Many projects require ground modification to meet development objectives or to allow construction progress.
We can assist your development team by designing and implementing numerous ground improvement engineering techniques, including:
Lateral earth support (LES) is often required with subsurface site development to:
GeoInsight staff members have consulted on and designed numerous complex LES systems, many in congested urban locations. Our design experience includes numerous temporary and permanent retention techniques, such as:
Often, existing structures require additional support because of actual or potential foundation movement due to excessive settlements or proposed excavation. GeoInsight is familiar with numerous techniques to shore up existing features with piles, cast-in-place concrete underpinnings, and grout. We can identify economical solutions to address proper support of existing foundations and slabs damaged by settlement or movement. We can design underpinning systems and sequences to transfer foundation support to a deeper layer, thereby allowing vertical excavation to occur directly adjacent to an existing foundation.
Projects with cuts into existing natural or constructed slopes usually require slope stability analysis. These assessments may be focused on large-scale slope failures, smaller failures within the slope itself, or sliding of the slope layers. GeoInsight has performed numerous slope stability evaluations associated with:
We provide recommendations and designs for slope stability monitoring and improvement, including:
GeoInsight personnel have recommended and designed numerous weak-ground improvement programs including:
We can help you evaluate your densification objectives, and the costs involved, increasing your available options and making an unwelcome site attribute become viable for development.
Often, the most cost-effective solution for your site improvement needs involves over-excavation of existing unsuitable soil and replacement with structural soil, lightweight fills, or aggregate with special properties. We have applied this methodology to hundreds of sites and have a high degree of expertise supporting simple foundation systems. When possible, our assessments include the reuse of existing soils in compacted lifts (with or without mixing with other soils), creating a stable subgrade to support foundations while minimizing the need to import soils.
We test existing site soils as well as material from borrow pits or processors to identify the materials or material blends that will meet the soil support recommendations. We also provide field oversight of installation to ensure that compaction requirements are met.
Geosynthetics are a popular construction material as owners, regulators, and designers gain familiarity with the capabilities, cost savings, and sustainability aspects associated with their use. GeoInsight evaluates, recommends, designs, and installs many types of geosynthetics, including:
When water velocity and ground cover are incompatible, erosion can occur. This is especially common during construction, when soils are exposed and controls are needed to comply with storm water regulations. We design practical solutions that are economical, effective, and tailored to your site. Slope armor and erosion solutions include natural and synthetic erosion control blankets, vegetated slopes, rip rap armor, and sloping and mulching.
Our Certified Professionals in Erosion and Sediment Control have prepared many different types of Erosion and Sediment Control Plans. We are familiar with the application, design, and construction of Best Management Practices used to control storm water. We keep abreast of innovative technologies employed for these purposes, and are familiar with performance data and manufacturer’s literature. Our experience and library of templates will result in significant cost and time savings for your project.
