STRUCTURAL PROTECTION
Protective Mats made from Recycled Rubber
KRAITEC top, protect and step are elastic products with outstanding resiliency for reliable service under heavy loads. They are made
from high-quality recycled rubber granulate complying with exacting specifications.
and
KRAITEC top and protect are used in buildings and structural systems (flat and green roofs, roof terraces, balconies, tunnel systems,
parking garages, etc.) wherever high-quality insulation or waterproofing requires secure physical protection, i.e. in areas subjected
to physical stressing.
KRAITEC step slabs are an ideal elastic pavement for terraces and balconies as well as access and maintenance walkways on flat
roofs of all types. Their convenient connector pin system makes installation fast and easy. They are available in a wide variety of
colours which can be mixed and matched for eye-pleasing aesthetic design.

6. – on Flat Roofs:
KRAITEC top is the optimum protection mat for flat roofs
supporting foot traffic or heavy objects.
It is often used under gravel-topped roofs to prevent damage
to the waterproofing by sharp or abrasive aggregates or by
subsequent maintenance work.

– on Landscaped Roofs:
KRAITEC top is used as a highly rugged and durable separator
layer on landscaped roofs supporting foot traffic and auxiliary
structures (e.g. over parking garages or green roofs). It protects
the waterproofing system below against damage due to
compressive loading.

7. – on Roof Terraces:
KRAITEC top plays an important part in construction of above-roof
systems such as roof terraces. Installed directly below the terrace
surfacing (e.g. concrete slabs or wood planking), it protects the
waterproofing and roof below against puncture and other damage
under high loads. In addition it serves as an equalizing and sound
insulating layer.

– in Parking Garages:
KRAITEC top enhances design safety when used as a
component in waterproofed surfaces in urban parking facilities.
Installed under the pavement, the protective mats increase
the permissible load rating for vehicle traffic and improve the
overall safety of the structural system.

10. KRAITEC protect is the heavy-duty protective sheet for
extreme applications and structural loads. It is a premium
product made from selected materials complying with strict
specifications. Due to its high volume weight, KRAITEC
protect does not require weighing down prior to installation
as do geotextiles. Made to exacting quality standards,
KRAITEC protect is extremely rugged and is the optimum
solution wherever highest physical demands must be met.

KRAITEC protect has outstanding physical properties
which make it ideal for use over waterproofing subjected
to extreme compressive loads or dumping of gravel or soil.
It has excellent puncture resistance and can take rough
treatment of all kinds without damage. KRAITEC protect
provides outstanding protection over waterproofed surfaces
in tunnels whether horizontal or vertical.

14. – Walkway Slabs:
Flat roofs are often subjected to foot traffic, e.g. for
maintenance or other work procedures. Installed directly
over the waterproofing, KRAITEC step and step plus
walkways ideally protect the roof against physical damage.
