T-Lock Membrane

Hdpe and Pvc Based Membrane

The unique feature that differentiate T-LOCK geomembrane is the continous T shape tabs on the surface. With these tabs, T-LOCK Geomembrane does not move in the concrete and prevents damages against concrete by blocking vibrations. Thus, the constructions shall be healtihier and more long-lived.

It contains general HDPE and PVC Geomembrane properties. Especially its resistance to chemicals and aging life is increased.

Especially its resistance to chemicals and aging life is increased.

  • High resistance to chemical substances.
  • They are UV resistant.
  • Very high tensile strength.
  • Low permeability.
  • It is extremely resistant to puncture and cracking.
  • Provides superior protection against infiltration.
  • Resistant to natural conditions.
  • It shows high resistance to organic and inorganic solvents.
  • It can be easily applied to all kinds of floors.
  • It can be made with Geotextile reinforcement upon request.
  • It is recyclable and reusable.


It is combined with fusion welding (double-stitched test space welding) system, it is laid by free laying technique with 6-10 cm overlap. It is fixed with printing profiles at the end points according to the requirements of the application.

Usage areas

  • Concrete pipes
  • Irrigation channels
  • Collector chimneys
  • Roofs
  • Building foundations
  • Tunnels
  • Collector chimneys
  • Dams
  • Landfills


The materials are dispatched in the form of roils with 6m – 9,5m width and 100m – 200m length.

The materials must be stored on smooth surface. The stored products must be kept away from direct sunlight, heat and combustible sources. In case the rolls must be stored outdoors for long duration, then the rolls must be covered for protection against sunlight. Absolutely no smoking in the storage yard.
