TACTALK The Future of Concrete Repair

One of my favorite sayings is “Do unto your office, then typically concrete is repaired when cracks appear, often future before your future does unto you.” Like with rust staining from corrosion. This is analogous to a visit to the many other things, this is true of concrete repair. emergency room or perhaps even hospice care.

rapidly accelerating as our standard of living improves. (Fig. 1and Fig. 2 27, 28, 29) In my opinion, the concrete repair industry needs to evolve into a real profession, rather than remain as an auxiliary to new concrete construction. The most excitement in civil engineering is towards new construction, yet the volume of existing concrete is much greater than new construction and as previously pointed out, our infrastructure continues to deteriorate. We need to convince the owners and specifiers that protection and maintenance of concrete is a better investment over the life cycle of a structure than waiting for rust coming out of cracks.30 n

Today, the Battery Building is on the National Register of Historic Places, the New Jersey Register of Historic Places, and designated locally by the Township of West Orange as a historic site. Fig. 2: Inside the Edison Battery Building (Credit: The New York Times, Dec. 21, 2017) PROBLEMS THAT PROMOTED REPAIRS Weathering over the last 100 years had taken its toll on the Edison Battery Building, and being vacant for the last decade did not help the cause (Fig. 3). From spalling concrete, corrosion due to the lack of concrete cover over reinforcing steel, cracking, leaking joints, and unsuccessful concrete repair attempts over the years, the 130,000 sf (12,075 sm) concrete façade of this iconic structure was in a dilapidated condition (Fig. 4), a direct result of an aging structure and lack of adequate maintenance of the building. e building, however, was in good structural condition. RESTORATION OBJECTIVE e Edison Battery Building was to be repurposed to a boutique residential building, including luxury lofts with a —tness lobby, swimming pool and sky lounge overlooking the NYC skyline with the following objectives: Fig. 3: From an iconic structure to a dilapidated building • the building had to be restored to its original look; • the look should be contemporary and historical; and • the look should appear fresh and new as it would when built the —rst time.

e Edison Battery Building restoration project was part of the complete Edison Village Downtown Redevelopment project, developed over a ten-year period. is redevelopment plan was originally adopted in 2003. e scope of the entire project was to redevelop Block 66, Lots 1, 5 and 7 (the “Edison Battery Building”) and to construct: • 334 residential rental units; • 16,000 sf (1485 sm) of retail space; • approximately 31,700 sf (2945 sm) of amenity support space; • parking structure containing approximately 635 parking spaces; and Fig. 4: Existing building façade prior to repairs • public infrastructure (e.g. roads, utilities, sidewalks).

16 CONCRETE REPAIR BULLETIN NOVEMBER/DECEMBER 2018 WWW.ICRI.ORG RESTORATION PROGRAM

Concrete Spall Repairs Hand-Applied Repairs Repair areas that were 1 in (25 mm) or less in thickness used a single component, hand-applied non-sag mortar. e repair area was mechanically prepared with a chipping hammer and saw cuts completed to de
ne the repair perimeter (Fig. 5). A Concrete Surface Pro
le (CSP) 5-6 was achieved to make sure that adequate preparation was performed for the repair material to bond to the parent concrete.

Additionally, a bonding agent was used to supplement the mechanical bond, and the reinforcing steel was protected with the same material. A total of 2,500 sf (232 sm) of the façade was repaired using this technique. Fig. 5: Hand-applied repair Form and Pour Repairs Deeper spalls were repaired with the form and pour technique, and were primarily performed to repair the window sills (Fig. 6). Concrete preparation was completed in accordance with the guidelines of the International Concrete Repair Institute. Prior to forming up the area, the steel was cleaned and primed and the concrete was coated with a reinforcement protection coating. A form and pour, ˆowable concrete mix was poured in the forms which were stripped after seven days. In very few cases where the depth of the concrete was very deep, rebar splicing was done to make sure that the repair areas were tied to the original spiral bar. A total of 7,500 sf (697 sm) of the façade was repaired with this technique.

Crack Repairs Cracks on the building were initially identi
ed for repair with epoxy. However, after determining that most of the cracks were non-moving, cracks were saw cut into rectangular joints and repaired with the same non-sag mortar used for spall repairs. Fig. 6: Form and pour repair is procedure would ensure that the crack repair lines would not show through the
nal
nish on the façade. Some cracks were repaired with gravity fed resin or crack injection.

