COMPACTION
Dynamic compaction is a method used to increase the density of the in situ soils and to improve the load bearing capacity of the ground. The process involves repeatedly dropping a 12-tonne weight at predetermined grid pattern to achieve the required energy input.
WHAT THEY’RE USED FOR
Dynamic compaction is a highly sustainable ground improvement technique which produces zero spoil. This method can be used for the treatment of industrial warehouses, port and airport platforms, roads and railway embankments, heavy storage tanks, nonorganic heterogeneous fill or obstructed sites, and soils that are susceptible to liquefaction.
This method is extremely economical and is ideal for large sites where obstructions preclude vibro techniques.
THE PROCESS
The 12000 series drop weights are interchangeable and special shaped weights can be used depending on the application and site-specific ground conditions.
The ground is repeatedly subject to ground tamping using a heavy concrete weight, from a controlled height of up to 12 metres high at predetermined grid pattern. Typically, the ground is treated between two to five passes depending on the ground conditions.
WHY USE Dynamic Compaction (NRG)?
High production rate
Ideal for contaminated or obstructed sites
Alternative to vibro techniques
Reduced settlement
Increased bearing capacity
Improves soil conditions and strength
