It turns out that there’s a CEB contractor by Lathrop, Missouri – which is within 30 miles from us. Meet Floyd Hagerman, who has built a couple of very interesting CEB houses. The first one shown here is a hybrid – or a combination of CEB and standard construction. It has a Trombe wall – meaning a South-facing CEB wall, painted black, and glazed over. The wall serves as a thermal collector – and its performance is impressive. Last winter, before anyone moved in, the house remained above 40 degrees Fahrenheit all winter – Zone 5 continental climate – with no supplemental heating! Here’s a look.
Here is an example of DIY concrete blocks that Floyd pressed with his machine, by adding about 2% cement. Floyd used reject lime from the quarry, mixed in the stabilizer – and made an external retaining wall:
This was only 3 shovels of cement for over 1000 pounds of reject lime. So we are seeing the feasibility of stabilized blocks for outside use, especially if we add more stabilizer. Sealing the surface with stone sealer or similar cover would finish the job for complete stabilization from the elements.
With LifeTrac, we could throw a bag of cement in front of the soil pulverizer as we work the soil (80 lb for a 1000 lb load of soil, for 8% stabilization), and we would mix and load the soil in one step – ready to be used in The Liberator. We plan on using stabilized brick for walkways, base courses in buildings, and we are considering the possibility for building a driveway paved with brick.
Here is Floyd’s machine – a Powell and Sons version at $15k for up to 6 brick per minute pressing rates:
Here Floyd discusses the feasibility of building with CEB as a contractor – based on his experience. The big question is, does it work? How much would a CEB house end up costing? Here are some interesting insights:
On the open enterprise front, the field is rich for incubating a number of open source CEB entrepreneurs. Anybody out there considering CEB contracting?
