1. Weld the back edge of the seam with a narrow but continuous weld to prevent loss of hot air during the final welding.
2. Insert the nozzle into the seam at a 45degree angle to the edge of the membrane. Once the proper welding temperature has
been reached and the membrane begins to "flow," the hand roller is positioned perpendicular to the nozzle and rolled lightly. For
straight seams, the 1-1/2 inch wide nozzle is recommended for use. For corners and compound connections, use the 3/4 inch wide
nozzle.
C. Machine Welding
1. Machine welded seams are achieved by the use of Sika Sarnafil's automatic welding equipment. When using this equipment,
follow Sika Sarnafil's instructions and local codes for electric supply, grounding and over current protection observed. Dedicated
circuit house power or a dedicated portable generator is recommended. Use no other equipment simultaneously off the generator.
2. Metal tracks may be used over the deck membrane and under the machine welder to minimize or eliminate wrinkles.
D. Quality Control of Welded Seams
1. Check all welded seams for continuity using a rounded screwdriver. Visible evidence that welding is proceeding correctly is
smoke during the welding operation, shiny membrane surfaces, and an uninterrupted flow of dark grey material from the underside of
the top membrane. On-site evaluation of welded seams shall be made daily by the Applicator at locations as directed by the Owner's
Representative or Manufacturer's representative. Take one inch wide cross-section samples of welded seams at least three times a
day. Correct welds display failure from shearing of the membrane prior to separation of the weld. Patch each test cut by the
Applicator at no extra cost to the Owner.
3.07 MEMBRANE FLASHINGS
Install all flashings concurrently with the roof membrane as the job progresses. No allowance for temporary flashings without the prior
written approval of the Owner's Representative and Manufacturer. Only specific locations on specific dates will be approved. If any
water is allowed to enter under the newly completed roofing, remove and replace the affected area at the Applicator's expense. Adhere
flashing to compatible, dry, smooth, and solvent-resistant surfaces. Use caution to ensure adhesive fumes are not drawn into the
building.
A. Adhesive for Membrane Flashings
1. Over the properly installed and prepared flashing substrate, apply adhesive according to instructions found on the Product Data
Sheet. Apply the adhesive in smooth, even coats with no gaps, globs or similar inconsistencies. Flash only an area which can be
completely covered in the same day's operations. Firmly press the bonded sheet in place with a hand roller.
2. Apply no adhesive in seam areas that are to be welded. Apply all panels of membrane in the same manner, overlapping the
edges of the panels as required by welding techniques.
B. Install stop according to the Detail Drawings with approved fasteners into the structural deck at the base of parapets, walls and curbs.
C. Follow Manufacturer's requirements, recommendations and the specifications. Accept all material submittals prior to installation.
D. Extend all flashings a minimum of 8 inches above roofing level unless otherwise accepted by the Owner's Representative and
Manufacturer's Technical Department.
E. Consistently adhere all flashing membranes to substrates. Cut and hot-air weld into place all interior and exterior corners and miters.
No contact with bitumen and the membrane.
F. Mechanically fasten all flashing membranes along the counter-flashed top edge with stop at 6-8 inches on center.
G. Terminate flashings according to Manufacturer's recommended details.
H. Add additional securement to all flashings that exceed 30 inches in height. Consult Manufacturer's Technical Department for
securement method
3.08 TEMPORARY CUT-OFF
Install all flashings concurrently with the roof membrane in order to maintain a watertight condition as the work progresses. Construct all
temporary waterstops to provide a 100% watertight seal. The stagger of the insulation joints will be made even by installing partial
panels of insulation. Carry the new membrane into the waterstop. Seal the waterstop to the deck and/or substrate so that water will not
be allowed to travel under the new or existing roofing. Seal the edge of the membrane in a continuous heavy application of sealant.
When work resumes, cut out the contaminated membrane. Remove all sealant, contaminated membrane, insulation fillers, etc. from the
work area and properly disposed of off site. Use none of these materials in the new work.
Provide the labor necessary to monitor and maintain a watertight condition, if inclement weather occurs while a temporary waterstop is
in place.
If any water is allowed to enter under the newly-completed roofing, remove and replace the affected area at the Applicator's expense.
3.09 COMPLETION
Prior to demobilization from the site, the work shall be reviewed by the Owner's Representative and the Applicator. All defects noted
and non-compliances with the Specifications or the recommendations of the manufacturer shall be itemized in a punch list. These
items must be corrected immediately by the Applicator to the satisfaction of the Owner's Representative and Manufacturer prior to
demobilization.
3.10 FIELD QUALITY CONTROL
Upon completion of the installation and the delivery to Manufacturer by the Applicator of a certification that all work has been done in
strict accordance with the contract specifications and Manufacturer's requirements, a Technical Representative will inspect and review
the installed roof system.
3.13 MANUFACTURER DEMONSTRATION
Provide maintenance documents and personal instruction for the facilities staff and other interested parties at a single
pre-determined mutually convenient time.
The instruction shall include the following topics:
1. Access restriction and precautions
2. Avoiding Mechanical Damage
3. Potential Contaminants and rectification
4. Cleaning
5. Emergency repairs
I. Procedures for permanent repairs and alterations
