8−85811.04 METHOD OF MEASUREMENT.
811.04.1 Weep Holes and Pavement Subdrains. Unless covered by a Special Provision,
together with a corresponding Proposal Item, weep holes and pavement subdrains will not be measured separately for payment. 811.04.2 Wall Drains. "Wall Drains" will be measured by the number of linear feet actually installed in accordance with the Plans and/or as directed by the Engineer. 811.05 BASIS OF PAYMENT.
811.05.1 Weep Holes and Pavement Subdrains. Unless covered by a specific Proposal Item,
materials for the installation of weep holes and pavement subdrains will not be paid for separately, but will be included as incidental items in the respective contract unit prices per cubic yard as listed in the Proposal for the applicable classes of Portland cement concrete. 811.05.2 Wall Drains. The accepted quantity of "Wall Drains" will be paid for at the contract unit price per linear foot as listed in the Proposal. The price so-stated constitutes full and complete compensation for all labor, materials, and equipment, including fittings and filter stone, filter fabric, and all incidentals required to finish the work, complete and accepted by the Engineer.
812.01 DESCRIPTION. This work consists of the furnishing and installation of waterstops in
various types of concrete joints at the locations shown on the Plans or as directed by the Engineer, all in accordance with these Specifications. 812.02 MATERIALS. Polyvinyl Chloride (PVC) Waterstops. PVC waterstops shall be manufactured by the extrusion process from an elastomeric plastic compound, the basic resin of which shall be PVC. The compound shall contain any additional resins, plasticizers, stabilizers, or other materials needed to assure that, when the material is com pounded, it will meet the performance requirements given in the table below. No reclaimed PVC or other material shall be used. The PVC material shall comply with the fo llowing physical require ments when tested under the indicated ASTM test method. 8−86 Specific Gravity ASTM D792 Max 1.35 Durometer Hardness ASTM D2240 75 +/- 5 Tensile Strength ASTM D412 Min 1.8 ksi Elongation ASTM D412 Min 350% Cold Brittleness ASTM D746 -35° F Stiffness in Flexure ASTM D747 Min 0.350 ksi
812.03 CONSTRUCTION METHODS. Waterstops shall be installed at locations indicated on the
Plans. Where movement at the joint is provided for, the waterstop shall be capable of accommodating such movement without injury. Wa terstops shall be spliced, welded or soldered to form durable continuous watertight joints. Precautions shall be taken so that the waterstops shall be neither displaced nor damaged by construction operations or other means. Damaged components shall be repaired to the satisfaction of the Engineer at no additional cost to the State. All surfaces of the waterstops shall be kept free from oil, grease, dried mortar, or any other foreign matter while the waterstop is being embedded in concrete. Means shall be used to ensure that all portions of the waterstop designed for embedment shall be tightly enclosed by dense concrete per the manufacturer’s recommendations. A Certificate of Analysis from an approved independent test ing laboratory shall be provided to the Engineer. The certificate shall state that the material furnished conforms without exception to all the requirements specified herein; and shall also include all qualitative and quantitative test results.
a.Waterstops. A manufacturer requesting approval of a waterstop shall furnish to the Engineer a 3-foot length of each type of PVC waterstop he intends to supply for approval.
b.Installation of Waterstops . The Contractor shall demonstrate proven ability and competence in the installation of these products, in conformance with the manufacturer's printed instructions. If any part of this work is found defective at any time before the final acceptance, the Contractor, at his own expense, shall correct each defect to the satisfaction of the Engineer.
1.Preparatory Work . All waterstops shall be protected from oil, dirt, concrete spatter, damage, and shall be clean to receive concrete forms. Particular care shall be taken during installation of waterstops to eliminate all deficiencies that may cause leakage. Waterstops shall be positioned so as not to create interference with reinforcing bars and slip during installation.
2.Methods . Different methods may be used to fasten the waterstop in position. All waterstops shall be held rigidly in place by extending through slots in keyways; held by split bulkheads; tied to reinforcing bars; or other adequate methods as necessary to ensure proper support and embedment during the concreting proce ss. The method used shall not cause damage to the waterstops or in any way compromise the integrity of the watertight seal.
3.Splicing . PVC waterstops may be butt-spliced on the job in accordance with the manufacturer’s recommendations. The Contractor shall demonstrate to the Engineer that all persons who are responsible for performing splices are capable of creating the proper joint. Upon request the manufacturer shall demonstrate the splic ing method for producing a strong, water-tight
