2 AGRU - Competence in Plastics 2 AGRU - Kunststofftechnik GmbH Tunnel construction are built for a life expectancy of 100 years Introduction 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

3 AGRU - Competence in Plastics 3 AGRU - Kunststofftechnik GmbH keep the water away from the structure or out of the inner working area Function of a sealing membrane protect and assure the concrete contruction against the corrosive, chemical components of the groundwater for a life expectancy of 100 years

4 AGRU - Competence in Plastics 4 AGRU - Kunststofftechnik GmbH watertight Requirements to the sealing system 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) 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.) flexible, elastic ( bridge crack formations without loosing its functioning capacity, pressure of the fresh concrete, hydrostatic pressure, creep, temperature, increase of tension, etc.) repair ability (injection)

5 AGRU - Competence in Plastics 5 AGRU - Kunststofftechnik GmbH 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

6 AGRU - Competence in Plastics 6 AGRU - Kunststofftechnik GmbH Structural design of DS 853 for seepage water a 2.0 mm thick membrane in each case provided with a signal layer for pressurised water a 3.0 mm thick membrane Fundamental differences are made in underground construction work in rock, between sealing against pressurised water and against seepage water

7 AGRU - Competence in Plastics 7 AGRU - Kunststofftechnik GmbH Aging of Polyethylene Lifetime of AGRU PE Membranes

9 AGRU - Competence in Plastics 9 AGRU - Kunststofftechnik GmbH Comparison of LLDPE (VLDPE, FPO) vs PVC for Tunnels 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) 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 Source: Tiefbau 2/1999, Kunststoffe- Plastics 4/1981, Die Kunststoffe und ihre Eigenschaften (4.
