Mataki – in the roofing business since 1904. Mataki has been supplying waterproof roofing materials in one form or another for nearly a century, and now markets a complete range of advanced membrane sys- tems and roofing products. Mataki products are developed and manufactured at our facilities in Sweden. We hold an ISO 9001 quality certificate. The Trelleborg Group. Mataki is a division of Trelleborg Building Systems AB, one of the business areas of the Trelleborg Group. Trelle- borg develops and manufactures products which in various ways contri- bute to a better indoor and outdoor environment. Operations are ISO 9001 certified, and an environmental manage- ment system is currently being developed with a view to ISO 14001 certification. Substantial resources are devoted to research and develop- ment. Trelleborg’s expert knowledge of rubber and bitumen based pro- ducts, and its experience in their application, make the Group unique of its kind in the world.

It is suitable for industrial, urban and rural environments – in other words, everywhere.

By combining standing properties which was also free from halogens polyester and glass fibre in the reinforcement, we have (including chlorine) and other undesirable substances. given it unique tear strength and dimensional stability. But now we have Mataki Elastofol – a roofing In addition, we have put an extra protective layer on membrane based on TPE-modified bitumen, which is the outside. We did not get a patent on Mataki Elastofol a proven material that has been used for many years. for nothing!

What more can you ask? Our product development is focused on minimum environmental impact, and that applies very much to Mataki Elastofol. Environment-friendly production aims at preventing pollution of water, air or soil. Alter or extend without problems The ageing-resistant properties of Mataki Elastofol make it possible to splice new material to old by hot-air torching, so repairs and exten- sions in connection with alterations are easily made. Skylights, lantern lights, pipes and other fittings can be installed later with no trouble. So alterations and extensions are not a problem. Because Mataki Elastofol is a roofing membrane with an optimised application system, it can be laid quickly; if an old roof starts leaking, it can be repaired without delay. This reduces costs as well as the risk of damage caused by damp, which could interfere with production in industry or make it necessary to evacuate tenants. Minimum maintenance The ability of Mataki Elastofol to resist weather, wind, mechanical stresses, movement, UV radia- tion and thermo-oxidative degradation minimises the need for maintenance. Mataki Elastofol is a technically advanced system compared to many other roofing systems, which often require regular inspection. Mataki Elastofol is the closest you can get to a maintenance-free roof. The excellent splicing properties of Mataki Elastofol make it easy to repair or extend, even where the material is old. Alterations to roofs need no longer be a headache. Praised by roofing contractors Studies indicate that most cases of damage to roofs are caused by faulty installation, which can often be blamed on non-user-friendly systems or materials. The unique properties of Mataki Elastofol, with its safe and flexible splicing sys- tem, eliminate such problems.

A complete system with everything you need Mataki Elastofol is a comprehensive system that can be laid on substrates of wood, mineral wool, cellular plastic, metal, concrete, lightweight concrete or on top of old waterproofing courses. A complete range of ingenious fastening compo- nents meets the requirements of most applica- tions. The mechanical fastening system makes it qui- te feasible to lay Mataki Elastofol even if the sub- strate is not totally dry; moisture is not trapped under the membrane. The Mataki Elastofol system comprises various types of fasteners specially designed for mechanical fixing to steel, concrete and other substrates. The patented fasteners are made of stout polypropylene or polyamide.

We have eliminated weak points by developing a customised range of fittings for Mataki Elastofol – pipes, outlets, etc. – with excellent adhesion to the membrane.
