They are
waterproofing covers
produced through the
modification of
bitumen (asphalt) by
Polymer-based
plastics, and
together with
carrying equipments.
Bitumens are
grouped as such:
1.
Penetration Bitumens
2.
Oxidized Bitumens
3.
Polymer Bitumens
Polymer Bitumens are
divided into
two as
Plastomeric
and
Elastomeric
.
Plastomeric
Bitumens
are synthetic
rubbers that are
produced through APP
modification, and
that lengthens the
life of the material
by protecting it
from the Ultraviolet
impacts.
In
this type of our
membranes that are
the ideal preference
in the temperate
zone Atactic
Polypropylene (APP)
with
thermoplastic resin
is used to increase
the resistance of
bitumen. And
fiberglass or
polyester felt is
used as carrier to
increase the
physical strength of
the membranes. It is
easy to apply by
torching and hot
asphalt.
Elastomeric
Bitumens ,
however , are
synthetic rubbers
that are produced
through SBS
modification, and
that lengthens the
life of the material
by protecting it
from the Ultraviolet
impacts.
Styrene-Butadiene-Styrene
(SBS-artificial
rubber based polymer
that has very highly
elasticity)
containing
thermoplastic resin
is used to increase
the resistance of
bitumen. This type
SBS-added membranes
that are highly
resistant to aging,
that have high
utilization
performance,
protecting its
stability in cold
climates are used in
cold climates and in
mobile buildings
desired to be highly
elastic.
SBS gives the
material a
continuous
elasticity even in
low temperatures.
And fiberglass or
polyester felt is
used as carrier to
increase the
physical strength of
the membranes.
Cracking and
breaking under cold
weather conditions
are not concerned.
It is easy to apply
by torching and hot
asphalt.
Membranes
are divided into two
according to the
carriers:
1. Membranes
with Polyester Felt
Carrier
The waterproofing
membranes that are
produced through
using spunbond felt
that weighs 150 gr/m
2 , 170 gr/m?, 180
gr/m 2 or 250 gr/m 2
are ‘ Membranes with
Polyester Felt
Carrier '.
They are available
in thicknesses such
as 2mm, 3mm, and
4mm.
2. Membranes
with Fiberglass
Carrier
The waterproofing
membranes that are
produced through
using fiberglass
that weighs 50
gr/m?, 80 gr/m 2 ,
however, are called
‘ Membranes with
Fiberglass Carrier
'.
They are available
in thicknesses such
as 2mm, 3mm, and
4mm. Both faces are
coated with
polyethylene.
Over the membranes
to be used outdoor,
natural stones –
granule-shaped
colored minerals are
laminated. This type
of membranes is
called
Slated
membrane, and only
one side is coated
with polyethylene.
Another one-side
polyethylene-coated
product is
Aluminum Folio
.
Climatic conditions
of the region where
the membrane is to
be used are
primarily important
in deciding to use
which type of
membranes.
In application,
special attention
must be given to
details and product
selection. It must
be carried out by a
professional
workers-staff
absolutely. Staff
members certified by
the producing firms
must be preferred in
application. |
