Like you guys can see on the photograph we started with a primer on the walls that will be covered by soil after we filled holes and inperfections on the surface.
The product that we use to seal the walls is a 4mm torch on system that is applied by torch fusion( PG gas with a flame gun attached ) the Lapjoints has been heat-sealed with a100mm overlap.
The reason why we seal the walls(that is covered by soil) that way is to stop the moisture from penatrating the walls.
and causing dampness in the inside walls.
Thank you for reading my post and i will give an update when its on the next stage of the project
Remember always to smile :)