Leveling Coat e concrete façade had to be leveled to prepare the surface with a parging material. A factory proportioned polymer modi
ed material was used to parge the entire 130,000 sf (12,075 sm) of the façade (Fig. 7). e leveling material was instrumental in getting the concrete to a
nish on which a waterproo
ng acrylic coating could be successfully used.

Façade Coating After the leveling coat, a waterproo
ng coating was installed for aesthetics and protection (Fig. 8). A coating with crack bridging was selected to coat the entire building façade. To meet the requirements of the historical commission, a textured base coat was selected to cover the blemishes and maintain some of the look of the old concrete. No less than twenty color samples were installed on the building as mock-ups for approval by the historical commission. e selected

After evaluating the results, the cause of the distress in the structure, consisting of delamination and spalling with exposed reinforcing steel, was determined and three primary causes for the observed distress were identied:

1. e distress recorded on the top of the ramp slabs was determined to be caused by high chloride ion levels in the lower ve levels of the six-level ramp. On these levels, Fig. 2: Original slab edge deterioration chloride contents exceeding the threshold amount necessary to induce corrosion of the reinforcing steel were found in the top 2.5 in (64 mm) of the slab. 2. e distress observed on the underside of the ramp slabs was caused by cracking at old repair areas in the top slab. 3. For the deterioration occurring on and below the concrete knee walls, insufficient concrete cover on the steel reinforcing and plates was identied as the cause of the distress. SOLUTION ANALYSIS Solutions were developed to address the causes of distress in consideration of alternative service life expectations.

Chloride Ion Content To address the chloride ion content problem with the ramp slabs, removal and replacement of the top 2.5 to 3 in (64 to 76 Fig. 3: Demolished ramp slab surface with supplemental post-tension reinforcing installed throughout central cylinder mm) of the concrete ‡oor slab was selected to oˆer a long-term service life expectation. is solution represented a potential structural problem, however, given that the slab was post- tensioned. Prior to being able to recommend that the top portion of the slab be removed, a structural analysis was necessary to determine the post-tensioned reinforcing forces on the original slab section, the reduced slab section (once the top portion of the slab was removed), and the nal slab section (with the original slab and new topping slab). Upon completion of the analysis, it was determined that the top slab section could be removed if the perimeter of the ramp was shored and supplemental post-tensioned cables were added to the nal cross-section (Fig. 3 and 4).

Supplemental Post-Tensioned Cables e requirement for the supplemental post-tensioned cables Fig. 4: Exposed post-tensioned tendon anchor heads at central cylinder influenced the decision to recommend a high quality conventional concrete material with a compressive strength of 6,000 psi (41 MPa) to closely match the existing concrete in conjunction with the application of a hybrid polyurethane strength. In addition, the use of a shrinkage-compensating ‡uid-applied membrane with epoxy wear course and specialized admixture was recommended to minimize cracking in the new aggregate on the ramp top surface. The repair material topping slab. recommended for the underside slab repairs was a polymer- modied cementitious material to facilitate use of the form- Underside Slab Condition and Water Infiltration and-pump repair technique (Fig. 5 and 6). e repair material Problems was selected to have compressive stiˆness characteristics that To address the underside slab condition and water inltration closely matched that of the existing concrete. is was necessary problems, conventional partial-area repairs were recommended to provide uniform compressive stress distribution throughout

WWW.ICRI.ORG NOVEMBER/DECEMBER 2018 CONCRETE REPAIR BULLETIN 21 the concrete slab when stressing supplemental post-tensioned reinforcement.

Concrete Cover Issues To address the concrete cover problem on the post-tensioned reinforcing anchor plates on the perimeter of the ramp, a new concrete cap was installed to provide suitable cover for the plates. In addition, a drip edge was provided to prevent water from running down the underside of the ramps (Fig. 7). Although this repair detail reduced the depth of the reveal at the slab perimeter, the architectural appearance of the ramp was not signicantly changed. To address the concrete cover problem on the existing reinforcing steel in the knee walls (Fig. 8), the repair areas were slightly over-built to obtain suitable concrete Fig. 5: Slab edge soft demolition and formwork cover on the reinforcing steel. REHABILITATION e repair solutions described above were incorporated into the contract documents and issued for bidding by experienced repair contractors. e successful bidder was awarded the contract in the summer of 1997 and the work was immediately scheduled to be completed in under 10 weeks during the summer to coincide with the garage’s oƒ-peak season.

