 ProductsStorm DrainageAmericast manufactures and supplies an extensive line of storm drainage products meeting requirements of numerous governing jurisdictions. (e.g., Virginia Department of Transportation, Maryland Department of Transportation, Federal Highway Administration, District of Columbia Department of Public Works, etc.) ManholesAmericast manufactures a wide range of sizes (36”, 48”, 60”, 72”, 84”, 96”, and 120” inside diameters) to suit many applications and provide connections for various pipe sizes and configurations. Circular components, at a minimum, meet the requirements of ASTM C-478 and AASHTO M-199. Manhole StepsThe steps typically used in our precast products are steel reinforced copolymer polypropylene conforming to the following specifications:
Box CulvertAn adequate inventory of forms allows Americast to provide box culvert in single or monolithic multiple cell sections. In most cases, precast headwall and wing-wall systems are supplied with the box culvert reducing the labor costs associated with field forming and placing of concrete. Each run of box culvert is engineered to meet site specific fill and loading conditions. Detailed drawings of culvert layout are provided for each culvert system to facilitate installation of precast and related cast-in-place components. Each precast unit of the culvert system is stenciled with a unique part number that corresponds to labels on the layout details.
Culvert sections follow guidelines outlined in Virginia Department of Transportation Road and Bridge Standards and meet requirements of ASTM C-1433.
BoxesA broad range of standard sizes is manufactured for typical applications. Custom sizes or multiple chamber boxes are engineered to meet site or function specific applications. Boxes can be manufactured to serve as junction chambers or vaults for use in water, sanitary, or storm systems. Box components meet or exceed the requirements of ASTM C-858 and ASTM C-913. Drop InletsPrecast concrete tops are cast integrally with access covers and/or drainage grates when required to suit various applications. Americast produces and stocks VDOT Standard Drop Inlets.
EndwallsStraight wall or multiple face wall systems are available. Openings can be provided for single or multiple pipes and opening sizes are engineered to accommodate skewed pipes when necessary. Custom openings can be provided (e.g., rectangular weir openings for storm water management applications).
Pipe FittingsAmericast manufactures Tees, Wyes, Bends, and Reducers in the same sizes and shapes as the standard product they complement. For specific information about reinforced concrete pipe sizes and/or specifications, please contact one of the following facilities: Pond RisersPond risers are sized as necessary and engineered for site specific conditions. Care is taken to meet required safety factor for anti-flotation. In most cases, trash racks, anti-vortex devices, and/or orifice plates can be supplied with the structure. Trench DrainsTrench drains are engineered to suit each individual layout configuration. Varying lengths and depths can be provided for widths up to 24”.
Access and Inlet CastingsAmericast supplies a diverse line of manhole and inlet frames, covers, grates, hatches, and miscellaneous hardware. Castings for many jurisdictions are kept in stock enabling complete structure shipments. Custom castings or hatches meeting required specifications can be supplied or cast into precast components. Trash racks, anti-vortex devices, and orifice plates for storm water management structures can be provided to suit contract requirements. |
