Some useful construction tips for ground improvement or ground treatment

Ground Improvement or Ground treatment means “controlled modification of the condition, type or mass behavior of ground materials to attain a projected suitable response to existent or proposed environmental and engineering actions.”

The soils and fills become solid with vibration. Vibrating rollers are utilized for condensing comparatively thin layers of earth fill and bituminous road materials. It is applied with vibration to consolidate the ground in place and to depth either by clearing the ground through a vibrator or evoking extreme level of energy at the ground surface or at certain points inside the ground. Given below some most recognized processes for perfect ground treatment;

  • Vibro-compaction
  • Vibro stone columns
  • Dynamic compaction
  • Rapid impact compaction
  • Vibratory probing
  • Compaction piles
  • Blasting

Ground Improvement with inclusion of Load or enhancing operative stress
When load is delivered on the ground, it is compressed. The range and required time may vary according to the placing of ground particles, on the degree of saturation as well as smooth draining of the soil. If load is delivered for loose and specifically unsaturated fills, it can cause quick settlement.

It takes prolonged time for soft and saturated clays to solidify under an added load when pore pressures disperse and the operative stress in the soil enhances. Given below some significant ground treatment processes;

  • Pre-compression
  • Vertical drains
  • Inundation
  • Vacuum pre-loading
  • Dewatering fine-grained soils
  • Pressure berms

Ground Development with Structural Reinforcement
Various ground development processes are treated as form of reinforcement. Stone columns are considered as useful materials to solidify the ground. Some leading ground treatment processes are;

  • Reinforced soil
  • Soil nailing
  • Root or micro-piles
  • Slope dowels
  • Embankment piles

Ground Development with Structural Fill
To perform this, a feeble soil should be substituted with a superior quality soil. Another useful method is to apply lightweight materials in place of thicker earth fills over feeble ground. Some important ground treatment processes are;

  • Removal and replacement
  • Displacement
  • Reducing load
