The challenge for managers of water control structures is determining what kind of maintenance needs to be done to prepare for the rainy season. Over our 20-year history, we have evolved the use of chemical grout in flood control structure rehabilitation and seepage barrier repair, reducing manager’s costs and construction timelines. So, what are some applications that chemical grout can be utilized to help you prepare for this rainy season?
What is Chemical Grout?
Chemical grout is a two part highly expansive polymer that is used to void fill and stabilize soils. Due to its highly expansive nature, hydro insensitivity, and strength, chemical grout is highly effective for stabilizing water control structures and protecting them against water seepage and erosion.
Void Filling and Soil Stabilization
Once injected chemical grout expands up to 20 times its initial volume. When the grout enters the treatment zone it is initially in liquid form. Like water, it saturates the area finding the path of least resistance. Once expansion begins, the material begins to permeate the soil, filling any annular voids throughout the soil and below the structure. Depending on the project goals, this process can be used to fill voids, soil stabilization, and restore or increasing the bearing capacity of base foundation soils. If there is any present water, the polymer will displace it and push it away. Due to the chemical grout’s hydro-insensitivity and its binding of soils, the process will mitigate future washout and erosion.
Injectable Seepage Barrier
Another innovative method for utilizing chemical grout has been that of an injectable seepage barrier wall. An injectable seepage barrier is created by injecting a dense, non-permeable layer of chemical grout where water migration is an issue. The injectable seepage barrier is also an excellent complement to sheet pile walls for sealing it against leakage. Additionally, our polymers are NSF-61 Certified and are environmentally inert, so there are no concerns regarding long-term environmental impact
Applications Where Chemical Grout is of Use
There are many applications where Chemical Grout is of great use. Here are some examples:
- Void-filling underneath Spillways, Approach Slabs, Manholes and Buildings
- Soil Stabilization and Densification
- Lateral Line Sealing
- Injectable Seepage Barriers
- Slab lifting and Realignment
- Seepage Barrier Repair
Why Chemical Grout?
Chemical Grout is fast, efficient, light-weight and cost-effective.
- Fast – Chemical Grout sets up to 95% within 15 minutes after injection. The results are immediate and the facilities operations are virtually unaffected.
- Efficient – Moisture content isn’t an issue for chemical grout. Because of this, no matter the soil conditions, chemical grout can be used. Additionally, EagleLIFT has over 20 years of experience in directing its injection patterns to ensure the project goals are a success.
- Light-Weight – Due to the exothermic reaction and close-celled nature of EagleLIFT’s polymers, the polymer is light-weight and strong. The polymer is 200-400% lighter than cementitious and permeation grouts
- Cost-effective – because it takes less of our material, less time and low project footprint, using our polymers is significantly more cost-effective than the competition.
- Safe – Our products are NSF-61 certified, to make sure we have no impact on environmentally-sensitive areas or drinking water supplies.
