Most developable property available today has undesirable subsurface conditions. These sites require modification to render them suitable for development. GTA has extensive experience in ground modification design, having worked on difficult projects throughout the region. Ground modification techniques are used to improve the structural support qualities of an otherwise unsuitable material. These techniques provide cost effective alternatives to conventional over-excavation and replacement methods.

GTA's areas of specialization are as follows:

• Site characterization
• Compaction grouting
• Lime and cement stabilization
• Stone columns
• Deep-dynamic compaction
• Geo-synthetics
• Chemical grouting
• Surcharging/wick drains
