The 1/2″ (13mm) diameter mechanical injection packer is often a reliable starting point for most projects. Steel packers are ideal for very high injection pressures, though economical considerations may favor alternatives like aluminum, brass, or zinc for a variation of scenarios including jobsite conditions and budget.

Larger diameter injection packer can reduce blow-out risks, while longer packers are recommended for angled drilling and degraded substrates.

High-flow applications at lower pressures may benefit from the 5/8″ button-head packers, while the 3/8″ Hammer-In packers could be suited to low-pressure work in high-quality concrete.

SealBoss offers a diverse range of packers and ports, including surface ports with zerk fittings for smaller epoxy and polyurethane jobs and injection screws for cold joint applications. Ensuring a secure fit and selecting the appropriate packer type is crucial for technician safety and successful injection results.

Injection Packers for Crack, Water Stop and Leak Sealing Injections

SealBoss injection packers connect the injection equipment (applicator and injection pump) with the structural substrate to serve as the port of entry – or filler neck – for a large variety of injection resins and chemical grouts into concrete mediums.

Our Packers are made from a various metals including steel, brass, zinc, aluminum / aluminium or plastic. Packers are typically equipped with either a zerk fitting or button head fitting for easy and secure connection to the applicator. The button head type offers the most secure connection in overhead, high pressure and high volume appplications.

Conditions of the jobsite, environment and material determine the type, material, and build of packer, in order to achieve the best injection results. SealBoss provides a very large selection of injection packers to meet all professional needs.

Injection Packers – Installation Types

Based on injection requirements and injection products to be used, we distinguish between borehole packers and surface mount packers, also known as surface ports.

Cylinder shaped, borehole type injection packers are typically used for high pressure injection with polyurethane bases, water stop and leak-seal resins and injection foams.

Borehole style packers work very well in wet and otherwise demanding environments, such as deteriorating concrete substrates.

We further differentiate between mechanical packers with a tighten-down and screw-in mechanism, and hammer-in technique packers.

The seal of the aforementioned packers is achieved by friction between the packer body in the drill hole and the surrounding substrate.

Surface mounted ports are mostly used for structural epoxy injection where a non-destructive injection process – no drill holes allowed procedure – is specified.

Surface mounted packers or surface ports are glued to the surface of the substrate and rely on the bond strength of the adhesive, such as SealBoss 4500 epoxy paste adhesive. Surface port placement is best performed on a dry substrate and can be difficult in wet environments with active water leaks.

Understanding the Advantages of Steel Injection Packers

SealBoss® Steel Injection Packers deliver superior performance in high-pressure injection applications. These mechanically engineered packers are designed to endure considerable force, making them ideal for demanding crack injection scenarios where high injection pressures are needed and reliability is paramount.

As the threaded shaft of the packer is adjusted, the rubber base experiences compression, resulting in a robust seal within the drilled hole. Owing to the exceptional strength of steel, these packers can withstand greater tightening forces. This capability enhances the friction between the expanded rubber sleeve and the concrete substrate, ensuring a secure seal.

Decoding the Concept: Port to Port Travel of Resin

The term ‘Port to Port Travel of Resin’ refers to the observable movement of the injected product from its point of origin to the subsequent packer. The SealBoss steel injection packer is designed with a removable fitting that enables the user to monitor this progression, ensuring precise and controlled application of the injection material.

Clarifying Standard Zerk Fittings versus Low Pressure Zerk Fittings

You may be familiar with standard zerk fittings, but what about low pressure zerk fittings? These specialized fittings are engineered for applications where the injection pressures are limited by the dispensing or pumping unit. A unique feature of these fittings is the presence of an anti-return ball valve devoid of a spring. This design minimizes the pressure required to open the valve, allowing the injection material to enter the packer with negligible resistance.

It’s noteworthy that SealBoss HOT SHOT Cartridges are compatible with Steel Injection Packers that are equipped with Low Pressure Zerk Fittings. For a more detailed understanding, refer to this informative video that demonstrates the use of the adapter.

Switching from Zerk Fitting to Button Head Fitting

SealBoss S-Type steel packers offer the flexibility to switch from zerk fitting to button head fitting, allowing usage with slide couplers. This versatile feature enables the use of both styles on the job site without necessitating different packer styles. Packers can be ordered with either fitting, based on the specific requirements of the project.

Each fitting incorporates an anti-return ball valve that opens under pressure, facilitating the flow of chemical grouts. Once the pressure is relieved, the ball valve closes, effectively preventing the backflow of the injection resin out of the drilled hole.

