Evaluating seepage conditions for construction stability.
Invest in the official standard from BSI or ISO. Then, cross-reference it with practical field guides. Your projects—and your professional reputation—depend on getting permeability testing right.
: Maintaining a constant pressure head and measuring the resulting flow.
In a constant head test, water is injected into or pumped out of the borehole at a rate that keeps the water level perfectly stationary.
The following is a summary of a typical field testing campaign in accordance with BS EN ISO 22282‑2:2012, based on a real project example from the Lower Thames Crossing in Essex, UK: bs en iso 22282-2 pdf
The introduction of the BS EN ISO 22282 series marked a major change in UK geotechnical practice. It replaced the testing methods that had previously been covered by the withdrawn British Standard BS 5930. The publication was described by the BSI director of publishing as “critical to the geotechnical industry” because the relevant testing sections of BS 5930 have now been formally withdrawn.
A standard-compliant investigation requires two distinct reports:
BS EN ISO 22282-2 outlines three primary methods for measuring permeability ( ) based on the ground's expected flow characteristics: : Best for : Higher permeability soils (typically
BS EN ISO 22282-2 is a joint British, European, and International standard. The title breaks down as follows: Evaluating seepage conditions for construction stability
Specifications for ensuring the hole is stable and properly prepared.
Buy it if you’re legally required to follow BS EN standards. For reference only, a library copy or preview might suffice. The technical content is excellent, but BSI’s PDF formatting lags behind modern e-documents.
: Specifies the equipment needed, the preparation of the borehole, the execution of the test, and the required data for reporting results. Where to Find the Document
: Defines applicability for geotechnical investigations under EN 1997-1 and EN 1997-2. The following is a summary of a typical
To ensure accuracy, the standard mandates specific equipment standards and calibration protocols:
: Pumping water in at a steady rate to see how much the ground can "drink".
The standard defines the procedures for measuring the hydraulic conductivity of soil and rock. Unlike Part 3 (which covers pressure tests in closed systems like packers), Part 2 focuses on open systems
