C. All repair materials must be intended for use in municipal sewer system manhole interiors, and have a 1-year manufacturer's warranty for defects or failures.

2.02 SEALING MATERIAL: CEMENTITIOUS LINER

All chemical sealing materials used in the performance of the work specified must have the following properties and characteristics:

A. The cementitious liner must be specifically manufactured to be resistant to degradation by hydrogen sulfide (H2S) gas in wastewater environments and to seal sources of infiltration and inflow.

B. A trowel-applied and/or spray-applied version of the liner may be used.

C. Structural Epoxy lining must be able to bond to saturated-surface-dry (SSD) concrete, with moisture and relative humidity tolerances up 85% and capable to fully cure underwater.

D. The cured material must withstand submergence in water without degradation.

E. The sealant material, after curing, must be flexible as opposed to brittle.

F. In place, the sealant formation should be able to withstand freeze/thaw and wet/dry cycles without adversely affecting the seal.

SECTION 02958 – SEWER MANHOLE REHABILITATION PAGE 3 OF 6

G. A cementitious resurfacer may be used for filling voids, bugholes, static cracks, joints, or other concrete surface defects, and to provide a uniform, void-free surface for liner application.

H. Acceptable manufacturers and materials: EpoxyTecTM Series 451 CPP

Sprayliner, Epoxytec CPP Trowel-Liner, or approved equal. The Project Engineer shall determine the required liner thickness for approved equal products.

2.03 PRE-SEALING AND SURFACE PREPARATION MATERIALS FOR

CEMENTITIOUS LINER

All manhole sealing shall be done during high groundwater conditions, unless the points of leakage have been previously identified.

B. Covers shall be placed over the invert of the manhole to prevent extraneous material from entering the sewer system.

C. Do not prepare surfaces or apply sealing materials in rain, snow, fog, mist, or otherwise inclement weather as per material manufacturer’s instructions.
