3.14 CONCRETE SURFACE REPAIRS***THIS ARTICLE PROVICES BASIC APPLICATIONS FOR REPAIRING CONCRETE SURFACES. REVISE OR DELETE TO SUIT THE PROJECT***A. Defective Concrete: Repair and patch defective areas when approved by the Project

Manager. Remove and replace concrete that cannot be repaired and patched to the Project Manager's approval.



B. Patching Mortar: Mix dry-pack patching mortar, consisting of one-part portland cement to two and one-half parts fine aggregate passing a Number sixteen (#16) sieve, using only enough water for handling and placing. Achieve approval of the Project Manager prior to any patching as to location of patches and patch material.

C. Patch Testing: On a portion of the work which will, in the finished condition, be concealed, test patch materials and methods and obtain the Project Manager’s approval prior to patching concrete surfaces needing repair that will be visible in the final construction.

D. Repairing Formed Surfaces: Surface defects include color and texture irregularities, cracks, spalls, air bubbles, honeycombs, rock pockets, fins and other projections on the surface, and stains and other discolorations that cannot be removed by cleaning.1. Immediately after form removal, cut out honeycombs, rock pockets, and voids

more than one half inch (1/2”) in any dimension to solid concrete. Limit cut depth to three quarter inches (3/4”). Make edges of cuts perpendicular to concrete surface. Clean, dampen with water, and brush-coat holes and voids with bonding agent. Fill and compact with patching mortar before bonding agent has dried. Fill form-tie voids with patching mortar or cone plugs secured in place with bonding agent.

2. Repair defects on surfaces exposed to view by blending white portland cement and standard portland cement so that, when dry, patching mortar will match surrounding color and texture. Patch a test area at inconspicuous locations to verify mixture and color match before proceeding with patching. Compact mortar in place and strike off slightly higher than surrounding surface.

3. Repair defects on concealed formed surfaces that affect concrete's durability and structural performance as determined by the Project Manager.

E. Repairing Unformed Surfaces: Test unformed surfaces, such tops of walls, for finish and verify surface tolerances specified for each surface. Correct low and high areas. Test surfaces sloped for trueness of slope and smoothness; use a sloped template.1. After obtaining approval of the Project Manager, repair finished surfaces

containing defects. Surface defects include spalls, popouts, honeycombs, rock pockets, crazing and cracks more than one-one hundredths inch (0.01”) wide or that penetrate to reinforcement or completely through unreinforced sections regardless of width, and other objectionable conditions.a. If, after repairs are complete, the Project Manager deems the repairs did

not successfully correct the original deficiencies, the pavement or concrete element in question is to be removed and replaced per Subsection 3.13. E.1. above.

2. After concrete has cured at least fourteen (14) days, test for low and high spots in finished surface. Areas that do not conform to the tolerances set forth in Division 32 and in other reference standards identified in this specification are to be sawcut to the nearest joint as approved by the Project Manager, defective concrete removed, and new conforming paving reinstalled. Color and finish is to match adjacent concrete.

3. If approved by the Project Manager, repair random cracks and single holes one inch (1”) or less in diameter with patching mortar. Groove top of cracks and cut out holes to sound concrete and clean off dust, dirt, and loose particles. Dampen cleaned concrete surfaces and apply bonding agent. Place patching mortar before


Updated: January 2021bonding agent has dried. Compact patching mortar and finish to match adjacent concrete. Keep patched area continuously moist for at least seventy-two (72) hours.

F. Perform structural repairs of concrete, subject to the Project Manager’s approval, using epoxy adhesive and patching mortar.

G. Repair materials and installation not specified above may be used, subject to Project Manager approval.

A. Maintenance Period: The maintenance period shall commence from the date of Substantial Completion on an existing Contract, or a start date established by a separate maintenance contract in accordance with these Specifications. The Maintenance Period shall continue for [two (2), three (3)] years.


3.2 NATIVE SEEDING AREAS

E. Watering: All watering shall be done in such a way as to encourage establishment, deep root growth and drought tolerance. [Choose one of three]

1. [Watering: Utilize irrigation system to water native seeded areas to obtain establishment of an acceptable grass stand, and to supplement natural moisture levels during dry periods.]a. [Schedule watering to prevent wilting, puddling, erosion, and displacement of

seed or mulch. Lay out temporary watering system to avoid walking over muddy or newly planted areas. Obtain approval of Project Manager of irrigation system and schedule proposed for use.]

b. [Water native grasses with fine spray at a minimum rate of one-half inch (1/2”) per week for six (6) weeks after planting unless rainfall precipitation is adequate.]

c. [Do not over-water in a manner which kills drought-tolerant components of the seed mix.]

2. [Watering: Install and maintain temporary piping, hoses, and watering equipment to convey water from sources and to keep soil uniformly moist.]a. [Schedule watering to prevent wilting, puddling, erosion, and displacement of

seed or mulch. Lay out temporary watering system to avoid walking over muddy or newly planted areas. Obtain approval of Project Manager of irrigation system and schedule proposed for use.]

b. [Water native grasses with fine spray at a minimum rate of one-half inch (1/2”) per week for six (6) weeks after planting unless rainfall precipitation is adequate.]

c. [Do not over-water in a manner which kills drought-tolerant components of the seed mix.]

3. [Watering: Utilize watering trucks to supplement natural moisture levels during dry periods.]a. [Apply water in a manner that prevents wilting, puddling, erosion, and

displacement of seed or mulch. Obtain approval of Project Manager of truck/application type and schedule proposed for use.]


Updated: January 2021b. [Do not over-water in a manner which kills drought-tolerant components of

the seed mix.]c. [This frequency and rate of irrigation is to be approved by the Project

Manager. Contractor will be paid through a separately negotiated Change Order for this work.]

F. Mowing:

1. Year One: Mowing of native grasses in the first year after seeding should be avoided. If a mowing of native grasses is required obtain the

approval from the City Naturalist and Project Manager prior to mowing. If mowing in the first year is allowed, then mow only in the early growing season or late in the fall to allow grass seeds to drop. Mowing shall be at a height of six inches (6”) to eight inches (8”).

2. Year Two: Mow native grasses in the early spring or late fall to allow desirable grass seeds to drop. Mowing shall be at a height of six inches

(6”) to eight inches (8”). Control undesirable plant species as necessary by mowing, hand-pulling, selective pesticide application, and/or prescribed burning. 3. [Year Three: Mow native grasses in the early spring or late fall to

allow desirable grass seeds to drop. Mowing shall be at a height of six inches (6”) to eight inches (8”). Control undesirable plant

species as necessary by mowing, hand-pulling, selective pesticide application, and/or prescribed burning.]
