Please try the "Damo angular lead renovation drain," which has been reborn as a highly functional renovation lead drain.

We would like to introduce the "Damo Square Lead Renovation Drain" handled by Yamato Co., Ltd. The "Damo Square Lead Renovation Drain" is a product that has undergone a model change from the previous Damo renovation drain. It is available in two types, N (Normal) and S (With Sand), allowing for selection based on application, and it accommodates various waterproofing methods. Additionally, it has been improved to allow for easier hose insertion compared to conventional products, and the flange part has been redesigned to a rounded shape. ■ Features of the Damo Square Lead Renovation Drain N (Normal) The flange part is made of raw lead, allowing it to be used with various waterproofing methods when a metal primer is applied. ■ Features of the Damo Square Lead Renovation Drain S (With Sand) The surface of the lead flange is treated with our unique sand coating process, which allows for stable adhesion of the waterproof coating using general substrate primers, as opposed to the usual requirement of using a metal primer for lead. This eliminates the need to differentiate primers during installation around the drain, thereby improving work efficiency.

This is a vertically oriented waterproof renovation drain made in Japan. Since it is molded as a single piece without any welding, it has no seams and a smooth finish, allowing it to blend well with the substrate.

The flange section is made of lead material, allowing it to be used in various waterproofing methods by applying a metal primer. ■ Excellent substrate conformity with integrated molded products Since it is molded as a single piece without any welding, there are no seams, resulting in a smooth finish. This allows for better adhesion to the substrate during installation, preventing any steps and improving drainage. ■ Rounded corner flange section The flange section has been changed from a round shape to a square shape. This increases the area for applying the waterproof layer and makes it easier to perform terminal processing. Additionally, the four corners have a rounded shape, eliminating concerns about damaging the waterproof layer.

The "Snake Slider" processing makes it even easier to insert the hose than conventional products. The main body remains integrally molded, while the flange part has been improved to a rounded shape.

The flange part is made of lead material, allowing it to be used in various waterproofing methods by using a metal primer. ■ Excellent substrate conformity with integrated molded products Since it is molded as a single piece without any welding, there are no seams, resulting in a smooth finish. This allows for better adherence to the substrate during installation, preventing unevenness and improving drainage. ■ Easy-to-insert bellows hose Thanks to our unique bonding method, the bellows hose is securely bonded without relying on hose clamps. As a result, there are no protrusions from the hose clamps, allowing for easy insertion without worrying about the position of the hose clamps. The end of the hose is processed with a snake slider (V-cut), making it easier to insert into existing drains. ■ Rounded corner flange The flange has been changed from a round shape to a square shape. This increases the area for applying the waterproof layer and makes terminal processing easier. Additionally, the four corners have a rounded shape, eliminating concerns about damaging the waterproof layer.

The surface of the brim has been treated with a unique sand coating method, maintaining the characteristics of N (Normal). It adheres reliably to the coating for waterproofing even with general base primers.

The surface of the lead flange has been treated with our unique sand coating process, allowing for stable adhesion of the coating even with general-purpose primers, unlike the usual metal primers used for lead. This eliminates the need to differentiate between primers during installation around drains, thereby improving work efficiency. ■ Excellent substrate conformity with integrated molded products Since it is molded as a single piece without any welding, there are no seams, resulting in a smooth finish. This allows for better adherence to the substrate during installation, preventing unevenness and improving drainage. ■ Rounded flange corners The flange has been changed from a round shape to a square shape.
