(*) This thickness refers to a hydraulic conductivity of a Trisoplast layer with a maximum permeability of 5 * 10-11 m/s, which has been demonstrated by laboratory and field tests to give a level of protection at least equal to the reference construction as described in the Dutch regulations of clay or sand/bentonite with a maximum permeability of 2,3*10-10 m/s and a thickness of 25 cm and 50 cm for capping applications and bottom liners respectively. The thickness already includes 2 additional centimetres for compensating installation inaccuracies.
