Constructing a superflat concrete floor slab.

The next critical step is to float the slab with a power trowel and cross rod to obtain the high flatness requirements of a super flat floor. Al though superflat slabs are placed in long narrow strips approximately 15. While moving down the aisles these lift trucks can. The slab is troweled over several times with a power trowel and cross rodded to achieve the required super flat tolerance.

See astm e 1155 standard test method for determining ff floor flatness and fl floor levelness numbers. We strongly recommend the following for building owners and their representatives when specifying and designing superflat floors. Strip pouring is mandatory. Such floors have very specialized applications narrow aisle warehouses but the techniques used to place these special floors can be used in less demanding applications or when required in specifications.

Aci 302 1r 04 guide for concrete floor and slab construction defines several classes of floors based on their intended use and the suggested method used for final. Same route over and ove r the smoothness of the wheel paths in superflat aisles becomes extremely important. There are two basic floor categories.

We have been involved at every level of concrete construction and are responsible for creating the chemical processes adopted on an international scale for meeting industry specifications for robotics and other use. As building owners become aware of the benefits of superflat defined traffic specifications for concrete floors the popularity of these specifications will. In very narrow aisle warehouses forklifts travel 6 foot wide aisles between storage racks with the aid of rack mounted rails or a wire guidance system embedded in the floor. True for the amount of concrete that must be removed to make an ordinary random traffic ff fl floor a defined traffic superflat floor.

Random traffic and defined traffic. Aci s guide for floor and slab construction aci 302 1r 96 defines a superflat floor class 9 as one with fmin number greater than 100. This industry standard revolutionized the way the concrete construction world understands and perfects concrete floor finishing.
