Central Concrete Provides Expertise and High-Strength Concrete to Create 3D Model, Showcasing the Unique Underwater Topology at Point Lobos State Marine Reserve

Carmel, Calif., May 12, 2014 — Central Concrete Supply Co., Inc. a business unit of U.S. Concrete, Inc. (NASDAQ:USCR), was recognized for its expertise and contributions that greatly assisted in the development of a finely detailed, 3D model of the Point Lobos State Marine Reserve. The 800-pound concrete model was unveiled to the press and public on Saturday, May 10, 2014 at a ribbon-cutting ceremony at Point Lobos State Park, located along the central coast of California, just south of Monterey and Carmel.

Until now, the only way to experience the underwater landscape of the Point Lobos State Marine Reserve – a 9,907-acre underwater Reserve – has been to secure one of 30 permits issued each day to proficient divers. Even then, without the guidance of someone extremely familiar with the territory, you would be unlikely to know where you have been while seeing the extraordinary kelp forest, schools of fish, and friendly seals.

Imagine knife-edge structures as tall as skyscrapers; giant pinnacles undamaged by the erosion of their land-based counterparts; chasms barely wide enough to swim through; ledges dropping into unfathomable depths; topography that was above water during the last ice age, preserved much as it might have looked thousands of years ago when humans first camped on this shore.

Thanks to the efforts of some dedicated dive members, including the Bay Area Underwater Explorers (BAUE) and Central California Council of Diving Clubs, Inc. (CenCal), California State University Monterey Bay, community groups, and Central Concrete Supply Co. Inc., visitors to Point Lobos will now be able to visualize the undersea world—without getting wet.

Central Concrete Provides Expertise to Meet Model’s Challenges

The high level of detail to be conveyed by the model provided unique challenges. To address these challenges, Central Concrete’s Quality and Assurance Lab developed small samples to examine how best to reduce any small surface imperfections and holes and deliver the high level of detail.

The tests led the team to develop a high-strength (12,000 psi) grout. This high-flowing mix included white cement, sieved fine sand and various chemicals to meet the stringent requirements of the project. The chemicals included: high-range water reducers for optimal flow, viscosity modifiers to maintain cohesiveness, shrinkage reducing admixtures, defoamer to reduce air-voids and microfibers for additional bonding. Under the surface mix, Central Concrete used a high-strength, lightweight concrete, which incorporated macro structural fibers.
