I have bought foam products more than once, in particular building blocks, very quickly you can build a garage, a shed or a small box for a hydraulic accumulator and a well. There are also very good boxes for storing and transporting vegetables.
An intelligent plant for the production of expanded polystyrene "Ecoplex". Reasonable prices with excellent quality. you can buy it right on the spot, and if the volume is decent, then they will take you. The bonus was the commissioning of the polter, now you can order any figures from styrofoam.
