It's time to revisit the idea of remaining profitable during the winter months, but where does one begin?

Engaging with Engineers and Consultants

Networking with engineers is a cornerstone for securing a consistent flow of projects. Engineers are usually involved in any sizable geotechnical or waterproofing project. From industrial settings to property management companies and hydroelectric plants, an engineering firm is almost always the first port of call for problem-solving.

Alchatek offers presentations designed for engineers that cover a range of polyurethane applications like leak sealing, soil stabilization, and concrete lifting. These presentations often qualify for continuing education credits, offering engineers added value. We prefer to collaborate with local contractors for these presentations, creating a link between suppliers, contractors, and engineers.

With diligent follow-up, such activities typically yield smaller-scale projects, which, when successfully completed, pave the way for larger undertakings. Engineers are the go-to professionals for property owners facing issues. If you establish yourself as a reliable, punctual, and skilled contractor, you are more likely to secure jobs without having to go through the bidding process.

Networking Through Professional Associations

A wealth of professional associations exists across various fields and trades. Becoming a member provides an excellent platform for networking and discovering new opportunities.

Take, for instance, your local chapter of BOMA (Building Owners and Managers Association), which represents the expansive commercial real estate industry. BOMA members are mainly property owners, facility managers, and building engineers—a perfect audience for discussions on topics like elevator pits, parking structures, and tripping hazards.

IFMA (International Facility Management Association) is another noteworthy association. While BOMA represents the "landlords," IFMA represents the "tenants," who are often the first to report issues. Presenting to IFMA allows you to inform facility managers about problem-solving polyurethane technologies.

Don't overlook ASCE (American Society of Civil Engineers) either. It's not just for engineers; they offer a category called Organization Partners for non-engineers. Your presentation here can also be facilitated by Alchatek.

Reaching Out to Government Agencies

Sometimes old-school techniques like making phone calls and doing online research are invaluable. Connecting with local municipalities and Departments of Transportation (DOTs) can give you insights into upcoming projects. Attend bid meetings to network with general contractors and engineers.

Don't ignore mass transit authorities in cities with train or subway systems. These authorities regularly release projects for bidding and have engineering departments that could benefit from your solutions in leak sealing and geotechnical applications.

The cold months are an opportunity if you're a contractor seeking winter work. Not only will these strategies help you find winter projects, but they will also positively impact your business all year round. Reach out to the Alchatek support team for guidance.

Contractors specializing in chemical grouting in the northern United States are often constrained by the seasons when it comes to outdoor soil stabilization and slab lifting tasks. However, with strategic planning, they can also find profitable avenues to keep busy during winter.

Winter Geotechnical Projects

• Warehouses and Distribution Centers: Interior slab lifting and void filling. Concrete floors and loading docks.
• Office and Retail Spaces: Interior concrete leveling.
• Infrastructure: Below the frost line where groundwater seepage impacts the density of soil and the stability of pavement.
• Agricultural Facilities: Slabs in structures like grain-drying bunkers.
• Commercial/Industrial Settings: Void filling and slab leveling in manufacturing plants and factories.

Expanding the Scope: Other Polyurethane Injection Applications

Winter also provides an opportune time to acquire new skills in areas like crack injection, slab undersealing, and curtain wall grouting. Cold weather conditions make concrete contract, widening cracks and joints, thus making them easier targets for injection work. Here are additional applications requiring attention:

• Subterranean Parking Garages: Leaks through cracks, expansion joints, and cold joints can be treated with specialized leak seal resins.
• Elevator Shafts: Particularly in areas with high water tables, elevator pits are prone to leaks.
• Tunnels: Whether for pedestrians, vehicles, or mass transit, tunnels often face water seepage issues, solvable via polyurethane grout.
• Dams: Despite their massive structure, dams are not immune to leaks. Winter is a suitable time for crack injection maintenance.
• Residential and Commercial Basements: Treat leaks in cracks and joints.
• Slab Undersealing: Similar to curtain wall grouting, but it's done through the floor.

When the residue of plants or animals is converted into soil, the process is known as decomposition. Bacteria, fungi, and worms break down this residue, taking nutrients from them and leaving the remaining portion. Organic molecules are broken down into simpler inorganic molecules. This biological process changes the makeup of the soil and can therefore lead to soil instability.

