Engineer prior to installation.
·
All materials and shop drawing shall
be approved by Engineers prior to any activities.
·

to start of Tile Installation.
·
All HSE Permits shall be secured ahead
of the time.
2.5.1 Material Storage and
Handling

activities, refer to the approved shop drawings related to the installation
area & ensure that materials were as per approved material submittal.
b.
Incoming material inspection must be
done with the consultant prior to installation to verify its compliance to the
approved material submittal.
c.
Waterproofing Inspection and Leak
test on wet areas shall be completed prior to start installation.
d.
MEP Clearance on all areas related to
the installation must be obtained.
e.
Tile edges will be accurately cut to
a close fit where necessary, at abutments, around electrical pipes and other openings.
f.
Movement Joints not less than 6 mm
wide are to be provided as per approved shop drawing.
g.
Corner Trim to be used to be used for
fixation.
h.
Tile adhesive shall be prepared and applied as per manufacturers

j.
The finished surface of the tiles
should be plumb and true such when checked with a 3 m straight edge no gap exceeds
3 mm.
k.
The joints shall be even,
approximately 2 mm wide and where tile without spacer lugs are used, spacer pegs
of suitable and even thickness shall be inserted between the tiles as the work
proceeds.
l.
The joints are to be grouted by
approved grouting material after the adhesive has set and not less
than 48 hrs after fixing. The grout shall be well worked into the joints so that
they are completely filled and finished flush.
m.
Excess/Surplus grout shall be cleaned
off using damped or wet cloth.
n.
Final Inspection shall be requested
for Engineers approval and acceptance.

test on wet areas shall be completed prior to start installation.
c.
Incoming material inspection must be
done with the consultant prior to installation to verify its compliance to the approved
material submittal.
d.
After casting of
required thickness of screed as per design requirements, surface shall be
suitable for floor coverings, areas to be tiled shall be cleaned and dampened
until absorption ceases and the level of the finished floor shall be
established by the surveyor.
e.
MEP Clearance on all areas related to the installation
must be obtained.
f.
Double direction horizontal layout of
tiles to be installed must be checked and approved by the Engineer prior to

g.
Tile adhesive shall be prepared and applied as per manufacturers
recommendation.
h.
The bedding mortar for tiles 10 mm
thickness or less are used in which case the bedding is not to exceed 15 mm
shall be levelled and tamped with a straight edge board.
i.

l.
Tile to be laid level or to 1% slopes
