Case Study: Commercial Waterproofing That Protected & Met Deadlines

When it comes to commercial buildings, waterproofing is vitally important. Without it, water infiltration can lead to significant damage with costly repairs and delays. The right fluid-applied waterproofing system can save your building from foundation damage, mold, mildew, excessive humidity, prevent health hazards, reduce energy costs and speed up your construction timeline.

If deadlines and budget restrictions have you stressed, keep reading to learn how EPRO provided solutions for the Ritz Carlton project in Paradise Valley, Arizona.

The Project

Located in aptly-named Paradise Valley, Arizona, the Ritz Carlton hotel and residences were set to combine a luxurious hotel with high-end living. The project encompassed a 200-room Ritz Carlton resort surrounded by 91 single-level villas and 45 single-family homes. 

The hotel was to become home to the longest pool in North America, spanning more than 400 feet with a 30,000 square foot spa featuring indoor and outdoor treatment areas. 

Guests would be spoiled with a state-of-the-art health and fitness center, both indoor and outdoor meeting event spaces, a citrus orchard, a seasonal garden harvested by on-site restaurants, walking paths and a grand lawn.

Problem and Solution

Five Star Development, the developer of this project, wanted to make sure they preserved the natural beauty of the area so they proposed underground parking facilities to store guests' cars. In order for it to work on a tight construction schedule, the two proposed garages had to be built simultaneously. 

However, this move meant the original specified waterproofing product, a peel and stick membrane, was not going to be an ideal solution as it would take too much time to install. To help speed up the schedule and stay on deadline, Five Star chose to use EPRO’s E. Protect Wall Protection System for the perfect fluid-applied waterproofing system.

Insights From the EPRO Manufacturers Representative

EPRO e.spray fluid applied system utilized at the Ritz Carlton.

"The General Contractor saw the value in using EPRO’s e.spray fluid-applied system over the competitor’s sheet goods because of its ability to be applied on green concrete (uncured concrete), which helped speed up the construction schedule,” says Tom Shuey, EPRO manufacturer’s representative, Section 7 Marketing.

“An additional benefit is that the monolithic final product is fully adhered to the concrete and doesn’t have seams in which there is a greater chance for failure.”

Unlike competitors, EPRO is able to provide robust warranties for all its products and projects, including the Ritz Carlton project.

Tom told us, “The owner was extremely pleased with the fact that they could get an extended 20-year labor and material warranty with the EPRO system. It was a benefit to the system and was maybe not possible to achieve with the original, specified product, which was not by EPRO.”

Tom Shuey and the rest of the team were incredibly impressed with EPRO’s solutions. “The e.spray is a water-based spray-applied polymer-modified asphaltic emulsion that utilizes a proprietary catalyst that helps it cure quickly and allows for faster production times,” Shuey adds.

“The waterproofing crew for Progressive Roofing was very pleased with the application rate and are having no problem keeping up with the schedule on this massive project.”

EPRO’s Solutions at Ritz Carlton

The GC of the Ritz Carlton project chose the E.Protect Wall system for its commercial building waterproofing needs, thanks to its durability, warranty and speed of application.

At one story below grade, EPRO’s E.Protect Wall system, made up of three layers (e.spray 80 mils, e.shield 115, and e.drain 6000), was used to waterproof and protect the space. In total, 60,000 square feet of product was applied over this site.

The E.Protect Wall system is ideal for below-grade building foundations that require underslab waterproofing protection but have site conditions or budget considerations that might not require an additional layer of bentonite protection.

It can be used in conjunction with other E.Series systems and is designed to handle a wide variety of positive side-wall conditions while providing enhanced protection against common backfill materials.

It’s appropriate for all different types of over-excavated wall construction, two-sided formed walls, single-sided shotcrete, precast concrete, insulated concrete forms (ICF) and concrete masonry units (CMU).

The E.Protect Wall system has several benefits:

  • Redundant waterproofing protection.
  • Provides the highest level of chemical resistance to a wide range of contaminants found in soil and groundwater. 
  • Seamless.
  • Complete mechanical bond with vertical foundation walls. 
  • Installs quickly with less weather sensitivity than peel and stick systems. 
  • Designed for over-excavated walls of any depth.

Plus, EPRO offers a wide range of warranty options for its E.Series systems, including a No-Dollar-Limit labor and material warranty.
