AS 4200

AS 4200 is an Australian construction standard that sets the requirements for below-ground waterproofing in buildings, such as basements and retaining walls. It provides guidelines to prevent water from penetrating these structures, protecting them from damage and ensuring durability. The standard covers materials, design, installation, and quality assurance measures to ensure consistent and reliable waterproofing practices across construction projects. Essentially, AS 4200 helps builders create waterproof barriers that keep buildings dry and safe from water-related issues.
