Permaform is a light weight concrete forming system in PVC, easy to assemble and cost effective. The octogonal cubes of 120 or 220 mm are interlinked, re-bars are put into the wholes and the cubes then filled up with concrete.

The insulation factor:

In addition to normal concrete Permaform is probably the best adapted formwork in the world for the use of integrated insulation or thermo concrete.
Thermo concrete is mixed with small pellets of EPS to give different effects of insulation values depending on your choice. Several buildings in different countries have been built after this method.

The vinyl stays on (if you want it to), and you have a water resistant and maintenance free solid concrete wall. You can create all types of angles - even circles - with the standard and tee elements and with the help of spacers.

Paint it!
You may paint the elements in the colour you want to!
