FOR MANHOLE REHABILITATION

Printable version for Manhole Rehabilitation Specifications

(1) Intent and Method of Manhole Rehabilitation. Each indicated concrete or brick structure shall be rehabilitated to eliminate infiltration and exfiltration, restore structural integrity and protect the structure from further deterioration. All products to be used in the rehabilitation system shall be supplied by a single supplier to insure material compatibility. Contractors bidding on the rehabilitation project(s) must demonstrate that they are qualified by experience and must be trained and licensed to apply the specified products.

(2) Materials: The materials used shall be designed, manufactured, and intended for manhole and sewer structure rehabilitation and the specific application in which they are used. The materials shall be delivered to the job site in original unopened packages and clearly labeled with the manufacturer's identification and printed instructions. All material shall be stored and handled in accordance with recommendation of the manufacturer and the American Concrete Institute.

(3) Execution: Manholes requiring rehabilitation are listed or tabulated in the contract documents. The list will identify and locate the manholes to be rehabilitated and the type of rehabilitation required for each manhole.

     (3.1) Surface Preparation shall consist of water blasting (minimum 3500 psi) the interior of the manhole or structure in order to accomplish the removal of loose mortar, paints, protective coatings, efflorescence, all contaminants, laitance and curing components, leaving a clean, structurally sound substrate. Wire brushing or sand blasting may be required.

     (3.2) Hydrostatic Leak Correction. All active leaks shall be stopped using one of the following products. Please refer to product sheets or contact manufacturer to assist with product selection.
