Waterproofing techniques are methods used to prevent water from penetrating structures, ensuring durability and safety. Common techniques include the application of waterproof membranes, which are sheets or liquid coatings that create a barrier against moisture. Other methods involve the use of sealants and waterproofing paints that can be applied to surfaces like walls and roofs. Another effective technique is the installation of drainage systems that redirect water away from buildings. This can include French drains or gutters that help manage water flow. Additionally, foundation waterproofing involves treating the base of a structure to prevent water ingress, protecting it from potential damage.
