Micropiles in many cases are analyzed in compression and pressure for verification and proof tests. Micropiles tend to be more often designed to resist big lateral loads, therefore, it's important to complete pre-output lateral load assessments on single piles or teams of piles too. Williams manufactures all solutions needed for the response piles and offers a comprehensive line of tests equipment. Compression screening is accomplished by reacting from the bottom of a test beam that is definitely anchored to the ground with response piles.
