Packer Materials & Types
Mechanical injection packers and injection ports are the gateway to successful injection. There are two primary categories of packers available. Insertable mechanical packers and surface mounted ports. SealBoss mechanical packers for grouting are made from steel, brass, aluminum, zinc, various metal alloys and plastic. There are important differences in design and functionality for a variety of products, substrates and objectives. Contractor preferences and comfort levels are also a deciding factor.
Premium mechanical packers feature a rubber sleeve with a threaded shaft. As the threaded shaft is tightened, the rubber sleeve is compressed, creating a compression seal inside the drill hole. A medium soft, ‘made to stick’ rubber that evenly expands diameter while compressed provides the best grip and highest possible injection pressures.
Steel
SealBoss offers many heavy-duty steel crack injection packer variations. Steel offers the most strength and good resistance to oxidizing components found in acrylate/acrylic gels. SealBoss offers a wide variety of steel packers to suit all injection needs. Most packers are equipped with a rubber sleeve, some have a larger washer on the top of the packer to assist in the installation.
Brass , Aluminum, Zinc
Brass, aluminum & zinc packers are economical alternatives to steel packers with similar functionality. The overall strength is lower than steel, brass, zinc and aluminum packers bodies are softer. In some designs, the shaft can be broken off by hammer after injection thus leaving a flush surface. This is an advantage if removal of packer prior to patching is not specified.
Plastic
SealBoss Plastic packers come in many versions. Some permit low resistance, high volume product flow and very quick installation.
Zerk Fitting or Button Head / Button Top
Packers are often equipped with either a zerk fitting or a button head as connective mechanism. The zerk type is most commonly used. It easily connects and disconnects and works with medium to high injection pressures. The button head type can be of advantage in high volume applications and it offers a superior connection which is helpful for single operator injection, over head and large applications.
The SealBoss 5/8” (16mm) Button Head packer offers high volume flow with a button head (button top) coupler to minimize leakage. Insert the plastic sleeve in the drill hole and thread the plastic packer into the sleeve for a compression fit via the hex button head. Anti return valve: A steel ball placed in the shaft of the packer prevents product back-flow.
Hammer-In / Bang-In
The SealBoss Hammer-In port (Bang In Packer) is 3/8” (10mm) or 1/2” (13mm). The ports are inserted into the drill hole with the tap of a hammer. These packers do away with the sleeve and compression sleeve mechanism as the plastic body of the packer itself creates a compression seal. The packers are set very quickly increasing productivity on the job site. Due to the lower friction fit, injection pressures are limited with this packer type.
Diameter, Length, Valves
Diameter
Various factors including the volume targeted for pumping, the depth of drilling, intended injection pressures, as well as aesthetic and other criteria, influence the selection of the packer size. Packers, designed for placement into pre-bored holes in materials such as concrete or rock, are selected to match the diameter off the drill holes.
As a rule, and in addition to the packer material, a larger mechanical packer diameter permits higher injection pressures. 5/8” (16mm), ½” (13mm), 3/8” (10mm) and 1/4” (6mm) are most common diameters for man made structures such as concrete substrates and seem to be the best compromise in strength and size and can be called a standard.
Larger diameters are mostly utilized in rock and other natural structures as found in tunnel and mining applications.
Caution: Packers and ports can exit the drill hole at high velocities under pressure. Correctly installed packers of the right dimensions will minimize this probability. In general, larger diameter packers prevent blow-out better than smaller packers.
The size of the drill hole equals the diameter of the packer. We discuss diameters and drilling angles and techniques in detail in our 1-2-3 at 45 Degree Crack Injection Guideline.
Length
The shaft of the mechanical packer needs to be embedded sufficiently deep within the drilled hole to establish an effective compression seal in the substrate. This depth also prevents spalling of the substrate during the installation and injection processes. For more fragile substrates or deteriorated concrete, we recommend using longer packers ranging from 4″ to 6″ (10-15 cm).
During the injection phase, the drilled hole serves as a conduit for the injected product. In instances where the contractor needs to bridge a substrate gap, a longer shaft length can be beneficial. To accommodate such scenarios, SealBoss offers specially designed packers with extended lengths, enabling the accurate delivery of the material to a specific location within the substrate.
Top Mounted Valve Placement
Two types of top-mounted valves are commonly used: zerk-valves and button-head (also known as button-top) valves. Of the two, button-head valves provide a more reliable connection with the least amount of leakage. Certain top-mounted zerk valves are supplied separately, which allows for the observation of injection grout’s port-to-port grout travel during the injection procedure. As soon as the material starts leaking from the succeeding packer(s), the contractor promptly installs the valve.
Bottom Mounted Valve Placement
Valves installed at the bottom or on the stem enable the removal of the packer’s top section shortly after injection, while maintaining the seal of the drilled holes. This arrangement facilitates the patching of the hole with the remaining part of the packer still embedded in the substrate. As a general guideline, packers should not be removed until the injected product has fully cured to ensure the most effective seal.
Surface Ports
Surface ports, which are often utilized for epoxy injection, provide a surface-mounted alternative to packers. They are ideal for situations requiring lower injection pressures or when drilling into the substrate is unfeasible.
These ports are either glued directly to the surface or positioned within a drilled hole. Many of them feature an open or valve-free design to accommodate quick-release connectors, offering a multiple port injection solution. Generally, surface ports come with caps to hinder epoxy backflow, ensuring a clean and efficient injection process.
For applications requiring a firm fit under higher injection pressures, surface ports with zerk fittings are also available. In addition to these, we offer corner ports, specifically designed for installation in 90-degree construction corners.
Conclusion
In summary, we typically advise starting with the 1/2″ (13mm) mechanical packers when determining the most suitable packer for your project.
Steel packers, possessing superior strength, are the go-to choice for very high injection pressures. However, based on economical factors, budget, and site-specific conditions, they may be more robust than necessary.
A larger packer diameter enhances the packer’s grip within the drilled hole, which is advantageous when dealing with extremely high injection pressures. Best practice dictates to always have larger diameter packers readily available, particularly for scenarios when drill holes inadvertently exceed the planned size.
For steep angle drilling, deteriorated concrete, uneven surfaces, and very high injection pressures, we strongly recommend longer packer sizes.
If your project requires a high product flow at lower pressures, the 5/8″ button head packers consistently deliver excellent results. For low-pressure scenarios in high-quality concrete, the 3/8″ Hammer-In packer is an ideal choice, though precise, round drill holes are crucial for a secure fit.
It’s essential to remember the criticality of a robust and reliable fit of the packers for the technician’s safety and the overall success of the injection work.
For specialized applications, we offer a range of modified packer and port designs. These include surface ports equipped with a zerk fitting for the use of single-component injection systems for smaller epoxy and polyurethane jobs, Injection Screws tailored for the SealBoss Injection Tube Systems for cold joints, and other specialized packers.
