As increasing yields necessitate expansion in grain storage and drying capacity, Helitech Civil Construction Division is here to ensure your grain system will stand for generations to come.
As grain towers reach higher into the sky, the loads they place on the ground magnifies. If the soil beneath the bin is too compressible or has relatively low strength characteristics, it can spell disaster.
Helitech offers a wide range of solutions to meet project demands and soil condition requirements including: Aggregate Piers (also called Vibratory Stone Columns, VSCs, or aggregate piers), Vibratory Concrete Columns (VCCs), Controlled Modulus Columns (CMCs), and Auger Cast Piles.
For many soil conditions, the most cost effective ground improvement solution for today’s agriculture industry are Aggregate Piers.
Aggregate Piers are a ground improvement technique where dense columns of compacted stone are constructed to increase bearing pressures in areas of soft soils. Additionally, Aggregate Piers are used to mitigate settlement under structural footings. The aggregate piers are designed and installed in groups to improve the ground’s ability to support structures.
Helitech CCD has the expertise to design and construct a cost-competitive ground improvement plan to greatly improve the bearing capacity and settlement performance of the site.
For projects with tighter settlement tolerance, Vibratory Concrete Columns (VCCs) or Controlled Modulus Columns (CMCs) can be used to improve the underlying soils.
VCCs and CMCs are forms of ground improvement similar to Vibratory Stone Columns (VSCs). The difference being Concrete Columns are constructed more rigidly to further reduce the settlement characteristics of the underlying soil.
As both CMCs and VCCs are more rigid, these systems will require a load transfer platform consisting of several feet of crushed stone in order to transfer the loads.
Helitech CCD also offers conventional Auger Cast Pile type foundations for projects with strict settlement tolerances.
