Ground Improvement

Ground Improvement is used to improve the load bearing capacity of soils as an alternative to more costly structural foundation systems. MRCE has successfully implemented ground improvement to provide structure and earth support in challenging site conditions. MRCE founding Partner Daniel Moran pioneered the modern industry of ground improvement in 1929 when he invented and patented sand drains for stabilization of soft ground.

  • Ground Improvement Techniques
    MRCE engineers evaluate, select, and design ground improvement methods to address subsurface conditions and site logistics. MRCE also designs ground improvement for Contractors using their proprietary tools and methods and performs mix design and mix testing in our laboratory. Ground improvement can provide economical construction solutions for challenging site conditions and budget constraints. MRCE has experience with a full range of ground improvement techniques including:
    • Deep Soil Mixing
    • Vibrocompaction
    • Stone Columns
    • Rigid Inclusions or Controlled Modulus Columns
    • Dynamic Compaction
    • Pre-compression using Surcharge and Vertical Drains
    • Cement stabilized soil
    • Reinforced earth and GRES
  • Grouting
    Grouting can improve the strength, stiffness and water tightness of in-situ soils and rock. Proper selection of grout type and control of grout pressures and volumes are important to successful grouting without damaging adjacent structures. Grouting techniques that MRCE designs include:
    • Compaction grouting for void filling, ground improvement, and settlement compensation
    • Permeation grouting using particulate (cement / microfine cement) and chemical grouts
    • Chemical grouting
    • Jet grouting and jet grout structures for load support
    • Rock joint grouting
