Professional Pedestrian Deck Waterproofing
Serving Denver and the Front Range with high-performance membranes, traffic coatings, and restoration systems designed for durability.
System Selection
Plywood and Concrete Require Different Assemblies
A successful deck-waterproofing system must be compatible with the substrate, structure, drainage design, environmental exposure and finished surface.
Plywood Walking-Deck Systems
Reinforced, polymer-modified waterproofing systems may be used over qualifying exterior-grade plywood when the framing, fastening, slope, moisture condition and perimeter details meet system requirements.
Concrete Walking-Deck Systems
Reinforced waterproofing systems may be installed over qualifying elevated concrete after cracks, moisture, previous coatings, surface profile, joints and drainage conditions are evaluated.
Under-Tile Assemblies
Exterior tile or stone requires a complete assembly that coordinates waterproofing, drainage, movement accommodation, setting materials, transitions and the selected finish.
Restoration and Recoating
Existing systems may be repairable or suitable for recoating only when their bond, compatibility and underlying substrate condition are acceptable.
Westcoat System Options
Project-specific options may include Westcoat ALX Pro for qualifying plywood walking decks, MACoat for qualifying elevated concrete or reinforced-plywood walking decks, and compatible under-tile configurations. Final system selection is made after reviewing the actual project and current manufacturer requirements.
What We Evaluate
Waterproofing Begins With the Details
- Substrate type and condition
- Door thresholds
- Structural movement or visible deterioration
- Rail posts and penetrations
- Plywood thickness, fastening and moisture
- Cracks and movement joints
- Concrete moisture and existing coatings
- Exterior exposure and temperature
- Slope and water drainage
- Occupied or finished areas below
- Drains, scuppers and deck edges
- Desired texture and appearance
- Wall-to-deck transitions
- Required cure and access schedule
Damaged framing, structural movement, inadequate slope, drainage problems and incompatible materials may need to be corrected by the appropriate project trade before the waterproofing system is installed.

Our Process
A Coordinated Approach to Deck Waterproofing
01
Project Review
We review photographs, plans, approximate dimensions, intended use, exposure and whether occupied space is located below the deck.
04
Preparation and Repairs
Qualifying surfaces are prepared and approved repairs are completed according to the selected assembly. Structural or trade-specific corrections are identified separately.
02
Site Evaluation
We inspect accessible substrate conditions, drainage, slope, transitions, penetrations, existing materials and areas requiring further investigation.
05
Reinforced Waterproofing Installation
The approved reinforced layers, waterproofing materials, texture and finish coats are installed in the required sequence.
03
System and Detail Planning
We coordinate the proposed system with current manufacturer requirements for the substrate, drains, flashing, edges, walls, thresholds and other transitions.
06
Inspection and Care Plan
The completed surface is reviewed and the owner receives applicable cure, cleaning, inspection and maintenance information.
Inspection and Maintenance Matter
Waterproof deck systems require periodic inspection. Sealants, drains, transitions, finish coats and areas showing wear should be reviewed according to the manufacturer’s maintenance requirements and the deck’s traffic and exposure.
- Keep drains and scuppers clear
- Avoid puncturing the waterproofing assembly
- Report cracks, damaged sealants or unusual movement
- Follow approved cleaning instructions
- Schedule periodic condition inspections
- Recoat or repair worn areas when recommended
Can the same system be installed over plywood and concrete?
No. Plywood and concrete have different movement, preparation and assembly requirements. The system must be selected for the actual substrate.
Can an existing deck be waterproofed?
Possibly. The existing surface, bond, substrate, slope, drainage and damaged areas must be evaluated before repair or recoating is recommended.
Can tile or stone be installed over the waterproofing?
Certain under-tile systems are designed for this application. The complete waterproofing, drainage, movement and tile-installation assembly must be coordinated before work begins.
Will the finished deck be slip-proof?
No surface is slip-proof. Available textures may improve traction, but appropriate texture, cleaning, drainage and maintenance remain important.
Does waterproofing repair structural damage?
No. Deteriorated framing, structural movement, unsafe conditions or major concrete damage must be evaluated and corrected by the appropriate qualified professional.
How often does the deck need maintenance?
Inspection and recoating schedules depend on the system, traffic, UV exposure, weather, drainage and surface condition. Project-specific care information is provided after system selection.
