Monolithic’s Airform technology can be used to build culverts.
What’s more, this technology produces quality products for less money.
It is far less expensive to build a culvert by using an Airform than to build one any other way. This is especially true in the developing world. Here in the United States, we can contact a company that makes steel or concrete culverts, and, chances are, the desired product can be delivered in a matter of hours. Not true in other parts of the world – and even here it’s not always possible, especially if you need a custom culvert.
But by using an Airform, custom culverts, particularly very large ones, can be constructed easily and economically.
Here’s the process:
It’s fast, simple, extremely secure and can be done anywhere. The concrete doesn’t even have to be shot in place; it can be spread by hand.
In many parts of the world, a three-foot-diameter culvert is all that is needed to make a back-country road serviceable. These culverts are not only easy to build, but can be constructed in multiples. If a stream is large enough, three-foot-diameter culverts can be built in multiples of five or ten to let the stream move through.
The tough, spray-in-place culvert
No doubt some people will fuss about spray-in-place culverts. The fussers will probably say, “We can’t be positive that they won’t leak.” Believe me, the others do leak! They have factory joints that leak!
But the spray-in-place culvert is a reinforced single unit, that is far tougher than a culvert made of fitted-together pieces.
Repairing existing culverts
Existing culverts can be shotcreted if they have diameters large enough for a crew to work in. Such shotcreting is not often done simply because most engineers don’t know about it. Nevertheless, shotcreting is an extremely viable alternative for repairing large culverts. Workers can go inside and attach new reinforcing and spray it in. This is far simpler than tearing up streets or roadways to put in a new culvert and, usually, it costs less. Using this technology, large drain pipes, including sewers, also can often be repaired.
