Perforated drainage pipe, also called weeping tile, is primarily used for home drainage systems. It is located along the footing and around the inner and outer edge of the home. Weeping tile provides advantages like being lightweight, corrosion resistant, and unaffected by freeze-thaw cycles. However, it can become clogged over time and be difficult to clear. Weeping tile is installed by digging a trench, laying gravel, placing the pipe, and backfilling the trench. Proper compaction of the backfilled soil is important to prevent issues with the drainage system over time.

BACKFILL AND COMPACTION
“ Backfill and compaction are essential for safeguarding the
pipeline against the internal and external stresses it
experiences during its service life.”

• Area to be backfilled has been
inspected
• Pipes have been installed in accordance
