To view some of our standard size precast concrete structures, see the sample drawings on the bottom of this page to download a pdf version. Options can be changed to match your specific requirements. Roof openings, wall openings, access covers, conduit terminator sizes and locations can be changed; the pdf's are merely examples. If you don't see the size your job requires, we can manufacture a manhole which will fit your project. Have existing lines? We can provide doghouse openings and panelized manholes to install around your steam pipe, conduit and ductbanks. Please contact Advance Concrete Products for a custom drawing.

We manufacture a variety of standard size manholes and handholes. What is considered a handhole? Simply a structure not tall enough on the inside to stand upright. A manhole is one with 6' of headroom or more, so a person can service conduit or equipment inside, while standing.
Our precast concrete standard structures are quite versatile. By adding midsections, the “two-piece” can become taller. They range in size from 2’ x 2’ square, all the way up to 14' x 7'-6" or 13’ x 9’ rectangular vaults that can be made 20’ or taller. We have varying wall, floor, and roof thicknesses to satisfy your loading requirements, ranging from pedestrian to aircraft.
If you have an approximate idea of what size precast concrete manhole or handhole you are looking for, we can quote your exact size and also offer the closest standard size at a savings, so you have choices. Please see the pdf versions of some of our standards sizes on this webpage to download for your project.
Our handholes and manholes are used for traffic signal projects (ITS), underground communication and telephone ductbank systems, electrical substations, new lighting installations, and airport power/telecommunications.

Time was a very critical factor and they made the manhole delivery happen.
No other concrete company was able to provide what we needed in the short time frame we had. Fortunately, Advance Concrete Products had the product we needed ‘on the shelf' ready to go. Time was a very critical factor and they made it happen.
Advance Concrete Products does an exceptional job for us. We tell them what we need and when we need it and they're sitting there waiting for us. They even sped up my delivery by two days to help me out. The bottom line is they do what they say they're going to do. Today that's unique. It's refreshing to work with Advance.

Advance makes it happen
When I work with Advance Concrete, my job is easy. I call with a request and they usually come out that day or the next to take measurements on the structure we need. Two or three days later the structure is ready to go in the ground. Time is money for us and we can't wait a week and a half for a manhole. We need it A.S.A.P. and Advance makes it happen.
