Cut down high spots and fill all low spots. Uniformly slope surfaces to drains. Immediately after leveling, refloat the surface to a uniform, smooth, granular texture.

2. After floating, begin the first trowel finish operation using a trowel. Begin final troweling when the surface produces a ringing sound as the trowel is moved over the surface.

3. Consolidate the concrete surface by the final hand troweling operation. Finish shall be free of trowel marks, uniform in texture and appearance, and with a surface plane tolerance not exceeding c inch in 10 feet when tested with a 10 foot straight edge. Grind smooth surface defects.

tested for leaks by the Contractor with clean water prior to surface coating or painting. Leaks shall be repaired by the Contractor. The procedure and manner in which leaks are repaired shall meet the approval of the Engineer. All costs associated with the testing and repair of leaks shall be at the expense of the Contractor. Prior to beginning of the leakage test, the structure shall be filled to the highest working water level and allowed to stand for a period of 24 hours to allow for absorption.

B. Leakage limitations shall be as follows: C. All water visibly flowing through a concrete wall shall constitute a leak and shall be repaired by

pumping and sealing the crack with a NSF-approved for potable water contact material. D. Damp areas not exceeding one percent of the total wall wetted area and not having visible

seepage shall be conditionally acceptable subject to all said dampness being eliminated by application of the water side surface treatment as may be specified. In the absence of a specified water side surface treatment or where said treatment does not eliminate wall dampness, the water side of the wall shall be prepared in accordance with the manufacturer's instructions and a NSF approved for potable water contact epoxy concrete surface coating applied.

E. All leakage testing shall be performed prior to backfill. F. To check for leakage through the tank bottoms, the fall in surface water level during tank testing

shall be measured and shall not exceed 0.5 inch in a 24 hour period, providing allowance for evaporation at a rate approved by the Engineer. Visual leaks, either flowing or damp areas, observed during the filling, absorption, or test periods shall be marked and locations recorded and repaired.
