When shopping for alcohol-based hand sanitizers and alcohol-based surface cleaners, you should pay close attention to the type of alcohol listed in the ingredients.  Isopropyl alcohol offers a couple of key advantages over ethanol alcohol.   Let's review them...

Isopropyl is Gentler on Your Skin Than Ethanol

According to this article from the National Center for Biotechnology Information, "Ethanol use is associated with skin irritation or contact dermatitis...", among other concerns.

Ethanol Tends to Have a Harsher Smell

The harsh smell of ethanol intended for topical use is often caused by the "denaturing" treatment during the manufacturing process - in which harsh chemicals are added to make it un-drinkable.  Isopropyl, on the other hand, is not a drinkable alcohol in the first place.

Isopropyl is a Key Ingredient in Sanitizers & Cleaners

Due to the two concerns outlined above, we choose to manufacture Alchemy-Spetec hand sanitizer and surface cleaner with isopropyl alcohol because it's a healthier ingredient.  We don't cut corners with our industry-standard polyurethane concrete repair products - and we won't cut corners with the sanitizers either.  Rest assured.

The AP Jack Attack System provides leverage for positioning small to medium slabs into place while lifting or stabilizing with polyurethane. Easy for one person to operate. Triangular steel frame.

Even with the largest polyurethane rigs on the market, manipulating small slabs can be very tedious. It would be nice if all slabs settled evenly but that is rarely the case. Often slabs settle unevenly, making it nearly impossible to lift and rotate back into place with foam alone. It will lift for sure but it won’t rotate back into place.

For these small to medium slabs we recommend the Jack Attack System. This super-easy leverage system can be attached to a slab with concrete screw-in anchors. Then the integrated 8000 lb (3628.74 kg) jack can apply the leverage necessary to make the slab rotate back into place while the lifting process takes place. It is good practice to leave the slab 1/8”-1/4” (3-6mm) under-level to allow the foam to create optimal strength as it performs the final lift to level. It makes even the most troublesome sidewalk slab a piece of cake and you will use less foam as well.

This photo is from a job in which the front porch settled away from the home causing columns to separate from the roof line. On one end the slab had actually cracked in two and was settled away from the home as well as parallel to the home. You can see the triangle-shaped Jack Attack System holding the slab in place as foam is injected underneath.

Chemical grouts have an amazingly diverse range of properties. This makes them incredibly useful for all types of waterproofing, soil modification, and structural repairs. This wide range of characteristics means that there is no one size fits all grout out there. But I get ahead of myself. Before one can select a chemical grout for a repair it is necessary to understand not only the asset to be repaired but also how and why it is failing and/or leaking. There are numerous methodologies that can be utilized to determine what is going on, but before one can start the troubleshooting one needs to understand the structure's design.

This is why I love articles like this one from PileBuck.com. It gives a good overview of seawalls and bulkheads. These structures are often the frontline in our war against erosion and thus require periodic maintenance. We at Alchemy-Spetec are committed to providing cost-effective, high-quality grouts tailored to the precise needs of the project. We know that a quality grout is just the beginning and we follow-through with the most experienced technical support in the industry. Enjoy the article...

Along bluffs and coastal shorelines, various structures are often necessary to protect beaches from wave action, or to retain fill or in situ soil.  There are three primary structure types that can be utilized to accomplish these goals, including protective materials laid on slopes, known as revetments, and vertical structures, which are classified as either seawalls or bulkheads.

Revetments are typically constructed of stone or other durable materials to provide protection for designated slopes.  They are built with an armor layer, a filter layer or layers, and toe protection.  The armor layer can consist of interlocking structural elements designed to form a geometric pattern, or a random mass or stone or concrete rubble.  Next, a filter layer will ensure drainage and protection of the underlying soil.  Finally, toe protection will offer stability against undermining at the base of the revetment.

While bulkheads and seawalls are both types of vertical structures used to protect coasts, they have different purposes.  Bulkheads are used to retain or prevent the sliding of land, with protection of the upland area from wave action as a secondary consideration.  In contrast, the primary purpose of seawalls is to intercept waves.  Bulkheads can be cantilevered, anchored, or gravity structures, with their use limited to areas where wave action can be resisted by the types of materials used in these respective designs (such as sheet piling or rock-filled timber cribs).  For areas where intense wave action exists, massive concrete seawalls are the more appropriate choice, with either a vertical, concave, or stepped seaward face.

