Your project sometimes needs more than just a custom size; you may require a custom shape. The walls have to match existing conduit layouts and elevations. Racking hardware must be installed on 45 degree angles. You just know a square or rectangular concrete structure won't be the perfect fit. Are you counting 5 sides? 6 sides? How about 8 sides? There's no need to be stressed. Contact Advance! We have state-of-the-art systems in place to get your mission accomplished, from concept to reality. Advance Concrete Products has the team to get your octagonal precast concrete manhole designed, manufactured, delivered and installed, so you can move on to your next project. Our experienced production and installation crews will make sure all concrete components fit together perfectly. We will make you look good, no matter what shape.

3-Pc Manhole
Panel Power Manhole
 
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 10' x 10' or 13’ x 9’ rectangular vaults that can be made 30’ 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.
