Great Northern Tank liners are fabricated exclusively from ARMASeal a new generation tank liner material.
ARMASeal is a 4-layer tank liner fabric comprising of a “double deck” polyethylene tape woven scrim reinforcement, a polyethylene coating layer on both sides of the scrim reinforcement and a polyethylene film layer on the top (water side).
The material construction differs from traditional tank lining materials on the market in that the scrim reinforcement, which gives a tank liner material its strength, has innovative “double deck” arrangement.
This innovative polyethylene tape woven “double deck” arrangement provides the material with the strength it requires in a tank liner application and simultaneously provides a level of flexibility which is also important in a tank lining material.
By using polyethylene tape as the reinforcement, this also allows the material to have better elongation or stretch properties than other scrim reinforced tank lining materials.
This allows ARMASeal to conform to most deformations in the underlying substrate without rupturing and developing a leak, much better than polyester and polypropylene spun yarn reinforced tank liner fabrics.
With both the scrim reinforcement and coating layers being 100% polyethylene, a high-strength homogeneous bond is ensured. Certainty of water-tightness is achieved by an additional bonded layer of polyethylene film.
During fabrication of the tank liner, the tank liner’s seams are tape-welded to provide a further barrier against water ingress.
Following fabrication, each ARMASeal tank liner is put through a rigorous inspection and testing regime to ensure compliance with the highest quality control standards.
ARMASeal tank liner material is fully certified by the Australian Water Quality Centre to comply with the most stringent requirements for potable water; AS/NZS4020 – Products for use in contact with drinking water.
Due to all elements of the ARMASeal material make up being 100% polyethylene based, at the end of a long service life ARMASeal tank liners are 100% recyclable.
