Sand permeation involves injecting or permeating sand or a similar granular material into loose or weak soils. The primary purpose is to fill gaps and voids between soil particles, thereby increasing the density and stability of the soil.
Site Assessment: A thorough analysis of the soil properties and conditions is conducted to determine the suitability of sand permeation for a given site.
Selection of Material: Sand or a similar granular material is chosen based on the soil type and the desired outcome. The material's grain size and shape are crucial factors that affect the permeation process.
Injection Method: There are different resins that can be injected into the soil using various techniques. One common method is using pressurized air or water to carry the sand deep into the soil layers.
Filling Voids: As the resin permeates the soil, it fills the voids between soil particles. This reduces the pore space and increases the contact points between grains, leading to greater friction and interlocking.
Increased Density and Stability: The polyurethane resin increases the density of the soil, thereby enhancing its load-bearing capacity and resistance to deformation or settlement.
Foundation Support: Used to strengthen the soil beneath foundations, particularly for structures such as buildings, bridges, and roads.
Erosion Control: Helps in controlling erosion in areas where soil particles are prone to being washed away.
Ground Improvement: Enhances the overall stability of the ground for construction projects, especially in areas with loose or sandy soils.
Non-Invasive: Less invasive compared to some other soil stabilisation methods.
Environmentally Friendly: Can be a more environmentally friendly option.
Versatility: Suitable for a variety of soil types and construction scenarios.
Sand permeation focuses specifically on stabilising loose, granular soils by injecting sand, offering advantages like minimal environmental impact and rapid implementation.
While highly effective, sand permeation is most suitable for sandy and loose soils. A preliminary site assessment helps determine its appropriateness for your project.
