Drainage

Nilex prefabricated, polymeric drainage systems (wall/strip) are available in a wide range of flow capacities, sizes, configurations and compressive strengths. They offer economical alternatives to conventional drainage systems such as french drains, chimney drains, or rock drains which consume considerably more space and use non-renewable granular materials.

Nilex drainage systems can be used in a number of different applications including retaining and foundation walls, playing fields and golf courses, bridge abutments, plaza decks and planters, Green Roofs and venting systems. Effective drainage is a critical element in road and runway construction and rehabilitation.

Vertical Drainage

In vertical drainage applications, Nilex products replace or enhance conventional aggregate drainage systems used against structures such as retaining walls, foundation walls, bridge abutments, lagging walls and soil-nailing applications.

Prefabricated drainage systems are easy to install and save money. These systems are also better for the environment by minimizing the amount of drainage aggregate processed and transported to the project site.

Nilex Nudrain WD10, WD15, WD 15(WP) and PD20
The Nudrain WD and PD series of drainage products consist of an impermeable polypropylene sheet cuspated under heat and pressure to form a high-flow dimpled drainage core.

Nilex NuDrain DN50-1
NuDrain DN50 consists of a heavy-duty, high density polyethylene geonet drainage core with ridges heat-fused to a layer of nonwoven geotextile. The geotextile retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core. DN50 is available with geotextile on one or both sides.

 

 

Horizontal Drainage

Nilex Horizontal Drainage systems are used to improve drainage and replace or reduce natural aggregate drainage materials in horizontal applications such as plaza decks, Green Roofs, patios and planters.

Prefabricated drains provide protection for waterproofing systems as well as positive drainage in the minimum amount of space (elevation) and weight, both critical elements in roof and deck applications. In planters, planting soil is retained while water passes into the drainage core and is then conveyed into the collection system.

Athletic Field Drainage

Nilex’s NuDrain series of drainage materials is available in a range of compressive strengths to accommodate varying loading conditions. Please contact us for assistance in determining a suitable material for your project.

Nilex NuDrain WD10, WD15, WD 15(WP) and PD20
The NuDrain WD and PD series of drainage products consist of an impermeable polymeric sheet cuspated under heat and pressure to form a high-flow dimpled drainage core. The core is then bonded to a layer of nonwoven (WD series) or woven (PD series) geotextile. The geotextile retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core.

Stormwater Management

Nilex Stormwater Chamber Systems act as replacements for ponds, concrete structures or pipe and stone installations in the management and absorption of natural stormwater.

Stormwater Chambers

In undeveloped areas, rainwater is unrestricted and can be readily absorbed directly into the ground. When an area is developed, buildings and parking areas offset the natural absorption pattern, preventing rainwater from penetrating the ground often resulting in ponding or flooding.

The placement of Nilex Stormwater Management Systems beneath parking areas maximizes land use and parking capacity. Nilex Stormwater Chamber Systems can also be used to control roof and driveway run-off by eliminating ponding and allowing for alternative land use.

Nilex Stormwater Chambers
Nilex Stormwater Chambers protect environmentally sensitive areas and ensure a more controlled infiltration of rainwater. These products are an economically and environmentally beneficial alternative to traditional retention ponds.

 

Recreational & Landscape Drainage

Nilex drainage products are often used in recreational and landscape drainage applications as economical and environmentally friendly options to conventional aggregate drains such as French or trench drains.

Athletic Field Drainage

Nilex offers several types of strip drain configurations to suit a variety of applications including roads, playing fields and golf courses, venting systems, and other applications requiring chimney or rock drains.

Nilex NuDrain materials provide significant cost and environmental savings by minimizing the amount of spoil material that is excavated and transported from site and the amount of drainage aggregate processed, transported and placed on site.

Nilex NuDrain strip drains consist of an expanded polymer core encapsulated by a highly permeable geotextile wrap. This design provides an effective, economical alternative to the conventional aggregate drain and filter structures. Significant savings are found in the excavation of a narrower trench and the reduction in importing drainage aggregate means lower cost and the reduced use of a non-renewable resource.

Multi-Flow Strip Drain
Used in a variety of drainage applications, the Multi-Flow systems features round drainage channels that provide a large surface area for water collection and a highly efficient means for moving excess water from saturated soils. The Multi-Flow system includes connectors, tees and other fittings to facilitate installation.
