FREQUENTLY ASKED QUESTIONS

CONCRETE MOISTURE

WHAT IS CONCRETE MOISTURE TESTING?

Concrete Moisture Testing is the method for determining relative humidity in concrete floor slabs using in-situ probes.  In short, holes are drilled into a concrete slab and a sensor placed into each hole for accurate measurement.

 

WHY DO I NEED CONCRETE MOISTURE TESTING?

Concrete Moisture Testing helps to prevent additional costs and delays of moisture related flooring failures.  More recently, flooring manufacturers are adding moisture testing to their installation requirements and without such testing are now voiding all warranties.

 

WHO NEEDS CONCRETE MOISTURE TESTING?

Concrete Moisture Testing is necessary on all floor projects.  Owners, Property Managers, General Contractors, and Architects all stand to benefit from accurate third-party Concrete Moisture Testing performed by Certified Concrete Slab Moisture Test Technicians.

 

WHEN SHOULD CONCRETE MOISTURE TESTING BE COMPLETED?

Concrete Moisture Testing should be completed prior to laying your flooring and after the concrete slab has reached service temperature and the ambient room conditions are at service temperature and service relative humidity for at least 48 hours.

 

HOW MANY CONCRETE MOISTURE TESTS ARE NEEDED?

Per Industry Standard ASTM F2170, the appropriate amount of tests necessary is 3 tests for the first 1,000 SF and 1 test per each additional 1,000 SF.  Examples:  5,000 SF slab requires 7 tests; 10,000 SF slab requires 12 tests; 20,000 SF slab requires 22 tests.

WALKWAY SAFETY

WHAT IS WALKWAY SAFETY / DYNAMIC COEFFICIENT OF FRICTION TESTING?

Walkway Safety Testing is the method for measuring the wet dynamic coefficient of friction (DCOF) of common hard-surface floor materials.  In short, measurements are taken to determine the slip resistance potential of the subject floor material.

 

WHY DO I NEED WALKWAY SAFETY TESTING?

Walkway Safety Testing aims to help prevent costly slip, trip and fall incidents by accurately measuring the potential slip resistance of flooring materials and by providing industry-accepted action and limit thresholds for facilitating remediation of walkway surfaces when warranted.

 

WHO NEEDS WALKWAY SAFETY TESTING?

Walkway Safety Testing is essential for addressing the slip resistance potential of common hard-surface floor materials such as ceramic and porcelain tile, polished concrete, stone, vinyl floor coverings, wood and synthetic laminates, and such materials with coatings or polishes applied.  Owners and Property Managers benefit from accurate third-party Walkway Safety Testing performed by Qualified Walkway Auditors.

 

WHEN SHOULD WALKWAY SAFETY TESTING BE COMPLETED?

Walkway Safety Testing can be completed on installed or uninstalled flooring materials.  Each test represents only the current conditions of the subject flooring materials and, therefore, scheduling routine and regular testing for the most comprehensive summary of slip resistance potential.

 

WHAT IS DYNAMIC COEFFICIENT OF FRICTION?

Dynamic Coefficient of Friction (DCOF) is defined as the ratio of the horizontal component of force applied to a body required to overcome resistance to movement when the body is already in motion divided by the vertical component of the weight of the body or force applied to the surface where movement occurs.

DCOF values above 0.42 (0.45 on inclines) are considered to have a high slip resistance potential offering a lower probability of slipping.   DCOF values between 0.30 and 0.42 (0.30 and 0.45 on inclines) are considered to have an acceptable slip resistance potential offering an increased probability of slipping.  DCOF values below 0.30 are considered to have a low slip resistance potential offering a higher probability of slipping.

FORENSIC ENGINEERING

WHAT IS FORENSIC ENGINEERING?

Forensic Engineering is an investigation into all components of a personal injury or property damage incident to locate cause(s) of failure to assist in documenting the facts of such an incident.
