Sai Kung District is located in the southeastern part of the New Territories, covering Sai Kung Town, Clear Water Bay, Tseung Kwan O, and Hang Hau, with a diverse range of residential types spanning estates and buildings from different eras. Estates from the 1980s-90s such as 翠林邨 (Tsui Lam Estate), 寶林邨 (Po Lam Estate), and 新都城 (Metro City) are progressively entering their renovation cycle. When homeowners carry out rooftop renovation, facade repair, or bathroom waterproofing projects, they often require professional-grade waterproofing and repair materials, with growing demand for waterproofing and plastering maintenance. Coastal properties in Sai Kung are continuously exposed to sea breeze and salt spray, making high-specification salt-spray-resistant waterproofing coatings a preferred choice when homeowners carry out facade maintenance. In recent years, Sai Kung District has also seen new projects adopting Modular Integrated Construction (MiC), such as the Pak Shing Kok Disciplined Services Quarters in Tseung Kwan O. Waterproof sealing at module joints is critical for long-term leak prevention, requiring high-performance expansion joint sealants and sealing compounds. Wahhing Construction Waterproofing Materials supplies Sai Kung District homeowners and contractors with a full range of waterproofing and repair materials from international brands including Sika, Fosroc, Mapei, Weber, and Optimix.
