Micropiles will often be tested in compression and pressure for verification and evidence Micro pile load capacity tests. Micropiles are more routinely designed to resist huge lateral loads, therefore, it is necessary to accomplish pre-manufacturing lateral load assessments on one piles or teams of piles too. Williams manufactures all products necessary for the reaction piles and offers a whole line of testing equipment. Compression testing is achieved by reacting from The underside of the check beam that is definitely anchored to the bottom with response piles.
