As we stated in a previous blog post, Lifting Slabs in Cold Weather, there are plenty of jobs that need to be done in the winter. This is just as true for sealing leaks as it is for slab lifting. So let's take a look at those cold weather leak seal markets. We'll also review some special considerations for conditioning leak seal material and equipment. Then we’ll leave you with a few cold temperature leak seal application tips.

Cold Weather Markets

You have a variety of options for seeking jobs that are inside, out of the elements, during the winter months.  Hopefully these ideas will spark more brainstorming on your part. First up we have tunnels, both pedestrian and vehicle. Tunnels often leak, sometimes significantly enough to result in quite a big job. Aquariums are another possibility. As you can imagine, there are infinite potential leak problems in a structure holding that much water. Other possible large jobs could include mines and water treatment plants (which have plenty of interior spaces with potential leak issues). On the smaller side, there are utility vaults, lift stations, manholes and elevator pits.

If you’re still up for working outside during the winter months, you’re in luck because concrete contracts during colder weather. The contraction makes cracks open wider. Wider cracks make leaks more apparent to the property owner and make them easier to repair.

Conditioning Materials and Equipment

One important point to understand is that cold weather requires you to make an extra effort to keep your materials and equipment warm. Cold material reacts slower and gets thicker. Be sure to store your materials and equipment in a heated room the night before the job. When on the jobsite, there are many ways to keep everything warm. Use an enclosed vehicle, like a box truck, enclosed trailer or pickup truck with a camper top or bed cover. Keep as much material and equipment inside the vehicle as possible when working. Use a portable heater to maintain a warm temperature. You can also use electric pail heaters to keep your resin ready for action.

Remember that it won’t do you any good to heat the resin if you’re pumping it through cold equipment. The cold steel inside the pump and the cold hose will literally suck the heat out of the resin before it gets where it needs to be. This will increase the viscosity, making it harder to mix with the water and it will slow down the reaction dramatically. So don’t neglect the equipment side of the equation!

Cold Temperature Application Tips

If you’re using a product with an accelerator, you may need to use a faster accelerator or increase your percentage. Also, bring lots of oakum. You may have to use more if the cold temperature slows down the material or the contracted concrete has made the cracks wider.

If your job requires you to inject into a structure underwater (and the water’s cold), you can use a technique called twin streaming. In this approach, you hook two valves together in parallel fashion – then inject warm water along with the resin to kick start it reacting before hitting the cold water.

Conclusion

I hope this overview has helped spark some ideas on your part for finding leak seal work during the winter months. Just remember to keep your materials and equipment conditioned and you should be fine. Have more questions about polyurethane leak seal in cold weather? Call us at 404-618-0438.

Contrary to popular opinion, as a contractor, you don’t have to put up your equipment and rigs due to cold weather. There are many jobs to be done and many ways to keep your material conditioned. Use this season to your advantage and gain valuable business.

Cold Weather Markets

Seasonal attractions such as theme parks are a great place to start looking for winter work. Many of these parks (the ones that aren’t in Orlando) shut down for the winter and this is the time they do maintenance and repairs. Think of all the concrete lifting and leveling that can be done.

Factories can be less active in the winter months with production slowing down in many industries. This is a good time for them to do maintenance and floor repairs as well.

Warehouses typically operate year round, so there is always work available. Warehouse floors are used and abused on a daily basis and will sooner or later need some form of repairs done to keep business running at a steady pace. In addition, many warehouses have dangerous voids beneath their floors that require repair.  

Exterior concrete slabs are still worth considering, even in the cold weather. These slabs experience the most wear and tear from the environment itself (think erosion) and daily traffic. You’ll need to lift concrete slabs before the ground freezes and only after your materials have been thoroughly conditioned.

Conditioning Materials

Your slab lifting equipment probably has built in heaters and a heated hose. Each brand and model of pump has different sized pre-heaters and different ∆T (∆ = Delta and T = Temperature). This sounds complicated, but is actually quite simple.  ∆T is simply the change in temperature.  Let’s say your material has been sitting in a cold trailer all night and the temperature has dropped to 40 degrees F. If the required temperature of your B side material is 120 degrees F, then your pump better be rated with a ∆T of at least 80 degrees. However, if your material is preconditioned to 70 degrees F, then your machine only has to be rated for a ∆T of 50 degrees. As I said, every machine is rated differently based on the size of the heaters. What is important to know is that there are limitations to how much heating your machine can do.

