Micropiles are sometimes examined in compression and pressure for verification and evidence tests. Micropiles are more routinely designed to resist huge lateral loads, hence, it is necessary to conduct pre-creation lateral load checks on single piles or groups of piles likewise. Williams manufactures all goods needed for the response piles and provides a total line of tests equipment. Compression testing is completed by reacting versus the bottom of the test beam that may be anchored to the ground with reaction piles.
The timber pile foundation on the century-aged Prairie du Sac Dam was deteriorating due to historic tailwater recession. Micropiles have been put in in many different different combinations to remediate the dam's foundation.
