3. Product Description

GENERAL DESCRIPTION Crackbond LR321 Injection Resin is a two component, 2:1 ratio, 100% solids, high modulus, structural epoxy adhesive. It is a solvent free, low odor, high strength, moisture insensitive, low viscosity epoxy system. Crackbond LR321 can be used at temperatures between 40°F -110°F., providing contractors with a choice for injecting cracks in high and low temperature environments. In addition, Crackbond LR321 has a viscosity of 450 cps which is ideal for gravity feed crack injection applications. Crackbond LR321 is an excellent choice where a high strength adhesive with maximum field reliability is desired.

BASIC USE:

Pressure injection of hairline cracks

x	Pre-stressed membrane repairs	–
	bridges, reservoirs, dams, etc.
x	Gravity feed crack repairs

x Bonding agent for concrete, steel and wood structures x Vertical anchor installations

Crackbond LR321 is formulated for use as an injection resin for cracks in wood and concrete structures that are hairline to medium sized in width (1/400 – 1/8”). It has the viscosity of light oil, and low surface tension, allowing it to deeply penetrate fine cracks. It cures to a solid with no shrinkage, bonds to both surfaces of the crack, bonding the structure back to its original monolithic strength.

This bond forms a permanent polymeric adhesion that cannot re- emulsify, and forms a moisture barrier that is resistant to chlorides, corrosion, water, grease, alkalis, salt and mild non-organic acids. Crackbond LR321 is moisture insensitive and will adhere to moist or damp surfaces (for maximum bond, it is better to work on dry surfaces).

LIMITATIONS: Crackbond LR321 is not intended for repairing cracks that are subject to movement. Repairs should be made to the cracked member to eliminate the causes of the cracking before injection is done. Crackbond LR321 is not to be used in areas with standing or seeping water. Steps must be taken to eliminate any standing or flowing water before repairs are made.

The capping material is ground off after the crack is repaired. This step is only necessary if cosmetics are a concern. If the face of the concrete is not exposed then this process is not necessary.

The Crackbond Epoxy Crack Injection System is a unique, high quality, low cost method of structurally re-bonding cracked concrete and wood members. Because structural epoxy has excellent adhesion to concrete and wood surfaces, and has superior physical properties, epoxies are capable of restoring a cracked member to it pre-cracked strength. If properly installed, any new failure of the structure will typically occur in the concrete or wood, not within the epoxy. Examine the Crack: Before repairs are attempted, the crack should be analyzed to determine the type of repair that is required. Cracks in concrete and wood members are classified as either active (moving) or dormant. Dormant cracks may occur from cure shrinkage, stabilized settlement, or one-time overload events such as earthquakes or floods. For dormant cracks in a structure that is to be rehabilitated, structural crack injection is recommended. By contrast, active cracks are those which are caused by inadequate design, seasonal heaving, temperature swings or repeated overloading. Since structural crack injection reintegrates the cracked member, preventing movement at the crack line, it would be necessary to install joints to redirect this movement if structural crack repair is desired.

Required Materials: The required materials are a capping epoxy (such as Crackbond CG3, Crackbond CG300, CP1400 or CP3400), injection resin (Crackbond LR321), injection ports, dispenser, wire brush, protective eye glasses, gloves, tongue depressors or putty knife and mixing nozzles (or injection kit).

Securing ports

V. Plac e and secure injection ports with the Capping Gel material (Crackbond CG3), taking care not to leave any pin-holes. Port spacing should be approximately 6 – 12 inc hes apart (typically the width of the concrete member). Do not a llow the epoxy to block the passage between the port and the cr ack face.

VI. Place additional Crackbond CG3 between the ports making sure the entire face of the crack is sealed off and ports are securely fastene d to the concrete. If the crack is evident and accessible on the bac k side of the concrete member seal with capping gel.

VII. Allow the capping material to cure before injecting crack (at least

XII. Attach the 3/8” tubing (INJ-38 TUB) to the barbed end of no zzle.

XIII. Attach other end of tubing to the bottom injection port. Inject epoxy into port until you either get flow from adjacent port or until epoxy stops flowing. Plug t he port you were injecting in to and attach tubing to adjacent port. Continue procedure until complete.

