Lime-Hemp Groningen promising for earthquake resistant building

Groningen, The Netherlands – EcoBouwSalland, HempFlax and Sanger IBCT are studying how home insulation based on a mixture of hemp and lime hemp behaves during earthquakes. This research is supported by the NAM (Dutch Petroleum Company). Earlier tests had shown that the product has a low modulus of elasticity. This means that it gives way, instead of tearing.

The flexibility of lime is well known in the construction industry.
