Hydroblock
HYDROBLOCK® PVC geomembrane — signal layer

HDPE geomembrane — textured & signal (HD-ST)
Black homogeneous HDPE, flat or textured, optionally with a light signal layer so damage reads as a contrast.
Single-colour, homogeneous HDPE sheet supplied flat or textured — textured where the liner runs on a slope and friction against the subgrade is doing structural work.
The HD-ST variant carries a thin, light-coloured layer on one face. Any scuff or puncture shows immediately against the black beneath it, which shortens the CQA walk considerably.