XIV. Leave the tubing attached to the last port on each crack for 30 seconds under press ure to assure crack is completely filled. XV.Allow Injection resin to c ure (at least 24 hours). Ports and capping material can be removed with a

chisel and/or grinder. Note: Some cracks may take m ore time to inject, especially h air-line cracks. Cracks may be sm aller in widt h (or larger) than they appear from the surface.

DISPENSING AND INJECTION TIPS: DO NOT EXCEED 35 psi AIR PRESSURE TO THE PNEUMATIC DISPENSING TOOL

x	PNEUMATIC DISPENSER:	Must be used with an air pressure regulator.	Start at a low setting and gradually increase pressure as
	needed until desired epoxy flow. Do not exceed 35 psi air pressure. Excessive pressure may result in cartridge plunger leakage.
x	For basement walls (where back side of concrete is not accessible) inject with LR GEL. This is a unique thixotropic gel that will feed
	into small cracks and bridge the back side without runoff.
x	Do not dispense epoxy through gelled mixer nozzle. If epoxy gels in nozzle, replace nozzle before continuing.

Bulk Mix and Application Instructions

Note: compo nent “A” contains epoxy resin and is an irritant / sensitizer; component “B” contains amines an d is a corrosive / sensitizer; p rior to using th e Crackb ond LR321, please consult the material safety data sheet for

proper handling instructions.

I. Surface Preparatio n:

Concrete and Steel: Surfaces must be sound and cleaned so th ere is no dust , dirt, grease, wax, oil or any

other contaminants. Surfaces may be damp (or dry) however there should be no standi ng water. Surfaces may be prepared by shot blasting or other equiv alent mechanical mea ns.

II. Mixing Instructions:

Thoroughly stir each component before mixing them together.

BUG packaging (102 fluid oz kits): Pour the contents of the “B” component pail (h ardener) into the “A” component pail (resin).

B3G, B15G & B150G p ackaging: Mix only the amount of material that can be used before the pot life expires. Proportion parts by volume at a 2:1 ratio (2 parts of component “A” and 1 part of componen t “B”) into a clean pail. Be sure that components are mixed at an exact 2:1 ratio by volume.

Mix thoroughly with a low speed drill (400 – 600 rpm) with a mix paddle attachment (i.e. a jiffy mixer). Carefully scrape the sides and the bottom of the container while mixing. Keep the paddle below the surface of the material to avoid entrapping air. Proper mixing will take at least 3 minutes and when well mixed the material will be free of streaks or lumps.

III. Application:

Bonding fresh concrete to hardened concrete: Using a brush, roller or airless sprayer, apply an even coat of the mixed Crackbond LR321 to the clean and prepared concrete surface. While the epoxy is still tacky, place fresh concrete over the top of the mixed epoxy.

Bonding hardened concrete to hardened concrete: Using a brush, roller or airless sprayer, apply an even coat of the mixed Crackbond LR321 to the clean and prepared concrete surface. Make sure to fill all gaps between the mating concrete surfaces.

Vertical Anchoring: Drill hole into concrete (1/16” – 1/4" diameter larger than the threaded rod or rebar). Typical embedment depth is 9 – 15 bar diameters (9D - 15D). Fill the anchor hole to about 2/3 full with the Crackbond LR321 epoxy. While the epoxy is still wet, place the th readed rod or rebar into the anchor hole while turning clockwise. Do not disturb or bolt-up until minimum bolt up time has passed.

Gravity Feed Crack Injection: Cut a v-groove into the face of the crack/concrete surface, creating a reservoir for the crack repair material. Clean and blow out the crack, removing all dust, dirt, grease, wax, oil or any other contaminants. Pour mixed Crackbond LR321 into a prepared v-grooved crack. Allow epoxy to feed into the crack. Continue adding the epoxy until the crack is completely filled.

Note: Capping gel estimates are based on a cap thickness of 3/16" and a 1-inch width.

Note: The above chart is an approximate and may vary depending on waste, concrete and user technique.