What are the causes of decomposition?

When soil has a high concentration of organic materials, the soil will naturally begin to decompose. Throughout this process of decomposition, the mass and form of these organic materials will change. Up to 90 percent of organic material will actually disappear over the course of the decomposition process, which means the mass of the soil will decrease substantially, reducing the quantity of available soil. The causes of decomposition can be broken into two main groups: manmade and natural. Trash pits or buried construction debris can cause manmade decomposition, while tree stumps and peat content can cause natural decomposition. 

What are the signs of decomposition?

Sinkholes, unstable soil, and low spots are all indications of soil decomposition. When soil begins to decompose and shift, it can compromise the integrity of buildings, foundations, and other manmade structures. 

How can decomposition be addressed?

In some cases, it is possible to dig up the cause of decomposition. For example, it might be possible to extricate a trash pit or old construction debris from the soil. However, in other cases, this simply isn’t feasible. You can’t easily extricate a trash pit after you have already built on top of it. If removal isn’t an option, the best solution is to envelop the area with polyurethane soil stabilization material. This process is known as encapsulation, and it essentially works to compact the area and reduce the amount of oxygen and water that can get to it, thereby helping to slow decomposition.

What is freezing and thawing?

As the name suggests, a freezing and thawing cycle refers to a natural phenomenon in which soil freezes in cold weather and then thaws out again once the temperature warms up. Freezing and thawing in northern climates is good news for farmers, as it helps to loosen up the soil and reduce compaction, which makes it easier for crop roots to grow. However, for construction engineers and contractors, this process can prove to be incredibly problematic, especially if they are building on fine-grained soils with silt or clay factions, which are more prone to freezing and thawing.

What are the problems associated with freezing and thawing?

Essentially, freezing and thawing cycles accelerate soil instability. Soil with pores containing small particles of frozen water is known as permafrost. Building on permafrost is fine, as long as the soil stays frozen, but things become problematic once the permafrost begins to thaw. Freezing and thawing of permafrost cause soil to become soft and less compact. Subsequently, this causes structures, such as roadways, railways, foundations, and pipeline supports, to sink. Obviously, this can cause major headaches.

How can the problem of freezing and thawing be mitigated?

Alchatek soil stabilization products can be used to compact the ground and displace water particles in the soil pores. Depending on the soil type, this could prevent frost heave, resulting in a stronger, more consistent base to build on.

Want in-depth info on soil stabilization procedures and products?

Many types of infrastructure, including roads, bridges, and buildings, depend on compacted soil in order to stay in place. Therefore, in order for these structures to last, a specific degree of compaction must be achieved. When soil does not adequately compact, the problem is known as poor compaction, and that can lead to more serious issues. Concrete repair contractors always need to be on the lookout for signs of poor compaction which include settling slabs, cracking foundations, and dips in roadways and railroads.

What causes poor soil compaction?

There are a variety of causes of poor soil compaction. However, much of it boils down to soil texture and soil properties. Some soils are more prone to compaction than others. Excess soil salt content, high clay fraction soils, low pH soils, and soils with high water content tend to compact less favorably. It should also be noted that decisions made by construction contractors and their teams can also influence soil compaction. For example, failure to select proper compaction equipment or compaction materials can contribute to poor compaction. Furthermore, some areas are more prone to poor compaction than others, such as portions of soil set against a foundation.

How can poor soil compaction be corrected?

Luckily, poor compaction can be corrected. The solution is to strengthen the soil until it is properly compacted. As mentioned in the previous post, voids can be filled, soil consolidated, and water migration halted with Alchatek soil stabilization products. Once the bearing capacity of the soil has been increased with this process, then the structure can be lifted if necessary.

What is erosion?

In geological terms, erosion can be defined as an exogenic process that moves a portion of the earth’s crust from one location to another. This includes a range of different processes, including water flow, wind, and even human action, that move dirt, soil, rock, etc. They are called exogenic processes because they originate outside of the earth’s crust, or externally. In more practical terms, erosion can best be described as the way in which the earth is worn away by water, wind, or ice. So when a river carves a canyon out of stone (such as when the Colorado River carved out the Grand Canyon in Arizona over the course of so many years), that is an example of erosion. The formation of sand dunes by the wind moving across the desert is also an example of erosion, as are changes in rocks along a shoreline due to the constant thrashing of waves. 

