Kaufman Products K Pro UC Epoxy Grout

K Pro UC Epoxy Grout is ideal for the restoration of structural pile members in underwater applications as an epoxy grout to fill the annular space between pile jackets and pilings. Extremely flowable and easy to pump, K Pro UC Epoxy Grout is ideal for plural component pumping applications, both above and below the water line, where large volumes of epoxy grout must be placed.

K Pro UC Epoxy Grout is ideal for tremie applications, as well as for other marine applications, such as piers, sea walls, dams, bridges, and other offshore structures. K Pro UC Epoxy Grout is impact resistant as well.

Additionally, K Pro UC Epoxy Grout is also a multi-purpose system, and may be used in many other types of epoxy grout applications, in both wet and dry environments where a high strength epoxy grout is necessary.

Surface Preparation: Piling surfaces must be clean and sound. Remove all grease, oil, wax, curing compound, sealers, laitance, loose concrete or wood, rust, marine growth, and other foreign matter that would act as a bond-breaker. Water-blasting and/or a wire brush are the preferred methods of preparation to provide an open textured profile. A concrete surface profile (CSP) as per ICRI Guideline 310.2R of 6-9 must be achieved for proper bonding adhesion to concrete.

Steel surfaces must be prepared by water-jetting or other mechanical means required to achieve SSPC-SP 12/NACE 5 WJ-4. Wood surfaces may best be prepared by high-pressure water blasting to achieve a sound surface free of contaminants. All areas that have excessive section loss, whether it is concrete, steel, or wood, should be repaired or replaced.

Proportioning/Mixing: The volumetric ratio of K Pro UC Epoxy Grout is 2:1 (A:B) for the epoxy to hardener. To mix, proportion two parts A and 1 part B into a clean pail. Mix thoroughly for 2-3 minutes with a paddle on a low speed (400-600 rpm) drill until blend is a uniform color. Take care to avoid entrapping air in the mixed material. Slowly add the C Component to produce either a flowable or a stiff consistency epoxy grout. Mix all three components for 2-3 minutes or until uniformly blended.

K Pro UC Epoxy Grout may be pumped. The annular space between the pile jacket and piling must be a minimum of ½’. Install pumping ports at 90o from the tongue and groove joint, alternating sides. The first port should be at least 9-12” from the bottom. Place subsequent ports at a maximum of 5 feet vertical spacing, while alternating sides. Always pump from the lowest port, and move upwards. Never exceed 10 feet pumping distance between ports. All submerged forms should be inspected prior to epoxy mortar application to prevent leaks or failures, and should be checked during placement.

K Pro UC Epoxy Grout may be poured or used in tremie applications; however it is imperative that the hose be placed at the bottom of the form. The tremie hose shall be retracted as the annular space fills.

When ether pumping, pouring, or the tremie method of application, the water will be displaced out the top of the form. Continue to fill the annular space until undiluted epoxy grout overflows from the sleeve. Once the epoxy mortar has cured adequately, top off with epoxy mortar, and finish as desired.

Underwater product placement should only be attempted by experienced diving contractors. Read Safety Data Sheet before using. Please refer to the General Epoxy Instructions for complete details on proper application during cold and hot weather. Take care always to prevent spills.

Store dry at 40-95°F. Condition material to 65-85°F before using.
