What is Integral waterproofing (concrete waterproofing)? Explain in details with application procedure and typical use.
Integral waterproofing, also known as concrete waterproofing, involves adding waterproofing agents or admixtures to the concrete mix during the manufacturing process. The waterproofing agents diffuse into the concrete and become a permanent part of the structure, providing a continuous barrier against water intrusion.
The application procedure for integral waterproofing typically involves the following steps:
- Design and specification: The design and specifications for the concrete mix must include the appropriate waterproofing admixtures, taking into account the specific requirements of the project.
- Batching and mixing: The waterproofing admixtures are added to the concrete mix at the time of batching and mixing. The amount and type of admixture used will depend on the specific requirements of the project and the conditions.
- Placement and curing: The concrete is placed and cured in the usual manner, with the waterproofing admixtures becoming a permanent part of the structure.
Typical uses of integral waterproofing include:
- Foundation waterproofing: Integral waterproofing is commonly used to waterproof basement walls and foundations, providing a continuous barrier against water intrusion.
- Underground structures: Integral waterproofing can be used to waterproof underground structures such as parking garages, tunnels, and retaining walls.
- Water containment structures: Integral waterproofing can be used to waterproof structures such as dams, water tanks, and reservoirs.
Integral waterproofing offers a number of benefits, including durability, ease of application, and the ability to create a continuous, watertight barrier. However, it is important to choose the appropriate waterproofing admixture for the specific requirements of the project, and to follow the manufacturer’s instructions carefully.
