Black and White Liner

Agru’s Black and White geomembranes offer the advantages of both a light reflective white surface and a black damage detection layer.

The liner’s UV resistant white surface reflects light – minimizing associated heat absorption by as much as 50% – and thus reducing the potential for membrane wrinkling due to thermal expansion and contraction. Traditional black HDPE geomembranes can reach temperatures of 160°F or more and experience thermal expansion exceeding 1% depending on temperature swings.

Visual inspection of the liner for damage is greatly improved. Damage is indicated by any scarring beyond the white, light reflective layer as the contrasting black primary layer is clearly exposed.

Agru’s Black and White Liner is available in high density polyethylene (HDPE) and linear low density polyethylene (LLDPE), MicroSpike® texturing and smooth surface.

Benefits of Black and White Liner

  • Minimizes heat absorption – and resulting thermal expansion – by up to 50%
  • Significantly improves damaged detection via white signal layer
  • Available in HDPE, LLDPE, MicroSpike texturing and smooth surface
