NDS gravel free French Drain products can be used as a substitution for a traditional gravel French drain. They consist of fabric, lightweight gravel substitute, and pipe all in one package. The NDS French drain can be installed anywhere a traditional French Drain can is installed plus areas where access is limited or heavy gravel can't be easily installed. A few of the many applications are: landscape drains, roof run-off drains, basement or crawlspace dewatering, retaining wall drains, foundation or perimeter drains, interceptor drains, and curtain drains.
The NDS French Drain is a prefabricated trench drain that is a gravel free option to a traditional French drain. It cuts installation time in half by eliminating the need to transport, shovel and move heavy gravel. It is made of 3 or 4 slotted corrugated pipe, surrounded by NDS poly-rock, and wrapped in a geotextile fabric. It's durable, crush-proof and has a 100-year lifespan. The NDS French Drain has been designed to take water out of the soil and pipe it to a safe discharge point like an NDS Flo-Well or Pop-Up emitter.
Polyrock aggregate is engineered with flow channels to increase void space and is made out of polystyrene which does not absorb water or break down in water or other aqueous solutions Comes with slotted pipe or aggregate only bundle
EZflow® drainage systems are appropriate for a wide range of applications and are a convenient alternative to traditional stone and pipe drainage, storage and infiltration systems. EZflow® drainage systems can be used as a substitute for stone in most applications where the stone is not utilized for structural support. A professional engineer, landscape architect or other qualified design professional should be consulted for complex applications. Product selection is relative to the desired application and benefits from establishing anticipated flow into, through and out of a proposed drainage system configuration. Selection considerations include: bundle sizing and storage volume, the presence or absence of pipe, pipe size and location within the bundle, and arrangement of bundles. Design factors may include: length of system, watershed area, soil type and permeability, groundwater levels and system discharge opportunities.