Keeping your materials conditioned in the winter months is a lot easier than it sounds. The main point is to keep your AP Lift products above 60 degrees at all times. Keeping the polyurethane at or above that temperature can be accomplished in a number of ways.

If you have an insulated rig, it should stay around 40 degrees warmer than outside temperatures. Most foam rigs have built in electric heaters that require an extension cord to a power outlet at the job site or at your facility for overnight storage. Alternately, you could buy an electric radiator heater. Other available heating devices include drum band heaters and heated drum mats (be careful not to scorch the polymers by turning band heaters up too high). For a more DIY approach, you could build a hot box around the material storage area in your rig.

Heat Sink

Another consideration when lifting cold slabs is the heat sink factor. AP Lift products come out of the gun hot and get even hotter as they react. However, cold concrete acts as a heat sink and sucks the energy out of the foam as it starts to react. This can slow down the reaction speed of the foam. If you are pumping into a void, it will have little effect because most of the foam is not in contact with the concrete. If you are trying to lift a slab with little void, it will have more of an effect because more of the foam is in contact with the cold concrete and cold soil. More volume = more energy.

Conclusion

Don’t let common preconceptions deter you from slab lifting in cold weather. As noted above, there is no need to shut down completely for the upcoming winter months if you don’t want to. Opportunities still exist and one of them may just be the job you’ve been looking for all year. There are many ways to keep your equipment and materials conditioned to efficiently work in lower temperatures. Have more questions about slab lifting in cold weather? Call us at 404-618-0438.

This article is an excerpt from Episode 9 of Alchemy-Spetec's podcast The Injection Connection, featuring Charlie Lerman "The Grout Geek". Charlie is Director of Technical Services - Leak Seal® Division at Alchemy-Spetec. 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 excerpt is posted at the bottom of the article.)

Charlie Lerman: I’m very honored and happy when people say, “You’re very passionate about this.” And I am. I do enjoy it. It’s a lot like a game to me. And you know I’m pushing 50 here and I still play video games. I’ve played video games all my life. And I just love the strategic element. Kind of like a chess game. I look at every grout job just like that. When I go out there, I know what my pieces do; what my product, what my pump, what my drill, I know what all those pieces can do. The thing is, the game is, that I can’t see into the wall or see into the substrate and know exactly what’s going on in there.

So I have to take my knowns and then rule out things that aren’t working or figure out why something is working. It’s a big game. And then, on the other side of that is I’m the hero. When you come out there and you help somebody with a project or something that they’re having trouble with and you’re successful, everybody is happy to see you, they’re buying you lunch. So, it’s a great thing because first off, it’s just mentally stimulating and you’re solving an issue the proper way. And then everybody is happy about it. So to me, it’s just a win-win all the way around with that.

The choice of a polyurethane material provider for your geotechnical contracting business is a critical decision with far-reaching consequences. In addition to top quality concrete and soil repair material, a premier provider will offer reliable high-performance equipment, rock-solid tech support, extensive training resources and even marketing assistance.

Polyurethane Materials

All polyurethane materials are not created equally. Make sure you ask around the industry to see which materials are the most reliable.

Characteristics of High-Quality Materials

• 100% virgin (do not contain recycled polyurethane).
• Easy on your reactor (does not create high-pressure that wears out your equipment).
• Unlikely to catch fire (yes, some sub-par materials out there will char or catch fire while setting up).
• Capable of bonding to concrete.
• Strong and durable after they set up.
• Approved for contact with potable (drinking) water after curing.

Rigs and Equipment

The quality of your geotech rig is not something you want to compromise on. A premier provider will offer state of the art rigs set ups, customized to fit your exact needs. You’ll want multiple door options (side door, choice of barn door vs ramp door), multiple power outlets and slide-out equipment options. These features allow for maximum flexibility in all types of job situations. In addition, a well-insulated rig allows for operation in a wide variety of climates.

Your pumps, air compressors and slab lifting guns need to be reliable as well.

Characteristics of High-Quality Equipment

• Easy to use (not overly complicated).
• Easy to maintain (easy to clean, not a lot of complicated parts to replace all the time).
• Reliable, reputable brands.

