| 20090277127 | DECORATIVE AGGREGATE CONCRETE SURFACE PREPARATION PROCESS - The present invention is directed to a process of creating a decorative aggregate concrete surface on both a slab on grade installation and a podium deck or topping slab installation. The preparation includes washed decorative aggregate surfaces using a variety of decorative aggregate materials imbedded within a standard concrete mix having a one inch maximum aggregate. A 6-mil polypropylene sheet 435 Visqueen material covered with a two-inch layer of sand is used directly below the concrete to retard the curing time. Roller tamping is used to move the large aggregate below the surface of the concrete material. Power brushes are then used to expose the decorative aggregate prior to the final process of applying a densifing sealer. This process has been designed to reduce installation time, as well as overall labor and material costs. | 11-12-2009 |
