Pour, crack, fill, repeat. It might sound as if this is a recipe for baked goods, but for Angelus Waterproofing & Restoration, Inc., it was the daily schedule for a year-long construction cycle. The underground Silver Lake Reservoir, built by the Los Angeles Department of Water and Power, covers an area the size of 6 or 7 football fields in northern Los Angeles. There are a lot of people living there so it’s a big structure, and it needed to be repaired as it was being poured.

Creating dedicated open park space in densely populated urban areas is a consistent challenge for city planners. One innovative approach is to install green-roof systems on existing structures within the city limits. For example, in Chicago, Ill., an entire network of interconnected parks is built on top of underground parking garages. They comprise the largest parking facility in the United States!

It’s a too common occurrence to turn on the news and witness some form of hazardous chemical release into the waterways, ground, or atmosphere. These dangerous events have garnered a much greater public concern over the past 25 years, and social media and camera phones help to keep them in the forefront.

Concrete and polyurea seem to go hand in hand in the secondary containment world. This winning duo was no different at the Leffler Energy jobsite in Lancaster, Pa., when the containment that was supposed to be protecting the ground from accidental oil spills started showing signs of aging.

Midwest Industrial Coatings promised to deliver.

What do you do when a food facility receives a less-than-par coating? When that happened to a client’s floor on the West Coast, the only thing the client and manufacturer could do was move forward together. The coating system, which was not initially installed correctly and therefore didn’t look right, needed to be fixed.

When Tokyo Rhino, a coatings contractor in Japan, got the call for a restaurant floor project in the Kanto region, they knew their exclusive distribution agreement with the U.S.-based Rhino Linings Corporation was the ideal match for the job.

The building was undergoing a bit of a remodel and that included a rehab and some new coatings for their facility’s floor. “It was pretty rough,” Keener said of the floor’s original condition.

Concrete is a very strong, durable material, and it is the primary substrate on which flooring materials are applied. What is well documented but seemingly not well understood are the problems that moisture can cause on a concrete floor that has been coated with non-breathing flooring materials.

For the three-person crew from Tri-State Painting, it was the chemical cleaning portion of the job that called them to a water treatment plant in the Keystone State.