Tech Support and Training Resources

A major differentiator separating serious material manufacturers from the rest is the availability of on-the-job technical support and service. A premier provider will offer field service to assist customers on challenging jobs. Phone support should readily available as well, with support techs ready to answer questions when you need the answers. You will also want to look for comprehensive training resources on material installation, equipment use and maintenance, and estimating/billing jobs. A good combination of online videos and articles, training literature and live events is the sign of a manufacturer dedicated to educating their customers.

Marketing Assistance

Look for a provider offering robust marketing assistance. Geotech contractors have many marketing needs, including website content (illustrations, photos, descriptive text), videos, vehicle sign design, advice on lead capture, etc. A manufacturer willing to go the extra mile in this department can help give you an edge of the competition in your market.

Do Your Own Research, Make Your Own Choices

Did we just describe Alchemy-Spetec in the paragraphs above? Of course we did. This is the Alchemy-Spetec blog after all. That being said, we encourage you to do your own research and contemplate your own needs in a material provider. Ask around in the industry. Seek out users of different brands and find out all you can about their experiences. If you think we missed anything in this article, let us know. We’d be happy to hear from you.

This article is an excerpt from Episode 8 of Alchemy-Spetec's podcast The Injection Connection, featuring Matt Chittick and Travis Germick, co-owners of Lift It Rite, LLC, a residential slab-lifting business. 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 watch the video clip of this exchange, it is posted at the bottom of the article.)

Jim Spiegel: If there's one thing that you guys, a piece of advice or some sage wisdom, as I know you guys are full of that as well as punch lines (laughter), what would you say to someone thinking about getting into the lifting business?

Travis Germick: If you're going to get into the industry, I would say get with Alchemy-Spetec and get some training. Hang out with those guys, come down and watch someone do the work. Get with a reputable company, come with us and work for a day or two and see what it's all about.

There's a lot of people that can definitely do this job but there's also a lot of people that could not do this job. There's a work ethic that goes with it. And I think with any spray foam or something like that, if it's insulation or whatever it is but there's a special ethic that has to go with it and special type of person it takes to get into this. But we absolutely love it. Every day, we get up, we're excited to do what we do because our customers’ minds are blown every time they see foam lifting concrete. And we feed off of that. I mean, they're over there like, “wow, that was cool” and I'm like, “I know, right?” That was really neat. We’re really psyched about it as well. There's a lot of times where Matt and I are high fiving each other because, that was a really cool job we just did.

That’s the only takeaway I have with it. I think it's a great industry to be in. I think it's a great service that we're offering and it's cool, too. It really is some neat stuff. What do you think, Matt?

Matt Chittick: I 100% agree. I would tell somebody you can learn all the ins and outs of it but until you get on the job sites and you see some things happen and you kind of roll with the punches, me and Travis, we have fun. If you have fun, it doesn't feel like you're working. And I would say have fun. You want to look for more good jobs than bad, but don't let the bad jobs bring down your attitude because your customers will feed off of your attitude. If you have a great positive attitude, those customers are going to have a great positive attitude. And if they have a great positive attitude, guess what, they love writing checks.

Jim: Yeah. I couldn't agree with you more that the attitude is such a big part of it. And then that starts when you get out of your truck, right?

Travis: Absolutely.

Jim: If you get out of your truck and you’re all smiles and having a good time with them, it just leads into a good experience. Not only do they feel like they trust you, but when things go wrong, they're more tolerant, I feel.

Matt: Yeah, absolutely. I would say because of our attitudes and things like that, we've been able to explain some things to customers and show them what happened here, what happened there and whatnot and they know that we're professional because that's the way we come across. We keep them involved in it, and when they see these things happen, I think they are a lot more tolerant and really accept some of the imperfections. That might be because getting concrete back to the original exact part or area whre it was might not always be what you can do. But if you talk about those expectations and you keep the customer informed and you're upbeat and positive, that's just going to transcend right to your customer and then everybody's okay and everybody's having a good day.

