A Sample Specification for Welded Wire Reinforcement (WWR) 2006, 6 pages
We have had many requests for an example of a Sample Specification that design and construction professionals may review when preparing their own construction documents. This is a sample specification prepared by an engineer with a WRI member producer. (Please review the WRI Disclaimer attached at the end of the document.)
WRI Tech Facts
TF 702-R-08: Supports Are Needed for Long-Term Performance of Welded Wire Reinforcement In Slabs-On-Grade Updated 2008, 6 pages
The questions of "why" and "where" supports are necessary are covered in this publication. Types of supports for WWR and the influence of the sub base conditions on their selection are addressed. Suggested spacings of supports are furnished to show the different spacings when wide spaced WWR (step-through styles) is specified vs. the smaller spaced styles.
TF 704-R-03: High Strength Welded Wire Reinforcement Compared with Rebar 1995, 2 pages
This Tech Fact shows an actual distribution facility project that saved considerable costs on the placing of WWR compared with rebar. The high strength WWR saved material costs alone to convince the owner and contractor to use WWR. The contractor's statements give credence to the importance and viability of the use of WWR over rebar in concrete paving, parking lots, and slabs-on-ground.
WRI Case Studies
CS 1-2005: Case Study - Properly Placed WWR Provides Quality Concrete Sidewalks. 2005, 2 pages
Case study describes the use of structural welded wire reinforcement in the construction of sidewalks in New York City.
CS 3-2008: Bridges, Walkways and Approaches 2008, 4 pages
Structural Welded Wire Reinforcement Proves a Superior Choice in the Transportation Sector.
CS 194-R-03: Case Study - Multiple Uses, One Project - Jacob's Field, Cleveland Indians Ball Park, Cleveland, Ohio 1994, 4 pages
Examines use of 490 tons of high strength WWR for paving, slabs-on-grade, supported corridor slabs, precast units, and beam shear cages. Value engineering played a big role in saving money and helped construction stay ahead of schedule. Cost savings of $125,000 were realized by reduced forming turnover time and placing time. By using high strength WWR over conventional strength reinforcing, 15% of the material costs were saved.
CS 299-R-03: Case Study - Research Results - High Performance Can Be Achieved with Welded Wire Reinforcement in Paving & Slabs when Proper Cover Exists 1999, 4 pages
A case study of 3 projects that were researched by Prof. Luke Snell include two industrial slabs - one 3 years and the other 11 years old. The Il DOT interstate paving study is over 30 years old. The study shows that when properly placed and supported WWR exists, high quality and long term performance can be expected.
