On average, a geotechnical report costs between $1,000 and $5,000, with most homeowners spending an average of $2,700. A basic test can run as little as $150 per sample, while a full geotechnical survey can top $5,400. The main cost drivers are the size of your test area, the type of testing you need, and labor costs.
Geotechnical Report Cost Factors
The cost of soil tests depends on on-site test labor, lab fees, and other factors. Here’s a closer look at how your costs break down.
Labor
Hiring a licensed local soil engineer, geotechnical engineer, or geologist costs $100 to $250 per hour for fieldwork, sampling, and on-site consultation. Your final price depends on the test type, the number and depth of samples, site access, and their travel time.
Area Size
Lots of similar sizes cost about the same to test. Larger sites, however, need extra samples to capture accurate soil conditions. An oil-tank check focuses on a small footprint, while a multi-acre farm often requires broader sampling across the property.
Soil Remediation
If your soil test results point to contamination, nutrient gaps, or weak structure, you’ll need remediation next. The method you choose—whether amending nutrients or removing contaminants—along with the scale of the work, drives the final price.
Cost by Test Type
The biggest driver of price is the kind of test you order. Routine checks cost less, while specialized construction reports can climb past $1,750.
| Test Type | Purpose | Average Cost |
|---|---|---|
| Soil compaction | Measures soil density and structural strength | $190–$350 |
| Soil percolation | Required for septic systems; measures absorption and drainage | $250–$850 |
| Advanced composition | In-depth analysis of minerals, elements, and overall makeup | $300–$1,750 |
| Soil boring | Extracts soil 15–20 feet underground to assess construction suitability | $750–$1,500 |
Budgeting for Soil Testing
Accurate soil data starts with a high-quality test. Skimping here often leads to expensive fixes down the road. To get the most value:
Gather quotes from at least three soil-testing firms.
Hire contractors who specialize in the exact test you need.
Ask about bundling testing with amendment or aeration work to trim travel fees.
Order only the tests your project truly requires.
How HomeAdvisor Gets Its Cost Data
No place is more important than your home, which is why HomeAdvisor connects homeowners with local pros to transform their houses into homes they love. To help homeowners prepare for their next project, HomeAdvisor provides readers with accurate cost data and follows strict editorial guidelines. After a project is complete, we survey real customers about the costs to develop the pricing data you see, so you can make the best decisions for you and your home. We pair this data with research from reputable sources, including the U.S. Bureau of Labor Statistics, academic journals, market studies, and interviews with industry experts—all to ensure our prices reflect real-world projects.
Timelines for soil tests vary depending on the type of test and its analysis process. Availability for on-site testing, consultations, and labs also affects how long it takes to get results back. In general, more complex or in-depth soil tests take longer to complete.
Soil testing is a valuable investment for many homeowners. Tests generally contribute to a project's success by identifying potential issues, such as structural issues or unbalanced nutritional profiles. Some local regulations require these tests to obtain building permits and may fine sites that fail to satisfy inspection and testing guidelines.
The best method for soil testing is the one that’s aligned with your goals. Soil tests provide insights into different soil characteristics and are consequently suited to certain projects and goals. For example, basic soil profiles and garden and lawn soil tests provide nutritional insight and help inform topsoil needs, amendments, and plant selection.
