2 Deck Overlay Boards

Two layers of gypsum board shall be installed over steel decks as an acceptable substrate for adhered waterproofing membranes when cast in place concrete topping is not present. The first layer of gypsum or cement board shall be either be fully mechanically fastened to the deck or adhered to the deck with manufacturer's approved compatible polyurethane adhesive. The second board layer must be adhered with a compatible manufacturer's approved polyurethane adhesive.

3 Membranes

RGC specifically accepted waterproofing membrane systems listed in the Accepted Materials of this Manual include the following:

• Two Ply SBS Modified Bituminous Membranes
• Butyl Elastomeric Single Ply Membranes (NOTE: Currently, there are no butyl membranes accepted for use in the RoofStar Guarantee Program)
• Poly Vinyl Chloride (PVC) Plastomeric Single Ply Membranes
• Hot Fluid - Applied, Rubberized Asphalt Systems.

Only waterproofing membrane systems that are fully adhered and have an accepted protection layer installed above the membrane (protected) qualifies for coverage under the RoofStar Guarantee Program.

All waterproofing system accessory components must be supplied or be accepted for use by the membrane manufacturer.

Modified Bituminous (SBS) Membranes

SBS (Styrene Butadiene Styrene) Modified Bituminous sheet waterproofing is prefabricated elastomeric membranes that are reinforced with mats consisting of polyester, fibreglass or a combination of both reinforcement types. SBS modified bituminous membranes are available in varied thicknesses with specific physical properties to satisfy the demands of particual waterproofing conditions as well as surface finishes that facilitate various application methods.

Composition

Bituminous and modified bituminous flexible membrane systems are composite sheet membranes which are thermoplastic in nature but display variable elastomeric properties when modified. These sheets generally consist of bitumen (oxidized or modified), reinforcement, and surfacing materials. The performance of these membranes may be compromised by subtle, seemingly inconsequential changes in composition.

The formulation of the bitumen is critical, particularly when its physical properties are modified by the addition of polymers. Bitumen is most commonly modified with styrene butadiene styrene (SBS). The manufacturer must ensure that a suitable degree of compatibility exists between the bitumen and the polymer and that a thorough mix has been obtained. The careful selection and combination of bitumen and polymer (the type of modifier, the percentage of polymer used, etc.) determines the physical properties and long term performance of the modified bituminous "binder". The binder provides the membrane with its waterproofing capability and may impart the following properties:

• low temperature flexibility
• elasticity
• high temperature resistance to flow
• resistance to aging

The bitumen utilized for oxidized bituminous membranes has been "blown", similar to roofing asphalt. This produces a higher softening point and, therefore, a more useful temperature range.

The physical properties of the binder are further enhanced by the imposition by saturation or coating onto a carrier or reinforcing mat, most commonly a textile such as:

• non-woven spun-bonded polyester
• woven polyester scrim
• fibreglass mats
• woven fibreglass cloth
• combinations of the above.

Thermoset Membranes (PVC)

Thermoplastic materials are defined as polymers which soften when heated and harden when cooled. This process is repetitive provided the material is not heated above the point at which decomposition occurs. No cross-linking or vulcanization occurs. In addition to heat welding, some materials can be solvent welded. These welds develop bonding strengths equalling or surpassing the strength of the base materials. Thermoplastic membrane systems that comply RGC Guarantee Standards, are installed as fully adhered protected waterproofing assembly, qualify for coverage under the RoofStar Guarantee Program.

Composition

Thermoplastic materials used for waterproofing decks on plazas, promenades and terraces in the RoofStar Guarantee Program include only PVC (Polyvinyl Chloride) Membranes:

PVC is a thermoplastic material produced through the polymerization of vinyl chloride, resulting in a relatively hard, resinous material. This material is then formulated with compounds, such as plasticizers and stabilizers, depending on the physical properties required for end use. PVC formulations have been developed to suit numerous commercial and industrial applications.

PVC waterproofing systems are single-ply membranes reinforced with polyester fabric or glass fibres, and in thicknesses usually ranging from 1.2 mm to 2.0 mm, depending on the manufacturer. The membrane is fully adhered and Seams are heat or chemically welded (see manufacturer's requirements).

PVC membrane should conform to CGSB 37-GP-54M 1979, "Roofing and Waterproofing Membrane, Sheet Applied, Flexible, Polyvinyl Chloride" which lists two types of membrane, according to manufacture:

• Type 2 - reinforced

and four classes, according to end use::* Class A - non-exposed roofing

• Class B - exposed roofing
• Class C - waterproofing
• Class D - flashing membrane asphalt compatible

This standard covers requirements such as "thickness, lap joint strength, permeability, tensile strength, elongation at break, low temperature flexibility, water absorption, resistance to accelerated weathering, dimensional change after stress relaxation, and cone penetration"

PVC membranes should be applied in conformance with CGSB 37-GP-55M 1979, "Application of Sheet Applied Flexible Polyvinyl Chloride Roof Membrane" and the membrane manufacturer's printed instructions.

4 Membrane Protection Boards

A RoofStar-accepted membrane protection layer (asphalt core board, cap sheet or protection mat), must be installed by the waterproofing contractor, and be compatible with waterproofing membrane. The protection layer shall be installed and secured, as soon as possible, upon completion of waterproofing membrane installation. Construction traffic, by other than waterproofing trade and membrane moisture monitor technicians, is not permitted until the membrane protection layer is completely installed and secured.

6 Membrane Moisture Surveys & Monitoring Sensor Grids

A membrane moisture scan survey and report that confirms the water tight integrity of waterproofing systems is a mandatory requirement of the RoofStar Guarantee Program for all waterproofing systems, prior to installation of overburdens or wearing courses. Membrane moisture survey scans must be performed by an independent moisture detection company, whose moisture detection system has been reviewed by the RCABC Technical Committee and deemed to be suitable for inclusion in the RoofStar Guarantee Program (Waterproofing). In addition, moisture monitoring sensor grids (conductance scanning grid) are mandatory and shall be installed on the top surface of all waterproofing membrane systems designed with inaccessible overburdens and wearing courses. The exceptions that do not require moisture monitoring sensor grids are pavers on pedestals and gravel ballast to a maximum 100mm (4") thick . Moisture monitoring sensor grids shall be installed prior to installation of overburdens or wearing courses and may be placed over protection boards or SBS membranes that have been set in hot fluid-applied modified asphalt.

Note:

Flood Testing is not a recommended practice but is at the discretion of the design authority or owner. If flood testing is required to water test waterproofing membranes, testing shall be conducted prior to installation of insulation and overburdens and be performed to ASTM D5957 - 98.
