Movement Joints in Buildings & Civil Engineering StructuresbyNCC-Emsealwww.Emseal.com (CPD Accredited: 60mins)
Slide2Movement Joints in Buildings & Civil Engineering StructuresToday is intended to provide guidance on:What
Are Movement Joints & Their Demands?
Where Exactly Are
These Movement Joints
?
Major Movement Joint Problems
Learning
from the North American
Experience
The Movement Joint Checklist
Traditional Movement Joint Solutions
Innovative Practical Movement Joint Solutions
Slide3What Are Movement Joints?A ‘GAP’ in the structure or structural element to separate and accommodate movement due
to many factors
Slide4Types of Movement?Movement may be due to:Static-loadingDynamic-loading / Vibration
Thermal Movement
Wind Sway
Subsidence
Shear Forces
Seismic Events….
etc.
Usually
a Combination of Movement Factors e.g. Thermal (Heating Up
or
Cooling Down),
with Simultaneous Static
& Dynamic Loading etc
.
Slide5Joints with Complex Movement Parameters
Slide6Additional Project Based Demands for Joint Performance (in addition to movement - which can be in more than one plane & with shear forces too)Typically one or more of the following can apply:
Watertight
Fire Resistance
Thermal Insulation
Acoustic Insulation
Impact & Abrasion Resistance (Traffic etc.)
UV Light Resistance
Chemical Resistance
+
All Manner of Other
Project Specific Requirements
Slide7Where are these Movement Joints Everywhere that Movement is Required: In the Interior and Exterior Elements of a Structure
In
and/or Between Different Elements & Materials
Vertically
and
Horizontally
Throughout the
Building
Envelope
Slide8Slide9Unfortunately there are Problems with Movement Joints
Slide10Problems with Movement Joints:Leaking & Water ingress (to the structure & the interior)
Corrosion
Damage
(to
structural & reinforcing
steel)
Damage to Internal
Finishing’s
& Fittings
Damage to Stored Goods & Equipment
Increased Fire
Risk / Spread of
Fire
Loss of Thermal Insulation
Loss
of Acoustic Insulation
(
noise)
Traffic Disruption
(joint breakdown)
= Expensive
remedial works
&
the risk
of claims!
Slide11What Causes Problems with Movement Joints?Inadequate DesignInadequate InstallationInadequate Materials / Products
Inadequate Durability – Service Life
Damage & Abuse
Change of Use
Typically there
is
more
than one reason
and the
root cause
can
be complex
–
Especially
in the event of claims!
Slide12Movement Joint ProblemsIn a Recent North American SWRI Survey of Problems for Project Management Teams with
All-kinds of New & Refurbishment Works on
Building & Civil Engineering
Projects - The
Conclusion was:
“We have come to realize that our projects show
More Problems
with
Expansion
J
oint Seals
than
All Other Product Categories
Combined
-
Yet, expansion joint seals are a miniscule part of most of our projects in terms of the overall construction costs
.”
One recent estimate was that up to 95% of building defects are related to joints, despite the joints representing only around 1% of the original building costs!)

Slide13Movement Joints - Learning from the North American Experience“Well…Everything in America is Bigger……” Yes it’s True – Certainly for Movement Joint Problems!
Slide14North America has……Bigger Buildings & Bigger Civil Engineering Structures including: Bigger Offices, Schools, Hospitals, Shopping Malls, Stadiums and Airports, all with Bigger Car Parks,
plus
Bigger
Manufacturing
Facilities &
Bigger Roads &
Bridges too!
+
A
Bigger
Population with
Bigger
Cars & Trucks,
Bigger
Temperature Variations
(Hotter & Colder
, plus
Bigger
& More Frequent Seismic
Events,
such as
Earthquakes!
=
Bigger
Movement Joint
Problems &
Bigger
Damage
…..!
Slide15There is Good Advice from the SWRI:“……for owners & specifiers to work more closely with joint manufacturers &
Installers
to
p
roduce
t
rouble-free
m
ovement
j
oints……”
How
c
an
this be achieved?
Slide16Firstly - For Project Management Teams to: “..Design, Detail, Specify, Manufacture & Install their Movement Joints in 3-D..”- Yes Of Course Everyone Uses 3D Design Today - BUT How Many of us Create Project Specific Isometric Expansion Joint Layouts……….?
Slide1717
Specify
and
detail specific factory-made transitions
at
all changes
in
plane & direction of
each
joint
Specify
& detail correct watertight transitions
between
any & all dissimilar materials / systems
The Movement Joint System Suppliers should be able to provide detailed 3D CAD Drawings (
e.g. Visit the Free CAD Resource Library at
www.emseal.com
)
To Design
,
Detail
, Specify, Manufacture and Install in
3-D
using
Isometric Joint Layouts:
Slide18This Also Means Checking Complex Joint Designs are Possible & That They Can Be Made and Installed: i.e. Physically Create & Confirm Complex Joint Layouts Off-Site!In this way we can:Visualize possible issues
D
esign out any problems
D
esign to hide & conceal
D
etail for joint continuity
& complete watertightness
Agree construction process & methods (reducing RFI’s)
Ensure the joint manufacturer can produce it & train the contractors to be able to install it on site…..!
Slide19For the Project Management Teams to Work from a Defined Written Movement Joint Checklist to Ensure ALL of the Joint Requirements Are Considered.Secondly -
Slide20The EMSEAL Checklist Abc Proven Movement Joint
ChecklistFor New
& Retrofit

