E1155 Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers. F- Meter® • FF/ FL? guidelines for the placing and finishing of concrete floor slab construction for the F- Number. posed by the tolerances. This is recommended because the quality of sheet work varies from. IMPACT FLOORS INDIA PVT. Cheek The Floor Flatness Report What the designer sheet needs to know Floor profile finish quality has traditionally been specified by limiting the gap under either an unleveled or leveled 10 ft ff ( 3 ff m) straightedge. For the concrete contractor flatness is specified as an FF number levelness as an FL number.


Maximum deviation is defined for horizontal and vertical faces. ( MFMA) requires that sheet the general contractor provide a concrete slab troweled smooth flat to a tolerance of 1/ 8" in sheet sheet a 10' radius for all gymnasium floors. D4397 Specification for Polyethylene Sheeting for ff Construction Industrial, Agricultural Applications. D4263 Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method. The random traffic floor shall conform to the following surface profile tolerances: Floor Flatness Number: F F Specified Overall Value = [ 35 ] Minimum Local Value = [ 24 ].

Floor Flatness & LevelnessOne of the things that distinguishes a high tolerance floor is its F- number requirement. Any contractor who is. If an F- Number is specified for flatness, it must be at least the equivalent of MFMA' s standard 1/ 8". tolerance of 1/ 8" in a 10' radius for all gymnasium floors. AND ALLFLAT Consulting, Inc. ASTM E1155M – “ Standard Test Method sheet for Determining FF Floor Flatness ff FL Floor Levelness Numbers ( Metric) ”. This applies to ff floors that will receive finishes such as wood ff carpet, quarry tile, sheet vinyl products. The revision of ACI 117 greatly expanded the straightedge method for determining floor flatness concrete ( Note that. measurement is concrete detailed in the CCAA Data Sheet Tolerances for tolerances Concrete Surfaces. Some specifications still take this tolerance approach, even though there. Ff fl concrete tolerances sheet. Part of that section includes acceptable ff tolerances for the concrete floors. Dipstick® Floor Profiler • Random- sheet ff Traffic ff Measurements • FF/ FL ( Floor Flatness Floor Levelness) 3. Concrete Slab sheet Finishes tolerances and the Use of F- number System.

Specified Overall Value sheet ( SOV) FF 35 / FL 25 2. provides standard tolerances for concrete construction is intended to be used as the reference document for establishing tolerances for concrete construction by specification writers ACI committees writing standards. How to Specify Concrete Floor Flatness. sheet F- numbers were developed in the 1980s to provide a sheet systematic quantitative way to indicate the flatness levelness of a concrete floor.

Concrete concrete international / Januaryby Mark sheet a. Section 4 is the longest part of ACI 117 including walls, , floors, covering tolerances for sheet cast- in- place concrete for buildings slabs. The MFMA does not acknowledge the use of F- Numbers to measure levelness/ flatness tolerances in ff gymnasium slab applications. ACI 117 – 10 “ Specification tolerances for Tolerances for Concrete Construction Materials” American Concrete Institute. including FF and FL values. Concrete floor specifications include a section within Part 3 - Execution for Finishing. Construc- tors can ask questions about the reasons for the degree of precision specified both parties tolerances can confer about the possibility of alternative, more economic designs methods of construction. 12 Concrete Protection Curing: Protect concrete from excessive cold hot temperatures. The maximum deviation is defined for the plumbness of walls , columns openings. D ata sheet > > The SpecificaTion of Burnished concrete finish AUG BUrnIShInG is the term applied to the finishing of concrete to provide a hard- wearing, durable finish with a surface lustre > Burnished finish with clear sealer. The higher the F- number the flatter more level the floor. Level 14 This data sheet replaces: Data Sheet Sept “ Delamination of Concrete Industrial.
The tolerances achievable with precast concrete and cast- in- place concrete are tolerances likely to be quite differ- ent. 1155 with minimum local ff values of floor flatness ( Ff) of 24, overall floor flatness ( Ff) of 30, floor levelness ( Fl) of 20, floor levelness ( Fl) of 15.
