www.concreteproducts.com February 2017 • 81 INNOVATIONS REPORT LICENSED PRECAST INDUSTRIAL KNEE WALL Adapted from the Basement design, Industrial Knee Walls exhibit the versatility of pre-insu- lated walls with the strength and durability of concrete. They are offered in a standard 8-ft. configuration to serve as the 'hardwall' aspect of pre-engineered metal buildings—erected in shorter windows than alternative base wall types. Cast in 20-, 25- and 30-ft. lengths, Knee Walls allow for various column bay spacing, and can be adjusted to meet intermediate and end conditions as project specs require. A variety of connection types can be employed. Tiebacks can be achieved at the top by use of Halfen anchor channels with the straps welded to steel angles bearing on pri- mary building columns. For base connections, solid concrete areas are provided for bolted attachment of a clip angle, secured to the floor slab with a variety of post-installed anchors. L-WALL L-Wall is a precast, pre-engineered retaining wall system, available in 4-ft. widths and up to 16-ft. heights for a maximum finished grade differential of 13 feet. Fabrication in a plant environment enables simultaneous wall cast- ing and site work, reducing overall construction time, and yields high quality concrete, tight tol- erances and improved finishes. The wall and heel thickness is variable from 7 in. to 14 in.; wall height and heel width are likewise variable. The system is pre-engineered for standard installations, but can also be designed to site-specific conditions. Walls have interlocking tongue and groove joints on the sides to help seal and align the finished structure. — Van- HooseCo Precast, Loudon, Tenn., 865/458- 3998; www.vanhooseco.com The Precast Show Booth 1187 ® Acti Gel 2 0 8 - Acti-Gel® 208 is a natural, low-dose, rheology modifier and mix stabilizer that dramatically improves the cost of concrete blocks.
