Winter weather creates unique challenges for polyurethane slab lifting operations. As temperatures drop, proper equipment care becomes essential for successful projects. Here are vital tips to keep your rig running smoothly during cold weather and properly stored at season's end.

Cold Weather Operation Essentials 

Operating in cold conditions requires specialized heating equipment. The proper function of the pump's A/B preheaters and the hose heater is the biggest factor for pumping in cold weather. Without these heaters, the material cannot warm up or stay warm. Additionally, heated hoses with copper coils or internal wiring keep material flowing smoothly through the system.

Temperature Management Strategies 

Maintaining the correct material temperature is crucial for optimal performance. Therefore, barrel temperatures should stay between 70° and 80° Fahrenheit. During winter months, achieving these temperatures takes longer due to overnight cold. Consequently, keeping barrel heaters running overnight can help maintain proper temperatures. Most importantly, regular material recirculation ensures consistent heating throughout the system.

Winter Storage and Maintenance 

Proper end-of-season maintenance protects your investment. Flush the pump system thoroughly with Alchatek Pump Flush until all iso discoloration disappears. Run the end of the hose through cheesecloth to catch crystallized iso particles. Finally, fill the system with Alchatek Pump Saver 195 for long-term storage. For detailed step-by-step instructions, contact the Alchatek support team at 404-618-0438.

Safety First: Winter Precautions 

Safe winter operations require proper protective equipment. Start with appropriate goggles and a respirator. Furthermore, always work in well-ventilated areas to ensure adequate air circulation.

Deep Lock® is an innovative process developed by Alchatek that utilizes high-quality structural polymers to address deep soil issues. This powerful, painless, and rapid solution stabilizes soil at all levels, ensuring long-lasting results with minimal disruption to the property. This article profiles the two main types of Deep Lock® soil stabilization work and the specific situations in which each type is most effective.

Jobs Requiring One Component Grouts (AP Fill 700 and AP Fill 720)

One-component grouts, such as AP Fill 700 and AP Fill 720, are used for permeation grouting. Permeation grouting involves injecting a low-viscosity grout to saturate loose soil and, upon curing, create a solid, stable mass. This type of Deep Lock® work is ideal for the following situations:

• Loose Soil: When dealing with loose, unstable soil, permeation grouting can effectively bind the soil particles together, creating a stronger foundation.
  
  
• Curtain Walls: One component grouts are often used to create subsurface barriers, or curtain walls, to prevent water infiltration or contain contaminants.
  
  
• Zero-Point Excavation: In cases where excavation is not feasible or desirable, permeation grouting can be used to stabilize the soil without disturbing the surface.

Jobs Requiring Two Component Structural Polymers (AP Lift 430, AP Lift 440, and AP Lift 475)

Two-component structural polymers, like AP Lift 430, AP Lift 440, and AP Lift 475, are used for compaction grouting. Compaction grouting involves injecting a highly viscous grout under pressure to compact and displace the surrounding soil. This type of Deep Lock® work is best suited for the following situations:

• Hard Clay Soils: Two-component structural polymers are effective in densifying and strengthening hard clay soils, which can be challenging to treat with other methods.
• Non-Sand/Silt Mix: When the soil composition is not primarily sand or silt, compaction grouting with two component polymers is often the most effective solution.
• Lifting Involved: If lifting of the structure or surface is desired, two component structural polymers are the ideal choice. These polymers expand after injection, providing controlled lifting force.

Two-component structural polymers offer more versatility than one-component grouts, as they can address a wider range of soil types and provide the added benefit of controlled lifting.

A Versatile Process for Soil Stabilization Work

The Deep Lock® process, with its range of high-quality structural polymers, provides a powerful and efficient solution for addressing deep soil issues. By understanding the specific characteristics of one-component grouts and two-component structural polymers, contractors can select the most appropriate approach for each unique situation. Whether dealing with loose soil, hard clay, or the need for controlled lifting, Deep Lock® has the tools and expertise to deliver rapid, long-lasting results with minimal disruption to the property. Alchatek's soil stabilization polymers are NSF-certified for contact with potable water. This means they meet the EPA's strict environmental standards as defined in the Safe Drinking Water Act (SDWA).

