1. THE DESIGN FOR THIS PROJECT WAS BASED ON THE SURVEY PROVIDED BY THE CONTRACTOR

(D-SQUARE CONSTRUCTION, LLC) ON NOVEMBER 5, 2015. ALL DISCREPANCIES FOUND

DURING CONSTRUCTION SHALL BE BROUGHT TO THE ATTENTION OF THE COTR AND ENGINEER.

2. THE ABOVE NOTED SURVEY WAS MODIFIED BY THE CONTRACTOR ON DECEMBER 17, 2015.

CONTRACTOR VERIFIED BOOSTER PUMP SUMP DEPTH, SURVEY SUMP DEPTH MODIFIED FROM

ELEVATION 1132.34, TO VERIFIED ELEVATION 1136.38. THIS MODIFICATION ALSO INCLUDES THE

ADDITION OF BOOSTER SUMP MANHOLE RIM ELEVATION 1152.03.

REPAIR PROCEDURES (REFERENCE: XYPEX METHOD STATEMENT, 2015-11)

STEP 1: CHIP OUT DEFECTIVE, POORLY CONSOLIDATED OR DELAMINATED CONCRETE UNTIL SOUND CONCRETE

IS ENCOUNTERED.

STEP 2: IF CORRODED REINFORCING STEEL (REBAR) IS ENCOUNTERED, THE DEFECTIVE REBAR SHOULD BE FULLY EXPOSED BY CHIPPING AND REMOVING ANY CONCRETE COVER UNTIL CORROSION FREE REBAR IS REACHED. REMOVE ALL CORROSION FROM THE EXPOSED REBAR AND CHIP ALL THE WAY AROUND IT SUCH THAT MORTAR CAN BE PLACED ON ALL SIDES OF THE REBAR. IF DUE TO CORROSION, THE CROSS SECTION OF THE REBAR IS NOTICEABLY REDUCED, ADVICE FROM A STRUCTURAL ENGINEER ON REBAR

REPLACEMENT IS RECOMMENDED.

STEP 3: IF THERE ARE ACTIVE WATER LEAKS IN THE EXCAVATED AREA, CREATE A VOID OF APPROXIMATELY 1" DIAMETER (25 mm) BY ABOUT 1" (25 mm) DEEP AT EACH LEAK POINT.

STEP 4: DELINEATE THE CHIPPED AREA TO AS CLOSE TO A SIMPLE SQUARE SHAPE AS IS PRACTICAL BY SAW CUTTING TO 3/4" (19 mm) DEEP OR AS SPECIFIED. IF CUTTING TO THIS DEPTH WILL DAMAGE THE REBAR THE REDUCE THE DEPTH OF THE CUT SUCH THAT THE REINFORCEMENT STEEL IS NOT IMPACTED. REMOVE THE CONCRETE WITHIN THE DESIGNATED REPAIR AREA, AND TO THE SAWCUT IN REPAIR "B", TO CREATE

A STRAIGHT SIDED, EXCAVATED AREA.

STEP 5: REMOVE ALL THOSE MATERIALS IN THE EXCAVATED AREA USING A 3,500 - 5,000 PSI (250 - 350 BAR) PRESSURE WASH AND SATURATE THE AREA WITH WATER. ALLOW THE CONCRETE TO ABSORB THE WATER

UNTIL IT IS A "SATURATED, SURFACE DRY" CONDITION.

STEP 6: STOP ANY ACTIVE LEAKING BY FILLING THE 1" (25 mm) DIAMETER BY 1" (25 mm) DEEP VOIDS AT THE

LEAK POINTS WITH XYPEX "PATCH'N PLUG".

STEP 7: (REPAIR "A"): APPLY A SCRUB COAT OF THE SELECTED REPAIR MORTAR TO THE INSIDE SURFACE OF THE PATCH AREA AND, WHILE IT IS STILL WET OR "GREEN", FILL THE ENTIRE AREA TO THE SURFACE WITH THE SAME MORTAR. NOTE THAT "PATCH'N PLUG" IS A VERY RAPID SETTING MATERIAL SO IT MUST BE APPLIED

IMMEDIATELY AFTER THE SCRUB COAT.

(REPAIR "B"): APPLY A SCRUB COAT OF XYPEX "MEGAMIX II" MORTAR TO THE INSIDE SURFACE OF THE PATCH AREA AND, WHILE IT IS STILL WET OR "GREEN", FILL THE ENTIRE AREA TO THE SURFACE WITH

"MEGAMIX II".

STEP 8: (REPAIR "A"): IF THE VOID IS DEEPER THAN 2" (50 mm) IT SHOULD BE FILLED IN LAYERS (LIFTS) OF NOT MORE THAN 2" (50 mm).

(REPAIR "B"): IF THE VOID IS DEEPER THAN 2" (50 mm) ON A VERTICAL OR HORIZONTAL SURFACE, OR

2" (37 mm) ON AN OVERHEAD SURFACE, THE VOID SHOULD BE FILLED IN LAYERS (LIFTS) OF NOT MORE

THAN THE STATED THICKNESS.

