Despite inhibitions surrounding the use of silica sand, the term sandblasting is still widely-accepted in the vernacular of surface roughening applications. This stems back to the origins of artificial abrasive blasting technologies. The very first sandblasters were based on the natural weathering effect of aeolian erosion, which occurs when wind pervasively blows sand particles against a surface. It is a rudimentary process that has, nevertheless, persisted for over a century despite the comparative inefficiency of silica-based blasting media.

The 60,000 square foot irrigation pond will be used for landscape irrigation of the expansion of the park. After awarded the project, local general contractor, JD Enterprises, constructed the holding pond, piping, and pump house equipment with Unit Liner being hired for the protective liner installation, which was subcontracted to Greeley, Colorado-based applicator, Energes Services, LLC.

Property managers and developers throughout the U.S. turn to Pavecon for a higher level of competence and craftsmanship. Since 1992, they have earned a reputation as one of the most respected, and respectful, paving companies in the nation.

SIPP pipe liners entered the market over a decade ago. Clients have always been interested in the potential of this alternative liner technology, desiring a viable alternative to Slip Lining, CML and CIPP.

Asset owners make significant investments in preventing the occurrence and spread of corrosion, as well as in repairing corrosion damage.

Oil and gas asset owners are increasingly looking for longer performance from their corrosion protection methods, but at the same time wish to reduce their overall capital expenditure budget in all areas.

Because terrorism is a growing occurrence in many parts of the world today, governments have amplified their hunt for new ways to protect people and property. ArmorThane has developed a powerful new polyurea spray coating to aid in that protection, UltraBlast.

Achieving total cleanliness will ensure longer-­lasting coatings. The final stages of surface preparation are the most critical and the most often neglected. Many of the available tools simply do not deal with late-stage surface preparation adequately or efficiently.

In order to preserve the concrete structures, the ideal plan of action has been to coat the concrete with a barrier material. These materials have typically been epoxy and urethane-based.

The purpose of this paper is to outline the results of testing, either directly or indirectly, the solar reflectivity of a coated roof surface as defined by ASTM C1549 using instrumentation that is not currently recognized by ASTM Subcommittee C16.30 for testing reflective roof coatings.
