Floor Surveys & Testing
Flatness Testing
DFS use the latest in digital measuring equipment, to check both Defined and Free Movement floors to TR34, DIN or the American F number specifications.
Free Movement
Free movement floors refer to areas where materials handling equipment operates in random, non- defined directions and have an infinite number of travel paths. Floors in manufacturing, retail and distribution, where materials handling equipment is free to move in any direction, are measured by DFS, in accordance with:The Concrete Society’s TR34 FM specifications ASTM E1155 FF & FL Numbers ASTM E1486 Waviness Index ASTM E1486 Pitched Floors & Elevation Conformance DIN 18202.In addition, surface regularity can be checked to ‘BS8204 – Part 2:2003’ straight edge specifications SR1, SR2 and SR3.
Defined Movement
Floors in very narrow aisle racking systems have materials handling equipment that runs in defined and fixed paths between the racking, such as very narrow aisles. The floors are measured with Face Profileographs of slightly differing configurations. The Concrete Society’s TR34 Chapter 4 and Appendix C ASTM E1486 Defined Wheel Path Traffic The ACI F min number system DIN 15185.
Abrasion Resistance Testing
Abrasion resistance is an important performance requirement in warehouse and industrial floors. Floors can be exposed to quite aggressive actions from trucks and other equipment, particularly in factory environments.
Pull Off Testing
Evaluate the pull off strength (adhesion) of a coating (e.g. screed or topping) from a rigid substrate such as a concrete or metal floor. Testing will be in accordance with the British and European standard BS EN 13892-8:2002.
Humidity Testing
Check whether the moisture level of the concrete slab or screed has reduced to a value where flooring can be safely laid. The relative humidity of a concrete floor can be checked in accordance with BS8203:2001 or using the humidity sleeve method.
Cover Meter Testing
Using an electromagnetic cover meter the position, depth, and size of reinforcement buried in concrete can be estimated. Testing can be carried out in accordance with the recommendations found in BS1881-204:1988
