SPALLING CONCRETE REPAIR PROCEDURES:

1. CREATE AN ENLARGED CAVITY BY PROVIDING A SAW CUT EDGE 1/4" TO 1/2" IN DEPTH, LOCATED A MINIMUM OF 2" IN SOUND CONCRETE

BEYOND THE PERIMETER OF THE CAVITY. DO NOT DAMAGE REINFORCING STEEL. ALL SAWCUTS SHALL BE RECTANGULAR IN SHAPE.

2. DEPTH OF SOUND SUBSTRATE 3/4" BEYOND CORRODED REINFORCING STEEL OR GREATER THAN THE LARGEST AGGREGATE COVERED.

CONCRETE REMOVAL SHALL EXTEND ALONG LENGTH OF REINFORCING STEEL TO LOCATIONS FREE OF CORROSION.

3. SCARIFY AND CLEAN THE CAVITY WITH POTABLE WATER. REMOVE ANY BOND INHIBITIVE MATERIALS.

4. REINFORCING STEEL TO BE MECHANICALLY CLEANED (FREE OF ALL RUST) AND COATED WITH SIKA ARMATEC 110 EPOCEM (OR APPROVED

EQUAL) IN ACCORDANCE WITH MANUFACTURER'S INSTRUCTIONS.

5. DRILL AND SET 1/4" S.S. THREADED RODS @ MAX 6" INTERVALS WITH 2" MINIMUM EMBEDMENT WHERE DEPTH OF SPALL EXCEEDS 1 1/2" IN

VERTICAL AND UNDERSIDE REPAIRS. APPLY MODIFIED REPAIR LOW SHRINK MORTAR AS RECOMMENDED BY THE MANUFACTURER.

TO BE USED IF CONCRETE IS DAMAGED DURING REMOVAL

OF WALL IN FUTURE DRIVE AISLES. FOR BIDDING PURPOSES:

ASSUME (3) LOCATIONS

FOR CRACKS 3/16" WIDE OR LESS: WHILE

CRACK IS WET, INJECT CRACK WITH JAHN

M30 #31 GROUT PER MANUFACTURER'S

SPECIFICATIONS.

WHEN REPAIRING HORIZONTAL SURFACES USING REPAIR MORTAR, APPLY MATERIAL FLUSH TO THE SURFACE AND FINISH TO A TIGHT STEEL TROWELED

FINISH, FLOAT, OR BROOM TO ACHIEVE A TEXTURED EFFECT. WHEN REPAIRING VERTICAL SURFACES, BUILD UP MATERIAL BEYOND THE SURFACE OF THE

SUBSTRATE.

INCORRECT: FEATHERED EDGE

CORRECT SQUARE CUT

NOTE:

1. REMOVE ALL LOOSE MORTAR AND MASONRY PRIOR TO INSTALLATION OF THE REPAIR MORTAR. SOUND MASONRY WITH A HAMMER TO VERIFY ITS INTEGRITY.

IF NECESSARY, CUT AWAY AN ADDITIONAL 1/2" OF THE SUBSTRATE TO ENSURE THE SURFACE TO BE REPAIRED IS SOLID AND STABLE. REMOVE ANY SEALANT

RESIDUE.

2. CUT THE EDGES OF THE REPAIR AREA TO PROVIDE A MINIMUM DEPTH OF 1/2". THE EDGES OF THE REPAIR SHOULD BE SQUARE CUT. DO NOT ALLOW ANY

FEATHERED EDGES IN THE REPAIR AREA. REMOVE ALL DETERIORATED STONE PLUS AN ADDITIONAL 1/4" TO SOUND SUBSTRATE.

3. WASH PREPARED SURFACE WITH CLEAN WATER AND A BRISTLE BRUSH TO REMOVE DUST FROM THE PORES.

4. CUT OUT AND REPLACE ALL REINFORCEMENT WHOSE STRUCTURAL INTEGRITY IS IN QUESTION. STRUCTURALLY SOUND CORRODED REINFORCING STEEL MUST

BE MECHANICALLY ABRADED TO A WHITE METAL FINISH. MECHANICAL MEANS, SUCH AS SANDBLASTING, GRINDING OR WIRE BRUSHING ARE ACCEPTABLE.

COAT EXPOSED STEEL WITH CORONADO SURFACE TOLERANT MASTIC, 113 LINE (CORONADO INDUSTRIAL COATINGS) (OR APPROVED EQUAL). APPLY REPAIR

MORTAR ONLY AFTER COATING IS COMPLETELY DRY.

SURFACE SPALL REPAIR FOR CONCRETE ELEMENTS MAY BE CONSIDERED AS AN ALTERNATIVE TO REPLACEMENT ONLY AS APPROVED BY THE ENGINEER ON A SPECIFIC

CASE BASIS.

EXISTING CAST-IN-PLACE ELEMENT

APPLY A "PEANUT BUTTER" COAT (REPAIR MORTAR MIXED WITH WATER TO THE CONSISTENCY OF WET PUTTY), APPROXIMATELY 1/8" THICK. TO ACHIEVE PROPER

BOND, THE "PEANUT BUTTER" COAT MUST NOT DRY OUT PRIOR TO APPLICATION OF MORTAR.

NOTES:

1. MOISTEN THE SUBSTRATE USING CLEAN WATER. REPAIR MORTAR SHOULD BE APPLIED TO A GLISTENING WET SURFACE ON VERTICAL APPLICATIONS AND TO A

DAMPENED SURFACE ON HORIZONTAL APPLICATIONS (WITH NO POOLING WATER).

2. REPAIR MORTAR MAY BE PLACED IN DEEP APPLICATIONS USING SUCCESSIVE LIFTS. IF A CEMENT SKIN FORMS BETWEEN APPLICATIONS (THE SURFACE WILL APPEAR

GLOSSY), SCRAPE AWAY ENOUGH OF THE SURFACE TO REMOVE THE SKIN (ABOUT 1/16" OF MATERIAL) THIS WILL OPEN THE PORES BEFORE AN ADDITIONAL LAYER

OF MATERIAL IS APPLIED. THE SURFACE SHOULD BE MOISTENED AGAIN BEFORE CONTINUING THE APPLICATION.

3. ALLOW MORTAR 30 TO 60 MINUTES TO SET SLIGHTLY (WAIT TIME WILL VARY WITH TEMPERATURE AND HUMIDITY-LONGER IN COOL WEATHER), AND THEN SCRAPE

OFF EXCESS MATERIAL USING A STRAIGHT EDGE (A PLASTERER'S MITER ROD IS GOOD FOR THIS). DO NOT PRESS DOWN OR "FLOAT" THE REPAIR. WHERE REPAIRS

OCCUR AT PANEL EDGES OR CORNERS, FORM MORTAR TO MATCH THE PROFILE OF THE SURROUNDING MASONRY. IN ALL CASES, FINISH AND TEXTURE REPAIR SO

THAT IT IS AS INDISTINGUISHABLE AS POSSIBLE FROM THE ADJACENT MASONRY.
