Waterstops Sample Clauses
Waterstops. Waterstops shall be of approved manufacture and of the pattern and the material and widths scheduled and specified and shown on the drawings. They shall comply with the tolerances specified in clause 6.1 of SABS 1200GThe waterstops shall conform to the Specifications as set out in CKS 388 for Rubber Waterstops and shall have the appropriate physical properties as set out below: Form Black Rubber Hydrostatic Head Up to 50m Tensile strength >20.7 MPa Elongation at break 500% Hardness BS degrees (IRHD) 62 to 72° All intersections between waterstops shall be pre-fabricated in the factory in accordance with the manufacturer's instructions and to approval of the Engineer. Only straight lengths of waterstop may be field-welded using the appropriate jigs and tools. Where required, waterstops shall have eyelets so that they may be tied securely to the adjacent reinforcement. Waterstops shall be centre bulb unless specified otherwise elsewhere.
Waterstops. Install in construction joints and at other joints indicated according to manufacturer's written instructions.
Waterstops. A. All flashings shall be installed concurrently with the roof membrane in order to achieve a watertight condition as the work progresses. When a situation arises where a break in the day's work occurs in the central area of a roof, a temporary waterstop shall be constructed to provide a one hundred percent (100%) watertight seal, utilizing a raised temporary waterstop. Sweep back and totally clean the existing roof and set a two-inch by four-inch (2" x 4") stud atop the prepared area in roof cement as recommended by the membrane manufacturer. Where stopping work on the new system, maintain the stagger of the insulation joints by installing partial fillers.
B. Carry the new membrane up and over two-inch by four-inch (2" x 4") waterstop. Seal the edge of the membrane in a continuous heavy application of roof cement. Weight the membrane down in the sealant with a two-inch by ten-inch (2” x 10”) wood member with ballast on top. Ballast should be approximately twenty pounds per linear foot (20 lbs./l.f.). When restarting work, remove all sealant, membrane, insulation fillers, etc. from the work area. Do not reuse any of the material in the new work. Cut off contaminated PVC membrane and dispose of immediately. If inclement weather occurs while a temporary waterstop is in place, the Contractor shall provide the labor necessary to monitor the situation to maintain a watertight condition. Do not impede drainage when installing waterstops.
Waterstops. 1. Rework or replace concrete where waterstop has moved unacceptably.
2. Support water stop in exact position, do not sink water stops in fresh concrete.
Waterstops. Flexible Rubber Waterstops: CE CRD-C 513, non tapered for embedding in concrete to prevent passage of fluids through joints. Factory fabricate corners, intersections, and directional changes. Profile and dimensions as indicated.
