Chemical Grouting

Chemical grouting is a specialized technique employed in construction and geotechnical engineering to address soil stabilization, foundation repair, and waterproofing challenges. Unlike traditional grouting methods, chemical grouting involves the injection of fluid grouts into the soil or structures, where they undergo a chemical reaction to solidify or alter the properties of the surrounding material. This process is particularly effective in sealing leaks, filling voids, and improving the load-bearing capacity of soils. 

Chemical grouting offers versatility in addressing a wide range of issues, including the stabilization of loose or erodible soils, the mitigation of water infiltration in underground structures, and the repair of foundation cracks. The precision and adaptability of chemical grouting make it a valuable solution for enhancing the durability and structural integrity of various construction projects.

How are we different?

Adcos International strives to provide a safe, easy to apply, and durable chemical solution to all stakeholders. Doing it right the first time is critical to the longevity of the structure.

Our products are based on the closed cell foam technology to provide permanent effectiveness against high water ingress. This is different from most products in the market, which uses water-reactive foams (open cell) as temporary water-stopping measures.

In open cell technology, the open cell matrix works like a sponge, and hence even in compacted form, the foam remains permeable. This will saturate causing water leakage issues to reappear. In order to achieve a durable elastic seal, a backup or 2nd pass injection is required.

In closed cell foam technology, since the cell structure are smaller and denser with little to no spontaneous capillary absorption, there is no need for a 2nd pass injection. We recommend the closed cell foam technology over the open cell technology as it provides a more permanent solution with just a single injection. Multiple drilling into concrete can cause severe long term consequences such as structural deterioration, and problematic water ingress.

Common Uses of Chemical Grouting

Soil Stabilization

Chemical grouting is frequently employed for soil stabilization in construction and geotechnical engineering. By injecting grout into loose or erodible soils, the chemical reaction within the grout strengthens the soil, improving its load-bearing capacity and preventing settling.

Foundation Repair

The injection of grout into voids or beneath foundations helps to stabilize and lift structures that may have settled or experienced differential movement, providing a cost-effective alternative to more invasive foundation repair methods.

Waterproofing and Sealing

Chemical grouting is an effective solution for waterproofing and sealing structures. By injecting grout into cracks, joints, or voids, it creates a water-resistant barrier, preventing water infiltration. This is particularly valuable in applications such as tunnels, basements, and underground structures.

Infrastructure Rehabilitation

Chemical grouting can be used to repair and strengthen concrete structures, including bridges and dams, by filling voids, stabilizing foundations, and mitigating issues related to soil erosion. This application helps extend the lifespan of existing infrastructure without the need for extensive demolition and reconstruction.

The Process of Chemical Grouting

Chemical grouting typically involves injecting a fluid grout mixture into the targeted area, such as soil, voids, or cracks in structures. The injected grout undergoes a chemical reaction, resulting in the formation of a solid, impermeable mass. This reaction serves to stabilize soils, lift and support foundations, or create a water-resistant barrier. The success of the process relies on careful planning, accurate injection, and the selection of an appropriate grouting material tailored to the specific needs of the project. Chemical grouting offers a minimally invasive alternative to traditional construction methods, allowing for efficient and cost-effective solutions while minimizing disruption to existing structures or surrounding environments.

Benefits of Chemical Grouting

Non-Invasive Solution

Chemical grouting provides a non-invasive alternative to traditional construction methods. The process typically requires small injection points, minimizing disruption to existing structures and surrounding environments. 

Versatility in Applications

Chemical grouting is a versatile solution that can be applied to a variety of construction and geotechnical challenges. Whether it's stabilizing soils, repairing foundations, or waterproofing structures, the adaptability of chemical grouting makes it suitable for addressing a wide range of issues. 

Cost-Effective Repairs

Chemical grouting often proves to be a cost-effective solution for repairing foundations and stabilizing structures. Its non-invasive nature reduces labor and material costs associated with traditional construction methods.

Minimized Downtime

The application of chemical grouting typically involves quick curing times, allowing for minimal downtime during construction or repair projects. This rapid curing facilitates swift stabilization of soils, expedited foundation repairs, and timely completion of tasks, contributing to overall project efficiency.
