*Not included in the system structure diagram. **Depends on temperature and inclination (15–20 %).
For high inclinations of 15–20 %, the use of Sika® Extender T in the wearing layer may be used.
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
