on building with hemp bricks

Dr. Norbert Hoepfer

 

The workshop shows a new way to produce and use building materials (hemp lime).

This requires a chain:
1. agriculture and harvesting technology
2. hemp processing / separation of raw materials into shives and fibres
3. hemp stone manufacture / production of hemp-lime insulating stones
4. processing of the stones

Point 1 to 3 are produced and worked out in the hemp lime manufactory Zempow, this is a German exception, normally the hemp straw is brought from the field to the processing plant, this can be several hundred to 1000km, we drive here only a few 100m to 2 km.

This workshop offers the technology and guidance to get this new building material.

Rethinking the production of building materials
Hemp hurd bound with lime shows the new way!
(hemp lime is a mixture of the binder lime 1 part & 3-4 parts supplement of hemp hurd, the broken pistil of the plant)

Tiny house can be dismantled for reuse, size about 2,2 x 4m with an indoor wooden framework. Facade out of hemplime bricks as drywall, shed roof with hemp wool insulation.

Hemp lime has the following properties

  • regional & mobile manufacturing
  • can be implemented directly with little effort
  • carbon negativ (pro cbm minus 110-130 kg CO2)
  • Hemp from natural fields (free of glyphosate)
  • built-in moisture protection via the buffering effect of the binding agent
  • suitable for grandchildren
  • sand free
  • cementless
  • vegan
  • transparent supply chain of raw materials

We use hemp hurd because:

  • hemp is grown in Brandenburg & Mecklenburg
  • in our case, the hemp comes from regional organic farming in Zempow
  • these occur en masse in the hemp plant
  • hemp has an open-pored cell structure
  • hemp has a positive effect on agriculture field economy

We take lime because:

  • a lot of moisture is buffered (rapid absorption and release of moisture)
  • because of the disinfecting effect
  • easy to repair (our bones are made of lime and therefore grow back together)
  • lime is thinking ahead evolutionary
