Understanding Waterproofing for Construction
Waterproofing is essential for preventing water leakage in structures like bathrooms, toilets, and terraces. It helps maintain a habitable environment, protect building components, and increase the building's lifespan. Causes of leaks include structural movement and temperature variations. Different waterproofing systems and methods for slabs and sanitary blocks are used, utilizing materials like emulsions, mastics, and sheets. Proper waterproofing ensures the durability and safety of buildings.

Waterproofing: This is the method of giving the treatment to a surface or This is the method of giving the treatment to a surface or structure so as to avoid the passage of water under hydrostatic structure so as to avoid the passage of water under hydrostatic pressure is called water proofing pressure is called water proofing resistance of construction to the leakage of water is known as waterproofing. Where it is done Where it is done? Bathroom Bathroom Toilets Toilets Terraces. Terraces. Usually membrane waterproofing is used which is of one or two Usually membrane waterproofing is used which is of one or two layers layers.

NECESSITY: IN BUILDING ALL THE BUILDING COMPONENTS SHOULD REMAIN DRY AS FAR ASS POSSIBLE. IF THIS CONDITION IS NOT SATISFIED THEN THE BUILDING BECOMES INHABITABLE & UNSAFE FROM STRUCTURAL POINT OF VIEW.IN ORDER TO PREVENT THE ENTRY OF WATER OR TO EXIT WATER FROM THE BUILDING WATERPROOFING IS NECESSARY. -TO PREVENT LEAKAGE.

Causes: Movement because of structural deflection & steep Movement because of structural deflection & steep temperature variations are the main reasons for temperature variations are the main reasons for cracks which leads to the leakage cracks which leads to the leakage. Types of waterproofing systems: Hydrophilic- water in the concrete is replaced by in soluble crystals Hydrophobic: Fatty acids which blocks the pores within concretes..
Water proofing for slab: Following methods are used . 1.finishing- cm 1:4 is used. 2.bedding concrete & flooring. brickbat lime concrete 1:2:4 -----------------cc 1:2:4,1:5:10,1:6:12 Th=100 mm over which tile are laid. 3.Mastic asphalt & jute cloth 4.Use of water proofing compounds.
Water proofing of sanitary block: Bathroom Toilet Sink Basin Nahani trap =200 mm Indian wc =500 mm Water tightness of structures,pipes is important. 1:3 motor is used in waterproofing compounds are added.
Materials: Emulsions & pastes Mastics hot & cold Roll & sheets-cardboards with sp.bituminous tar compounds. Sealing materials. For more detail contact us For more detail contact us
