EVA self-adhesive waterproof roll adopts synthetic high polymer EVA processing composite sheet, high polymer and modified high-quality asphalt as the base material. The composite new synthetic high polymer waterproof roll with excellent waterproof performance has the waterproof performance of high polymer waterproof roll and self-adhesive waterproof roll. One layer of roll, two layers of fortification, greatly improves the waterproof effect of the waterproof layer. EVA self-adhesive waterproof roll can be divided into non tire base (n type) and polyester tire base (py type).