This article is an excerpt from Episode 6 of Alchemy-Spetec's podcast The Injection Connection, featuring industry veteran Jack Whitworth. The Injection Connection is hosted by Jim Spiegel: Vice President of Alchemy-Spetec and Board Member at the International Concrete Repair Institute. (If you'd rather listen, an audio version of this exchange is posted at the bottom of the article.)

Jim Spiegel: I think you and I have talked at some industry events and some networking events about the fact that it really serves us, even though we're competitors, to have a unified message of how work is done. Having the same recommendations, so to speak, would do all of us more of a service to work together than to try to work apart. Not everyone has the field reps that really know what they're talking about. I know there are a lot of great chemical grouting people out there, but you could probably count on both hands the real good ones. I think you would probably agree with that. We need to work together and educate as well as we can on that grouting committee.

Jack Whitworth: Correct.

Jim: And those meetings are great because it's all the heads of the industry so to speak trying to work towards a unified goal. But of the things we struggle with in that committee is the whole marketing side of things. You have your SLVs, your LVs, you have your semi-rigid, your semi-flex, there are all these ways you can skin a product. How do you view that as far as how some people might refer to as an SLV versus an LV? You know how it is, different companies will just say, “Oh yeah, you need an SLV, here you go.”  What's your opinion on that as far as nomenclature and some of the confusion?

Jack: I think a lot of the confusion starts with an earlier comment you made: “if all of the grout manufacturers could work together”. One of the biggest issues we have is the ASTM guidelines. It not only affects the commercial industrial side… If they're going in the tunnel projects, there's just this unknown of what can be utilized under certain conditions. It’s the message that we have to send, a clear concise message to the engineering and the design community and the contractors. One of the most important things that I like to strive on is - what are the points you need to consider in selecting a grout? As you know, there's no silver bullet to stop water infiltration or stabilize the soil. I think that the more education there is, and the more fluid we all are together in spreading that communication, the more we’re actually going to help the business grow. We look at where new buildings are being built, they might be old moss lands or water bearing areas where they've filled it in. There are areas and locations where we never imagined a building would sit. These are, as you know, great opportunities for us in the chemical grouting side of things. We see a lot of misadvised materials, I guess you would say, being utilized. I believe in what we call an assessing type of practice to where there are a lot of questions that need to be asked before we throw an answer out like, “use an LV or SLV.” It could consist of questions such as - what's the method that we can use to actually get the grout there long enough to set up? What are the substrate types and conditions because, as you know, all substrate types could require a different type of grout. What is the pH of the water source? What's the nature of the crack? Is it a moving crack? Those are going to be things that we need to have answers for. And things like - what's your water flow in the source of your water? Those become very important questions. And I think how we've hurt the industry a lot of times is that people have lived by the silver bullet theory rather than trying to spread a good consistent message.

Jim: Yeah, I would agree completely.

(If you'd rather listen, an audio version of this exchange is posted at the bottom of the article.)

Jim Spiegel: Obviously, you have a ton of experience, so I’d like to get some insights from you. What do you think are some of the strengths of the chemical grouting industry? What's kept you in it for 26 years? What do you like about the industry and why do you think it has such a strong future?

Jack Whitworth: I like the industry because it's challenging, no job typically is the same. You have to be quick on your toes, you have to be able to react to emergencies and that also ties into the fact that chemical grouts will always be necessary - but the job never gets boring. Plus, you get to see a lot of locations and areas that the general public (or probably at least 75 percent of the population) doesn't even know exist. It's exciting to get out there and be a solution provider. That's probably what really keeps me interested in it the most.

Jim: Yeah, I agree. That's a good point that the places that the chemical grouting industry takes you is just unbelievable - walking the gallery of a dam or something like that, it's a place you would otherwise never know existed. There are some really interesting projects out there. One of the things that is a concern, is the fact that no kid will say, “I want to be a sales professional for chemical grouts when I grow up.” How do you get young talent interested in chemical grouting?

Jack: Typically, you almost have to be lucky to run into somebody that has interest in it because it is the unknown that's out there. There is no magic because if we went to college fairs and different things like that, they’d think we were crazy because it's not that understood. But I think where we find most of our opportunities for representatives is typically in the field. That could be a contractor, that could be a distributor. We typically have a good knowledge of what their work habits are and really they have some fairly decent knowledge of chemical grouts because if you take a distributor salesman, for instance, you might find a guy that's selling a ton within one location. I want to meet that guy. I want to know why he's finding these opportunities and those are people we try to look out for.

