KRAITEC® top - on Flat Roofs
KRAITEC® top is the optimum protection mat for flat roofs upporting 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.

KRAITEC® top - 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.
KRAITEC® top - 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.

KRAITEC® top - 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.
