In addition to producing a full line of precast concrete products, C.R. Barger and Sons is the licensed Stone Strong manufacturer for the state of Tennessee and supplier to surrounding areas.
Haven’t heard of Stone Strong? The Stone Strong retaining wall system is being used on a high profile project right here in East Tennessee! Stone Strong blocks are being used on the Federal Highways Foothills Parkway where the walls are approaching 50’ tall. The project will also have tiered walls approaching 70’ tall. The Stone Strong retaining walls are literally holding back the mountain!
Stone Strong has been approved by TDOT since 2009 for use as a concrete gravity wall product.
Now that you know the Stone Strong block can do the job, let’s look at how it stacks up against the competition. The three main advantages of the Stone Strong block is the increased gravity wall height with no tiebacks, the speed of installation resulting in schedule and labor savings, and built-in internal drainage. For walls under 12’, geogrid can often be eliminated during engineering design. We have found the Stone Strong block to be very competitive, especially when the finished wall cost is compared.
Stone Strong retaining wall systems allow an installer to set 24 sq. ft. of retaining wall in one block set! It takes the same amount of time to set one engineered retaining wall block, no matter the size; therefore, the installer can set more square feet of wall at a time, and the total number of blocks to set is significantly reduced. With its built-in alignment loops, Stone Strong blocks set quickly and interlock with an automatic 4” setback for every 3’ tall course. The block voids are filled with aggregate during install, providing additional connection strength. The top blocks have an angled front face so the backfill or finish landscaping can be pushed up to the front edge of the top block. Also, the void in the block allows for easy installation of fence sleeves to quickly install a fence at the top of the finished wall without coring.
Did you know the Stone Strong block can also be used for bridge abutments and wing walls.
We have a short informative project highlight video on our website from Midway Middle School where Stone Strong block was used to replace a failed retaining wall. This video shows highlights of the install from start to finish.
Let’s take a quick look at the standard block.
The 24 SF Block, the largest block face, has dimensions of 96"W x 36"H x 44” D. This block weighs 6000 lbs. The 6 SF Block has dimensions of 48"W x 18"H x 44” D. This block weighs 1,600 lbs. The 3 SF Block has dimensions of 24"W x 18"H x 44” D. This block weighs 800 lbs.
The 24SF mass extender block is a specialty block used on the base course of taller walls to eliminate geogrid. The dimensions of the mass extender block are 96"W x 36"H x 56” D. This block weighs 10,000 lbs.
Stone Strong’s photos give a great representation of the many uses of the Stone Strong block and prove the Stone Strong block creates a strong and aesthetic retaining wall, easily fitting into any landscape.
We provide engineering design services and work closely with lead engineers, geotech engineers, installers and owners to ensure we optimize the wall design to create a successful project at a competitive price. For local jobs, we also provide on-site technical support as needed to get an installer started and have done aerial video and photography to document jobs.
