Tough, Tougher, TECTAVO.

With TECTAVO every bitumen roofing membrane can withstand hot temperatures or strong impacts. Thanks to its high degree of crystallinity it significantly improves the resistance to permanent deformation such as walking on the
roof at high temperatures.


Stands the Test of Time.

TECTAVO has a real anti-aging effect on roofs. The addition of Fischer-Tropsch wax increases the tensile strength of the
bitumen membrane. The result is a strong protection against damages for long-lasting durability. 50% of bitumen ageing occurs while the roofing membrane is being produced. Warm mix technologies can reduce short-term ageing significantly while considerably extending the service life of bitumen membrane.

The Perfect Recipe
for Cost-Efficiency.

With TECTAVO you can optimize the recipe for your bitumen roofing membranes even further. By adding our innovative Fischer-Tropsch wax, you can replace expensive components to meet all the required parameters for the best possible performance and cost-effectiveness.


A Good Balance
Between Work and Nature.

TECTAVO offers the possibility to compose a harmless alternative to oxidized bitumen. Due to lower temperatures workers are exposed to less fumes. The Fischer-Tropsch wax itself is classified non-hazardous.


Tested, Approved
and Highly Recommended.

With the usage of TECTAVO and the right adjustment of the recipe all quality standards for bitumen roofing membranes can be met: Directive 2001/95/EC on General Product Safety, REACH-Regulation (EC) No 1907/2006 and CLP-Regulation (EC) No 1272/2008.
