KRAITEC® top


Structural protection - versatile and effective

KRAITEC® top is the versatile and effective protection mat for classical applications on flat roofs and building structures. Leading waterproofing manufacturers and installers worldwide work with this field-proven product. Its outstanding technical properties, high compressive strength and remarkable application versatility make KRAITEC® top the preferred protection mat for all classical flat roof systems.



KRAITEC® top is easy to install, highly cost-effective, durable, and extremely rugged and can be walked on immediately after installation. Whether used as temporary protection for work over easily damaged membranes or as a permanent component in flat roof systems, this classic product is at home over waterproofing systems worldwide.


Due to these and other benefits KRAITEC® top is the largest-selling structural protection mat of KRAIBURG RELASTEC.


 


Application Examples

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 susequent 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 areas or green roofs). It protects the waterproofing system installed below against damage due to compressive loading.



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 applications without full-surface covering (e.g. installations under spaced-slat flooring or other noncontinuous surfacing), we recommend our odourless Kraitec® protect.




In parking garages:

KRAITEC® top enhances design safety when used as a component in waterproofed surfaces in urban parking facilities. Its outstanding properties increase the overall safety of the structural system.
