A large range of products provides a suitable answer to all kind of applications whatever the constraints are. Coletanche products can be laid on harsh subgrades with up to 25mm aggregate and in difficult climatic conditions.

The ES range is manufactured with highly elastic elastomeric bitumen which is very resistant to ultra violet rays even in exposed conditions.

The products are available in 4 different thicknesses (from 3.5 to 5.6 mm) to provide an efficient answer to whatever mechanical constraint the product will be submitted to.

For applications on steep slopes which, our special High Friction Angle (HFA) grades can be made. These grades replace the root barrier film with a peel away siliconized paper which reveals a tacky bitumen to contact the subgrade. Contact our technical team to see if the HFA material is right for your project.

*Out-of-standard lengths and widths can be manufactured on request.
