Over time, the soils beneath concrete slabs and paved surfaces can shift, erode, or lose compaction due to water movement, drainage issues, and natural ground settlement. When this occurs, the concrete above may begin to lose support leading to cracking, sinking, or uneven surfaces that can create safety concerns across commercial properties.
Our polyurethane grouting service provides property maintenance teams with an effective method for stabilizing soils and restoring support beneath concrete without the need for excavation or major construction.
The process involves injecting a specialized expanding polyurethane material into the ground with low pressure through small access points. As the material expands it fills underground voids, compacts loose soils, and creates a stable support layer beneath the concrete structure. Polyurethane grouts can also be single or multi-component and can require a reactant or react when encountering water in areas where high volumes of moisture are present.
This technique allows underlying soil issues to be corrected while minimizing disruption to tenants, traffic, and daily property operations.
