Deep Lock® is a specialized deep soil stabilization process developed by Alchatek. It involves injecting a structural polymer deep into the soil, where it expands and solidifies. This process enhances the stability and strength of the soil, making it an effective solution for various geotechnical challenges. One key feature of Deep Lock® is its ability to stabilize soil below the freeze/thaw line, making it particularly useful in cold weather conditions.
Applications of Deep Lock® in Cold Weather
- Foundations: Deep Lock® is extensively used to stabilize and strengthen foundations, especially in areas where the soil is compromised due to moisture or other factors.
- Under Sunken Slabs: For sunken slabs, where soil erosion or voids have occurred deeper down, Deep Lock® provides an effective solution to fill and stabilize these gaps.
- Settling Structures: Entire structures that are settling, not just the slab, can benefit from the deep soil stabilization offered by Deep Lock®.
- Interior Footings: In scenarios where exterior piers are used for stabilization, Deep Lock® can be employed for interior footings, avoiding damage to floors and providing a balanced stabilization approach.
- Brick and Stone Foundations: These types of foundations, which are challenging to stabilize with piers, can be effectively supported using the Deep Lock® process.
- Pre-construction Soil Stabilization: Before construction begins, stabilizing the soil ensures that the foundation rests on solid ground, a crucial step for long-term structural integrity.
- Culverts: Deep Lock® can be used for stabilizing and sealing culverts both from the outside (probe-grouting style) and from the inside by injecting the polymer just below the steel.
Why Deep Lock® is Used in Cold Weather
Cold Weather Performance: Deep Lock® can be performed even when the top layer of soil is frozen, making it ideal for cold weather applications.
- Addressing the Root Cause: By stabilizing soil deep below the surface, Deep Lock® addresses the underlying causes of structural problems rather than just the symptoms.
- Preventing Resettlement: It ensures that once slabs or structures are stabilized, they remain in place without resettling.
- Warranty Benefits: When employing the Deep Lock® process, contractors can offer better warranties due to effective and long-lasting stabilization.
- Ease of Process: The process is relatively easy to learn and implement, making it a practical option for a wide variety of contractors.
Deep Lock® offers a versatile and effective solution for a range of soil stabilization needs, particularly beneficial in cold weather conditions. Its ability to work below the freeze/thaw line and address deep-rooted soil issues makes it an invaluable tool in the geotechnical contractor’s arsenal.



For contractors seeking productive work during the slower winter months, Alchatek is here to help every step of the way.


It's time to revisit the idea of remaining profitable during the winter months, but where does one begin?
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.
Alchatek specializes in cutting-edge solutions for infrastructure repair, including the use of polyurethane grouts for sealing leaks. In addition to manufacturing repair materials, we can refer you to contractors skilled in a wide range of applications, from crack injection to curtain wall grouting and more. We're passionate about helping municipalities and other organizations make the most of their budgets while ensuring the long-term integrity of their infrastructure.


Proactive budget planning is essential, especially as the fiscal year nears its end, for sustainable city growth. Advanced leak sealing demonstrates an impactful way to utilize end-of-year budgets. Strategic spending can yield long-term municipal benefits through enhanced infrastructure integrity. Forward-thinking budget optimization, aided by innovative repair and maintenance solutions, is key for sustainable, resilient growth.
In the realm of infrastructure repair, innovation often defines the line between outdated methods and cutting-edge solutions. One such innovation that stands out is the use of polyurethane grouts for sealing leaks. The advantages of polyurethane leak seal are especially apparent in the context of crack injection and curtain wall grouting.
In the realm of municipal budgeting, the approach of year-end spending often prompts considerations about where to direct the remaining funds. While the temptation might be to disperse these resources broadly across different areas, it's vital to stress the importance of prioritizing infrastructure projects, specifically those related to sealing leaks.
In the world of municipal finance, the phrase "use it or lose it" carries significant weight. This concept revolves around the annual budgeting process, where funds allocated to a municipality must be spent within a specific fiscal year, or they risk being forfeited.
