Filling the voids under the footings" Measures against subsidence include the "TerraTech method.
The continuously sinking stepping board can be stabilized against subsidence with cavity filling.
■TerraTech Method for Suppressing Settlement of Footing Slabs The TerraTech method involves injecting a special polyurethane resin called "TerraTech" into voids that occur beneath footing slabs due to ground subsidence. By utilizing the expansion force of the resin, the voids are filled, the ground is compacted, and the footing slab is lifted. This patented method (Patent No. 4896949) addresses the concentrated loads at the edges of the footing slab caused by the formation of voids, which can accelerate the settlement of the slab and lead to issues such as wobbling. By filling the entire area beneath the footing slab with the TerraTech method, concentrated loads are alleviated, and the load is effectively transmitted to the ground. 【Features】 ◆ Installation of a single footing slab in one day ◆ The injected material is lightweight (about 1/30th the weight of mortar), significantly reducing the risk of ground subsidence due to its own weight ◆ The curing time of the injected material is quick (about 30 seconds), resulting in shorter road closure times and minimal penetration into the ground ◆ Does not use VOCs (volatile organic compounds), making it environmentally friendly and highly safe ◆ Reduces maintenance and repair costs that would otherwise need to be repeated multiple times ● For more details, please download the catalog or feel free to contact us.

basic information
The urethane resin injection method was introduced to Japan in 2001, evolved uniquely within the country, and obtained a patent in January 2016. ● TerraTech Method Flow for Filling Cavities Under Roads 1. Drill a hole with a diameter of 6 mm, smaller than a one-yen coin, at the target location. 2. Use specialized equipment to inject resin under the road. 3. The injected resin begins to expand instantly. This expansion compresses and strengthens the ground, pushing up the sunken slab. 4. Confirmation of the filling is conducted through confirmation holes, etc. * Injection work: All equipment is mounted on one truck. ● Road Surface Restoration 1. Restore the injection and confirmation holes with cold mix materials, etc. ● Features of the TerraTech Method for Filling Cavities Under Roads 1. No excavation work is required, and since the injection hole is φ16mm, there are no remnants of construction and no step formation occurs. 2. The standard working time per location is about 50 minutes, minimizing traffic regulation time. 3. 80% of the final strength of the resin is achieved in 10 minutes, allowing for immediate safety assurance.
