Urethane, ceramic tiles withstand extreme wear in aggregate handling

Stone, sand and gravel can take their toll on material handling equipment for concrete production. The bare structure of transfer or storage components and vessels may not adequately resist wear, and even traditional steel or rubber protective liners can prove insufficient to withstand abrasion.

Crystallizing admixture seals stormwater storage structure

An unusually wet 2018 winter led to the official end of the worst drought in California’s history. But coastal Santa Monica, just west of Los Angeles, is maintaining water conservation targets for all residents, and undertaking several ambitious projects to advance supply self-sufficiency within the next few years. Efforts include wastewater recycling and construction of underground cisterns to capture storm runoff.

Earth Wall Products

Licensed retaining wall systems include the precast Forix and Gravix profiles for department of transportation, rail, industrial, commercial and residential markets. A triangular section in the stem, cast perpendicular to the retaining wall face, allows the weight of the backfill to bear on the units, thereby transferring downward pressure and resulting in a stabilizing effect.

Uwall Systems

Company has recently added New England Drystack as an alternative to its Rectangular Cut Stone face, both offering fast, economical solutions for most retaining wall conditions. Product engineers present Uwall as a fully engineered, steel-reinforced structure with inherent economies when compared to solid, plain concrete blocks. Its biggest advantage is the ability to save contractors or installers time from offloading deliveries to setting the wall block. Since each piece weighs about 4,000 lbs. and averages 32 sq. ft. of wall face—versus 6 sq. ft. on a typical ‘big block’ precast unit—producers can a) deliver about 75 sq. ft. more product on each truck, with 11 pieces totaling 352 sq. ft.; and, b) reduce the number of project loads by about 40 percent and number of sections to set by upward of 75 percent.
