Bridge & concrete protection

Seal the deck.
Save the span.

Chlorides, water and freeze-thaw cycles attack bridge decks, parking structures and substructures from the top down. Spray-applied polyurea membranes put a seamless, crack-bridging barrier between that load and the rebar. Learn how the systems work, then let an ArmorThane applicator spec and spray yours.

What we protect

Deck
waterproofing 01

Membranes under asphalt overlays, direct-trafficked wearing courses, expansion-joint tie-ins.

↗ Substructure
protection 02

Pier caps, columns, abutments and splash zones exposed to runoff and deicing salts.

↗ Joints &
crack treatment 03

Detailing over cracks, cold joints and drains so the membrane moves with the slab.

Our approach

Assess

◎

Chain-drag or survey the deck, map delamination, test moisture and chloride exposure.

01

Prepare

▦

Shot-blast to the specified profile, repair spalls, rout and detail cracks and joints.

02

Spray

◈

Prime, then spray the polyurea membrane to thickness with plural-component equipment.

03

Verify

✓

Check film build, adhesion and holidays before the overlay or wearing course goes down.

04
Plan your project

Surface area estimator

A quick area check to include with your quote request. It doesn't give a price; pricing depends on prep, thickness and site conditions.

Questions

Common questions.

Why do bridge decks deteriorate?

Chlorides from deicing salts reach the rebar, it corrodes and expands, and the concrete cracks and spalls.

What does a waterproofing membrane do?

It forms a barrier that limits water and chloride penetration into the deck.

Can a membrane go under asphalt?

Many systems are designed for that. Compatibility and hot-mix temperatures must be checked.

Is surface prep different for bridges?

Typically shot blasting or similar methods to a specified profile, plus moisture checks and repairs.

Do agencies require approved products?

Often. Check the DOT's qualified products list.

How long can lanes be closed?

Fast-set systems help, but traffic control, weather and prep drive the schedule.
