ISR AG

ISR AG is a durable, crack resistant repair material utilizing ISR (Internal Stress Relief) technology with ECB- Tech corrosion protection, used in repairs over 2″ deep such as parking decks, balconies, and plaza decks. It can be troweled into place or as a form and pour/pump material.

Where to use:

Parking and plaza decks, balconies, and marine structures.

How to apply:

Pour, pump, or hand patch. Additional Information

Performance Characteristics

  • Pumpable sustainable green technology Contains significant concentrations of both pre-and post-consumer recycled content.
  • Low shrinkage Maintains integrity of repair, resists cracking.
  • Thermal compatibility Prevents delamination due to temperature change.
  • ECB-Tech corrosion protection Protects reinforcing steel in repair zone and suppresses ring anode effect.
  • Durable Resistant to weathering action, excellent freeze/thaw stability and abrasion resistance.
  • Low permeability Resistant to deicing salts, carbonation, chloride, and chemical attack.
  • Dimensionally stable Ideal for large areas.
  • Abrasion resistant Hard, durable surface for long term wear.

Surface Preparation

  • Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper bond.
  • Saw cut edges with a diamond blade at a 90° angle to eliminate feather edging. Avoid polishing the edges as this will inhibit bond.
  • Avoid bruising or micro cracking during surface preparation. Refer to ICRI Surface Preparation Guide 03732.
  • Repair zone must be a minimum of 3/4 inch deep, of simple geometry, with no complex edge conditions.
  • Avoid long narrow repairs; these have a tendency to crack.
  • Saturate substrate with clean water, (saturated surface dry/SSD), with no standing water during Application.
  • Remove concrete from corroded steel and several inches beyond to expose non-corroded steel.
  • Provide a 3/4-inch clearance between the concrete and steel.
  • Damaged reinforcing steel should be inspected by a qualified engineer an appropriate action taken.

Mixing

  • Mechanically mix using a mortar mixer.
  • Pour 3 quarts of potable water into a clean mixing vessel and slowly add all of the powder.
  • Mix continuously for 3 minutes to a uniform, lump-free consistency.
  • For trowel applications, do not exceed 3 quarts of water per bag. Proper mix ratio is 6 parts powder to 1 part water.
  • Add additional water to increase slump and flowability for form and pour applications. Do not exceed 3.75 quarts of water per 60 lbs. of material. Proper mix ratio is 5 parts powder to 1 part water.
  • 3.75 quarts of water will produce an 8-inch slump.
  • Allow to “breathe” for 1 minute.
  • Do not overmix, this will entrain excess air.

Application

  • At the time of application, surfaces should be saturated surface dry (SSD) but hold no standing water.
  • Form applications must be consolidated with vibrator.
  • Place material continuously to break points.
  • Finish with a magnesium float or trowel.
  • Avoid overworking material during placement and finishing – this will produce surface (map) cracking.

Curing

  • Dampen the repair with a fine mist of water for 24 hours or moist cure with wet burlap and polyethylene.
  • Protect repair from direct sunlight, wind, rain and frost during curing period.

Clean Up

  • Clean tools and equipment with water immediately after use.
  • Cured material must be removed mechanically.

Coverage/Yield

  • 0.49 ft³/60 lb. bag

Product Handling

  • Packaging 60 lb. paper bag.
  • Shelf Life 12 months when properly stored.
  • Storage Transport and store in cool, clean, dry conditions in unopened containers. High temperature or high humidity will reduce shelf life.

Limitations

  • Do not apply unless substrate and ambient temperature can be maintained at a minimum of 40°F for 24 hours. Refer to ACI Cold Weather Application Guidelines.
  • Cold mixing water and low temperature will retard set. Hot water and high temperature will accelerate set.
  • Protect application from precipitation and high wind for at least 8 hours.
  • Do not add more water than specified, this will lower strengths and cause shrinkage cracking.
  • Avoid overworking material during placement and finishing – this will produce surface (map) cracking.

  • Product is alkaline.
  • Do not ingest.
  • Avoid breathing dust.
  • Avoid contact with skin and eyes.
  • Refer to Safety Data Sheet (SDS) for additional information.

First Aid

  • If swallowed, contact a medical professional immediately. Do not induce vomiting unless directed to do so by a qualified medical professional.
  • In case of skin contact, wash thoroughly with soap and water.
  • In case of eye contact, flush with a high volume of water for at least 15 minutes.
  • For respiratory problems, remove person to fresh air. If difficulty persists, contact a medical professional.

Deep repairs, greater than 2", call for a repair mortar with 3/8" aggregate for successful long-term performance. ISR AG is most often used for horizontal repairs in applications 2" or greater.  It is also used as a filler material for ISR CM when repairs are 2" deep or greater.      

Many repairs mortars can be extended at the jobsite.  This is labor intensive and can raise issues concerning consistency of mixes over the course of the project as well as quality of the aggregate. When possible, the use of a repair mortar produced as a factory blend with 3/8" aggregate in the mix ensures uniform and consistent product through the project.      

ISR AG is formulated to be mixed as a concrete (stiffer) and troweled into place or with higher addition rate of water for form and pour applications.  The benefit of this versatile technology is that it can reduce the number of types of repair mortars needed on a project.

Project History

Beneficial Bank Place, located at 1818 Market Street, a high rise 40-story office building, built in 1974, consists of a cast-in-place, reinforced concrete frame façade. It was designed by renowned Philadelphia firm Ewing Cole and has undergone 3 renovations since being built. It stands 500 feet high and starts as a nine level parking garage topped by thirty floors of office space.
Throughout its 40+ year life, 1818 Market Street has undergone multiple renovations due to corroding rebar and spalling. All exposed rebar was treated with Conproco’s ECB, a zinc-based primer and passive barrier coating that is not a bond breaker when applied to the concrete substrate. This single component, water-based product has up to a 5 day open time making for easily application and cleanup on high rise jobs like this. Its orange color makes it even easier to inspect full coverage.
To achieve a faster set on all vertical repair areas, the contractor trowel applied Quick Shot, our fastest setting cementitious repair mortar. ISR Deck Mix was used on all horizontal applications, including long form-and-pour repairs at the parapets.
