| 20110200391 | Stormwater containment assembly and associated end section - An end section or cap for a stormwater containment assembly includes a substantially half-dome-shaped body member and a connector disposed on the body member along a periphery or perimeter thereof, for coupling the body member to a stormwater chamber wall. The body member has a smooth convex outer surface with an absence of reinforcement ribs and also has a smooth concave inner surface with an absence of reinforcement ribs. | 08-18-2011 |
| 20090075004 | APPARATUS AND METHODS FOR CROSS-LINKED CORRUGATED POLYETHYLENE PIPE - A composition and method for a single or dual wall extruded and thermoformed pipe corrugated HDPE pipe composed of a thermoplastic HDPE that is subsequently cross-linked by introducing moisture. The typical thermoplastic HDPE utilized for blow molding to fabricate the corrugated pipe is cross-linked to enhance dimensional stability, stress crack resistance, impact, creep resistance, and stiffness. The method also may comprise obtaining the enhanced properties by cross-linking the already fabricated linear HDPE corrugated pipe. The cross-linked HDPE is produced using a silane processing method. A composition may comprise a high density polyethylene compound composed with about 1 to 15 percent of finely ground isotropic cross-linked polyethylene recycle. | 03-19-2009 |
