Abstract
The grouting under the base of bored pile is carried out in order to reduce pile settlement and improve its bearing capacity. The principal aim of grouting is to introduce an initial force between the soil and the pile base. In non-cohesive soil, the grouting can also enlarge the pile base area and therefore improve the base resistance. The example of static load tests on instrumented bored piles installed with and without grouting is presented. The interpretation and comparative analysis of both piles tests is carried out and gives interesting results. The conclusion of analysis is, that the grouting under the base primarily activates and increases the pile shaft resistance and thanks to it improves the characteristics of bored pile interaction with soil.
