Two-colour PVC signal geomembrane installed over a concrete structure

Hydroblock

HYDROBLOCK® PVC geomembrane — signal layer

Two-layer PVC sheet with a contrasting underside. Damage flakes the top colour away and reads dark, so punctures are found by eye.

A dual-layer, two-colour PVC geomembrane for concrete structures. The lower layer is a deliberately contrasting colour; where the sheet is struck or torn, the top layer flakes and the dark layer shows through.

That matters on site because the expensive failures are the ones nobody sees. A signal sheet turns membrane inspection into a walk-over rather than a spark test.
