SPECIAL TECHNIQUE FOR PILE FOUNDATION IMPROVEMENT BY GROUTING

In this era of our development and reconstruction regular piles became not enough for the demands of bigger constructions, to achieve the required bearing capacity needs large diameter piles or bigger lengths relatively so that it’s difficult to execute it and having a large cost. So that several ways have been suggested to improve bearing capacity of piles and one of them is Grouting. Grouting through imbedded pipe piles considerably increase the bearing capacity, reduce settlement, and improve the property of pile-soil working together. there was a need for experimental tests for These techniques, this paper provides results of tests (12 model) on using grouting to improve bearing capacity of piles by three different techniques (three spots to grout through piles), Iraqi (karbala) sand have been used in this experiment, slurry cement used as a material grouting. Manufactured equipment used to grout, and examines the models. Results of the tests showing high improvement for both bearing capacity and settlement.
