Borehole Log Template

Use the Borehole Log Template to record details of boreholes, including depth, geology, water levels, and other key details for accurate geotechnical data.

1. What is the borehole location (coordinates or site address)?

2. What is the date and time of drilling?

3. Who conducted the drilling and logging?

4. What is the purpose of the borehole?

5. What is the borehole ID or reference number?

1. What drilling method is being used?

2. What is the borehole diameter?

3. What is the total depth drilled so far?

4. What are the drilling start and end times?

5. Were there any difficulties encountered during drilling?

1. What type of soil or rock is encountered at each depth interval?

2. Are there any visible layers, strata, or changes in material?

3. Are color, texture, and moisture content recorded for each layer?

4. Are any groundwater strikes noted during drilling?

5. Are any unusual features, such as boulders or voids, observed?

1. At what depth is the water table encountered?

2. Is there continuous water inflow, seepage, or artesian flow?

3. What is the water quality (if tested) at different depths?

4. Are water levels recorded periodically during drilling?

1. Are samples collected at specified depth intervals?

2. Are samples labeled, stored, and logged correctly?

3. Are standard tests performed on the samples (e.g., grain size, Atterberg limits)?

4. Are sample conditions noted (disturbed, undisturbed, moisture content)?

1. Is casing installed according to design specifications?

2. Are borehole markers and reference points correctly placed?

3. Are all safety protocols followed during drilling and logging?

4. Are hazards or unusual conditions noted for future reference?

1. Are any anomalies, blockages, or obstructions noted?

2. Are field notes and measurements recorded accurately?

3. Is any additional information or observations relevant to the borehole documented?
