FM1 is the best in category

Recommended FF/ FL numbers for slabs on ground ASTM- E 1155 standard testing standards for measuring floor flatness and floor levelness

FF numbers Floor flatness

FL numbers Floor levelness

FM1 Where very high standards of flatness and levelness are required. Reach trucks operating at above 13m without side shift.

4.5 1.8

FM2 Reach trucks operating 8- 13m without side- shift 6.5 2.0

FM3 Retail floors to take directly applied flooring. Reach trucks operating at up to 8m without side-shift. Reach trucks operating at up to 13m with side-shift.

8.0 2.2

FM4 Retail floors to take applied screeds. Workshop and manufacturing facilities where MHE lift heights are restricted to 4m.

10.0 2.4

Industrial floors should have an appropriate flatness in order to provide a suitable surface for the

operations of the material handling equipment and appropriate levelness to ensure that the building

as a whole, with all its static & mobile equipments (e.g., mobile partitions, racks, shelving, etc.) can

function satisfactorily.

Note: F- number system and TR34 rely on the same basic properties of flatness and levelness.

However, methodology of measurement is different. Hence, specifications should be selected by the

flooring expert after reviewing customer requirements.



Flooring measurements & certification

Measuring standards for defined movement floors

ACI- F-min system Longitudinal F-min Transverse F-min

TR34 DM classification DM1 | DM2 | DM3

DM1 is the best in category

Defined movement floors are commonly constructed in warehouses with very narrow aisles VNA’s, where vehicle path is restrained by rail or wire guidance system. In most of the cases aisle width is up to 2m. Reference pic on following page.

Note: Survey is carried out on the wheel pathways of MHE. DM survey method have no relevance to the areas of the floor under the racking.

Sub- base compaction testing

Industry practice is to plan and execute grading operations so that the final sub-base layer

elevation is at the theoretical bottom of the slab on ground immediately before commencing

concrete operations. Sub-base has three main purpose:

1. It is a working platform for the construction activity.

2. It provides level formation for the construction of concrete floor slab. Therefore,

consistency of slab thickness depends on the level tolerances of sub-base.

3. Sub-base transmits the load from concrete slab to the sub-grade.

Measuring standards ASTM E2835- 11

Test type Dynamic plate load test

Evaluations Evd (MN/m²) Testing of modulus of deformation within the framework of sub-grade/ base examination

Testing surface type Sub-grade and other unbound mixture as described in TR34 flooring specifications
