On the west-bound lane of I-40 in Arkansas, the West Memphis DOT inspection facility lies immediately west of the Hernando de Soto Bridge, which crosses the Mississippi River from Memphis, Tennessee. The Arkansas DOT uses the inspection pit on the I-40 to examine the underside of westward-bound trucks and heavy vehicles to conduct safety inspections, such as brake and suspension tests, and also to check for any illicit substances that may be attached to the undercarriage of the truck.
Penetron worked with the R.L. Persons team to devise an optimal solution to protect all exposed concrete at the DOT inspection facility. Razorback Concrete Company, the ready-mix supplier, added PENETRON ADMIX to the new concrete used for the foundation slabs and retaining walls of the inspection pits and facility building. PENEBAR SW-45 waterstop strips were used to seal the construction joints. In addition, PENETRON crystalline material was applied topically to almost 3,000 square feet of existing concrete structures – in combination with PENECRETE MORTAR to seal the cracks in the existing concrete – to extend the durability of the structures.
