Hundreds of productive acres-days are lost every
year due to poor drainage in athletic fields, tracks, yards, golf
courses, and crop lands. Additionally, poorly draining driveways,
tennis courts, and pavements loose their structural integrity quickly,
causing surface cracks, depressions and failures. Poor drainage
can also cause lawns and plants to die from root disease. Manufacturers
and practitioners don't discuss it much but we estimate that more
than half of underground drainage systems become useless or only
marginally effective within one year of installation. This is usually
due to four common factors that are often working together:
- Collection/conveyance systems, are undersized
- Collection/conveyance systems are damaged during
installation or backfill & compaction
- Collection/conveyance systems are at improper depth,
elevation or location
- Collection/conveyance system blinds or clogs.
TME has gone to great lengths to research the
principles and practices relating to underground drainage and has
achieved an excellent understanding of how and when to apply modern
technology in the right places. In order to install a drainage system
that works every time for years to come, we look at elements that
are almost always ignored by others. This includes soil analysis,
surface runoff coefficient, runoff volume, surface area, surface
type (grass, pavement, etc.), the availability of primary filtration
materials for trench backfill, grades, and outfall locations. This
information tells us how deep and large to size the trench and what
size and type of collection/conveyance system to use.
