Why Polyurea Is The Ultimate Tool For Primary and Secondary Containment
When used for primary or secondary containment, traditional coatings have been too hard and not sufficiently elastic to accommodate ground, concrete, or metal substrate shift. This deficiency can lead to cracks or holes forming in both the substrate and the coatings, which can compromise containment.
However, the formulation of hard, monolithic, flexible coatings such as
is now resolving this problem for contractors, engineers, and facility administrators. When applied directly to cement or metal surfaces, polyurea not only reinforces and protects the underlying substrate but can also bridge gaps and cracks. polyurea
is now being pre-applied to polyurea liners that can geotextile out in sheets to protect more heavily damaged surfaces or for be instantly rolled field applications such as dirt or rock pads at drilling sites. Once installed, applicators need only coat the seams of the liners to create a monolithic cover use in ideal for containment. that is
Whether at factories, industrial plants, or other manufacturing buildings, federal and state regulations mandate the use of primary and secondary containment systems to keep toxic or hazardous substances from escaping into the earth and potentially entering the water supply.
Implied in this provision is the understanding that primary containment is not infallible. Though durable, metals corrode, concrete cracks, and are porous
, so will drain fluids if uncoated. This requires secondary containment, which often exerts the form of concrete pits with barriers installed around the perimeter of a tank or other storage container. as well
To protect these structures, coatings such as epoxies, tars, and polyurethanes
as an added barrier of protection. However, these traditional coatings are frequently inflexible when cured and can crack along with the concrete. are often employed
Typical coatings do not hold up well to substrate movement or daily, seasonal, or process-related thermal expansion and contraction, which can lead to cracks and leaks.
substrates such as cement or steel, the spray-applied waterproof coating creates a durable, seamless, elastic, protective barrier that prevents leaks and strengthens the integrity of primary and secondary containment systems. The coating exhibits superior physical properties such as hardness, tensile strength, to crack bridging and elongation up to 400%, to create a robust, industrial-grade protective covering. as well as
While traditional coatings such as cementitious, epoxies, tars, and polyurethanes will precipitately fail if not installed under a comparatively narrow range of temperatures,