While Alchatek's Deep Lock® process is primarily used on deep soil stabilization jobs, there are specific situations in which deep soil stabilization may be needed to reinforce soil on slab lifting jobs. In cases where slabs are bearing heavy loads, have significantly loose soil underneath, or are located in areas where access is limited, incorporating the Deep Lock® process can help address the underlying soil stability issues. With the addition of the Deep Lock® soil stabilization process, contractors can achieve effective, minimally invasive slab lifting results while simultaneously improving the long-term stability of the foundation.

Slab Lifting for Heavy-Duty Environments

The Deep Lock® process is particularly well-suited for slabs that regularly bear heavy loads, such as:

• Factory floors
• Forklift ramps
• Loading areas
• Fire stations
• Airport runways
• Launchpads

In these high-traffic, heavy-duty environments, soil erosion, poor compaction, and biological decay can lead to slab settling and instability over time. Traditional methods of soil stabilization often fail to address deeper soil issues and can require extensive excavation, heavy equipment, and prolonged downtime.

Deep Lock®, on the other hand, gets to the root of the problem by stabilizing the soil at all levels beneath the slab. The process involves thorough site evaluation, saw cutting of joints if necessary, and the strategic injection of AP Lift structural polymers through small holes drilled in the slab. The expansive properties of the foam fill voids, compact loose soil, and lift the slab back to its original level position.

Soil Stabilization and Slab Lifting for Loose Soil Conditions

This process is also ideal for slabs with significantly loose soil underneath, where erosion or poor compaction has created unstable conditions. By permeating and densifying the soil with AP Lift polymers, contractors using this Deep Lock® process create a strong, stable substrate that can support the slab for decades to come.

Minimally Invasive Slab Lifting for Sensitive or Inaccessible Areas

Another key advantage of applying the Deep Lock® process is the ability to address slab issues in sensitive or inaccessible areas, such as in historical buildings where drilling from the inside is not possible. Because the process involves minimal drilling and can be performed entirely from the exterior, it offers a non-invasive solution for preserving and rehabilitating delicate structures.

Deep Soil Stabilization on Slab Lifting Jobs

Alchatek's Deep Lock® process provides a comprehensive solution for slab lifting and soil stabilization, with powerful results, painless procedures, and rapid return to service. For any slab that regularly bears heavy loads, has significantly loose soil underneath, or requires a minimally invasive approach, Deep Lock® offers a cutting-edge alternative to traditional repair methods. In addition, most Alchatek polymers are NSF-certified for contact with potable water. This approval verifies that the product complies with the strict environmental regulations established by the Safe Drinking Water Act (SDWA).

Have you ever noticed shallow, pond-like formations on the surface of roads, particularly in private neighborhoods, subdivisions, or parking lots? These are known as "bird baths" in the road surface, and they're more than just a quirk of the road. They signify deeper issues in road maintenance and safety that are crucial to address.

What are Bird Baths in Road Pavement?

Bird baths are small depressions in the road surface where water accumulates. Unlike potholes, bird baths are shallower and often wider, resembling a natural birdbath. They typically form in areas where the pavement has sunk or where water is unable to drain properly. These features are commonly seen in areas with lower traffic, like private neighborhoods and parking lots, where regular maintenance may not be as common.

Causes and Consequences

The primary causes of bird baths in pavement include tire ruts from repetitive vehicle traffic and insufficient soil compaction during road construction. Over time, the weight of vehicles passing over the same spot causes the pavement to deform, creating these depressions. Additionally, if the underlying soil was not compacted properly, it can settle unevenly, leading to surface irregularities.

The presence of bird baths is not merely a cosmetic issue. They can pose significant trip hazards for pedestrians, especially when hidden by water or ice. For vehicles, these depressions can lead to uncomfortable rides and, in some cases, damage to the vehicle itself. In winter, bird baths can be particularly dangerous as they form ice patches, posing a risk for both vehicles and pedestrians. Furthermore, they can also cause problems for snowplows, leading to inefficient snow removal and additional road wear.

Road Pavement Birth Baths

Understanding the causes and effects of bird baths in road pavement is crucial for effective road maintenance and safety. Addressing these issues not only improves the longevity of the pavement but also ensures a safer environment for all road users. The next part of the series will delve into bird bath repair methods, focusing on innovative techniques offering long-lasting solutions, such as the Deep Lock ® process.
