How can you – as a homeowner – be assured that once we install our piers, that they will never move? We install permanent benchmarks as each pier is installed. In most cases, they are drilled in the brick veneer or siding. The theory is that these benchmarks are not all going to move simultaneously, even with settling … and if one does move, it 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 process.
