of the Geberit

HDPE drainage system make it ideal for using the system in concrete.

Underground drainage

Like in domestic drainage systems, the choice of the material is also crucial for

installation underground. The resistance to abrasion – internal and external, as

well as the crush resistance and flexibility enable to lay the Geberit HDPE

system in the ground.

The application

The innovative soil and waste

With the Sovent fitting, venting can

be managed easily by using one fit-

ting on each floor level. An additio-

nal ventilation pipe is not necessary

Conventional ventilated system

Each sanitary fitting has to be con-

nected to an additional vent pipe.

This means more installation time,

more material and larger pipe ducts.

Performance of the Sovent aerator fitting

Due to the formation of a hydraulic plug in the stack by the inflowing water from a

branch, conventional stacks very easily are overloaded with negative pressures,

exceeding the tolerable limits and traps losing their water seal.Comparison of the flow characteristics

The aerator fitting is designed to:

■ prevent the formation of a plug of water in the stack by the lateral

water-flow from the branch

■ mix efficiently the waste flowing in the branches with the water/air-flow in the

stack

■ ensure the venting action to the branch pipes

■ limit velocity of both liquid and air in the stack

■ avoid the penetration of any splash water or foam into the branches

■ offer versatile jointing possibilities in one single fitting

Geberit Pluvia System

What is Geberit Pluvia?

The Geberit Pluvia roof drainage

system is based on the ingenious

gravity-induced vacuum principle. It

consists of roof outlets, pipes and

fittings made of Geberit HDPE, an

engineered fastening system and a

professional support package. By

syphonic action, Geberit Pluvia

allows the complete drainage of a

roof without the requirement of a

slope in the pipework.

Geberit Pluvia advantages

■ new architectural flexibility in

building and use

■ no slope of pipework required

■ underground pipes

■ Iess sitework

■ fewer pipes and fittings

■ reduced pipe dimensions

■ Iess space required

■ self-cleaning action

■ a simple and speedy fastening

system

Geberit Pluvia® – the system

Conventional system with: ■ sloped collecting lines

■ numerous stack lines

■ extensive groundwork

Geberit Pluvia System with: ■ horizontal collecting lines

■ few stack lines

■ minimal groundwork

■ no slope

The Geberit Pluvia outlets are developed for all types of roof structures. Due

to the different discharge rates of the outlets (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 to connect with every roof material. The Geberit

Pluvia outlets can also be transformed into emergency outlets with an additio-

nal installation kit.

The Geberit HDPE range of pipes and fittings is the ideal system to meet

the requirements of the Pluvia roof drainage system. Due to its outstanding

material characteristics Geberit HDPE is especially suitable for prefabrication.

The fastening system

The Geberit Pluvia fastening system was developed for the installation of expo-

sed horizontal roof drainage piping.

The expansions and contractions of the pipes, that occur after installation, are

absorbed by the system itself. For this purpose, all mechanical forces are trans-

mitted to the square steel rail routed parallel to the pipe.

Fastening system features

■ Large spans between beams can be bridged in bay structures.

■ Fewer fasteners on roof structres.

■ Pre-assembly on the bay floor is possible:

– alignment of clamps on the rail, or

– alignment of clamps and of HDPE pipe on the rail

■ The clamps are conveniently secured with wedges.

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