BS EN 12715 applies 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 BS EN 12715:
The principal objectives of geotechnical grouting are:
Note 1: Specialized grouting activities, generally associated with structural and/or emergency works, are not covered by BS EN 12715.
Note 2: The term consolidation grouting is sometimes used to emphasize an improvement in the strength or deformation characteristics of a soil or rock mass, aiming to not undergo any unacceptable deformation. The term compensation grouting is used when the objective of grouting is to concurrently compensate for the ground loss.
BS EN 12715 on the execution grouting is relevant to:
Grout is usually a mixture of cement, sand, and water or chemicals that are used to fill gaps.
BS EN 12715 provides coverage of the construction and supervision requirements for grouting works. BS EN 12715 specifies the execution design for geotechnical grouting applications, including grout materials, pressures, flow rates, sequence, and spacing.
This can assist you in receiving and implementing services that strictly conform to international standards and rules that can maintain the structural integrity of engineering works. Overall, you can efficiently control seepage, groundwater flow and hazardous waste material, with BS EN 12715 compliant best industry guidance.
