ᐅ Pouring concrete without ready-mix concrete / mixer truck – alternatives?

Hello,

I have a question about possible alternatives to ready-mix concrete.

Is it possible to mix concrete on-site for the basement and ceiling slabs?

My problem is that our property is accessible only by a very narrow road on one side and on the other side there is a bridge with a maximum load capacity of 9 tons.

I have contacted several concrete suppliers in the area, but they all only have large trucks for delivering concrete.

The concrete is needed for a 150 sqm (1,615 sq ft) basement, a basement ceiling, and

Thank you in advance for any help and tips.

Of course, concrete can also be mixed manually using a mixer or a screed concrete machine. But who is supposed to do that? Discuss this with your construction company. It is possible.

A 150m² (1,615 sq ft) basement is already a significant size. Just in case mixing by hand becomes too expensive at German market prices, I would consider getting an alternative quote from a crane company. They have so-called "bridge launching systems" designed for "structures with limited load capacity, such as bridges or viaducts with either weak or deteriorated components." If you want, I can send you the contact of a provider we have had very good experiences with via private message when the time comes.

Why not use pumps? They can easily handle 30 meters (98 feet) high and 50 meters (164 feet) horizontally with any vehicle.

Let it pump. Adding admixtures at this size is a really tough job.

Hello and thank you for the many responses,
The pumping idea sounds very interesting. Is it possible to pump more than 50 m (165 feet)? In that case, it would probably be necessary to set up a station by the road.
We have a distance of 30 m (100 feet) and an elevation difference of about 5 m (16 feet) to the road.
It will then only be important to find out if closing the road is allowed.

Our client will have to clarify that now. I’m curious to hear what he thinks about the pumping solution...
