Notice of participation in 'JECA FAIR 2026 - The 74th Electrical Installation Industry Exhibition' from May 27 (Wednesday) to May 29 (Friday), 2026.

[Official Release] Waterproof Sleeve for Underground Walls "Pipe-in-Sleeve" (Abbreviated as PIS) Reducing Labor at Construction Sites! Enhancing Waterproof Performance of Buildings!

■Recently, our "Pipe-in-Sleeve," showcased at the JECA Fair 2025, is officially launched with great anticipation.■ In the underground wall section (underground beam sleeve), we have pre-treated the PVC sleeve and the outer space (gap) of the FEP with "waterproof treatment" at the factory, making it prefabricated for the site. No cumbersome work is required on-site; after the PIS installation, only joint connections are basically needed. Ensuring stable waterproofing! Achieving work efficiency and promoting flood prevention and water resistance. This is an innovative and advanced product for underground beam sleeve construction. <Features> ■ Excellent waterproof performance [Flood prevention and water resistance promotion] ■ Proposal for labor-saving at construction sites ■ Adaptable to individual design specifications of construction projects ■ Improved work efficiency, standardized quality, and enhanced maintenance [To designers and contractors] FEP pipe routing, bell mouth terminal installation, connection of different types of pipes (AQ type), and various connection parts of FEP can be arranged to fit the specifications of individual construction sites! Furthermore, it can also respond to unexpected leaks! It combines maintenance and serviceability, making it a versatile and highly adaptable product.

Reduction of work on the outer wall of the underground beam (underground beam sleeve) and enhancement of waterproofing performance.

With the increase in building height and seismic resistance improvements, the width of beams has been increasing. - Increased amount of rebar (main bars and stirrups) in beams - Spread of high-strength concrete - Long-period and wind sway countermeasures - Increased load on beams due to the slimming of columns (design requirements) - Improved workability (especially with high-strength concrete) As a result of these factors, recent high-rise buildings show an increase in "beam width," particularly for underground beams, which tend to be significantly thicker, with widths exceeding 1,000 mm not being uncommon. Therefore, waterproofing work for the outer circumference of cable conduits penetrating through sleeves in underground exterior wall sections (underground beams) is extremely challenging. Due to the current shortage of construction workers and skilled labor, the waterproof performance of buildings is becoming increasingly unstable. Thus, we propose the following: **Application Scenarios** - Piping work for underground beams - Sleeve penetration work for exterior walls - Pulling through FEP pipes **Benefits of Implementation** - Significant reduction in construction time - Reduced burden on workers - Stabilization of quality - Decreased risk of water leakage

~ A high-efficiency customer attraction strategy where homebuyers come in saying "I saw it on ○○!" and a product/design strategy that is specifically requested as "I want to build with Harbor!" ~ In an era where simply creating a "good house" is not enough to survive, rising material costs, labor shortages, and intensifying competition with major companies have made the environment surrounding local construction companies more challenging than ever. Amidst this, Harbor House, which has been established for 19 years in the fiercely competitive Niigata Prefecture, has achieved an annual completion of 450 houses and is now the number one in the number of starts in Niigata Prefecture. Its strength lies not in a single charismatic leader, but in a thoroughly refined "system." Customers who say, "I came after seeing your website" are reliably guided to contracts through a high-efficiency sales flow based on "batting average management." In this online seminar, we will generously share the know-how of customer attraction, product, and management that Harbor House practices with business owners. We will present the shortest route to becoming a "construction company that continues to be chosen" in your business area. ◇ Detailed information and application https://x.gd/pUe2b ◇ Phone inquiries TEL: 025-383-8881
