Soil Stabilization

Common Causes for Soil and Subsoil Failures and Destabilization

Both natural and man-made causes can lead to weak soils beneath structures. The original soil material/composition may not have been packed properly before construction, or nearby drilling or excavation may result in compromised soil quality. Regardless of the cause, weak soils and subsoils result in subsidence, generally caused by the extraction of groundwater, which leads to the formation of voids in the base and subbase soil beneath the structure. Symptoms of weak soils under government, commercial, industrial, or residential properties include:

  • Foundation Settlement
  • Cracks in Slabs and Foundations
  • Heaves and Dips in Slabs, Roadways and Parking Lots
  • Leaks and Cracks in Underground Utility Pipes and Structures
  • And More

There can also be evidence of soil subsidence in adjoining and nearby properties.

Soil subsidence is a common problem in Florida. The stability of any structure or concrete slab is based mostly on the soil properties it is built upon. Florida’s sandy, limestone soils and geological conditions can cause voids in soil underneath foundations, concrete slabs, roadways, and structures. Under overbearing weight, the supporting soils will become inadequate to support the structures built upon them. When settlement occurs, it can destroy the value of the property/structure and even render it unsafe.

Soil Stabilization Methods

Structural Chemical Grouting

In granular soils, chemical grouting fills the voids and pockets in soils and subsoils then bonds them together, stabilizing and lifting the soils and structure while creating a significant increased weight bearing capacity. This method it widely used for government, infrastructures, industrial, commercial, and residential buildings, and properties. Structural chemical grouting is also used to repair fractures in concrete and rock. When the grout is injected into the cracks and fractures it fills the voids with a powerful grabbing adhesive. It repairs the integrity of the concrete structure and rock and creates a waterproof bond.

Water Control Chemical Grouting

Is most often used to stop water flow in soils and subsoils. Injection points are laid out in a well-defined grid/curtain, then under pressure, chemical grout is injected into the grid pattern which allows it to interconnect. This fills the voids in the soil and creates an underground curtain/wall that prevents water/fluid migration. Water control grouting is widely used as a cost-effective way to stop leaks in underground utilities, storm drain & sewer systems, tunnels, underground tanks/structures, elevator shafts, manhole catch basins and nearly any underground structure. Underground grout curtain/walls are created at water flow points to stop the leaks and water/fluid flow into the structure. The job can be completed inside or outside the structure depending on accessibility.
