www.concreteproducts.com February 2019 • 61 INNOVATIONS REPORT RETAINING WALL BLOCK When conditions along a John C. Tune Airport hangar complicated plans for a retaining wall of standard units, licensee Redi-Rock of K.I.T. proposed an XL block solution to the Metropolitan Nashville Airport Authority. Engineer JC Hines & Associates reached a maxi- mum height of 25.5 feet using 806 36-in. high XL units of various widths, transitioning to 173 standard 18-in. Redi-Rock block along the top. The installation spans 10,200 sq. ft. of Ledgestone texture. "The new XL blocks at up to eight-feet wide allow for taller gravity walls than ever and are especially useful in applications where you've got limited room," notes Redi-Rock Director of Engineering Jamie Johnson, P.E. "With the addition of XL into the system, engineers can solve more problems with Redi-Rock. Whether you're designing for tall gravity walls, for heavy live loads with a mechanically stabilized earth wall using the Positive Connection blocks, or for the benefits of a large batter wall, Redi-Rock has solutions for just about every application." Beyond the potential for taller walls, he adds, integrating XL blocks into a retaining wall design offers such benefits as a) streamlining installation with twice as much face coverage for each machine- set unit; shipping cost savings due to hollow-core design; and, wall optimization through mixing and matching XL and standard blocks as conditions allow. Accompanying the XL block launch is a wealth of engineering and installation resources: preliminary height guides, software updates to both the professional and freeware versions, plus construction details. — Redi-Rock International, Petoskey, Mich., 866/222-8400; www.redi-rock.com/XL CONCRETE SOLUTIONS FOR CRANES, HOISTS & WORKSTATIONS '*#*(%'$#% "%* *))&*"$*()&* )#&'*(*))&")%!)*"%*$)*&)!#'$*!(%!&)$)* "% '$&**"'*(&*($(*'(&!)*(&*()&)# #% *#%$&*!&#%)'*("'$'*!&#%)*"$'*#'*)*#' ')'$#% "%* *(&'$#$"(%*!&#%)'* & )&*&(*(&*"%)*(*'$#% #& *!&#%)'*(&*#'*'* $(*!'$()%"%))&*#*'($"(%*$(*"$*(&*!'$( %)) '*)&"!)*"'')'**(*(&*!&#%)'*("'$'* #% *!((%)%$*'($"(%'*#&)*')&"!) *$&(* #%*#$(&") *%#$"(%" )* )#)&*%)$(&* Call (330) 220-8600 • www.emhcranes.com Visit Us: Feb 2019-NPCA Louisville: Booth #608