AP Oakum is an oil-free dry jute rope which can be used dry or soaked with Spetec PUR GT500, Spetec PUR F400 or any other Spetec water-reactive resin to seal leaks in concrete structures. The oakum rope works well dry to drive into cracks as a temporary seal to allow injected resin time to cure without washing out. Here’s an overview of the installation process:

Preliminary Analysis

Determine if the large crack or joint is structural or cosmetic. If deemed structural, consult an appropriate engineer. Oakum is typically utilized in conjunction with water-reactive chemical grouts in leak-sealing applications. Void filling of these spaces can also be achieved through similar application techniques and appropriate product selection.

Preparation of Substrate

Remove all existing sealant, debris, or contamination of any kind. In large openings, inspect for loose concrete or anything that would prevent insertion of oakum into the desired depth and location.

Preparation of Product

Firstly, cut oakum into desired lengths and segments. Pre-mix hydrophobic or hydrophilic chemical grouts per manufacturer recommendation in a separate container taking note of working times and reaction times. Once the material is mixed, quickly, and fully soak the Oakum in the mixed chemical grout. Place the saturated oakum to the desired location.

Preparation of Personal Protection Equipment

Oakum is typically manually installed. Be sure to wear full hands, arm, face, and eye covering at
all times. Chemical grout can drip/spill cover anything with which it comes in contact.

Application of Oakum

1. Clean the surfaces to which the oakum will be applied. Wet the surfaces down if necessary, to react with the resin.
2. If necessary, cut the oakum into appropriate lengths.
3. Place oakum in a clean container (5 gallon/18.9 liter pail or plastic bag) and saturate with resin. Allow time for the resin to soak into the oakum.
4. Using gloved hands, pull a section of oakum through a loose set to wring excess resin from the oakum.
5. Optional Step: Dip the oakum into a pail of water to begin the reaction process. This will begin the reaction process of the resin. This step causes the resin to begin to expand.
6. Pack oakum into the joint, crack, or other defect using a screwdriver, wooden dowel, or other mechanical device sized appropriately for the joint, crack or defect.
7. After the resin has cured you may inject additional resin through a grout needle directly through the oakum or by drilling holes through the concrete behind the oakum.
8. Allow the material to cure overnight before attempting to trim the excess foam.

Brief Video Clip

Here's a brief video, taken from my trusty Grout Geek Helmet Cam, of me packing oakum into a gushing leak.

This post is part of the Alchemy-Spetec Contractor Lens series, featuring views, news & case studies written by our customers.  This article, written by Robin Smith of Dalinghaus Construction, contrasts the methods of polyurethane slab lifting vs mudjacking.  If you're an Alchemy-Spetec customer and you'd like to discuss writing content for our blog, please send an email to marketing@alchemy-spetec today!

Have a sinking slab you need to lift? Here at Dalinghaus we offer Polyurethane Slab Leveling, but we often get calls from customers asking for something called “Mudjacking”. If you follow us online, you have gotten an opportunity to learn a lot about Poly, but might not know anything about mudjacking. We are going to break down some of the basic differences between them! You do have options! So let’s take a look at Poly VS Mudjacking, and see what looks better to you.

What is Mudjacking???

Mudjacking is the process of lifting a building, driveway, or any slab of concrete by pumping a mixture of concrete and water (known as mud to people who work with it) underneath a sunken slab raise it back to a level or a predetermined lift. The process of mudjacking settled concrete has been around for over 60 years, and as such, the issues with the process have been well documented. Some of those issues include:

• Weight Of Material: The weight of the “mud” material can be as much as 100lbs per cubic foot! (Compare that to Polyurethane that comes in at about 2-4lbs per cubic foot!) Typically a slab starts sinking in the first place because the soil around it has been compromised. The added weight of the concrete can cause further settlement. Why fix a problem with something that potentially adds to the problem?
• Big Holes In Your Concrete: Mudjacking requires drilling a 2-3” hole through your slab to pump the thick material through. The number of holes needed is dependant upon the condition of the concrete. (Compare that to Poly that only requires a ⅝” hole to inject material!) These holes then need to be patched, and they tend to stick out like a sore thumb. 
• Curing Time: The concrete that is pumped under the slab isn’t exposed to the sun, it takes longer to cure. It can take days to a week to dry! (Our Polyurethane sets up in just seconds! Check out this project that we completed at the Orange County Transit Authority. Our technology was able to keep the bus schedule on track without missing a beat!)

When it comes to Poly VS Mudjacking, Poly makes WAY more sense to us! If you want to learn more about how we can help you, give us a call!
