TIPS ON INSTALLATION OF CORRUGATED STEEL PIPE
Preparing the bedding
Corrugated steel pipe can be installed successfully only on a properly
prepared bedding. The bedding should offer uniform support to the pipe and help seat the corrugations in the underlying soil.
Frozen soil, sod, large rocks or other similar objects must be removed from the bed.
Backfilling
All suitable structural backfill materials will perform well with
corrugated steel pipe. However, backfill should be free of large stones, frozen lumps and other debris. Backfill materials
should be placed in layers about six inches deep, deposited alternately on opposite sides of the pipe. Each layer should be
compacted carefully. Select backfill is placed and compacted until minimum cover height is reached.