For more details on the zerk and buttonhead fittings and corresponding couplers, please refer to the conversion page.

Injection Packer Spacing / Placement

Optimizing Injection Packer Spacing and Placement in Leak-Seal Crack Injection

Injection Packer Spacing

Determining Mechanical Injection Packer Spacing Based on Site Conditions and Product Properties

In the context of leak-seal crack injection, the spacing of mechanical injection packers, also referred to as port spacing, necessitates careful consideration of various site conditions, such as crack width, substrate thickness, water flow, and product properties.

For numerous applications, an initial spacing range of 8 inches (20 cm) to 1 foot (30 cm) on-center is a suitable starting point. However, the presence of hairline cracks calls for tighter spacing, as the limited product dispersion hampers its ability to traverse extensive distances. Consequently, narrower cracks demand closer packer spacing.

Injection Packer Placement

Employing Staggered Injection Packer Placement for Enhanced Crack Intersection and Reduced Concrete Damage

To optimize the efficacy of leak-seal crack injection, contractors should, whenever feasible, employ a staggered injection packer placement strategy.

This entails alternating drill holes to the left and right of the crack and drilling at a 45-degree angle towards the crack, thereby creating a stitch grouting pattern.

Utilizing this technique increases the desired probability of intersecting the crack during drilling and diminishes the likelihood of inducing additional cracking or spalling in the concrete throughout packer installation or the high-pressure injection process.

It is generally advised to initiate the injection process at the lowest point and proceed in an upward direction.

How to Space Injection Packers Correctly – Mechanical Packer Placement Insights

This article is an excerpt from the SealBoss Podcast discussing Elevator Pit Repair with Chemical Grouts, hosted by Chris Coderre, featuring Jim Andrews of American Restore. Jim has over 30 years of experience in the chemical grout industry. If you’d rather listen, an audio version of the podcast is posted at the bottom of the article.

Chris Coderre: In relation to the packers — spacing of the Packers — technically speaking, with curtains and hydrophilics and hydrophobics, specifically to Packers, what do you see as the range, what have your experiences lead you to believe in terms of [spacing] what you go with on these elevator pits.

Jim Andrews: Well, that’s kind of a controversial question Chris, because you know, you don’t really know what’s going to happen. Even if you take a core, even if you run GPR [Ground Penetrating Radar] and you see you got a good dense mass — whatever the section is, however the section is built — you really don’t know what flow is going to be like until you’re hooked up and you are pumping.

And, as you know, you have to be sensitive to the owners wallet and a big part of this business, a big part of this work is labor. And why would you drill 50 holes in a pit when you might be able to accomplish the task with ten?

Chris Coderre: I love it.

Jim Andrews: We don’t go out there and drill a bunch of holes and set up a bunch of packers and then the guys start pumping and realize they could have they could have accomplished the task with a fraction of of that effort.

So what our guys will do — and we’re doing this right now — we’ve got two or three jobs and I was on one yesterday that we’re doing, where I said ‘gee man’, you guys have really drilled a lot of holes here and they said, … , we’re actually consolidating honeycombed concrete walls, and we’ve just want to get in the flow.

We weren’t getting the flow and so we had to put more holes in but they started with a you know, 12 inch, 16 inch, 18 inch spacing but at the end of the day they had to get down to 4 to 6 inches to get proper flow consolidation.

So on this kind of grouting, if you can get the proper grout at the proper viscosity behind the mass and you have the right pump and you can pressurize it — you can push grout, Chris.

I mean, you know, we were on a job together years ago in San Jose where we were pushing grout over a hundred feet behind improperly consolidated water stops, so we were pushing grout a hundred feet through one hole one packer. And even though the owner had to spend some money to fix the problem, we saved him a ton of money because we weren’t in there drilling all these holes.

So, you know, any time I see a specification and they’ve got this very uniform detail of where they want the packers set that tells me that the guy doesn’t really know what he’s doing and it also tells me he doesn’t have any respect for the owners wallet, because, you know, drilling holes through six or eight or 12 inches of concrete … — we spend a lot of money on packers. We spend a lot more money on drills, drill bits and hammer drills.

I mean does that answer the question? You can have four pits on in one building and they you could have four different processes to fix the problem. I mean water’s coming in, but you might have good consolidation soil mass behind one, not too good behind some others.

So anyway, it really boils down to the knowledge and experience of the guys doing the work.
