Home About Us Products Customer Resources Employee Resources Afilliates Contact Us Links Rectangular Wastewater Chambers Atlantic will manufacture boxes to meet your specific needs. All are designed and manufactured to meet or exceed the most stringent industry standards. These standards include and are not limited to: AASHTO, ASTM C890, C913, and DOT requirements. Base sections and Risers are wet cast in precision steel forms. Pipe to manhole connections are placed as required. Top sections are typically cast as a slab with hatches. Vent pipes and plain holes may vary with each job’s requirements. Many options are available to our customers, including: Precast Concrete Grade Rings Grade Rings provide a means to adjust the casting to meet finish grade elevation. They are available for 24″ and 30″ diameter manhole openings and common rectangular DOT inlets. They are 2, 3, 4 or 6″ thick and stacked to the desired thickness. The contractor would lay each coarse in a bed of mortar or suitable joint material. Water-Lok Water-Lok is designed for the purpose of producing a flexible, corrosion resistant, watertight connection between castings and precast concrete cones or flat tops. They provide for grade adjustment between 0 and 14″. Bolt Slots Bolt Slot inserts are cast into a top slab or cone for the purpose of anchoring the cast iron frame to the structure. They are specified in one or two pair for each frame. Traditional anchoring systems require precise positioning to assure assembly. Bolts Slots allow more flexibility in that they allow the anchor bolt to slide in or away from the center as much as 3″. Watertight Pipe to Manhole seals manufactured by A-LOK Products, Inc. Flexible connectors are designed to produce a positive watertight connection for pipes entering precast manholes and other concrete structures. A-Lok and A-Lok X-CEL Connectors are cast in concrete at time of manufacture. They function on pure compression, making field installation quick and easy. A watertight connection is maintained with a 10 degree omnidirectional deflection. Available for pipes from 4″ through 84″ inside diameter. The gaskets meet all material and performance requirements of ASTM C923 titled, “Resilient Connectors Between Reinforced Concrete Manhole Structures and Pipes”. Z-Lok CConnectors are cast in concrete at time of manufacture and clamped onto the outside of the pipe at time of installation. A watertight connection is maintained with a 25 degree omnidirectional deflection. Available for pipes from 1.25″ through 21.25″ outside diameter. The gaskets are manufactured in accordance with the requirements of ASTM C923 titled, “Resilient Connectors Between Reinforced Concrete Manhole Structures and Pipes”. G3 Boot System Connectors provide a rubber connection for a cored or preformed hole. An expansion ring is expanded within the gasket to seal it to the concrete structure. The pipe can then be inserted and clamped. A watertight connection is maintained with a 15 degree omni-directional deflection. Available for pipes from 3.50″ through 13.5″ outside diameter. The gaskets are manufactured in accordance with the requirements of ASTM C923 titled, “Resilient Connectors Between Reinforced Concrete Manhole Structures and Pipes”. A-Lok STM – Connector for Storm Systems A flexible gasket that is designed to provide a soil-tight, as well as, watertight connection for round and elliptical pipe entering precast concrete structures. Specifically designed for application where a high performance sanitary connector is not necessary. The gasket functions on pure compression will withstand 6 psi. of hydrostatic pressure (equivalent to 13.8 ft of depth). Interior and Exterior Coatings Two component, epoxy, coatings are applied at the plant, when specified.Interior: “Ceramic White” epoxy for high performance, high build, and visibility within completed structureExterior: “Enviro-Green” epoxy for high performance, high build, and aesthetically pleasing Dura-Plate 100, interior PVC lining for corrosion protection The Dura-Plate 100 is a interior lining for precast concrete structures which combines the immense structural strength and integrity of reinforced concrete with the chemical resistance of polyvinyl chloride. The ribbed liner is integrally cast on to the interior surface of the concrete structure at time of manufacture. A structure lined with Dura-Plate 100 is assured a long service life under severe conditions, being resistant to H2S, acids, alkalis, and salts which attack sewer systems. Polypropylene or Drop Front Aluminum access rungs Manhole access is often required by use of rungs. Atlantic offers two types of rungs installed at the plant. Rungs are typically set at 12″ centers running the entire vertical height of manhole. Polypropylene Rungs: Manufactured by MA Industries Copolymer Polypropylene Plastic, 1/2″ Grade 60 steel reinforced Meet OSHA requirements Teeth and side cleats provide safe treadAluminum Rungs: Plastic step insert prevents corrosive action between concrete and aluminum Type 6061-T6 Aluminum Meet OSHA requirements Grooves and Drop front provide safe tread Butyl Rubber for joint seals D-Lok Rubber Gasket for 48″ and 60″ diameter sanitary manholes (O-Ring for larger manholes). Compression design gasket manufactured in accordance with ASTM C-443 titled, “Joints for Circular Concrete Sewer and Culvert Pipe, Using Rubber Gaskets”. Butyl Rubber for Round and Rectangular structures. Seal designed to meet requirements of ASTM C-990 titled, “Joints for Concrete Pipe, Manholes, Precast Box Sections Using Preformed Flexible Joint Sealants”. Neoprene (1″x3/4″) Gaskets are used to seal Box Culvert Joints For complete details, send an email to Atlantic Concrete. Our product catalogs and brochures are available upon request. We also offer CAD drawings of our products and a sample manhole specification on diskette for specifying engineers in some regions. Copyright© 1997-2020, Atlantic Concrete Products, Inc.
