More about polymer-bitumen membranes

The most widespread materials for the creation of the waterproofing layer are the polymer-bitumen roll-fed membranes. This is due to the relative simplicity of installation, popularity of the technology, durability of the material and stability of the factory-set technical parameters. Polymer-bitumen membranes are commonly used for waterproofing of foundations, engineering structures, roads, bridge decks and flat roofs. These materials could also be used as an underlay for pitched roofs and as a vapor barrier.

The waterproofing membrane not only protects the internal premises from water penetrating inside, reducing their operating ability, disturbing the process equipment operation and worsening the microclimatic conditions indoors, but it also prevents the destruction of the foundation and supporting structures. Therefore, the correct selection and installation of the waterproofing membrane also ensure the durability of the whole facility.

Polymer-bitumen membranes undergo effects of many unfavourable factors from the external environment. Changes in the surrounding temperature can cause deformations of the material and the base on which it is installed. The ability to withstand such deformations is the most important characteristic of roofing and waterproofing material and it depends on many components used on the production stage.


The compound is a specially formulated mixture of bitumen and polymers. The main difference between compound types is the kind of polymer used:




The special adhesive polymer-bitumen compound is used for the production of self-adhesive membranes. The compound is covered with easily removable protective film. Self-adhesive materials grant high speed of safe and cheap application and do not require any additional equipment and skills. Such materials can also be used in conditions, when the standard torch-on application is forbidden (expanded / extruded polystyrene or wooden base, indoor waterproofing).


Fine-grained sand or talcum can be used to cover the top or underside surface of the membrane. Such type of covering allows installation by hot or cold applied mastics or by torching.


The coarse-grained mineral slate with special hydrophobic treatments protects the material from damage by ultraviolet radiation during the whole service life of the membrane. It is used for cap sheet membranes in double-layer waterproofing systems.

Slate can be supplied in various colors that will provide nice aesthetic appearance. Standard colors include natural grey, red, green and white, while other colors are available on request.