Why does erosion cause unstable soil?

You’ve probably heard that erosion is dangerous because it causes unstable soil. It is important to remember that the consequences of erosion can potentially be dramatic, causing landslides and structural damage. After investing money in the construction of a building, the last thing you want is for unstable soil to put the whole project at risk. 

How can erosion be repaired?

Voids can be filled, soil consolidated, and water migration halted with Alchatek soil stabilization products. Once the bearing capacity of the soil has been increased with this process, then the structure can be lifted if necessary.

Want in-depth info on soil stabilization procedures and products?

Unstable soil can be defined as soil that will not stay in place on its own and therefore requires extra support. It should be noted that unstable soil can threaten the stability, security, and safety of infrastructure and can damage, degrade, and even destroy a number of structures, such as buildings, bridges, and roads.

Let's look at the four main causes of unstable soil...

Erosion

Erosion refers to processes in which external elements (wind, water, etc.) remove soil or rock from a certain location and transport it to another location. There are a variety of different erosion types, including river and gull erosion, wind erosion, and erosion attributed to human activity. Erosion ultimately destabilizes soil and can lead to landslides and sinkholes.

Poor Compaction

One of the most common causes of unstable soil is poor compaction. In some cases, certain types of soil are simply very loose and subsequently not compact. The cause of this is typically an imbalance of mineral pieces, organic matter, air, and water. For example, clay soil with very high moisture content will inevitably become unstable, as it will be incredibly difficult to compact. Similarly, soils with high sand content will be difficult to compact.

Freeze/Thaw

Processes of freezing and thawing essentially accelerate erosion processes. Cold weather freezes moisture trapped in tiny cracks. When this water freezes, it expands, subsequently pushing on the rocks and breaking them into smaller pieces. As processes of freezing and thawing continue, rock and sediment are continually broken down.

Decomposition

When soils contain a high concentration of organic materials, such as topsoil and plant matter, they will decompose, subsequently causing them to become unstable. This is because organic materials rapidly change form and mass as they decompose in the soil. In fact, up to 90 percent of organic material will disappear over the course of the decomposition process.

Fortunately, stability can be restored to soil with ultra-low viscosity polyurethane resins. Foaming and permeation polyurethanes can mitigate the damage done by processes of erosion, decomposition, freezing, and thawing, as well as help to rectify compaction problems. When it comes to unstable soil, you can’t afford to take a risk. Stable soil is crucial to maintaining secure structures.

Raising Concrete with Confidence

When pumping a lightweight material beneath a slab, you need the confidence that it is strong enough for the application. How strong is strong enough? This is a commonly asked question by contractors that are new to slab jacking with polyurethane. Alchemy-Spetec structural foams only need to be as strong as dirt, but they're actually stronger than crystalline bedrock.

The Right Strengths for Concrete Lifting

Slab lifting foams are rated on density (weight per cubic feet) and compressive strength. This testing and rating are based on the foam in a free-rise state; the parts A and B are mixed together and allowed to expand freely. Our AP Lift 430 and AP Lift 475 structural lifting foams, for example, weigh 2.75 – 3.25 lbs (AP Lift 430) to 4.75 – 5 lbs (AP Lift 475) per cubic foot. But they have compressive strengths of 50 psi and 100 psi in a free-rise state. That's the equivalent of 7,200 to 14,000 lbs per square ft of support, just in a free-rise state.

Polyurethane Slab Jacking Compared to Clay and Bedrock

To put that into perspective, the National Home Builders Association and the International Building Code list stiff clay at 4,000 psf and crystalline bedrock as having 12,000 psf of load-bearing capacity. Consider the job site conditions where the foam will be injected into a confined area. Testing data in the lab shows that our lifting foams will increase in compressive strength: In a space confined 25% by volume there will be an increase of 31% in psi and in a space confined by 75% there will be a 79% increase in the psi.

Concrete Leveling for Any Job with the Right Foam

Today polyurethane concrete lifting foams are used to level airport slabs supporting jumbo jets, equipment and building slabs supporting tremendous loads, and even railway sleepers that support the heaviest freight trains. So don't let the word “foam” fool you. These resins cure to strengths beyond what is needed to support any structure.

