The Challenge
Hospital-associated infections (HAIs) like
MRSA continue to be a problem in health
care facilities
It is estimated that each year in the US:
• 1.7 million patients acquire HAIs
• 99,000 patients die from these
infections
• 5,000 HAI deaths result from
construction-related activities
• Studies indicate invasive aspergillosis
can occur during construction and
renovation
The Situation
 Feedback from our contractors indicated a
growing concern from health care
customers over increased patient
infections due to cross-contamination from
renovations and additions
 Health care organizations are in need of
construction professionals with the skills to
properly contain infectious agents on a job
site
 Specialized training – focusing on the
health care environment – is needed in
order for health care organizations to
renovate, alter, or expand facilities with
3 confidence
Best Practices in Healthcare
Construction Training
 Developed to train crews to minimize
risk of hospital acquired infections
related to construction activities
 Training teaches the best way to
protect the facility, workers, staff and
most importantly – the patients
 Goal is to create the most optimal
flooring installation conditions as
possible so that the floor does not fail
and contaminants are contained

Flooring & Healthcare
Facilities
87% of work is done without properly trained labor*
Improperly-installed floors lead to unsafe conditions for the
staff and patients, which causes...

Main Failure Areas




Moisture and/or alkalinity in the substrate
Improper use of patch or leveling compound
Installation of flooring and adhesive over poorly
prepared subfloor
Improper training for floor installer in a healthcare
environment
7
Moisture and Alkalinity Awareness
Moisture, and its
rate of movement
through a substrate,
is a critical factor in
the success or
failure a flooring
project.
8
Moisture and Alkalinity Awareness
One obvious result of
excessive moisture is
the failure of an adhesive
to bond the flooring to
the substrate.
9
Moisture and Alkalinity Awareness
When excess moisture
migrates through the slab,
it can carry excess salts to
the surface. Excess
alkalinity can crystallize
creating an extreme bond
breaker.
10
Moisture and Alkalinity Awareness
Mold and bacteria
issues can arise from
excessive moisture.
11
Improper Patch or Leveling
 Inadequate drying time allotted
 Applied too thick
 Wrong primer for type of substrate
 Gypsum product used on or below grade
12
Improper Floor Preparation
 Low spots filled with adhesive, causing flooring to
indent
 Patch is used instead of underlayment board
 Flatness tolerance is not achieved prior to floor
installation
 Substrate is not checked for flatness
 Installed failed to detect surface imperfections prior
to installing floor covering
13
Why Do Floors Fail?
85% of all healthcare
flooring installations
fail due to improper
subfloor preparation
14
Jobsite Preparation
Substrate is
examined
for high spots or low
areas
15
Concrete Subfloor Prep
Considerations:






Floor should be smooth, clean, dry
Floor should be free of ALL contaminants
Examine for construction joints or saw cuts
Check expansion joints
Achieve flatness tolerance levels
Use proper leveling products
16
Wood Underlayments
 Wood underlayments are used when the
condition of the substrate is not acceptable
 It is used to provide a dimensionally stable,
smooth surface to receive the new floor
covering
Failures arise from:
 Wood not structurally sound
 Inadequate fastening of wooden subfloor
 Use of poor quality lauan resulting in staining

Conditions Impacting Adhesion and Contributing
to Contaminant Transference:
Dusting…Scaling…Flaking…Pop-outs...Delamination…Cracking…and of
course: Moisture & Alkalinity
Recognize Presence of Contaminants
Dust…Cure & Seal…Acid…Machine Oil…Micro-fractures
Determine Appropriate Preparation Methods & Equipment
Abrasive-blasting…Scarifying…Bush-hammering…Hydro-blasting

One Goal
Deliver a workforce of floor covering
professionals who understand how to
protect the patients and staff during a
building project, while not disturbing
daily activities.

Working Together
Healthcare facility managers who understand the procedures
involved in construction-related infection control can help to
reduce the risks…
Architects who understand the specific risks involved can
help communicate the facility’s needs to the contractor….
Contractors and workers who understand the issues involved
when working in a healthcare facility help to add value,
safety and professionalism to healthcare construction
projects.
