Elastopastomeric polymer-bitumen waterproofing membrane suitable for use under hot premix.
Index Testudo is manufactured from distilled bitumen which is modified with elastomers and plastomers and then reinforced with a non-woven continuous extruded spun bond polyesterfabric, which is rot proof. It offers increased elongation properties and is resistant to heat ageing, and puncture resistant. The compound is a mixture of distilled bitumen, plastomers and elastomers which give the membrane excellent durability and flexibility at low temperatures.
Index Testudo is manufactured with a sacrificial FLAMINA polyethylene film on the lower membrane face, which prevents sticking when the membrane is being stored and which contracts and melts quickly when subjected to heat during installation. The lower face is embossed with small squares, which assist in the rapid burn off of the Flamina and helps vapour diffusion as well as indicating the correct melting point for the adhesion to the substrate. Index membranes are unique in that they are treated with serigraph talc which prevents sticking when unrolling the membrane during laying and provides a prepared surface for the application of an aluminium reflective coating to the upper membrane surface.
Due to the excellent heat & abrasion resistance and elongation properties of Index Testudo, it is used to solve difficult site waterproofing problems associated with industrial and domestic waterproofing.
These include: flat, sloping and pitched roofs, reinforced cast concrete deck, pre-fabricated concrete deck, metal and timber deck, terraces, under slating or under tiling, foundations, anti-earthquake foundations, car parks, waterworks, environmental work and acid resistant protection, with or without thermal insulation as well as for renovation purposes.