Garage Ergonomics Prior to beginning repairs, the tra c in the garage required re-routing as the helix was the only means of exit for the upper levels of the garage and closing the garage was not an option. After considering alternate scenarios to solve this dilemma, a solution was developed to convert the one-way tra c ‡ow into two-way tra c. To accommodate the two-way tra c on the upper six levels, turn around areas were established on alternating levels to facilitate cars changing direction. Although the turnaround areas resulted in a reduction in parking spaces, the tra c ‡ow was not signicantly hampered and the disruption to patrons was minimized.

Fast-Tracked Construction Once parking tra c was re-routed, the helix ramp was closed, and construction commenced. Given the aggressive construction schedule and limited work area, methods to expedite the repair Fig. 6: Slab edge formwork and shoring process were implemented. e primary time-saving measure utilized during the rehabilitation was hydrodemolition, which is a process utilizing water under very high pressure (about 10,000 psi [69 MPa]) to demolish concrete (Fig. 9). is method was used in lieu of conventional jackhammers to remove the top section of chloride-contaminated concrete on the ramp slabs and resulted in signicant time savings.

Completion Following industry standard concrete repair practices and incorporating state-of-the-art materials, the rehabilitation of the ramp was completed on schedule. One of the most important reasons for the success of the project was that the process involved experienced parties for identifying and addressing the causes of the distress in the structure and developing and implementing a repair approach aimed at providing a long-term Fig. 7. Completed slab soft repair with integral drip edge service life extension.

PAST, PRESENT & FUTURE Prior to implementing the rehabilitation described above, a previous repair of the helix ramp had been undertaken. Partial- area repairs completed during that project were found to be deteriorated at the time of the condition assessment performed in 1996.

Given this situation, the concern becomes whether past repair methods and materials addressed the cause(s) of the distress in the structure. Unfortunately, past evaluation and testing techniques fall short of the standards today. e lack of specialized knowledge about the corrosion process and practice of engaging an inexperienced contractor are primary reasons that past repairs are more prone to premature failure than repairs completed today.

Initial structural analysis also indicated less ‘add tendon’ reinforcing of the end spans than provided by current design practice. is condition increased the number of slab PT repairs.

To develop an economic repair plan (as construction was continuing), the slab concrete was cored and tested to determine the in-situ concrete compressive strength instead of using assumed values. en, an elasto-plastic nite element analysis was conducted for the slab. is advanced analysis utilized moment redistribution within the indeterminate structure, resulting in a more accurate (higher) calculated capacity of the structural system than provided by typical simplied elastic examination methods. Based on the results from the advanced investigation, 234 critical corroded tendon locations in the slabs were repaired to provide su„cient capacity to support the required loads (Fig. 4). is more precise repair plan saved the Fig. 2: Existing condition discovered at an interior column owner almost US $1.2 million. SINGLE-TEE BEAM AS-BUILT CONDITION, ASSESSMENT AND DESIGN A total of approximately 130 precast single-tee beams are used to support the ve elevated parking slabs. ese beams are typically reinforced with eight ½-in (12.7 mm) diameter straight bonded prestressed strands and two draped twenty-wire unbonded post-tensioning tendons. e unbonded PT tendons exit the beam ends above the beam ‘ange (within the concrete topping), where they connect to threaded anchorage rods that extend through the reinforced concrete columns to anchor at the outer face of the column. is anchorage system allows negative bending moment to develop at beam ends and provides structural integrity at the beam-to-column connections. e unbonded tendon ends and anchorage rods at the beam ends were encased within a shallow grout pocket, which were typically found to be cracked and debonded from the substrate (Fig. 5).

Unsound grout pockets in the beams were opened for inspection, Fig. 3: Many beams were observed to have and the unbonded wires were often found to be severely corroded, completely corroded through tendons with a large proportion of wires completely failed. In-situ de‘ections of the beams were measured to correlate the condition of the tendons to the measured de‘ections of the beams. Based on the developed correlation, sound grout pockets at beams that exhibited a measured de‘ection exceeding the developed critical de‘ection threshold were opened for inspection, as well as beams that were next to slab drains (i.e. likely often exposed to ponding water), and beams that were located to adjacent distress.

