System Bituline covers the modified bituminous and their accessories together with their application methods.
Bituline membranes are used for the waterproofing of flat and low pitched roofs, terraces, wet surface flooring of underground surfaces such as foundations, basement and pools or of particular engineering such as multistory parkings or motorway bridges.
Advantages:
* Bituline membranes, the fundamental element of waterproofing, are manufactured of high quality bitumen modified with polymers and reinforced with polyester or fiberglass of different thicknesses and whenever required with various coatings on the surface and therefore have a broad product range enabling the selection of the most ideal material that fits best to a particular application need.
* Thanks to the modified bitumen, insulation retains its flexibility even under very low temperatures, free of any cracks, while loosening rather late and thus maintaining its form under high temperatures. This is why Bituline system may be used safely under any climatic conditions.
* The fact that the Bituline membranes are manufactured using a state-of-the art technology equipment at a factory environment, ensures homogeneous waterproofing as well as integrity of materials in terms of quality, which eliminates any insulation risks due to difference in performance, as common with the traditional systems implemented through application by laying of product mixes prepared in site.
* The membranes are combined together by fusion welding and then simply bonded onto the desired surface. This welding technique makes waterproofing permanent. The waterproofing of the Bituline system is also complete at joints.
* The reinforcement set into the membranes increases the tensile strength and pressure resistance of the waterproofing. System Bituline is thus available for use safely at such locations where levels of exposure to mechanical stresses are considered high, such as motorways ,bridges, road pavements, etc
* Available with granulated mineral or aluminum coated with a wide range of colors at request, Bituline membrane is especially ideal for use as a final coat waterproofing material, as they are not affected from airborne particles of chemical and biological nature and are resistant to UV beams, while providing aeshetically attractive surfaces all times.

 

 

Bituline Prima
Prima series membranes
The “prima” series consist of plastomeric membranes modified with “Atactic Polpyropylene”(APP).Bituline Prima membranes are in compliance with the cold and warm weather conditions of mild climate zones, offering economic and reliable waterproofing system with a wide spectrum for different types of buildings.

 

 

Bituline Extra
Extra series membranes
The” extra” series consist of plastomeric membranes modified with “Atactic Polypyropyleon”(APP).Extra series membranes having increased their tensile strength with stronger polyester reinforcement perform better at high and low temperatures regions with extreme climatic conditions with its flexibility and durability. EP410 is an especially formulated “heavy load” membrane for use in the waterproofing of highways.

 

 

Bituline Maxima
Maxima series membranes
The :maxima” group contains elastomeric membranes modified with “Styrene Butadiene Styrene”(SBS).Having the highest possible flexibility even at lowest temperatures, Bituline Maxima membranes are especially suitable for cold climates, and are also ideal for “bundle” type foundation waterproofing against underground water subject to pressure as well as for roof subject to high vibrations or dilatation.

 

 

 

Bituline Aluminium
Aluminum foil coated membranes are used as the final layer material like granulated types. Their technical specifications are identical to Extra Group. (see: Technical specifications sheet) On request Bituline Aluminum can be supplied also as an elastomeric membrane.

 

 

 

Bituline Perfor
Bituline Perfor, loose laid on the substrate, provides the partial attachment of the first Bituline layer to be torched on. This application system allows the perfect distribution of vapour coming out of the building, avoiding any possible problems of bubbling and blistering.

 

 

 

Application Guidelines
The rolls should be handled and stored in vertically upward position. If the use of materials in cold weather is desired, they should be stored at standard room temperature for 24 hours before application, in order to render workmanship easy and sound. No applications should be made under cold weather conditions where the temperature tends to fall below +5ºC.

The application of Bituline in two layers, the sublayer being reinforced with fiberglass and the second layer with polyester is considered to be a good practice, when waterproofing is to be made on flat roofs with inclinations up to 5%. The selection of the type and thickness of the membrane to be applied will depend on the characteristics of the type or mode of utilization of the building and to the climatic conditions prevailing in the area. Excessive care should be taken to ensure that application surface on which the membrane is to adhere is clean and dry at time of application, and a single layer of undercoat Bituline primer should be applied to the surface to ensure a good retention. In full adhesion technique, all the surfaces along which the upper membrane layer contacts with the ground or with the sublayer membrane are treated with fusion welding technique using a welding torch.
 

 

When Bituline Perfor is used, the membrane shall facilitate an ideal vapor distribution as it will adhere onto the ground on a pointwise basis. However, Bituline Perfor should be laid avoiding any material overlaps and should never be adhered to the application surface at a prior time. The fusion weld should be applied to the first membrane layer coming over and appropriate measures should be taken to ensure that the bitumen melt due to fusion adheres to the surface perfectly after passing through the holes of Bituline Perfor.
Bituline rolls should be aligned so that they overlap one another by 10cm both at length and width. Wile overlapping mineral coated membranes at length, the granules must be scrapped off completely, followed by their heating using the welding torch and embedding them into the membrane, to produce an overlapping length of 15cm.

 

 

Rows of membrane should be formed perpendicular to the direction of slope in all layers, while care is taken to avoid intersection or overlapping of joints to the extent possible, employing the deviation technique.

 

 

At terrace type open roofs insulated with the conventional system, the heat insulation layer is placed under the waterproofing layer, wher there is a wide variety of options to use for this purpose, including glass wool or rock wool with a minimum density of 150kg per cubic meter and extruded or expanded polystyrene foams( XPS or ESP) with a minimum density of 30kg per cubic meter.

In inverted roofing system, there is no need for using of a vapor barrier, as the heat insulation layer stands above the waterproofing. On the other hand, heat insulation should be absolutely provided by employing a waterproof material(i.e.XPS), and considerations should be given to the fact that a certain amount of heat loss would occur due to the passage of rain waters discharged underneath the heat insulation layer.

For waterproofing of light metallic roof system commonly used on reinforced concrete, heavy prefabricated or steel system, the sublayer membrane is fixed onto the roof panel applying mechanical means. A membrane layer coated with granulated mineral is employed as the second layer. Here, as a widely flexible, moving roof system is in concern, it is essential that membranes with high elastomeric characteristics should be preferred.

It is normally essential for waterproofing made against pressurized ground waters that the target structure should have a mat foundation system where the insulating layer passes beneath the foundation and extends up to a maximum 20cm above the ground level as a single piece layer on screening walls. It is also very important that the waterproofing should be protected against piercing once it is completed.
