Deep Foundation Engineering
Pile Foundations & PDA Testing
Deep foundation design and PDA testing for projects where conventional foundations won't do. Engineered for BC conditions.
When You Need to Go Deeper
Pile foundations are deep structures that transfer building loads through weak surface soils to deeper, more competent materials. Coast Geotechnical provides pile foundation design and Pile Driving Analyzer (PDA) testing for residential, commercial, and infrastructure projects across Western Canada where shallow foundations are inadequate due to weak soils, variable conditions, or high structural loads.
We work with driven steel piles, helical piles, drilled piers, and timber piles, selecting the appropriate system based on soil conditions, structural loads, and site constraints.
PDA testing provides quality assurance during pile driving, confirming installed pile capacities without the cost of full-scale static load testing.

How It Works
Subsurface Assessment
We evaluate subsurface conditions through drilling, CPT, or existing investigation data to determine suitable pile type and estimated capacity.
Pile Design
Our engineers prepare pile foundation designs with sealed drawings and capacity calculations, coordinated with the structural engineer of record.
PDA Testing & Monitoring
Our engineers attend pile driving to conduct PDA testing and verify installed pile capacities, delivering sealed reports with capacity results for each tested pile.
