Waterproofing of Water Retaining Structures.
During the construction of any water retaining structures such as underground water reservoirs or concrete swimming pools, etc., it is essential to ensure the water tightness of the resulting structures so that the flow of water from inside the structure to outside, and the infiltration of water from the surrounding soil into the structure are effectively prevented.
Watertight concrete is achieved by a combination of selective materials, good workmanship and full attention to details both in design office and on site to ensure all water containing and water retaining structures should meet the strictest specifications from the conception to the design and finally the materialization of the project.
There are so many materials available for waterproofing treatment, which are more efficient for water-tightness. When it comes to the waterproofing of swimming pools, constant hydrostatic pressure combined with rigid and porous structure of concrete pose serious challenges for an effective and lasting job.
Indian standards are not up to date with latest technology and material for waterproofing of swimming pools & reservoirs. A water retaining structure may be defined as a hydraulic structure designed to hold back, restrain, or obstruct the flow of water. The treatment of a surface or structure to prevent passage of water under hydrostatic pressure is known as waterproofing of such water retaining structures. The different water retaining structures may be of following types: • Swimming Pools • Reservoirs / Water Treatment Structures • Underground Water Tanks • Overhead Water Tanks • Ponds, Water Features and Fountains • Sewage Treatment Structures
Design Consideration & Precautions Suitable precautions should be taken to avoid cracks and leakages in water retaining structures resulting from the following:
• Movements due to shrinkage and creep
• Movements due to variation of temperature and humidity
• Movements due to dissipation of heat generated by the concrete in the process of hydration
• Damage to the concrete by the percolation of chemically aggressive liquids from outside.
Damage due to uneven settlement of foundations
• Cracking of concrete caused by rusting of bars
• Hydrostatic uplift force to avoid temperature changes as far as possible, the water tank should be built partly into the ground so that the soil is available to cover the roof, if necessary, and to form embankments on the outside so as to enclose the water tank completely in a covering of earth.
