Westcoat waterproofing systems
Compare practical Westcoat starting systems for plywood and concrete balconies, roof decks and walkways, then match the assembly to drainage, movement, transitions and the occupied space below.
Westcoat walk-deck waterproofing
America Roofing can install Westcoat waterproof deck systems across the broader manufacturer line. These four systems are the most useful starting points for Arizona walk decks because they cover common plywood, concrete, elevated balcony and multi-family conditions.
Plywood decks
A reinforced waterproof walking-deck system for plywood balconies, roof decks and walkways, with standard, custom and solar-reflective finish directions.
Reinforced plywood assemblies
A higher-build ALX configuration that adds a fiberlath-reinforced membrane for compatible plywood deck assemblies and demanding exterior conditions.
Concrete and compatible plywood
A fiberlath-reinforced waterproof deck system used on balconies, corridors, stairs, plazas and landings, with flexible finish and texture choices.
Plywood and selected concrete conditions
A value-engineered, fabric-reinforced waterproof deck system developed for multi-family properties and repeat balcony or walkway conditions.
System selection
Arizona heat and sun matter, but the substrate controls the first decision. Plywood and concrete move, absorb moisture and accept reinforcement differently. A system that works on one deck should not be substituted onto another without checking the manufacturer’s published assembly and the conditions in the field.
Walk decks also concentrate risk at door thresholds, wall transitions, railings, scuppers, drains and perimeter edges. America Roofing evaluates those details with the deck surface so the proposal can name the system, repair boundary, finish and maintenance expectations clearly.
The existing substrate, fire-rating requirements, drainage, movement, occupied space below and desired finish determine the final assembly. The written scope should identify the exact Westcoat system and finish—not simply “deck coating.”
Westcoat walk-deck questions
The brand is only the starting point. Substrate, drainage, transitions and the written assembly determine whether the waterproofing plan fits the property.
ALX, ALX Pro and Shur Deck include configurations intended for compatible plywood deck assemblies. The correct choice depends on substrate condition, fire-rating requirements, drainage, movement, finish and the space below.
MACoat is a common starting point for elevated concrete balconies, corridors, stairs, plazas and landings. Shur Deck also has project-specific concrete configurations. The existing surface still needs adhesion, moisture and movement evaluation.
Yes. America Roofing can work across the broader Westcoat waterproof deck line. ALX, ALX Pro, MACoat and Shur Deck are highlighted because they cover the most common substrate and building conditions encountered in walk-deck planning.
No. The scope should also identify demolition, substrate repairs, slope and drainage corrections, reinforcement, walls, doors, railings, edges, finish, curing limits and maintenance requirements.
