Example of an upstairs hemp and lime pavement

In this case, the wooden framework was in place, and we decided to fill all empty spaces with hemp and lime to obtain a massive but light efficient acoustic insulation.

      

ADVICE : You don’t need to put some pre-framework before the pouring. Set up the pouding directly on the floor until reaching a flat base.
Put the joists on the dry pavement and fix the wooden framework (or make a lime with sand pouring and implement a coating like terranova …)
