AFTER INJECTION CRACK SEALING OF INDIVIDUAL CRACKS, PERFORM WORK FOR

INJECTION CURTAIN WALL SEALING. INSTALL INJECTION PORTS AT SURACE OF

CONCRETE AND SEAL OUTSIDE (BURIED) FACE OF WALL PER THE MANUFACTURER

SPECIFICATIONS UNTIL LEAKAGE STOPS FLOWING THROUGH CRACKS AND SPALLS.

REPAIRED BY INJECTION SEALING. THIS WORK SHALL BE INCLUDED FOR PAYMENT

UNDER ITEM #0819002A - "PENETRATING SEALER PROTECTIVE COMPOUND" AND

WILL NOT BE MEASURED SEPARATELY.

2. CRACKS WHICH ARE 0.01" WIDE OR LARGER ARE TO BE REPAIRED WITH FLEXIBLE

SEE TABLE FOR MINIMUM SPLICE LENGTH.

THE BARS SHALL BE WIRED TOGETHER FOR

THE FULL LENGTH OF THE SPLICE (TYP.)

1. PRIOR TO REMOVAL OF EXISTING CONCRETE, THE CONTRACTOR SHALL PROVIDE ACCESS TO THE

ANTICIPATED WORK AREAS SO THAT THE INSPECTOR AND THE CONTRACTOR MAY TOGETHER

DETERMINE AND DELINEATE THE EXACT LIMITS AND LOCATIONS OF THE WORK. THE METHOD USED

TO DELINEATE AREAS OF CONCRETE TO BE REPAIRED SHALL NOT PERMANENTLY MARK THE

CONCRETE, LEAVE ANY RESIDUE AFTER REMOVAL, OR REQUIRE HARSH CHEMICALS TO REMOVE.

2. IF THE REMOVAL DEPTH EXCEEDS MORE THAN 1

2" BEHIND MAIN REINFORCEMENT, THE

CONTRACTOR SHALL CEASE REMOVAL OPERATIONS AND NOTIFY THE ENGINEER IMMEDIATELY.

3. REPAIR DETAILS APPLY TO SPALLED, SCALED, AND HOLLOW AREAS WHERE REQUIRED AND NOTED

ON DRAWINGS AND AS DIRECTED BY THE ENGINEER.

4. SURFACE PREPARATION, PROPORTIONING AND MIXING OF MATERIALS, APPLICATION OF

MATERIALS, AND REPAIR PROCEDURES SHALL BE IN ACCORDANCE WITH STANDARD

SPECIFICATION SECTION 6.01 "CONCRETE FOR STRUCTURES".

5. WELDED WIRE REINFORCEMENT USED IN REPAIR AREAS WILL NOT BE MEASURED FOR PAYMENT BUT

WILL BE INCLUDED IN THE COST UNDER ITEM #0601072 - "SURFACE REPAIR CONCRETE".

6. CORRODED, MISSING OR BROKEN REINFORCING STEEL SHALL BE REPLACED AND WILL BE

MEASURED FOR PAYMENT UNDER ITEM #0602000 - "DEFORMED STEEL BARS". BARS TO BE LEFT IN

PLACE THAT ARE DAMAGED BY THE CONTRACTOR SHALL BE REPLACED TO THE SATISFACTION OF

THE ENGINEER AND AT THE EXPENSE OF THE CONTRACTOR.

7. BONDING COMPOUND SHALL NOT BE USED PRIOR TO OR DURING THE PLACEMENT OF THE REPAIR

CONCRETE MATERIAL.

8. REPAIR CONCRETE MATERIAL SHALL BE CLASS PCC04483, OR APPROVED EQUAL.

9. THE SURFACE OF CONCRETE REPAIR AREAS SHALL MATCH THE SURFACE PROFILE OF EXISTING

CONCRETE SURFACES UNLESS NOTED OTHERWISE.

10. AREAS DISTURBED BY CONSTRUCTION SHALL BE RESTORED TO THEIR ORIGINAL CONDITION UNLESS

OTHERWISE NOTED OR AS DIRECTED BY THE ENGINEER AT NO ADDITIONAL COST TO CTDOT.

11. PENETRATING SEALER TO BE PAID FOR UNDER THE ITEM #0819002A - "PENETRATING SEALER

PROTECTIVE COMPOUND", SEE SPECIAL PROVISIONS.

