Combined installation and material cost is typically less than half the cost of aggregated drains.
|
Lightweight (less than 5 oz / sf), easy to handle sheet drain is placed easily and quickly. No heavy equipment or skilled labor required. Inexpensive to store and transport.
|
By design, the flow capacity of thin, lightweight prefabricated drains far exceed that of several feet of stone.
|
Core thickness ranges from 1/4” – 1” and reduce the amount of excavation required to install aggregate systems.
|
The open area for water collection in prefabricated drains is 65-80% vs. 3-5% in perforated pipe. This allows for faster and higher volume water collection in below grade applications, making prefabricated drains a better and more efficient solution for sub-surface drainage applications.
|
Filter fabrics permit high volume water entry while retaining fine soil particles. Filtration properties combined with a large percentage of open area for water collection reduce clogging and the possibility of drainage failure.
|
Prefabricated drains are engineered to meet uniform and independently verified performance characteristics insuring predictable field performance.
|
Prefabricated drain core and filter fabrics are resistant to all naturally occurring soil properties. Additional product choices are available for unique chemical conditions.
|
Crush strength of core resists damage during installation. High tear and puncture strength of fabric ensures no damage during normal backfill conditions.
|
Visual inspection of material an installation is easy and less time consuming.
