General Description

Alderprufe Tuflex is a single layer cold applied geomembrane suitable for environmental protection tostructures, containments and cut-off trenches.

Alderprufe Tuflex combines excellent chemical resistancewith low flexural modulus to provide a malleable, flexiblemembrane suitable for non-smooth surfaces and factoryprefabrication to optimise on-site installation.

Alderprufe Tuflex is the ideal membrane for building protection systems and cut-off trench containment particularly on contaminated sites which would otherwiseprove too difficult or costly to develop.

Building Protection Membrane

Applied as a Gas Barrier Membrane to protect the buildingagainst the ingress of all land borne gases - Methane,Carbon Dioxide and Radon. Tuflex is laid in a single layerover a prepared site. Due to its inherent weldability and onsite quality assurance monitoring, the membrane is recommended to be laid by trained operatives certified forthe purpose. On smaller sites factory fabricated panelscan be supplied for application by others. Applied to coverthe whole of the slab area above Aldervent gas ventilationsystem if required.

All membrane penetrations (i.e. steel stanchions and service entry points) to be sealed with factory formed unitswelded to the membrane on site.

At all points where the membrane passes through loadbearing walls, Aldercourse Tuflex DPC or GRA DPC isinstalled and welded to the overlaying Tuflex membrane.

Membrane Protection

Protect finished membrane with Geotex or Alderway protection mats if following trades are erecting steel fabrication for slab reinforcement.

All punctures to be repaired by a minimum overlap of150mm.

Cut-off Trench Containment

Alderprufe Tuflex has been successfully installed up to 8metres deep as a vertical barrier to contain contaminantsand gases on brown fields sites and around landfill.

Installed by accredited contractors.

Bespoke systems have been designed to suit site specificparameters.

Trilaminate membranes with exceptionally high punctureresistance are available.

Cut-off trenches for contaminant control, with large volume gas and liquid dispersal properties, are possible,utilising Aldervent Geogrid, Geovoid, or Geocell systems.(see separate data sheets.)

Puncture ResistanceTruncated Cone

Alderprufe Tuflex, when placed under load on uneven orrocky substrates, has an exceptionally high punctureresistance. It even exceeds the specifications of GRItest method GM - 3 and possesses the highest punctureresistance of all geomembrane materials measured bythis test.

Alderprufe Tuflex readily conforms to projections anddeforms easily when under static load. Stresses areevenly distributed throughout the materialʼs structureas it deforms thus allowing the membrane to maintainits “barrier” properties when subjected to both shortand long term static loads.

Alderprufe Tuflex possesses outstanding environmentalstress crack resistance compared to other materials.Alderprufe Tuflex also retains its flexibility at lowtemperatures and does not become brittle even at attemperatures as low as -40oC. This feature is particularlyimportant as it enables the Geomembrane to be handledor installed during severe weather conditions or at highaltitude.

The friction angle of Alderprufe Tuflex measured by thismethod is higher than that of all the commonly usedsmooth geomembrane materials. This allows theconstruction of steeper side slopes, increasing thecapacity and, in the case of landfills, speeding up wastesettlement.

The demands made on Alderprufe Tuflex in landfill, watercontainment or pollution control are considerable. Theflexibility of Alderprufe Tuflex is due to the polymericstructure of the resin.

Alderprufe Tuflex possess exceptional flexibility, tearand puncture resistance qualities for all water containment projects, even at very low temperatures.

Ornamental ponds and water storage lakes used inlandscaping and irrigation projects utilise the specialattributes of the Alderprufe Tuflex geomembrane.

Alderprufe Tuflexgeomembranes are used asliners and capping tocontain both the gas andliquids produced by a landfilloperation. The multiaxialstrain qualities of AlderprufeTuflex are so good that thegeomembrane will resist outof plane forces caused bysubsidence which occurswith differential wasteconsolidation and unstablesite substrates

The flexibility of AlderprufeTuflex geomembranes ensuresthat most ponds, ditches,lagoons, lakes and dams can belined including those with inherently complex shapes.

The exceptionally wide seamingtemperature window ensures areliable weld is achieved in mostweather conditions. Fluctuationsin temperature are not as criticalas they are with other geomembranes.

Coefficient of Thermal Expansion

Thermal Ageing tests of AlderprufeTuflex Geomembranes

Large Scale Multiaxial Stress-Strain Test

One of the most noteworthy features of AlderprufeTuflex is the inherent ability to elongate when subjectedto out of plane stresses. Localised deformation typicallyoccurs in a landfill capping as the solid waste subsidesor under slabs as piled sites are subject to groundsubsidence.

The outstanding multiaxial performance of AlderprufeTuflex is most beneficial in these applications where ahigh degree of subsidence is anticipated.

the excellent multiaxial elongation demonstrated byAlderprufe Tuflex indicates that it can accommodatemore differential settlement than other membranes.

Alderprufe Tuflex has an unusually low coefficient ofthermal expansion (CLTE), as little as half that of someother geomembranes. During installation, AlderprufeTuflex geomembrane does not expand or contract asmuch and therefore forms fewer and smaller wrinkles.Also, placement of cover material may be simplifiedsince the liner has a better tendency to lay flat. Thesefactors lead to easier and higher quality installations.

The high melting point of AlderprufeTuflex makes it particularly suitablefor environments such as blackliquor effluent ponds with operatingtemperatures of 700C and solarponds where liners must withstandtemperatures fluctuating from 100 - 800C. Alderprufe tuflex maintainsits mechanical properties across anunusually broad range oftemperatures.