(REPAIR "A" AND "B"): FOR MECHANICAL BOND OF THE NEXT LAYER, PROVIDE PROFILE BY SCORING THE SURFACE OF THE INSTALLED MORTAR WITH THE TIP OF THE TROWEL. IN SITUATIONS WHERE THE REPAIR AREA REQUIRES MULTIPLE LIFTS, REINFORCING SUCH AS WIRE MESH MECHANICALLY ATTACHED TO THE

SUBSTRATE SHOULD BE CONSIDERED.

STEP 9: • • • • • •• •• • • ••• • •• • • • • ••• • • • • • •• • •• ••• • • • • • •• ••• •• •• • •• • ••• • •••• •• •• • •• •••• • • • ••• • •• • • • •• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • AREA EXTENDING TO 6" (150 mm) MINIMUM BEYOND THE EDGE OF THE PATCH.

STEP 10: (REPAIR "A"): CURE THE REPAIR AREA BY KEEPING MOIST BY FOG SPRAYING PERIODICALLY WITH WATER

FOR TWO TO THREE DAYS. OPEN TO WATER CONTACT PER XYPEX COATINGS GUIDELINES.

(REPAIR "B"): CURE THE REPAIR AREA BY KEEPING MOIST BY FOG SPRAYING PERIODICALLY WITH WATER

FOR TWO TO THREE DAYS. OPEN TO WATER CONTACT PER XYPEX COATINGS GUIDELINES.

REPAIR PROCEDURES (REFERENCE: XYPEX METHOD STATEMENT, 2016-01)

STEP 1: (REPAIR "C"): CHIP OUT A "U" SHAPED SLOT PER THE REPAIR "C" DETAIL ABOVE AND DEPENDING ON

THE WALL TO SLAB INTERFACE CONFIGURATION, SUCH THAT THE BOTTOM CORNER OF THE SLOT IS

CENTERED OVER THE CONSTRUCTION JOINT.

(REPAIR "D"): CHIP OUT CRACK/JOINT IN A "U" SHAPED SLOT AS PER THE REPAIR "D" DETAIL ABOVE.

(REPAIR "C" AND "D"): THE SLOT IS TO BE 1" (25 mm) WIDE BY AT LEAST 1.5" (35 mm) DEEP. A "V" SHAPED SLOT IS NOT ACCEPTABLE. THE SLOT MAY BE SAW CUT INSTEAD OF CHIPPED BUT ENSURE THAT THE SLOT IS DOVETAILED OR OTHERWISE SHAPED SUCH THAT THERE WILL BE MECHANICAL INTERLOCK OF

MATERIALS PLACED INTO THE SLOT AT A LATER STAGE.

STEP 2: REMOVE ALL LOOSE MATERIALS WITHIN THE SLOT AND TO 6" (150 mm) ON EITHER SIDE OF SLOT.

CLEAN, PROFILE (ICRI CSP-3) AND SATURATE THIS AREA WITH WATER. ALLOW WATER TO SOAK INTO

CONCRETE AND THEN REMOVE ALL SURFACE WATER.

STEP 3: • • • • • •• • • •• • • • • • •• • • ••• • •• • • • • ••• • • • • • •• • •• ••• ••• •• • • • • • • • •• • •• •• •• • •• • ••• • ••• •• •• • •• ••••• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • THE SLOT AND TO 6" (150 mm) UP/DOWN THE WALL AND ONTO THE SLAB AWAY FROM THE SLOT.

APPLICATION MAY BE PERFORMED BY BRUSH OR GLOVED HAND.

STEP 4: WHILE SLURRY COAT IS STILL TACKY, FILL SLOT TO SURFACE WITH XYPEX "CONCENTRATE" "DRY-PAC" MIXED IN THE FOLLOWING PRO-PORTIONS: ONE PART CLEAN WATER TO SIX PARTS "CONCENTRATE" BY VOLUME. BLEND "DRY-PAC" BY TROWEL FOR 10-15 SECONDS ONLY (LUMPS SHOULD BE PRESENT IN THE MIXTURE). APPLY "DRY-PAC" BY GLOVED HAND, AND THEN COMPRESS IT TIGHTLY USING A PNEUMATIC

PACKING DEVICE OR A HAMMER AND BLOCK.

STEP 5: WET "DRY-PAC" SURFACE LIGHTLY WITH WATER, THEN APPLY A SLURRY COAT OF XYPEX (REPAIR "C"): TO 6" (150 mm) UP/DOWN THE WALL AND ONTO THE SLAB AWAY FROM THE SLOT, (REPAIR "D"): TO 6" (150 mm) STRIP ON EITHER SIDE OF SLOT.

STEP 6: CURE THE REPAIR AREA BY KEEPING MOIST BY FOG SPRAYING PERIODICALLY WITH WATER FOR TWO TO

THREE DAYS. OPEN TO WATER CONTACT PER XYPEX COATINGS GUIDELINES.
