Finally, we put our plan into action - we poured WU (waterproof) concrete into the polystyrene formwork blocks, filling the space between the blocks and our uneven foundation. It was challenging, and filling the space behind the polystyrene blocks was a bit risky, as we didn't know how much lateral pressure the blocks would withstand. There was a close call, but in the end, everything worked out as planned, and thanks to the newly concreted plinth, the bottom 50cm of our foundation is now supported, insulated, and fairly waterproof.
