Notice of Name Change for Damocorn Type Lead Renovation Drain Size

山装 山装 防水資材事業部
We have decided to change the size names of the dam corner type lead renovation drains as follows. Due to numerous requests from customers to align the naming with the drainage pipe of nominal diameter 75, we will be adding a parenthetical notation to the existing size names to accommodate this. While the size names will change, we kindly ask that you do not judge based solely on the size names as before, but instead confirm the dimensions of the site and the drain before selecting the size. 1. Regarding the timing of the change The change will take place around August 2021, as soon as the old stock is depleted. 2. Regarding the content of the change Before change After change Outer diameter (cylinder part/hose) For N vertical type 80 For N vertical type 80 (for 75) φ75mm For S vertical type 80 For S vertical type 80 (for 75) φ75mm For N horizontal type 80 For N horizontal type 80 (for 75) φ72.6mm For S horizontal type 80 For S horizontal type 80 (for 75) φ72.6mm

Damo square-shaped lead renovation drain N (Normal)/S (With sand) Vertical type Horizontal type

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.

Damo square-shaped lead renovation drain N (normal) vertical type

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.

Dammo square-shaped lead renovation drain S (with sand) vertical type

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. This increases the area for applying the waterproof layer and makes it easier to handle terminal processing. Additionally, the four corners have a rounded shape, eliminating concerns about damaging the waterproof layer.

Damo square-shaped lead renovation drain N (normal) horizontal type

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.

On August 28, 2026 (Friday), I participated in the "AMD Embedded Computing Summit Tokyo 2026" and showcased a "Gesture Demo" as a partner of AMD. The demonstration introduced a configuration that combines gesture recognition using OpenCV, status reporting with LLM, and one-axis motor control using INtime 7.2 and RSI-ECAT, enabling collaboration between AI, image processing, and real-time control on a single PC. We presented a next-generation PC-based industrial control system that integrates AI, image processing, and real-time control on one PC. <Overview of Demo Participation> https://www.mnc.co.jp/INtime/AMDxINtime/AMDEcsTokyoResults.html <Actual Demo Video> https://youtu.be/JmZke75_y0s <AMD CPU + INtime RTOS Introduction Page> https://www.mnc.co.jp/INtime/AMDxINtime/amdxintime.html #PC #RealTimeOS #IndustrialPC #AI

We have published an article comparing and ranking six system construction manufacturers for 2026 on the Select Beam special site.

  • NEW
  • COMPANY

We have updated the article on the website of the semi-custom system construction "Select Beam." When planning factories, logistics warehouses, and stores, "system construction" has become an effective means of achieving cost reduction and shortening construction periods. The rationality of system construction through thorough standardization is very high, and it is adopted in many projects. However, due to the differing characteristics of each manufacturer, many business owners find themselves wondering, "Which manufacturer is suitable for our plans?" and "Is it really optimal compared to conventional methods?" In this article, we will compare and introduce the basic knowledge of the advantages and disadvantages of system construction, as well as recommend manufacturers by purpose in a ranking format. ■ Semi-Custom System Construction "Select Beam" This is a unique method by Sakura Structure, and it is a "third option" that is less expensive than system construction. It is the most suitable method for low-rise long-span buildings such as stores, warehouses, factories, and logistics facilities, as well as high-rise buildings like hotels.
