KRAITEC® step
Innovative, versatile and a variety of design options
The coloured polyurethane binding agents used to bond the granulated tyre granulates in KRAITEC® step provide a variety of colours which can be mixed and matched in eye-pleasing combinations. But also with a single coloured KRAITEC® step surface you will always have a decorative, modern and warm surface for terraces and balconies, easily to be installed with integrated connector pins. Drainage channels on the bottom side ensure secure removal of water. The slabs are easily installed on any paved level subsurface.
KRAITEC® step can be conveniently installed directly over bituminous membranes
Application Examples
For terraces and balconies
KRAITEC® step products are high-quality elastic surfacing slabs made from recycled rubber. They are comfortable to walk on, look great and provide outstanding surfacing on terraces and balconies as well as on walkways around houses and in gardens.
On flat roofs
Flat roofs must allow access for maintenance, repair and cleaning work. KRAITEC® step is ideally suited for walkways and as protective mat for waterproofing systems on flat roofs.
KRAITEC® step can be directly installed on all types of waterproofing thus protecting the roof system from damage. Material compatibility must be clarified beforehand. For problematic material combinations we recommend KRAITEC® step plus with polyester geotextile laminate (300 g/m²) on the bottom side.
Installation of KRAITEC® step is fast and simple using the connector pins supplied. The surface can be walked on immediately after installation. This dense and rugged rubber slab is also well suited for use in support pads under roof-mounted structures (antennas, air conditioning units, etc.)
Support Pads:
These dense and sturdy slabs provide an ideal solution for support pads under heavy structures located on small areas on roofs such als solar power units, air conditioning units, satellite antenna dishes etc.
Terrace Pavements:
Installation of KRAITEC® step is done by hand without need for tools, covering large areas quickly and easily. The connector pin system and installation in a masonry-style configuration ensure stable and secure placement.
KRAITEC® step provides an optimum terrace pavement over level paved surfaces. The available palette of colours permits personalized design and diverse solutions providing attractive, eye-pleasing surfaces.
Balcony Pavements:
When installed on small areas such as balconies, KRAITEC® step can be installed in a cross-joint configuration if desired. Here as well, the selection of colours permits eye-pleasing design combinations.
Along with the cushioning effect inherent to elastic surfaces, KRAITEC® step offers additional benefits: it can be installed quickly even in tight spaces, is easy to trim to required sizes and can be walked on immediately after installation.
Impact Sound Insulation
KRAITEC® step tested roof system: Insulation = PIR, waterproofing = bitumen
Example for impact sound reduction: ΔL w = 27 dB
KRAITEC ® step satisfies the criterion „hard roofing“:
Materials used as top layers on flat roofs must resist flying sparks and radiated heat to minimize fire risks.
KRAITEC® step was tested by an independant testing institute and received the classification Broof (t1) according to DIN EN 13501-5 (testing based on DIN V ENV 1187). The „hard roofing“ criterion is proved by a general building authority test certificate (test number: P-3692/139/11-MPA BS). KRAITEC® step - contributes considerably to the protection of your valuable property.
