CPD - High Pressure Epoxy Injection

Lily offers four different types of adapters for porting: surface mounting, socket mounting, corner mounting, and insertion. All are tough virgin nylon that easily withstands injection pressures of over 700 psi. Nylon was also selected because the adhesion of epoxies to nylon is much greater than to polyethylene and most other plastics. This adhesion assures much stronger anchoring to the concrete.

	Injecti-Port I (P-235) & Setting Tool (P-317) The Injecti-Port I fits a 1/2” diameter socket. It is used when a surface is too irregular to allow the use of a surface mounted adapter, or when a socket must be drilled to penetrate beneath contaminates that prevent penetration from a surface adapter. The Injecti Port I withstands injection pressures of 1,300 psi.and for this reason is frequently used to inject polyurethane resins in 1/2” diameter holes. The Setting Tool (P-317) is used to drive the adapter into its socket, setting it so tightly that no epoxy paste is needed to secure it.

	Injecti-Port II (P-375) & Setting Tool (M-260) The Injecti-Port II adapter is bonded to a clean and sound concrete surface over the crack. It consists of a rigid stem rising from a perforated base. The same adhesive used to seal the crack is generally used to secure the adapter. A genrous dollop of the adhesive is applied to underside of the base, which is then impinged against the concrete surface. As the adapter is pressed into place, the adhesive oozes through the perforations. A tapered Setting Tool makes installation easy. The tapered tool holds the adapter while an epoxy paste is buttered to its underside. The tool is then positioned over the port location and the adapter is slid down the tool. When the adapter is pressed against the surface, adhesive oozes through the perforations. The tool is then removed as the adhesive is sticky enough to hold the adapter in place. Additional adhesive is applied over the base in conjunction with the application of the seal over the crack. The concrete surface will fail before a properly installed Injecti-Port II will loose bond.

	Nestler (P-380) The Nestler is a variation of the Injecti-Port II. It ports cracks and joints at interior corners between abutting elements such as walls and floors, or steel plates and concrete. If the crack is .100" (2.5mm), and not fully impacted with debris or calcification, it is probably feasible to port the crack by simply inserting a tube segment into the void. Such segments are much less expensive than other porting adapters and easier to install. Nylon tubing and connectors in various sizes are available from Lily Corporation.

	Crimp-It (P-316) & Cap-It (P-226) Cap-Its and Crimp-Its are used to seal off a port to prevent the injected resin from draining before it has cured. The Crimp-It, a thin metal sleeve, is slipped over the adapter stem before the resin connection is made. Following injection, and before disconnecting from the stem, the crimp is crushed with sharp pliers to close off any drainage following disconnection. The Cap-It is a plastic cap that fits snugly over the adapter stem. It is used to stem resin leakage from remote ports during injection.
	The Cap-It is a plastic cap that fits snugly over the adapter stem. It is used to stem resin leakage from remote ports during injection. It is easily removed to allow subsequent injection of the port.

	Connect-It (P-228) The Connect-It is a reusable connector that fits all of the Lily porting adapters and the resin supply tubing. It brings all of the Lily Connections together. A 1,500 psi connection is made when a tube segment or stem is inserted into the fitting. The fitting releases when its collar is squeezed against its body. The seal within the Connect-it is a special polymer that withstands cleaning solvents such as MEK and Acetone.

	Shut-Off Cock (P-233) This valve controls the flow of resin at each of the ports. The light weight is easily supported by the porting adapters, and the long handle provides great leverage when wearing gloves or when things get sticky.

	Nylon Tubing (P-134) The high burst strength (1,000 psi at 72° F.), 7/8” bend radius, resistance to nearly all solvents and chemicals, and Connect-it compatibility make this translucent tubing perfect for injection resin dispensing. It is available by the foot or in 250’ reels.

	Manifolds (A-270) & (A-280) These manifolds manage the plumbing for the injection of numerous ports simultaneously. The A-270 is a brass cross fitted with four Connect-Its. It splits the flow from a single line into three separate leads. The A-280 is similar, except that it is uses a 1/8” npt male pipe fitting at one outlet. The pipe connection fits the mixer, leaving three separate leads for connection directly to ports or to MR-3 manifolds for additional leads.

	Jiffy Mixing Paddles (P-754) & (P-237) For thorough mixing of the seal epoxy, use the Jiffy Mixer. The Jiffy is stainless steel, welded, and recommended by resin manufacturers. Use the 1 1/4” diameter for small batches, and the 2 3/8” diameter for larger batches. Both fit a 3/8” drill chuck.

	Vacuum Drilling Sockets must often be drilled to port delaminations or cracks so tightly packed with dirt that they cannot be injected from the surface. If conventional masonry bits are used to drill a porting socket, debris from the process is likely to be impacted into the void, obstructing the flow of the resin. Lily-built Hydro-Vac Drilling Assemblies avoid impaction by evacuating the drilling debris as it is generated. Vacuum or water flushing are used for the purpose. Both techniques use hollow carbide spade bits. Water is introduced to flush the debris from the hole in hydro drilling, and a vacuum is created to evacuate the debris by suction. If the concrete is dry, and the fault is .010” in width or greater, vacuum is preferred over hydro simply because it is a dry process. And besides, production is increased when drilling into slabs because debris that would otherwise accumulate and cushion the impact of the bit is quickly removed. A plastic swivel (P-405), 1/2” duralene tube segment (P-412), and a 2” diameter vacuum socket adapter (P-410) are used to transmit the vacuum to the bit. The Hydro-Vac Adapter (M-407) adapts the bit to any SDS drill. A quality industrial shop vac is recommended for the best performance. The drills are sturdy, and the carbide is of the best quality. They can be re-sharpened frequently. Although 1/2” x 4” usable bits (P-400) are most popular, lengths of up to 22” are available in 1/2” and some larger diameters. Smaller diameter bits are also available. When ordering, specify the diameter and the usable bit length required. If the concrete is damp, the hydro feature works well. Water is introduced through supple nylon tubing connected to a Delrin swivel. The water flushes the debris from the socket as it is generated. The hydro system is very thorough, keeping fine hairline fissures free of impacted debris. Caution must be used, and precautions must be taken when hydro drilling overhead with an electric drill in order to avoid shock.

	Seal Knife (P-493) Eureka! At last! We have found the perfect tool for tedious injection set-up. Use this stainless steel knife to effortlessly apply and shape the seal, lay a smooth cove around the porting adapters, and massage the capping material into wide voids and rough surfaces.
