Projects
Rock Valley Storm Sewer Job
A-LOK STM connectors were used for this watertight storm sewer job in Rock Valley, Iowa. The precaster showed the engineer pictures of two other STM box jobs he did in the past year. The engineer liked the idea and convinced the city to use them. Compression style watertight connections were made to accommodate the following sizes of pipes: 8” PVC, 15”, 18” 24”, 36” and 48” RCP. All were cast into square structures with sizes ranging from 2’x2’ to 6’x8’ inside. The city of Rock Valley now has written storm water specifications for watertight pipe penetrations in boxes using A-LOK STM connectors.

Langer Connection
In Kennedy Township near Pittsburgh, PA manholes installed in the late 70's were being attacked by Hydrogen-Sulfide gas, releasing a terrible odor. Twelve new manholes were lined with our Dura-Plate 100 Liners to resist corrosion and outfitted with our Z-LOK connectors to create a watertight structure. Each Dura-Plate Lined manhole was set and connected to the existing clay pipe in about 20 minutes. The smell of raw sewage is gone from this beautiful area of Kennedy Township. Herbert Run
In Lansdowne, Maryland the objective was to replace old, leaking brick manholes. The contractor called and explained it was taking too long to connect the pipe to the connector. After a visit to the job site, we discovered the sharp edge of the pipes were not beveled, which made it hard to push the pipe through the A-LOK connector. After beveling, the installation was completed within fifteen minutes. The shorts were installed above ground, the manhole was lowered into the trench and the connection was made with existing pipes.Quemahoning Water Transmission Line
The goal of this project was to obtain more drinking water for Johnstown, Pennsylvania. Above is a picture of the 60'' riveted iron pipes that used to carry water to Johnstown. This job consisted of twenty-two miles of new pipe to transport the 5.75 billion gallons of water from the dam. Most of the one hundred manholes from the job were outfitted with our X-CEL watertight connectors to prevent leaking into the structure to keep the water pumps dry. Now Johnstown has fresh, safe drinking water. Delaware Creek
This was a stormwater job in Toledo, Ohio. Watertight connectors were chosen over grouting to speed up the installation. The interesting thing about this job was the 42" RCP had an OD of 51.25" which is the very biggest size suggested for the #1640 A-LOK Connectors cast into these manholes. However, the extra flexibility of the A-LOK Premium connector made the installation of the pipe very quick, requiring minimum force.
A-2000 Pipe
This manhole was installed in Payne, Ohio. The picture shows a 36'' A-2000 pipe, with a smooth over sleeve, in position over the top of the pipe corrugations. It's held in place by a piece of 3/4'' plywood that fits down in the corrugation. This keeps the smooth oversleeve from moving during installation of the pipe into the #1310, A-LOK Premium Connector. The oversleeve is lubed, the pipe is centered in the connector and was pushed home. Bar Harbor
During the late 1980’s in Bar Harbor, New Jersey there was a real problem with Hydrogen-Sulfide gas when the unlined manholes they installed a few years early needed to be replaced. They tried fiberglass manholes which lasted less than 2 years. The local municipality, Long Beach Island, then installed sixteen of our Dura-Plate 100 Liners for the manholes. Below is a picture of the manhole with our liner still protecting the manholes over 20 years later.
