Onduline: Roofing and waterproofing experts

Turkey-based Onduline Avrasya produce a wide range of roofing and waterproofing systems including; Onduline HR, Onduvilla roofing systems, Isoline and clay tiles roofing system, Bituline waterproofing system and Fondaline damp-proofing system.

“During our visits to the African countries, we are impressed by the business opportunities presented by the continent and also the number of people who are interested with our product line,” says Jean Akmansoy, export manager.

The company, which added the markets of the African continent to its area of operations at the beginning of 2016, has already secured several projects in the region.

“The region presents numerous opportunities to replace old asbestos roofs with asbestos-free roofing sheets such as our Onduline HR sheets and Onduvilla bituminous and lightweight roofing tiles. Our roofing line is Eco- responsible, waterproof, has thermal and acoustic comfort and it is easy to apply.

Onduline offers roofing solutions to a wide range of buildings including Residential, Commercial Buildings and Resorts, Agricultural, Public Access Buildings, Leisure housing and DIY projects and are used in more then 120 countries around the world.

Their  Isoline under tile system is also very attractive with the use of trendy clay tiles in today’s housing in the African countries and as the use of APP (atactic polypropylene) or SBS (styrene butadiene styrene) modified Bituline waterproofing membranes is a requirement in all new construction projects.

We have encountered vast demand from Benin, Burundi, Cameroun, Congo DR, Ivory Coast, Egypt, Ethiopia, Gabon, Ghana, Guiné Conakry, Kenya, Liberia, Libya, Madagaskar, Morocco, Niger, Rwanda, Sierra Leone, South Africa, Sudan, Tanzania, Tchad, Tunisia, Uganda, Zambia in housing and industrial projects. “All our products are new for the African market,” Akmansoy adds.

ONDULINE HR –Roofing sheets

Onduline offers  roofing solutions to a wide range of buildings including Residential, Commercial Buildings and Resorts, Agricultural, Public Access Buildings, Leisure housing and DIY projects and are used in more then 120 countries around the world.

Onduline is a durable material which can be used for roofing.


Onduline sheets are produced in red, brown and green colors and are easily installed. With Onduline sheets you can create aestetic  roofs.


Weighing  4kg/m², Onduline® sheets are really practical to install: only a hammer is needed for securing the sheets and a band saw for cutting them down to size. Manufactured from recycled fibers, Onduline® sheets contain no asbestos and therefore present no health risk either in installation or when the building is in use.


Manufactured through an environment friendly technology, Onduline® roofing sheet is a flexible and cost effective product that provides weather protection, sound and thermal insulation. It is completely waterproof, cannot rust. It resists most chemicals and corrosion.

Made from most advanced technology, Onduline® sheets have a very low heat conducting coefficients: they provide a perfect seal integrity in all climates and insulate against the noise of heavy rainfall.

Lightweight and flexible, Onduline® sheets are specified by many architects in regions of the world exposed to the risk of hurricanes.

BITULINE- APP/SBS Modified torch-on waterproofing system

BITULINE© is a waterproofing membrane made of modified bitumen reinforced with non-woven polyester mat or glass fiber and resistant to temperatures from 0°C ,-5°C, -10°C,- to -20°C .

BITULINE© is torch apply membrane designed for new roofing and reroofing applications, can be bonded by heat welding over damp or concrete below-grade vertical and horizontal foundation structures and below concrete slabs, on floor surfaces or sloped or flat roofs prepared with BITULINE© primer prior to the application of the waterproofing membrane. 2 mm ,3 mm, 4 mm and 5 mm thick, the BITULINE© membranes are produced in rolls of 10 m x 1 m.

  • BITULINE© base sheets are produced with upper and bottom surfaces with thermofusible PE film and used  for BURs; flat roof terrasses under ballasts gravel, paving slabs, roof gardens or ground level tanking and waterproofing of internal or external underground walls and public works and civil engineering projects.
  • BITULINE© cap sheets are produced bottom surface with PE film and the upper surface protected by granules or aluminium sheet to protect the roof from damaging UV rays. The BITULINE© felts are elastomeric  or plastomeric modified or containing anti-root adjuvants for green roofs.

Onduline offers reliable products for multi-layer waterproofing BUR or tanking solutions.

Onduline is offering  products adapted for BUR of civil works, for waterproofing of industrial floors, rooftop terraces, green roofs and inverted roofs, parking decks,bridges, parapet, zinc roofing projects sealings, gutters, water runs and fireplace hosting, ridge, fascia band edging, box gutters, eaves apron strips flashings, vertical surfaces of rooftop terrasses/planters, culverts, drainage , load-bearing elements and masonry work, foundation slab tanking for new, renovation and repair works.

Reliable and Resistant

Higher tensile and tear strength, shows good dimensional stability, excellent cold-bending behaviour  from 0°C to -20°C.

For effective waterproofing water-tightness alone is not enough. The waterproofing felt must possess a number of additional qualities; adhesion and mechanical resistance in order to resist to the effects of thermal expansion/ retraction, heavy traffic or other loading imposed damaging effects of all likely contaminants, etc. and resistance to the damaging effects of biological, chemical and physical agents.

The waterproofing felt should also resist to aging degradation of the structure in order to maintain the water-tightness of the entire building. BITULINE© membranes have optimal mechanical and physical properties and their quality is ultimate in performance, versatility, and ease-of-use.

Waterproofing range

Depending on the nature of the local, ground, wall, concrete slab or concrete footing and possible water leakage risk,complementary products and accessories  are necessary for the execution of the works.

Characteristics and performances

BITULINE© membranes line have a wide range of characteristics and performances in order to provide turnkey solutions to meet all reliable waterproofing needs.