CONDITION SURVEY e structural issues prompted an engineering condition survey to evaluate the subgrade garage structure with ndings used to develop a repair program. e survey included visual examination of the entire garage structure with exploratory openings within the overburden above the garage in order to ascertain the condition of the concealed structural and water resisting components. An Fig. 2: Overhead view of subgrade garage exploration pit at the south end of the garage exposed a portion of the stressing end of the post-tension slab and top of the foundation wall. At this location, the existing surface-adhered “peel and stick” cold-applied sheet membrane was debonded and beyond its useful service life. e membrane conditions allowed water to reach and corrode the stressing anchors. Water also traveled within the protective sheathing causing corrosion and subsequent rupture of the post-tension tendons that was observed in the garage below (Fig. 3).

An exploration pit at the north end of the garage exposed the expansion joint. e same type of sheet membrane was revealed, exhibiting similar conditions. Spalling concrete was observed on the large concrete beams and columns directly below this leaking (a) (b) expansion joint. Fig. 3: (a) Corroded post-tension anchor, and (b) Ruptured tendon REPAIR PROGRAM A repair program was developed to address garage leakage and restore structural components to their intended original integrity. The most concerning aspect was determining the extent of deterioration that had already occurred to concealed post-tension components. Assessing the entire slab edge and stressing anchors could not take place without removing 6 ft (1.8 m) of overburden and existing waterproong for the entire length of the structure. e original structural drawings were reviewed to understand the layout and quantity of tendons. e repair program required ongoing evaluation and repair determination during the construction phase, which was scheduled for summer of 2017 to coincide with the replacement of the swimming pools and spa facility at the hotel. e repair program consist of three main components: stressing end repairs, expansion joint repairs, and concrete repairs to members within the garage.

Stressing End Repairs e project included removal of overburden to expose the stressing end of the slab and foundation wall (Fig. 4). e existing debonded sheet membrane and grout pockets were removed for engineer assessment of the stressing anchors, and components were repaired accordingly (Fig. 5). Corroded anchors required slab openings, Fig. 4: Section detail at stressing end and foundation wall (repair drawing) locking o

WWW.ICRI.ORG NOVEMBER/DECEMBER 2018 CONCRETE REPAIR BULLETIN 33 to the existing tendon, placing concrete, stressing, and placing new non-shrink grout at the stressing pockets prior to installing new hot applied reinforced membrane on the slab and foundation wall. By the end of the project, over 1,000 stressing anchors were exposed, evaluated and 364 repairs required. Due to the reconstruction of the adjacent swimming pools and spa facility, space to excavate and store soil was limited. In addition, storing soil above the garage utilizing shoring was not feasible due to the hotel using the garage for parking. ­erefore, the excavation and repairs had to be performed in four consecutive phases.

Expansion Joint Repairs ­is component included removal of overburden to expose the expansion joint and dead end of the slab adjacent to the main hotel building. ­e existing membrane and joint seals were removed Fig. 5: Post-tension repairs in progress (stressing end) for engineer assessment of the slab and identi€cation of required repairs. A new sloped concrete topping and drainage system were installed to reduce water on the expansion joint. ­e drainage system included drain pipe cleanouts in the drain piping below the slab and extensions above the drains to allow regular maintenance and clearing at the landscaped area.

­e waterproo€ng repairs included new expansion joint seals and looped ƒashing sheets over the joint, and hot applied reinforced waterproo€ng membrane and counter ƒashings at the slab and building wall (Fig. 6). Upon completion of waterproo€ng repairs, a drainage layer, expanded polystyrene (foam) blocks, and a 2.5 ft (0.8 m) layer of soil were placed over the slab (Fig. 7). ­e foam blocks were used to reduce the load on the structure and provide easier access to the expansion joint for future serviceability. Fig. 6: New membrane and ashing along the expansion joint and building wall PROJECT CHALLENGES Various challenges were addressed during the repair project and included restraints from site conditions, strict schedule requirements for completion within a four-month period, the magnitude of repairs, scope complexity, and unforeseen conditions. ­e completed project is shown in Figure 8. n