Whether your focus is on soil stabilization, leak seal, or slab lifting, it’s a known fact that growing your contracting business is hard work. As an experienced consultant and advisor, I am aware that many contractors focus so much time on generating new leads that they may overlook another great source of new revenue: re-engaging past customers.

It costs about five times more money to attract a new customer than to sell to an existing customer. And it's 50% easier to sell to an existing customer than to a new customer. It has also been said that 80% of most business revenue comes from just 20% of its existing customers. (Source: Forbes Magazine's "Five Customer Retention Tips for Entrepreneurs".)

Owners and managers of these types of properties are likely to provide repeat business...

• Commercial properties
• Multi-unit residential properties
• Schools, universities, education departments/districts
• Municipalities/government agencies

If you put your mind to it, I'm sure you can think of a few more. You can also reach out to previous individual residential and small business customers occasionally.

Customer Retention Tips

Remember, customers do not owe you their loyalty, it has to be earned. You may be the most qualified and diversified contractor in the area, but if you want to get that repeat business you have to implement a retention program. Here are a few suggestions...

• Create an email newsletter. Send out tips and advice that your customer base may find helpful. You can also include case studies or success stories from recent jobs. Holiday greetings are always good as well. Throw in a promotion or discounted service offer every now and then, but make sure your communications are always primarily focused on useful content.
• Gifts, holiday cards, and birthday cards are a nice way to express customer appreciation. Sending items like this via traditional mail will help you stand out from the crowd a bit, as more and more people are moving towards a "digital only" approach.
• Take a moment on a regular basis to check up on your past customers' social media accounts. Like, favorite, and share anything you find relevant or interesting. This is just another way to remind them that you're interested in how they're doing and that you're available should they need any further assistance.

Take some time to brainstorm and I bet you'll come up with some unique approaches of your own. If you're too busy to do this kind of stuff, hire a part-time assistant. The jobs you get as a result of these activities may pay for the assistant, and then some. Give it a shot and find out.

Many of the contractors I’ve worked with over the years have had to give a presentation at one time or another. In some cases, they need to make a pitch to a potential client (for example at municipality or state agency contract meetings). In other cases, they have the opportunity to market their services by giving presentations at trade shows, “lunch and learn” seminars, webinars, homeowner association meetings, professional association events, etc.

Presentation opportunities can sometimes arise on short notice. This is why you can benefit from creating presentations ahead of time. If you’d like, you can ask our marketing team to critique your presentation. You can also inquire about getting a member of our sales team to co-present when an opportunity does come along.

Incorporate the following tips to create a powerful presentation for your contracting business. Some of these suggestions may seem contrary to everyday conventional practice, but who wants a run-of-the-mill presentation? We’ve tested this approach time and time again, with consistently positive results. It will be worth your while to at least give it a shot.

Fewer Words

As a detail-oriented professional, you may be inclined to pack your presentation slides with lots of text in order to get all your important points across. This is not the most effective way to give a presentation. It can lead to information overload and a drowsy, impatient audience. When creating a presentation, you want to condense the information and only include text that is absolutely essential.

Powerful Images

Now that you have seriously scaled back your text use, the next step is to make the presentation livelier. The audience needs to be actively engaged rather than bombarded with data. If you associate a powerful image with each essential point, the audience is better able to visualize and remember the concept.

Engaging Stories

Once you have simplified your text and added visually striking images, you can add extra punch by incorporating stories to get your points across. As a contractor, you probably have many stories from the trenches. Telling a story is a surefire way to make sure a message sticks.

White Paper Instead of Note-Taking

One thing that dilutes the impact of even the most powerful presentations is audience note-taking. This habit guarantees that half their time is spent looking down at their desk rather than paying attention to you. That’s why it’s helpful to prepare a whitepaper (basically a multi-page essay with any essential graphics) that summarizes all the key points from your presentation. Inform the audience up front that there is no need to take notes, as they will receive a written summary afterward. Explain to them that they’ll get a lot more out of the presentation if they provide their full attention.

Conclusion

Since I believe in giving credit where credit is due, I'd like to acknowledge that most of these ideas came from the book Presentation Zen: Simple Ideas on Presentation Design and Delivery by Garr Reynolds.
