ArmorThane touts spray polyurea for shipping container pools

ArmorThane USA Inc. is positioning spray-applied polyurea as a waterproofing option for shipping container pools, arguing the elastomeric membrane can flex with a structure that was not built to hold water. The company says the approach matters for builders because container conversions face hydrostatic pressure, movement and penetration detailing challenges.

Why it matters: - Shipping container pools put unusual stress on a structure that was not originally designed to hold water. - A waterproofing layer for these conversions has to stay continuous while the container moves during lifting, transport and installation. - Builders and applicators need a system that addresses both waterproofing and finish requirements without creating weak points.

What happened: - ArmorThane USA Inc. is promoting spray-applied polyurea waterproofing for applicators converting shipping containers into swimming pools. - The company says the application suits a structure that moves and needs a lining that can move with it. - ArmorThane says container pool work fits within its broader water feature applications.

The details: - Spray-applied polyurea is an elastomer applied in place and bonded directly to prepared steel. - The coating forms one continuous membrane across walls, corners and floor without overlapping joints. - Skimmers, returns and light housings are detailed into the membrane during application rather than sealed as separate components. - The company says container pool walls face hydrostatic pressure and welded window and fitting penetrations can concentrate stress. - ArmorThane says the polyurea membrane serves as the primary waterproofing layer, while the finish addresses appearance and exposure requirements. - Aromatic polyurea is normally specified with a topcoat where appearance and ultraviolet exposure matter. - ArmorThane is evaluating topcoat options for the combination of chlorinated immersion and direct UV exposure in a container pool. - The company recommends confirming coating selection for continuous chlorinated-water immersion for the specific service conditions. - ArmorThane says success depends on coating selection, structural behavior, substrate preparation and detailing every penetration. - The company says container floors may arrive with unknown wear from prior service, making surface preparation critical for adhesion. - ArmorThane says the waterline transition and the detailing at skimmers, returns and light housings need close specification attention.

Between the lines: - The pitch is less about a single coating product and more about a system that accounts for movement, adhesion and penetration details. - The emphasis on separating waterproofing from finish suggests ArmorThane is trying to keep the technical job of sealing water distinct from the aesthetic job of surface appearance. - The mention of evaluation for chlorinated immersion and direct UV exposure signals that the final coating stack may depend on the exact pool environment.

What's next: - Builders, applicators and specifiers evaluating a container conversion can contact ArmorThane for coating application information and technical requirements. - ArmorThane says coating selection should be matched to the specific service conditions before a project moves forward. - The company will continue to position container pools alongside concrete pools, koi ponds and water gardens in its water feature portfolio.

The bottom line: - ArmorThane is betting that spray-applied polyurea can solve one of the hardest parts of container pool conversions: keeping a rigid steel shell waterproof while it still flexes.
