Soil Stabilization

EDP Consultants provides complete engineering, laboratory testing, technical support, and monitoring during construction for chemical soil stabilization projects. Chemical soil stabilization can improve strength, plasticity, permeability, shrink-swell and other soil properties. We specialize in the determination of economical mix designs and evaluating the characteristics of the stabilized soil mixtures. The result is a stabilized subgrade engineered to meet the project’s specific performance needs and criteria.

Engineering and laboratory services:
Subsurface Exploration
Mix Design
Untreated Material Evaluation
Evaluation of Stabilizing Agents
Maximum Dry Density Determination
Moisture Conditioning
Soil-Cement Cylinders
Compressive Strength Determination
Determination of Required Field Application Rate

Field services:
Subgrade Evaluation
Monitoring During Construction
Monitoring Chemical Admixture Application
Moisture Control Verification
Re-Evaluation of Maximum Dry Density
Field Sample Preparation
Compaction Testing
Construction Monitoring Services

EDP Consultants' construction monitoring staff is experienced in all construction related areas. The technical staff is supported and supervised by professional engineers that are always available to assist in solving field problems. Field problems are resolved promptly and appropriately allowing construction to continue on schedule without wasted motion or unnecessary extras. This reduces delays and saves money.

EDP Consultants plays an important roll as a member of the project team by assisting the contractor to get results, to stay on schedule, and to provide the final product that the owner has specified and therefore demands. Because we provide strong engineering support, we can assist the owner and other design professionals in evaluating problems and finding solutions that are both cost effective and practical.

Testing services offered:
Earthwork, concrete, asphalt, masonry
Pile foundations: driven, augered, drilled
Shallow foundations
Reinforcement
Floor slab flatness testing
Ground improvement

Full Scale Testing and Special Projects

EDP Consultants will design and conduct special testing programs to meet the clients individual project needs. From large, full scale load tests, to highly specialized testing programs to evaluate recycled materials and architectural or structural building elements, EDP Consultants can provide a program to fit any project requirements. Past projects have included full scale load testing of pile and drilled pier foundations, testing of steel and timber structural members, evaluation of soil amendments, stabilization and recycling of industrial byproducts, new and experimental asphalt materials, and more.

Testing programs are provided for:
Design verification
Evaluation of historic structures
Strength determination to reduce construction cost
New material applications
Load rating of damaged or deteriorated structures
Performance of composite materials
