What is ISO 22282-1-Rules for geohydraulic testing about?
ISO 22282-1 establishes the general rules and principles for geohydraulic testing in soil and rock as part of the geotechnical investigation services in accordance with EN 1997-1 and EN 1997-2. It defines concepts and specifies requirements relating to permeability measurement in soil and rock.
Note: Geohydraulic testing for water supply is covered by ISO 14686.
Note: For most types of ground, field permeability tests yield more reliable data than those carried out in the laboratory, because a larger volume of material is tested, and because the ground is tested in situ, thereby including effects resulting from the structure of the groundmass but avoiding the disturbance associated with sampling.
Who is ISO 22282-1- Rules for geohydraulic testing for?
ISO 22282-1 on geohydraulic testing is useful for:
- Geotechnical investigation and testing
- Geotechnical contractors and consultants
- Hydrogeologists
- Civil engineers    
- Geotechnical engineers
Why should you use ISO 22282-1- Rules for geohydraulic testing?
Geotechnical testing is carried out by geotechnical engineers, geotechnical technicians, or engineering geologists to determine the features of a worksite, such as the physical attributes.
The different purposes of geohydraulic testing are to obtain information on the permeability of soil or rock in natural or treated states, transmissivity and storage coefficient, and hydrodynamic parameters of aquifers.
Geohydraulic testing is used for many purposes, such as:
- Absorption capacity and effectiveness of grouting in rock mass
- Assessment of seepage and drainage
- Assessment of groundwater lowering work
- Effects of cut-offs for dams
- Effects of tunnels and shaft sinking
- Checking fill or cover tightness
- Assessment of the flow of fluids and suspensions in the ground
- Planning for remedial measures
The objectives of ISO 22282-1 are to establish the groundwater conditions, to determine the hydraulic properties of the ground, and to gather additional relevant knowledge about the site.
Overall, ISO 22282-1 can help you achieve accurate geological and hydrogeological information and data. This is crucial in managing project risks, both identified and projected, as well as the risks of accidents, delays, damage, and pollution.
