How can you – as a home owner – be assured that once we install our piers that they will never move? We install permanent bench marks at each pier installed. In most cases they are drilled in the brick veneer or siding. The theory is that these bench marks are not all going to move simultaneously, even with settling … and the one that does will be verified by the laser shot with the transit. The pin locations are noted on our original drive logs which will be recorded during the installation pile.
