This document is applicable to the execution, testing and monitoring of geotechnical grouting work.
Grouting for geotechnical purposes (geotechnical grouting) is a process in which the remote placement of a pumpable material in the ground is indirectly controlled by adjusting its rheological characteristics and by the manipulation of the placement parameters (pressure, volume and the flow rate).
The following principles and methods of geotechnical grouting are covered by this document:

The standard comprises requirements for ground investigations by means of the field vane test (FVT) as part of the geotechnical investigations.

This document deals with the equipment requirements, execution and reporting of field vane tests for the measurement of peak and remoulded vane shear strength together with the sensitivity of fine-grained soils. In addition, post-peak shear strength behaviour can be evaluated. Two types of field vane test are described: the ordinary field vane test (FVT) and the fast field vane test (FVT-F). The uncertainties of the vane test result are described in Annex D. NOTE 1 This document fulfils the requ...view more

This standard forms part 4 of the series ISO 18674, as described in ISO 18674-1: Part 1. General rules the methods and gives rules for measurement of pore water pressures in geotechnical engineering or more general in foundation engineering. Pore pressures are needed to obtain effective stresses and play a key role in the analysis of engineered construction in and on ground.

This document specifies the measurement of pore water pressures and piezometric levels in saturated ground by means of piezometers installed for geotechnical monitoring. General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674‑1. If applied in conjunction with ISO 18674-5, the procedures described in this document allow the determination of effective stresses acting in the ground. ...view more

This standard forms part 5 of the series ISO 18674, as described in ISO 18674-1: Part 1. General rules the methods and gives rules for measurement of total stresses  in geotechnical engineering or more general in foundation engineering. Stresses in soil or rock  are needed to judge the loading of engineered construction in the ground.

This document specifies the measurement of stress changes by means of total pressure cells (TPC). General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674‑1.
If applied in conjunction with ISO 18674‑4, this document allows the determination of effective stress acting in the ground.

in the laboratory for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.

This European Standard applies to the treatment with binders of natural soils, weak and intermediate rocks (including chalk), recycled materials and artificial materials for the execution of earthworks during the construction and maintenance of roads, railways, airfields, platforms, dykes, ponds and any other types of earth structure.
It relates only to the treatment by layers for earthworks, as opposed to the treatment by columns for example.
The standard specifies the requirements for the cons...view more

This European Standard deals with underwater excavation and hydraulic placement of fill material for land reclamation projects providing structural support. The main focus is on soils that exhibit drained behaviour during and after placement.
