MANUFACTURE
Alkorplan Roof Waterproof Membranes are
manufactured by calendering plasticized PVC
into sheets. Two or three of these sheets are then
heat laminated together with a reinforcing scrim
in between or fleece-backed if appropriate. The
product is then cut to length and reeled onto a
cardboard core, wrapped and labelled.
DELIVERY, STORAGE AND MARKING
Each roll carries a label bearing the product’s
name, product description including type no.,
article no., thickness, width and length. The same
product description as before and in addition the
batch no. and the date of production are printed
on the top side of the edge of the roofing sheet at
regular spaces. Labels containing the IAB
identification mark and IAB Certificate number
are fixed to each roll pack.
Rolls are to be stored horizontally on pallets in a
dry condition. No more than two pallets should be
stored on top of each other.
Solvents and sealants must be stored in a dry,
sealed area reserved for inflammable materials.
2.6
INSTALLATION
Only trained installers, working in accordance
with the manufacturer’s recommendations and
manufacturer’s installation instructions shall carry
out installation of the roof covering.
Roof decks to which the covering is applied, must
comply with BS 6229:2003 Code of practice for
flat roofs with continuously supported coverings.
Substrates should be clean and free from sharp
projections such as nail heads and concrete nibs.
Where Alkorplan Roof Waterproof Membranes
are laid over rough finished decks, the
appropriate protection layer must be used.
The roofing sheets are not compatible with
bitumen, coal tar pitch or oil based products and
direct contact with such products must be
prevented by use of one of the recommended
separating layers.
Direct contact with polystyrene, polyurethane or
polyisocyanurate insulation boards can only be
used under Alkorplan when they have a top
surface of laminated aluminium foil or have one
of the recommended separating layers
intervening.
Alkorplan Roof Waterproof Membranes may be
laid in conditions normal to roofing work, but
should not be laid in wet weather conditions. At
temperatures below 5oC, to avoid the risk of
moisture entrapment or contamination of the
solvent used in lap jointing, suitable precautions
must be taken.
All installation work must be carried out under the
supervision of operatives who have received
training from Renolit Belgium NV.
2.6.1 Installation Procedure: Mechanically Fixed
System
Alkorplan Roof Waterproof Membranes must be
initially loose-laid with the light grey/coloured
surface uppermost (automatically when unrolling
the roll). The loose-laid waterproofing membrane
should be secured by mechanical fixing using the
appropriate roof fasteners for each kind of
supporting substructure (SFS Isofast pressure
plates or equal). The lap joints are made using
solvent by hot air welding. Laps must be at least
100mm wide and shall be fully supported during
welding operations as to accommodate the
pressure plate of the fixing element and a 50mm
wide weld (see Figure 1).
The mechanical fixing of the initially loose-laid
membrane is designed to absorb the wind uplift
forces and to transmit these forces to the
supporting substructure. The fixing system
described in Section 2.1 of this Certificate is to be
used.
Where SFS discs or equal are used, the
Alkorplan Roof Waterproof Membrane is fixed in
the joint overlaps. The discs are installed with the
longitudinal side parallel to the outer edge of the
membrane and with a minimum dimension of
30mm from the edge to the centre of the disc.
The overall overlap width in the membrane must
be 100mm, in order to ensure a remaining
overlap width of 50mm to accommodate the weld.
Certificate No. 03/0192 / Alkorplan Roof Waterproof Membranes
The fixing in the supporting substructure is
effected by corrosion resistant screws.
The pressure plates of the fixing elements are
installed in the overlap with the longitudinal side
parallel to the outer edge of the membrane and
with a minimum dimension of 30mm from the
edge of the sheet to the centre of the pressure
plate. The pressure plates are fixed to the
substrate by means of corrosion resistant screws
through the thermal insulation, vapour control
layer and existing protection or separation layers
to the supporting substructure.
2.6.2 Installation Procedure: Ballasted System
Alkorplan Roof Waterproof Membranes must be
loose laid with the light grey surface uppermost.
The loose-laid membrane should be secured by
ballast. The lap joints are made using solvent or
by hot air welding. Laps must be at least 50mm
wide (see Figure 2). The ballast on the initially
loose-laid membrane is designed to absorb the
wind uplift forces and to transmit these forces to
the supporting substructure. Immediately after the
installation of the Alkorplan membrane on the
surface, a sufficient layer of ballast is put in place
to avoid movement of the membrane by wind
forces. When necessary, a protection layer is
previously installed between the membrane and
the ballast.
2.6.3 Installation Procedure: Glued System
Alkorplan Roof Waterproof Membranes are glued
with Alkorplus PU adhesive to the substrate.
Appropriate substrates for gluing Alkorplan
membranes are metal, concrete or timber
supporting substructures as well as existing
bituminous waterproofing of old roofs or thermal
insulation specially designed for this purpose.
2.6.4 Details
Upstands, edge and gulley details are formed in
Alkorplan Metal (PVC coated galvanised steel)
sections mechanically fixed to the substructure.
Alkorplan Roof Waterproof Membranes should be
continuously welded to all Alkorplan Metal
components (see Figure 4).
2.6.5 Jointing Procedure
The solvent used in welding laps has a low flash
point and where it is to be used in enclosed
spaces, adequate ventilation facilities should be
provided.
Welds must be achieved using Alkorplan solvent
or by means of a hot air welder. The lap joint area
on both sheets must be cleaned back a minimum
of 50mm and then dried. Laps must be at least
50mm wide and should be fully supported during
welding operations.
Welded laps should be consolidated by the
application of firm even pressure to ensure a
watertight seal. All laps must be checked at least
15 minutes after welding by running a metal
probe along the welded edge, and any
discontinuities made good.
All laps must finally have a bead of Alkorplan
liquid PVC sealing mastic applied to the exposed
edge and injected into any voids to close all
remaining capillaries. Hot air welding may also be
used to close capillaries.
The lap joints are made by solvent or hot air
welding. Laps must be at least 80mm wide. The
weld is 50mm wide (see Figure 3). The glue is
designed to absorb the wind uplift forces and to
transmit these forces to the supporting structure.
The PU adhesive is applied in stripes and spread
on full area.

4.2
CONDENSATION RISK
When a vapour barrier is used on the warm side
of the insulation, interstitial condensation will not
occur within the system.
4.3
MAINTENANCE
Alkorplan Roof Waterproof Membranes have little
need of maintenance. Drainage outlets and
gutters should be regularly maintained.
4
4.4
WEATHERTIGHTNESS
Test data examined by the IAB confirm that
membranes, and joints in membranes, when
completely sealed and consolidated, will
adequately resist the passage of moisture to the
inside of the building and so meet the
requirements of Part C of the Building
Regulations 1997 to 2006.
The membranes are impervious to water and
when used in the systems described will give a
weather tight roof covering capable of accepting
structural movements without damage.
4.5
DURABILITY
When installed in accordance with this Certificate
and adequately supported by the substrate, the
system’s life as a weatherproof covering will be in
excess of 30 years and the need for maintenance
will be minimal. Repairs can be carried out by the
procedures listed above and are effective in
restoring weather tightness.
4.6
TOXICITY
The membranes are not toxic in normal service.
4.7
SECURITY OF FIXING
Properly mechanically fixed, ballasted or bonded
membranes are capable of resisting wind loads.
Membranes, being flexible, have good resistance
to cyclic movement.
4.8
APPEARANCE/STAINING
Water running off the membranes does not stain
walls.
4.9
EFFECTS OF TEMPERATURE
Alkorplan Roof Waterproof Membranes will resist
temperatures in the range of –20oC to 80oC.
4.10
