Features and benefits

Inexpensive Installation
The product is lightweight and easily handled which translates into faster installation with less equipment and personnel, which results in a lower total cost.

Field Adjustments
Drain basins are easily adjustable in the field to meet final grade. Last minute trimming or extensions are easily made to insure proper positive drainage is achieved.

Watertight Connection 
Structures are shipped with rubber gaskets to ensure a watertight connection. This prevents the soil infiltration that plagues precast (or “traditional”) structures and prevents long-term settlement around the basin.  

Flexible Resilient Connection 
The real world can be tough on underground structures. Soils consolidate unevenly and external loads can further complicate matters. Flexible connections allow minor movement to take place without compromising the structural or watertight integrity of the basin. Additionally, the need to wait for grout to set-up is eliminated. With Nyloplast, you can connect and backfill immediately. 

Large Size Castings for Peak Water Capacity
Nyloplast Curb and Road & Highway castings were designed for maximum water removal in paved and heavy traffic areas. Our Nyloplast inlets have been designed to meet drainage area design parameters specific to your project with variable grate openings and heavy-duty traffic rated ductile iron castings. Perfect for all types of pavement and roadway applications.
