Foundation Investigation and Design

Service Overview

GeoStructures understands the various factors that can contribute to costly foundation expenses, which is why we aim to develop technically-sound support systems while minimizing project costs with innovative and practical solutions. From standard services to soil-structure interaction modeling and comprehensive foundation design and inspection, our services encompass all types of support systems and load testing.

Optimum foundation designs do not naturally arise from equations or design charts; they are a product of outstanding engineering judgment developed through years of experience in the design and construction fields. When multiple foundation types seem equally feasible, selecting the best system for the job can be challenging but also very rewarding. Responsible design optimization requires us to look beyond subsurface investigations and routine cost estimates.

Our engineers are skilled at asking the right questions about site grading, construction sequencing, scheduling, abilities of local construction forces, and other project-specific variables that could affect design or construction of a foundation.

Service Offerings

Shallow Foundations

Design and inspect shallow foundations, such as spread footings and slab-on-grade, to ensure they provide stable and cost-effective support for structures.

Mat Footings

Develop mat footing designs for large and heavy structures, distributing loads across a wide area to enhance stability and minimize settlement.

Driven Piles

Implement driven pile solutions, using steel, concrete, or timber piles driven into the ground to support structures in challenging soil conditions.

Drilled Piles

Design and inspect drilled piles, where holes are drilled into the ground and filled with concrete, providing deep foundation support for various structures.

Jetted Piles

Utilize jetted piles, employing high-pressure water jets to assist in driving piles into dense soils, ensuring proper installation and load-bearing capacity.

Bored Piles

Design and implement bored piles, involving drilling and filling with concrete, to provide strong and stable foundation support for heavy loads.

Auger Cast Piles

Develop auger cast pile solutions, using continuous flight augers to create deep foundations that are filled with concrete as the auger is withdrawn.

Precast Piles

Design and install precast piles, made of precast concrete, providing high-quality and consistent foundation support for various construction projects.

Cast-in-Place Piles

Implement cast-in-place pile solutions, where concrete is poured directly into drilled or driven shafts, ensuring custom fit and strong foundation support.

Drilled Piers or Caissons

Design and inspect drilled piers or caissons, deep foundation elements drilled into the ground and filled with concrete, offering robust support for large structures.
