Expansion joint profiles
.Expansion joint profiles are most important products
,Expansion joint is an opening within a structure , designed to absorb thermal movements
.seismic movements and wind forcing
.The size of expansion joints in a building is usually determined by the structural engineers
.MTgroup produce a wide range of expansion joint profiles for interior and exterior applications
.We designed also insulation tapes for places with water leakage risk
We considered load bearing capacities so some profiles can be applied for heavy vehicles or cars
.depending on the gap inquired
Mtgroup covers (Multi profiles) provide simple solutions to cover interior or exterior floor
,. wall and ceiling joints
.Multi profiles have special installation that MTgroup specialties have designed
Also we designed movement control joint profiles for absorbing tile movement and commonly
.used for easy installation
Over 15 years in the business is proof that we stand behind those words . MTgroup has set an
,industry benchmark with our combination of highly skilled engineers,manufacturing processes
.and drafting designs

MOVEMENT JOINTS PROFILES
Movement joints are an integral part of any tile assembly. The various components of a tile
assembly (tile, mortar, substrate, etc.) expand and contract according to each component’s
intrinsic physical properties with changes in moisture, temperature, and loading, resulting in
Furthermore, structures that restrain overall expansion of the tile field (walls, columns, etc.)
cause stress buildup within the system. If the aforementioned movements are not
accommodated through the use of movement joints in the tile field and at restraining
structures ,the resulting stresses can cause cracking of the grout and tile and
delamination of the tile from the substrate.
Thus, movement joints are an essential component of any durable tile assembly.
MTgroup-Systems’ prefabricated movement joint profiles accommodate movement and
protect tile edges, resulting in a permanent,maintenance-free installation. The family
of MTgroup profiles prefabricated movement profiles includes a variety of shapes sizes
, and materials to suit different applications.
Application and Function
►Mortar Bed Joint Profiles – Type 1
MTgroup joint profiles (type1) are designed to Provide movement joints in tile
installations that are set in a mortar bed (e.g., ceramic tile, natural stone,
pavers, and agglomerate tile). These profile systems are placed to produce
individual fields in the assembly and feature flexible central zones to accommodate
MTgroup mortarbed joint profiles may also be inserted insaw-cut joints or wider
joints; for example,in the case of renovations.The remaining joint between the
tile and the profile must be filled completely with grout or epoxy.The side
sections of the profiles, made of rigid PVC, protect the edges of the adjacent
covering against mechanical stresses caused by industrial traffic.
However, where heavy mechanical stresses are anticipated,limitations of the
PVC as edge protection must be considered.MTgroup joint profiles (type1) is
available in three different heights and features stable serrated sidewalls made
of rigid PVC and a central movement zone made of soft PVC. The side sections
are made withenvironmentally color. Since the side sections are partially exposed
at the surface, also is intended mainly for industrial use.
►Surface Joint Profiles – Type 2
Surface joints must be placed within the tiled surface regardless of substrate
conditions. They provide stress relief from movements in the tile field due to
thermal and moisture expansion/contraction and loading.
MTgroup Systems offers a wide variety of prefabricated, maintenance-free
surface movement joint profiles, suitable for applications ranging from
residential to heavy commercial.
MTgroup joint profiles (type2) features made of aluminum, which are secured
in the mortar bond coat and provide edgeprotection for adjacent tiles.
Material Properties and Areas of Application
Anodized aluminum profiles feature an anodized layer that retains a uniform
appearance during normal use.The surface, however,is susceptible to scratching
and wear and may be damaged by grout or setting material. Therefore, these
materials must be removed immediately.Otherwise, the description regarding
aluminum applies.textured color-coated aluminum is pretreated (chromated)
aluminum that is color-coated with a polyurethane powder coat. The coating
is color-stable, UV-resistant, and suitable for exterior use.Protect the profile
against abrasion or scratching.Thermoplastic rubber inserts are highly resistant
to chemicals and can withstand chemical stresses typically encountered in tile
coverings. The insert is resistant to aging, weather, UV-rays, and ozone within
a temperature range of -76 °F (-60 °C) to 212 °F (100 °C).
Thermoplastic elastomers can be connected by welding if profiles are joined to
produce longer lengths.
MTgroup Flex Sealing Tape (named: R-seal )
For watertight expansion joint systems
MTGFlex Sealing tape ( R-seal ) is made from rubber and used for waterproofing expansion joints . Economical , easy and simple to apply ,
very flexible and elastic , so rubber memberane is ideally suited for sealing of
Also , We designed PPS Flex for bonding and joining MTGFlex tape.
