Corrosion Barrier
The vinyl shell is the permanent corrosion barrier and finished face — the reinforcing steel inside never touches salt water.
A vinyl form on the outside, steel-reinforced concrete poured inside — concrete strength behind a corrosion barrier.
Reinforced concrete that never touches salt water
Truline panels are interlocking vinyl forms. We drive them like sheet pile, set the reinforcing steel inside, and pour concrete into the form.
The result is a reinforced concrete wall whose steel never touches salt water — the vinyl shell is the permanent corrosion barrier and the finished face. Two practical advantages matter on real properties. First, Truline can often be installed directly in front of an existing failing wall, turning the old wall into backstay and skipping demolition. Second, the forms cut and curve far more easily than large precast panels, which matters on lots with returns, radii, or pipe penetrations.

A poured, steel-reinforced concrete core gives Truline section strength comparable to conventional reinforced concrete.

A 50+ year vinyl shell paired with a concrete core whose steel is sealed away from salt water — each material covers the other’s weakness.

More than vinyl sheet alone, often competitive with full concrete replacement once demolition savings are counted.
Truline sits between our vinyl and concrete systems: more section strength than vinyl sheet alone, with corrosion protection conventional concrete can't match. It's a strong fit for failing-wall replacements where demolition is costly, and for owners who want concrete structure with a clean, uniform face. Not sure which system your property needs?
