Introduction

• Tunnel construction are

built for a life

expectancy of 100 years

• The requirements are similarly high,

particularly those on the sealing system

• From the raw material till to the

finished Waterproofing Installation

- it is a question of Quality

for a life expectancy

of 100 years

Function

of a sealing membrane

• keep the water away from the structure or out of the inner working area

• protect and assure the concrete contruction against the corrosive, chemical components of the groundwater

Requirements to the sealing system

  • watertight

• repair ability (injection)

• resistance against chemical components

• weldable by thermal means (hot air)

• safe and economic inspection for damages

(built with a very thin signal layer on one side)

• flexible, elastic ( bridge crack formations without

loosing its functioning capacity, pressure of the fresh

concrete, hydrostatic pressure, creep, temperature,

increase of tension, etc.)

Material and Funktion of AGRU Tunnel Membranes

• made of very flexible Polyethylene

• high degree of flexibility

• high stretching resistance in multiaxial directions

• high resistance against tension tears

• high degree of resistance to chemicals

• suitable for drinking water (water protection area)

• with signal layer

• various thicknesses

• tested and approved according to the

requirements of DS 853, ZTV- Ing

and other technical specifications

Structural design of DS 853

Fundamental differences are made in

underground construction work in

rock, between sealing against

pressurised water and against seepage water

• for seepage water a 2.0 mm thick membrane

• for pressurised water a 3.0 mm thick membrane

• in each case provided with a signal layer

PVC

VLDPE/ LLDPE/ FPO

For production of PVC, plasticisers are added to the vinyl chloride by a physical process (physical conjunction

"external plasticising", the flexibility of the basic material is created by adding of plasticisers to the molecule chains).

--------------------------------------------------------------------

By burning or welding, PVC causes fumes, those contains hydrochloric acid; this can lead to cauterisations of the respiratory tract; scaffolds and machines made of carbon steel begin to corrode.

----------------------------------------------------------------------

limited resistance to chemicals, depends on the composition and the temperatures

-----------------------------------------------------------------------

ageing by loss of plasticisers after thermal and/or chemical stress and as a result strong reduction of the flexibility (mono-axial and biaxial elongations are massively reduced).

mass extraction (wash out) in the event of strong water flow and water circulation

the combination of chemical compounds of ethylene copolymers (CO monomers) of varying flexibility (internal plasticisers) provides the flexibility of the basic material.

without plasticisers: do not contain any volatile or extractable components (mass extraction).

------------------------------------------------------------------

the incineration of PE does not cause any contaminants which could be hazardous to the environment

------------------------------------------------------------------

very high chemical resistance and high resistance to aggressive water

------------------------------------------------------------------

no extraction of components out of the geomembrane in the event of strong water flow and/or water circulation (internal/chemically linked plasticising)

VLDPE, FPO/TPO and PVC-P are suitable Materials.

Required Conditions for Durability are proper Formulations and professional Installation (Welding)

Project Engineers shall consider by choosing the material following facts

Long Term Water Pressure

Long Term Temperature Conditions

Composition of in situ Water

Intensity of Water Streams have to be considered

Agru Liners of VLDPE, FPO/TPO fulfils all Requirements

Liners of PVC-P are limited to Temperatures less 20°C, low water pressure Conditions without any agressive water contents

Agru Waterstop Profile

AGRU Waterstop SAA 500/6

The waterproofing of tunnel constructions is essential for the service life of the whole structure.

Modern tunnel insulations are designed to offer a possibility for repair of hollow spots or untight areas with special injection resins.

At casting joints of the inner Concrete shell waterstops are installed to create separated compartments. Integrated injection hose clamps with injection outlets at certain distances provide defined injection of resin at repair sections.

The AGRU waterstop SAA 500/6 is designed for perfect anchoring of the sealing-webs to withstanding highest backpressures.

Fulfills all requirements acc. DIN 18197, DIN 18541,EAG EDT
