Wal-Mart the retail sales giant specifies something a little different than mechanically polished concrete in Dallas Fort Worth, Texas. The actual finish specified is known as Light Weight Burnished Concrete. This is a much lighter system than heavy down-force mechanically polishing. However, this specific Wal-Mart requested a mechanically polished concrete in effort to remove an issue known as efflorescence at the surface. Efflorescence is a crystalline deposit on surfaces of concrete that is found at the surface of a slab under certain unfavorable efflorescence. This change allowed us to utilize our heavyweight grinders to hone and polish the slab. In doing so the customer ended up with a finish far superior to a burnished slab that will not only outlast but will look amazing over the entire life of the building. Per the CPAA the final finish is a Level 3 gloss with a Class “A” aggregate exposure. In addition to the polished concrete, the owner required all construction and contraction joints filled with Poly urea joint filler, which is seen in photo 3.
