Traffic coating applies to both parking decks and pedestrian decks – both require high performance coatings applied by an expert.


Maintain the structural integrity  and increase the appeal of your structure.

Each Parking garage is an integration of components functioning together as one. All systems must be in good repair in order to maximize the life of the structure. Restoration and waterproofing are key elements to extending the life of parking decks and parking garages.

Essentially porous, concrete parking decks absorb water, which migrates through the top of the slab through the bottom. leaving chloride deposits underneath, commonly called “efflourescence”. Long term exposure to moisture can eventually cause the reinforcing steel in the slab to corrode, causing the concrete to spall.

To prevent moisture from migrating through the slab, the top surface is shotblasted the achieve profile and remove contaminants, and then coated with typically a three coat urethane coating system.

Elastomeric coatings systems are sustainable; designed to be maintained over the life of the structure and not removed and replaced. Neogard’s Autogard II elastomeric coating system has been known to last over 30 years with minimal maintenance.

Urban Waterproofing is Certified to apply Neogard, Pacific Polymers, 3M,
Sonneborne, Tufflex, Carlisle, and other high quality elastomeric deck coating systems.


Pedestrian traffic coating systems are typically installed on ramps, walkways, and both large and small decks within complexes.

Unlike vehicular coating sytems, pedestrian deck coating systems are often applied over wood, and require special detailing at the plywood seams and other penetrations.

In some cases, the elastomeric coating system with a sand mixture is used to create slope in the deck to move water that is ponding in a certain area, or direct water towards a drain.

Pedestrian coating systems are also available in a wide variety of standard colors to give owners and occupants more choices for matching the coating with the existing colors of theri structure.

Ensuring a quality job every time.


Traffic coatings are designed to last for man years while under constant use, either from car tires or pedestrians.  It is important at the beginning of the project to make sure the new system will adhere properly to the substrate it is applied to, and adhesion tests are the best way to be sure.  In addition, it is best for the team to review and approve aesthetics prior to mass-application.
Most traffic coatings are not designed to withstand prolonged ponding.  It is best practice is to move the water to drains as soon as possible for both aesthetic and safety considerations, and to ensure longevity of the coating.  If the structural deck is not adequately sloped, leveling mortar/epoxy can be used to create slope.
Applying the right amount of material is important when working with high-performance coatings.  Mill thickness gauges are placed into wet coating, as well as the grid method, where pails of material are strategically placed on the deck surface to show mechanics at which point they should be ready for a new pail of material.
Moisture vapor makes its way through the concrete slabs, especially where those slabs sit directly on grade. Different coatings have different tolerances to this moisture, so it is critical to know how much vapor drive there is before selecting a traffic coating.
Decks, both concrete and wood, need to be sound before applying any coating on top of them.  Spalls in concrete, or delaminated leveling compound in concrete decks, or dry-rotted plywood in wood decks all need to be repaired before installing a new traffic coating system on top of the deck surface.
High performance traffic coating systems sometimes have a strong odor.  While there are odor masking additives, it is best to use fans or make adjustments to intake and exhaust systems when possible to move the odor as quickly as possible.
Parking decks are a significant revenue source for their owners.  While downtime  for the installation of a traffic coating is system is necessary, it is important to be strategic in how the work is phased to keep as much of the parking deck operational at a time.  Pedestrian decks also require careful phasing consideration to maintain access as much as possible.
Successful application of traffic coatings is a team effort, and requires experience in all roles – from the technician who mixes the material at the mixing station, to the crew who pours out the material evenly, to the person who spreads out the material, and finally to the back-roll crew.
Traffic coatings require the addition of aggregate in the topcoat to provide traction.  Without aggregate, the finished coating can be extremely slick, and a safety hazard.  Aggregate, either sand, small rubber pieces, or even walnut shells are applied evenly from a pail.  Even distribution is critical, to prevent ”shiners” (areas where there is no traction) and for aesthetic reasons.
“You have a great team. They were always very considerate of our elderly residents and they were all very focused on safety. Urban does high quality work. Everyone at Smith Ranch Homes shares that same opinion. That opinion never wavered or changed.”
