French Drain & Drainage Materials

French Drain & Drainage Materials

When the Norfolk County clay finally drains in late March, you find out exactly which corner of the yard the water has been sitting in all winter. A French drain only works if the trench is wrapped in clean, washed stone and the right bedding sand — fines clog the perforated pipe and you’re back to a swamp by April.

This collection groups the bulk drainage materials Ottr keeps on the yard year-round:

  • Gray Crushed Rock ¾" and 1.5" — washed, drainage-friendly aggregate sized for #57-style French drain fill and dry wells.
  • Blue Stone Rock ½" and ¾" — an alternative drain stone where homeowners want a grayer, more uniform aesthetic at the trench cap.
  • Blue Stone Dust (fines) — bedding under filter fabric and pipe.
  • Coarse Sand — foundation course on bony native soils where you need to seat the fabric flat before stone goes in.

Coverage rule of thumb: one cubic yard of drainage stone fills roughly 27 linear feet of a 12"-wide x 12"-deep trench, or about 18 linear feet at 12" x 18". Add 10-15% for compaction and waste on residential pulls.
