Types of Concrete Waterproofing

You can waterproof the positive (exterior) side, the negative (interior) side, or from inside the concrete itself to make concrete truly waterproof, which means both preventing water passage and resisting hydrostatic pressure (integral systems). While sheet membrane waterproofing is the most commonly used positive-side technology, its failures and limitations are also widespread and expensive. As one of the professional waterproofing contractors in Bangalore, many building schemes across the globe have used integral crystalline admixtures to waterproof concrete since the 1980s. By operating from the inside out, critical systems block water passage from either direction, rendering the concrete the water barrier itself.

Concrete Waterproofing uses an impermeable material coating on concrete that prevents water from entering and waterproofing the structure such that water remains relatively unaffected. Concrete is a pervasive and porous compound that absorbs water, pollutants from water, and chemicals that cause concrete to deteriorate.

Advances in both membranes and crystalline admixtures can be challenging to keep up with, and there have been significant advances in both technologies. Here’s a description which will help to make the option easier..

1.Cementitious Waterproofing:

Cementitious Waterproofing in construction work is the simplest form of Waterproofing. However, as used in internal wet areas such as toilets and kitchens, it is not exposed to sunlight and weathering. The materials used for the Waterproofing of concrete are readily available. Therefore, in the cement waterproofing market, the process of expansion and contraction will not take place. This technique is used in areas such as toilets and bathrooms that are wet.

2. Liquid Waterproofing Membrane:

A liquid membrane is a thin layer typically composed of a primer coat and two coats of waterproof liquid membrane spray or roller. It provides more flexibility by creating a rubbery coating on the applied surface than the waterproofing cement method. Waterproofing’s performance depends on the form of polymer used in the phase of liquid Waterproofing. The liquid membrane is composed of polymer asphalt that has been modified. For Waterproofing, polyurethane liquid membranes are also used. 

3. Bituminous Coating:

The bituminous coating, also known as asphalt coating, is flexible and protective. It is a perfect protective coating agent and waterproofing agent, especially on concrete foundation surfaces. The bituminous coating consists of a bitumen-based material and is not suitable for sunlight exposure. Owing to prolonged exposure to sunlight, it becomes very brittle and delicate.

A standard method used for low sloped roofs is bituminous membrane waterproofing. There is a torch on the membrane for the bituminous membrane and a self-adhesive membrane. Asphalt, polymers, and filler contain self-adhesive compounds. The self-adhesive form has a short shelf life, as the membrane’s bonding properties decrease with time. It is a mixed material consisting of too sticky, viscous, and waterproof organic liquids. 

The torch-on membrane uses a fire contact to melt the bituminous layer on the member for bonding.

4. Admixtures:

A modern method of Waterproofing has been used around the world over the past few years. At the batching plant or on the ground, these admixtures are applied, and they will react chemically within the concrete that transforms the concrete into a water barrier itself. Densifiers, water repellents, or crystalline admixtures may be comprehensive concrete waterproofing devices.

5. Crystalline Admixtures:

Usually, crystalline based systems come in a dry powder shape. In reality, crystalline structures use available water to grow crystals within the concrete, effectively closing the moisture channels that can damage the water barrier itself.

In applications under continuous motion, integral crystalline waterproofing systems should not be used. Crystals align in a three-dimensional array during the crystallization process, which fractures when exposed to extreme movement. Another way of Waterproofing will be safer for areas that need versatility and face routine activity, such as plaza decks or rooftops. For more information visit waterproofing Delhi.
