Delpatch™ Elastomeric Concrete

1. High-load bearing capacity – Handles the weight of C-4s, 747s, and heavy truck traffic.

2. Outstanding anti-spalling properties – Delpatch™ is a long-term solution for high-performance pavement repairs.

3. Excellent adhesion to concrete and steel – Laboratory tests show Delpatch™ withstands over 400 psi with concrete and 500 psi with steel.

4. Impact resistant – Under bitterly cold conditions Delpatch™ with-stands heavy impact, unlike epoxy and concrete-based materials that shatter.

5. High compressive strength – Delpatch™ can handle heavy psi pressure before deflecting, and its memory allows it to return to its near original state after deflection.

6. Chemical resistant – Delpatch™ resists commonly used chemicals such as ASTM Oil #1, ASTM Fuel A, Ethylene Glycol, Freon, Isopropyl Alcohol, JP-4 JetFuel, Silicone Grease, Sodium Chloride, Mineral Oil, Trisodium Phosphate, and Potassium Acetate.

7. Easy to install – Delpatch™ is self-leveling and has a rapid cure time. This minimizes expensive downtime and allows for the return of traffic often within an hour of final pour. It also protects work crews by minimizing their exposure to heavy traffic.

8. Flexibility – Cement, Phosphate, Epoxy and most other high early strength repair materials prematurely fail because they are rigid. Rigid repair materials installed in rigid pavement require that the materials have similar coefficient of expansion. Most do not and, as a result, destroy the patch and the surrounding concrete. Delpatch™ utilizes a unique urethane chemistry to provide a flexible patch that will deflect as surrounding concrete expands and contracts, rather than destroy it.

In 1983, The D.S. Brown Company introduced Delcrete™ Elastomeric Concrete on I-10 in Louisiana as a bridge expansion joint assembly structural anchoring and nosing material. The rigid, yet flexible connection Delcrete™ provided between steel and concrete soon made it the premier solution for bridge and highway spall repair. Yet the need still existed for a permanent repair solution for high performance pavements which would offer minimal downtime and, at the same time, limit exposure of work crews to traffic. D.S. Brown engineers accepted the challenge and formulated Delpatch™ Elastomeric Concrete from the original Delcrete™ product. Delpatch™ Elastomeric Concrete, a new generation of elastomeric concrete, has two main uses. First, it is an excellent patching material for cracks and spalls on airport runways and highways. Second, Delpatch™ Elastomeric Concrete provides an easy to use solution in retrofitting airport runways with lighting.

Delpatch™ Elastomeric Concrete Applications

Concrete Spall RepairMany transportation en-gineers across the coun-try have used Delpatch™ Elastomeric Concrete as a permanent solution for the repair of cracks and spalls in airport runways and highways. These pro-fessionals have discovered that Delpatch™ Elastomeric Concrete allows airport runway and highway proj-ects to be back in use in as little as one hour after the final pour. In addition, its ability to withstand a variety of common-ly-used chemicals as well as extreme temperature changes make Delpatch™ Elastomeric Concrete the preferred solution for pavement repair.

Airfield LightingDelpatch™ Elastomeric Concrete has been successfully used to ret-rofit airport runways and taxiways with lights. Its great uniform flow characteristics allow Delpatch™ Elastomeric Concrete to flow be-neath and over the conduit, offer-ing support to the conduit from below and protection on top.Delpatch™ Elastomeric Concrete typically hardens within one hour of final pour, thereby allowing ex-pensive downtime on the runway to be limited. To date, over 100,000 feet of trench has been successfully backfilled with Delpatch™ Elastomeric Concrete products.

MG-KRETETM is ideal for a virtually unlimitedrange of concrete repairs:

including thin overlays, pouring into forms,staircases or as a fast-set plug. In addition,MG-KRETETM can be troweled vertically and overhead, and cures very rapidly in all weatherconditions - most applications can be returned to sevice within 1 hour.

MG-KRETETM lasts much longer and withstands wearand heavy traffic superior to traditional cement basedpatch material. It has a tenacious bond, does notshrink, creating a surface that is more impervious tomoisture, salt, gas and oils and requires no long termmaintenance.

MG-KRETETM sets within one hour in freezing temperatures, helping to dramatically cut production downtime.

MIXING Keep all materials dry, DO NOT ADD WATER TO THE MIX. Maintaining the mix ratio as supplied, i.e. one container of liquid activator to one bag of dry component, will give a trowellable consistency suitable for most floor applications, however the slump may be adjusted to the applicator's preference or to suit the specific job conditions by increasing either of the two components. DO NOT ADJUST THE SLUMP BY THE ADDI-TION OF WATER. Mix the two components by mechanical means until all the mater ial is wetted, and place quickly. Dry pea gravel may be added to the mix to increase the yield on deep placements. APPLICATION INSTRUCTIONS Surface must be clean, dry and free of loose material. Remove all dirt from area to be covered leaving a rough, clean surface. For applications at ambient temperatures below 50ºF (10ºC) 1261 LOW TEMP ACCELERATOR must be used to ensure a full cure. With temperatures above 70ºF (21ºC) the 1263 HIGH TEMPERATURE RETARDER can be used to extend the working time. Do not pre-wet surface with water. Keep an adequate supply of water on hand to keep equipment clean. Thoroughly dry all equipment before using 1260 MG-KRETE™. FINISHING 1260 MG-KRETE™ may be finished with screed, trowel or broom. Do not rework material after it has begun to set. OVER COATING - Allow 1260 MG-KRETE™ at least 24 hours to cure before over coating. The cured surface must be acid washed, sandblasted or mechanically abraded before coating to ensure sound bonding. SPECIAL HANDLING Store materials in a clean dry area away from direct heat. Setting time of the mixed material will be greatly accelerated if the components are stored in a warm or hot environment, conversely, the setting time is extended if the materials are kept cool. Flush all spills with water. Clean all tools with water immediately after each use. Do not attempt to place 1260 MG-KRETE™ in water or where running water will disturb the worksite or rain is imminent. SAFETY Please refer to SDS at www.imcotechnologies.com. Use the same precautions as when working with conven-tional concrete. Although the materials are non-toxic it is good practice to protect exposed skin areas and to wear a face mask to prevent inhalation of the aggregate particles. A small amount of ammonia gas is released during the cure, venting of indoor areas may be required in some applications, although this will present no problems outdoors. Neither of the components nor the mixed product are flammable. WARRANTY DISCLAIMER