12. IF CONCRETE COVER OVER EXISTING REINFORCING AND WELDED WIRE REINFORCEMENT IS LESS

THAN 1" PROVIDE A BUMP-OUT TO ENSURE A MINIMUM COVER OF 2" AND ADJUST THE DEPTH OF

SAW CUT TO AVOID CUTTING INTO BARS.

CULVERT REPAIR CONCRETE NOTES:

REPAIR DETAIL APPLIES TO AREAS OF REINFORCED CONCRETE WHERE THERE IS EXPOSED REINFORCING

AFTER REMOVAL OF LOOSE AND DETERIORATED CONCRETE.

1. REMOVE DETERIORATED MATERIAL TO SOUND CONCRETE LEAVING NO OFFSET OR ABRUPT

CHANGES IN CONTOUR. CONCRETE SHALL BE REMOVED TO 1" BELOW THE EXISTING

REINFORCING. REMOVAL OF SOUND CONCRETE MAY BE REQUIRED.

2. CONTRACTOR SHALL USE FIFTEEN (15) POUND HAMMERS MAXIMUM OR OTHER METHODS

ACCEPTED BY THE ENGINEER.

3. PRIOR TO APPLYING REPAIR CONCRETE MATERIAL, CLEAN EXISTING REINFORCING STEEL AND

CONCRETE (NEWLY EXPOSED) BY SANDBLASTING, SEE SPECIFICATIONS. MISSING OR

DETERIORATED REINFORCING STEEL SHALL BE REPLACED AS SHOWN IN DETAIL AND AS DIRECTED

BY THE ENGINEER.

4. AFTER SANDBLASTING AND CLEANING ALL DUST AND DEBRIS, INSTALL GALVANIC ANODES AND

WELDED WIRE REINFORCEMENT AS REQUIRED. AFTER SANDBLASTING AND BEFORE PLACING

REPAIR CONCRETE, DUST AND DEBRIS SHALL BE REMOVED COMPLETELY.

5. ENSURE THAT CONCRETE SUBSTRATE IS WETTED (SSD) BEFORE PLACING REPAIR CONCRETE.

6. FORM, WHEN APPLICABLE, AND PLACE REPAIR CONCRETE. CONCRETE FOR OVERHEAD REPAIRS

SHALL BE PUMPED INTO THE EXCAVATED SPACE, USING VENT TUBES AS NECESSARY TO ENSURE

THAT NO AIR IS TRAPPED IN THE PATCH.

7. IMMEDIATELY FOLLOWING CURING AND STRIPPING OF FORMS, THE NEWLY PLACED REPAIR

CONCRETE SURFACE WITHIN REPAIR AREAS SHALL BE HAMMER-TAPPED FOR SOUNDNESS. SOUND

PATCH AREAS SHALL RECEIVE A GROUT CLEAN-DOWN FINISH. ADJACENT AREAS SHALL NOT

RECEIVE SUCH A FINISH.

8. AFTER REPAIRS HAVE BEEN ACCEPTED, APPLY PENETRATING SEALER TO THE REPAIRED AREAS AS

WELL AS CONTIGUOUS AREAS TO THE REPAIR OR AS DIRECTED BY THE ENGINEER.

9. MINOR SPALLS AND SCALING LESS THAN 1/2" DEEP WITH NO REINFORCING EXPOSED AND WITH

SOUND CONCRETE REMAINING MAY BE SEALED WITH PENETRATING SEALER WITH NO REPAIR

REQUIRED UNLESS DIRECTED OTHERWISE BY THE ENGINEER.

CULVERT REPAIR CONCRETE PROCEDURE:

*REQUIREMENTS FOR WELDED WIRE REINFORCEMENT:

1.REQUIRED WHEN INSUFFICIENT BARS ARE AVAILABLE TO SECURE THE REPAIR CONCRETE.

A. FOR VERTICAL APPLICATIONS, REPAIR CONCRETE SHALL BE SECURED BY DEFORMED

STEEL BARS AT A 12" SPACING OR LESS, OR BY WELDED WIRE REINFORCEMENT

SECURED ON A 6" GRID BY TIE WIRES AND APPROVED ANCHORS INTO SOUND

CONCRETE.

B. FOR OVERHEAD APPLICATIONS WHERE BAR SPACING EXCEEDS 6", ADD WELDED

WIRE REINFORCEMENT SECURED TO SOUND CONCRETE AND REINFORCING ON A

6" GRID.

2.ACCEPTABLE ALTERNATIVES TO WELDED WIRE REINFORCEMENT TO SUPPLEMENT

REINFORCING INCLUDE NON-METALLIC MESH AND #3 FRP OR GALVANIZED STEEL

BARS.
