Coating materials fail primarily due to environmental conditions during and after application. They are by nature, permeable - not because of chemical composition, but due to the method of liquid application over the porous concrete substrate. Nothing can match an extruded plastic Co-Liner™ for H2S protection, because the extruded liner is not reliant upon, or subject to, the gas permeability which is inherent in the method of application of all coating materials. Over a 30 year period of developing seam materials for PVC liners, Linabond® has had extensive experience dealing with the severe environmental conditons of wastewater structures. This testing and experience has led to the Linabond® Linathane Permanil™ coating materials. They have an extraordinarily long life cycle for coating materials because they wet extremely well and cure quickly enough to minimize the permeability and porosity that has continuously plagued coating materials. Permanil™ coatings are not extruded liners, and nothing will match the performance of the semi-rigid Linabond® PVC Co-Liner™. But the Permanil™coatings are vastly superior to any other coatings we have tested, when compared to the unattainable level of protection provided only by an extruded Co-Liner™ which cannot be matched by any liquid-applied material or extruded liner alone.