“Watertight

Design”
Slide21Movement Joints - The Checklist ApproachDesign in 3D for New Construction is the Norm (and increasingly including for the joints) – Here the
Checklist Approach
Eliminates Serious
Omissions &
Ensures
All
KEY CRITERIA are Considered:
BUT
we have
f
ar more
Existing
Buildings
& Civil Engineering
Structures in need of Refurbishment
3D Design is probably not feasible
in
Refurbishment
- So the
Checklist
Approach
is
even more
important
to
ensure that they are also
made
‘Watertight by Design’
Construction
Type & Structure / Joint Type & Functions / Location /
Dimensions / Movement / Substrate(s) / Exposure / Environment /Traffic – Type & Frequency / Fire Resistance / Transitions &
Terminations / Connections / Access / Service Life & Management etc., etc.
Slide22Slide23Movement Joint Technologies Available - For Smaller / Lower Movement Joints - Usually with less then 25% joint movement capability (25mm wide = +/- 3.25mm
),
max width
~30mm,
typically
non-trafficked,
used for movement
/ expansion joints between different building components & materials,
both vertically
and horizontally.
The Best Solutions
for these Joints are
Extruded Sealants (‘Mastics’):
Technologies
include:
Oil-based Butyl Rubber,
Acrylic,
Silicone, Polysulphide or
Polyurethane, plus hybrids and combinations of these and other extrudable polymers that are ‘gun-applied’ on site
- All of these
materials are
well established
and
their production, joint design and application is well covered
by National & International
Standards
such as ISO 11600,
EN 15651, and ASTM
C
920.
Slide24Technologies for Lower / Smaller Movement Jointse.g. Extruded Sealants / Mastic’s / Caulks (with ‘Backing Rods’)
Maximum joint
w
idth is usually 25 - 30mm
The correct
joint
dimensions MUST
be
formed
The correct
s
ealant
d
imensions MUST be formed:
- this
requires
a
ratio of
Width
=
Twice Depth (i.e. 2:1)

Slide25Movement Joint Technologies Available - For Wider / Higher Movement Joints (including j
oints with additional demands e.g. changes in plane or direction, exposure to traffic and/or resistance to fire, providing thermal or acoustic insulation)
However there is
no
unified standard or even consensus of approach in the UK, Europe, North America or elsewhere around the world, on how to treat and
seal wider / higher movement
/ expansion joints, which is not entirely surprising due to the widely different movement and exposure demands that they can be required to accommodate
.
The
Solutions for Wider / Higher Movement Joints are
Generally Pre-formed
Joints including
:
Compression Joint Seals
Inflated
Joint Seals
Strip
Seals
Open-celled
Foam Seals
Slide26Technologies for Wider / Higher Movement Joints:- Compression Seals
O
lder technology, now outdated & being replaced because these systems:
Suffer badly from
c
ompression-set
Poor thermal & acoustic
v
alues
Are
too
rigid to seal
substrate
irregularities
Tend
to fail
quickly in tension
As a result
Compression Seals
cannot be regarded as watertight systems
Slide27Instead of the internal webbing in compression seals, they use air to create back-pressureThere is stress on the adhesive bond-line & they fail when in tensionSuffer from compression-set
Poor thermal
&
acoustic
v
alues
The
thermoset rubber
cannot be
welded & so the transitions
must
be glued
These glues are not UV
resistant so cannot be used in exposed locations
Technologies for
Wider / Higher
Movement Joints:
- Inflated Seals (usually neoprene)
As a result Inflated Seals are
increasingly
being replaced
and
are now regarded as
outdated
technology
Slide28Technologies for Wider / Higher

But they are still the best option
for really wide vertical joints (>305mm).
