Abrégé

There is provided a building block assembly including a block body formed of EVA; and an adhesive layer adhered to the block body and formed of hydrophobic material having a higher viscosity. The adhesive layer comprises 20 wt %-50 wt % of rubber mixture and 50 wt %-80 wt % of high polymer resin mixed together. The rubber mixture comprises rubber, softening agent and filler. The high polymer resin uses PIB having a heavy molecular weight.
