The Best Source

Hardscape North America (HNA) 2012 is set for Oct. 24-26 at the Kentucky Exposition Center in Louisville, Ky. Visitors will benefit from a lineup of comprehensive educational sessions with topics ranging from best practices in business management to installation techniques. The conference program will be packed with valuable information presented by expert speakers.

The keynote speaker for the Hardscape Contractor Executive Workshop is Ed Fioroni, PhD. and former Chairman of the ICPI Board of Directors. His presentation will include an interactive exercise, discussing specific examples of how existing customers can be retained, and how customer contact information can be utilized in marketing efforts to generate new business.

ICPI Certified Installers can earn up to 8 continuing education credits by attending the HNA Conference Sessions and Demonstrations.

In it Together

The American Society of Civil Engineers (ASCE) recently formed a project team to draft a national standard on structural and hydrologic design of permeable interlocking concrete pavements. The project team is drafting a standard in the coming months and ASCE will form a standards committee to critique and ballot the draft. This standards-making process takes about four years.

Class Is In

ICPI is offering a new advanced-level, classroom-based course for residential paving. The Advanced Residential Paver Technician Course expands upon the Concrete Paver Installer Course and specializes in overlays, multi-levels, fireplaces, grills and outdoor kitchens, pool decks, material calculation and advanced business practices.

The program has been developed by some of the industry’s top contractor instructors. It is intended for owners of paver installation companies and jobsite foremen involved in residential paver installations.

The course spans two days, and upon successful completion of the final written exam participants will receive a Record of Completion. Additionally, designation as a Residential Paver Technician can be conferred upon the participant if he has met the minimum installation experience requirements.

Registration The two-day course costs $250 for ICPI members and $350 for non-members. To enroll, go to the Calendar of Events on the ICPI website and register online for your preferred session.


Tools & Tech

Bon Tool, maker of tools for segmental pavement contractors, introduces their V-Angle Wire Brush for cleaning tight Paver Joints. The V-angle and tough wire bristles make cleaning mud and dirt from tight paver joints easier, and can be used on permeable interlocking concrete pavement.

A Senator’s Pledge

On May 3, ICPI met with many of its members in the Louisiana concrete paver industry to host U.S. Senator David Vitter (R-La), a member of the Senate Committee on Environment and Public Works, for a special product demonstration and briefing session.

More than 30 concrete paver executives met at the Wilson Charter School in New Orleans, the site of a high-profile paver installation. The group demonstrated a simulated ASTM surface infiltration test to show how permeable concrete pavement systems allow for stormwater infiltration. They also briefed the Senator on the public policy benefits offered by concrete pavers.

Sen. Vitter was instrumental in retaining the permeable pavements provision in the final House-Senate version of the Transportation Reauthorization Bill passed into law on July 6.

Sales on the Rise

Sales data from the most recent ICPI Industry Sales Survey indicates a 2.7 percent increase in total U.S. paver sales and a 7 percent increase in Canadian paver sales from 2010 to 2011. The commercial/municipal markets represent 21.3 percent of total sales; 78.7 percent is residential sales.

Permeable pavement sales have steadily increased over the last three years, growing from 3.8 percent in 2009 to 5.1 percent of total sales in 2011. In 2011, 78.4 percent of permeable pavements sales were used in commercial applications and 21.6 percent in residential.

ICPI’s Industry Sales Survey is conducted annually to gauge the health of the industry. The survey represents the most accurate and up-to-date sales information available for the North American interlocking concrete pavement industry. The survey data applies to all products that conform to ASTM C936 or CSA A231.2.

The 2012 Survey reports on 2011 sales data from 69 concrete paver companies and projects estimated annual paver sales from a same respondent sample to the universe of paver manufacturers.

The complete survey, which also includes data for the North American concrete paver, concrete masonry and segmental retaining wall industries, is available for sale for $99. ICPI members receive a discount. To order, call 412-741-1892 or online at


Good To Go

Since concrete paving units have many shapes and thicknesses, their compressive strengths vary, and these strengths decrease with increasing thickness (like all concrete, steel and wood materials). To better address these differences, ASTM recently approved standardized compression test specimen sizes that normalize compressive strengths to that for a 2 3/8 in. (60 mm thick) rectangular (98 x 198 mm) paver.

Standardizing the specimen size allows for more consistent and comparable strength test results. Research by the Interlocking Concrete Pavement Institute resulted in a uniform dimensional range for test specimens and compressive strength test methods soon to be included in ASTM C140 Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units.