This article is an excerpt from Episode 7 of Alchemy-Spetec's podcast The Injection Connection, featuring concrete lifting marketing expert Ann Thaxton of ConcreteTitans.com. 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: As you know in the industry it's very expensive to get into this, just on the equipment side of things. You're looking at 50, 60, 70, even more - $100,000 perhaps depending on your rig setup.  So, one of the questions we get all the time is – “Okay, I'm going to invest in this equipment. What are you going to do for me and how do I get leads?” That's probably the number one question. For the customers that buy the equipment, their biggest problem we see as far as their success is their lack of marketing or advertising strategy. Say I'm Joe the builder and I want to get into this, and my first question is, “How do I start? Where do I even start with marketing, advertising and lead capture?”  Could you talk us through what solutions you may offer on that and any information on monthly budgets?

Ann Thaxton: We've found throughout the industry that for cost per lead, your cheapest cost per lead is digital advertising. Your most expensive cost per lead is TV. And everything else falls in between. Your average cost per lead with digital advertising runs between $40 and $50 per lead. TV runs around $200 to $250 per lead. Direct Mail runs about $150 per lead. Ideally, if you were a more mature company, you would do all of those because studies show that it takes anywhere between 12 and 18 touch points for somebody to convert to become a customer. If you're just starting out in the business, your cheapest cost per lead is digital advertising. But I wouldn't just stop there. If you have time on your hands and if you are able to, then print up some door hangers and hang them up around neighborhoods where you know they have some problems with their concrete. If you level concrete in one neighborhood, you hang door hangers on both sides of that house and across the street for sure. And you ask your customer if they would please refer people to you because referrals are really the gold standard here. Referrals are “free” cost per lead. So, once you get really mature as a company, you get so many referrals that it just becomes gravy on top. But to start out, I would think that you would do a lot of that pounding the pavement type of work to get your name out and then do some lead advertising. And I have different levels of service. From the start, from the starting service up to 4+ rig companies. And for a budget to start out, you can spend less than a thousand a month.

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

Jim Spiegel: A lot of your expertise is in social media and SEO. Do you offer support in that entire realm of marketing?

Ann Thaxton: I do. I pretty much am a mixed bag, but for home repair industries really the most effective channel of marketing is lead advertising. I'm a big proponent of lead advertising because you get a concrete return on your investment. You get a potential client’s name, phone number, email address and why they're contacting you - maybe their pool deck needs to be raised or they have a parking lot that needs to be leveled. That's what I really push the most with this industry is lead advertising. Not only that but I also really promote the lead nurturing process. So once you get your lead from lead advertising, you start a series of automated emails that go to those people maybe two to three weeks and it educates them on the industry. One of the big things, one of the big challenges of residential concrete lifting is a lot of people don't know that it's a thing. They don't realize that you can repair your concrete rather than replacing it at a fraction of the cost. I think that is a big part of why you need that sort of lead nurturing so people can start getting their brain around – okay, well, how does this work? How do you raise this concrete? And how long does it take? That sort of thing. So yes, I do search engine optimization, SEO, I do websites, I do email nurturing campaigns for leads, lead advertising, some sales training. I look at it as if you take a business that has maybe two rigs and they have two crew that are going out, you start them with the basic lead advertising email nurturing and hopefully you can get somebody on staff that is a customer service person that does nothing but call these leads the second they come in and it helps you build the business from there. A lot of the nurturing I do for the leads is not just emails, it’s occasional texts. It's consistent phone calling until we know if these people are going to convert or if they're not interested. That's what you’re trying to find out from these leads. So lead advertising all the way.

Jim: And are you heavily involved with the social media side of things?

Ann: I believe that you should post on your social media business pages. People do you go there occasionally but the algorithm with that is not what it used to be five years ago even because Facebook is now a public company. They want to make money. So they are not going to show your posts to the people that like your Facebook page unless you put some money behind it really. I do lead advertising on Facebook which is a great platform for educating people on concrete lifting in that it's a real home repair service. I believe in posting maybe a couple times a week but then I also really believe in lead advertising on social media. And then LinkedIn if you want to build your commercial business.

Jim: You're saying lead advertising and excuse my ignorance but essentially you’re talking about the lead capture side of it?

Ann: Yes. So, usually you need to offer something, like maybe a $50 off coupon, $100 off coupon. And they click through, in order to get that coupon, they have to give you their name and information.  Then you send the coupon pretty much immediately and call shortly after that. So that's how that works.
