Noun 1. products in the marketplace and their abilities to deliver durable, maintenance-free concrete flatwork. PNA's Diamond Dowel(R) System and PD3 Basket(TM) assembly provide load transfer and continuity of surface profile in concrete slabs-on-ground.
The favorable conclusion relied upon the validity and enforceability of U.S. patent # 6,354,760 that covers the Diamond Dowel(R) System, a product used extensively nationwide since 1997. PNA won a permanent injunction permanent injunction n. a final order of a court that a person or entity refrain from certain activities permanently or take certain actions (usually to correct a nuisance) until completed. against products manufactured by a former employee, upholding its tapered plate dowels as the premier doweling dow·el

"PNA respects and supports innovation of products for the concrete construction industry but it cannot condone condone v. 1) to forgive, support, and/or overlook moral or legal failures of another without protest, with the result that it appears that such breaches of moral or legal duties are acceptable. willful infringement of its intellectual property," said Sue Wooldridge, vice president, PNA Construction Technologies. "We have a heritage of engineering and inventing products that help designers and concrete contractors reliably deliver durable concrete flatwork that building owners demand. We are committed to developing further innovative products for 'strategic reinforcement' designs that lower project costs and provide modern floors for today's industrial, commercial and retail uses."
In industrial, warehouse and big box retail construction, tapered plate dowel technology prevents joint deterioration that can directly reduce logistics productivity, increase building maintenance costs and machinery repair costs and cause potential trip hazards for employees and consumers. Tapered plate dowel technology enables contractors to deliver stable joints in concrete flatwork without introducing negative side effects Side effects

"PNA's plate dowel systems have been used in more than a billion square feet of concrete slabs-on-ground and have consistently helped contractors improve their profitability through the reduction of callbacks," adds Wooldridge. "With materials price volatility and trends toward reverse auction bid situations, both contractors and engineers need cost effective solutions they can offer while delivering on the owner's expectations. A slab-on-ground 'strategically reinforced' with tapered plate dowels eliminates more than 72 percent of the steel you would expect to find in conventionally reinforced slabs."

A shallow, reinforced-concrete structural member that is very wide compared with depth. Spanning between beams, girders, or columns, slabs are used for floors, roofs, and bridge decks. by increasing the bearing area of the dowel at the joint thereby reducing the bearing stress in the concrete. The tapered shape permits parallel and perpendicular movement at the construction or saw-cut contraction joint, eliminating restraint of the concrete.

Binding agent of present-day concrete. It is a finely ground powder made by burning and grinding a limestone mixed with clay or shale. Its inventor, Joseph Aspdin (1799–1855), patented the process in 1824, naming the material for its resemblance to the Association guidelines since 2000.
Founded in 1986,is the industry leader in performance products for concrete flatwork that provide durable, maintenance-free floor slabs. PNA engineers and manufactures a range of products for providing load transfer, joint protection and slab surface continuity, including the Diamond Dowel(R) System, PD3 Basket(TM) assembly, Load Plate Basket(TM) assembly, Armor-Edge(TM) joint assemblies and HydraCure(TM) single and multi-use curing covers.
The Diamond Dowel(R) System has been industry accepted since 1999, and reached a company milestone in 2002, when it became a standard specification for several national big box retailers. Today, PNA products are in widespread use in concrete flatwork throughout North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. and 20 countries worldwide. PNA's tapered plate dowels have been used in more than 1 billion square feet of concrete flatwork.
