Expansion Joints

Watch Out these "Joints":

Construction joints, which happen when new concrete is poured against existing concrete

Expansion joints, which allow for movement between adjoining building parts due to thermal expansion

Control joints, which help to control cracking due to temperature changes and shrinkage from drying

What is Cost of Waterproofing? Simple Analysis

Keeping in view general principle of Waterproofing and Water Damage Restoration Services Cost/Benefit analysis, negotiating or cutting construction cost is seldom if ever justified for ever a slight increase in leakage risk. 

The high cost of remedial Waterproofing work should deter any owner and his designer / architect from endorsing any risk increasing first cost economies.

Terrace Maintenance and waterproofing

Terrace Maintenance 

The Terrace of the building is the first thing that comes in contact with rainwater. For Gated communities and societies in particular, Terrace is not used very often so chances of neglect in cleaning are more.

This may result in water accumulation and ultimately seepage. Also with the passage of time the concrete in slabs starts to expand and contract with temperature variations. This can cause cracks on the surfaces allowing water/moisture to seep in if the terrace is not waterproofed properly.

To prevent such issues it is ideal to do a thorough waterproofing of the whole terrace surface.

The conventional ways of waterproofing are the brick bat coba, but even this system being very rigid falls short against temperature variations and cracks up. The worse thing is that the presence of brick causes additional absorption of water through the cracks and finally seepage.

The expert solution for arresting such roof cracks would be to contact professional waterproofing service provider for waterproofing audit and devising system that is sustainable for years as a waterproofing coating.

Liquid terrace waterproofing

Liquid Waterproofing Membrane 

Liquid waterproofing membrane is available in the form of liquid and is sprayed or applied by brush or roller to the concrete surface which forms a thick joint free membrane in contact with air.

Benefits of Liquid Waterproofing Membrane over other conventional methods

The benefit of this process lies in its simplicity to apply. The joint free process is the most important benefit as there are significantly no chances of seepage of water unlike in roll sheet WPM and other water proofing methods. The contractor can cover larger area in a day and if applied next day can start overlapping the layer finished last day with spray liquid waterproofing membrane.

Precautions:

The membrane thus formed should be proper thickness as thinner membrane can break down, care has to be taken by installer and engineer in charge.

Features of Liquid Applied Waterproofing Membrane

These liquid applied systems feature coatings have elongation properties, durability, flexibility, abrasion, chemical resistance providing successful installation. The liquid waterproofing membrane provides optimized performance and also most importantly longevity.

While sheets and other membranes degrade over time, liquid applied waterproofing provides long lasting effects. When applied over concrete surface it fills the cracks of the concrete creating a protective vapor barrier system, penetrates in concrete up to a depth of 20 mm and maintains a water tight seal, thus increasing the strength of concrete. Applications of Liquid Waterproofing Membrane

The liquid waterproofing membrane can also be applied on metal deck steel bridges which have space age joint system. It prevents the seepage from the joints. It increases the longevity of the bridge and this comes into picture when the bridge is rebuilt after 10-15 years.

Liquid waterproofing membrane not only prevents the cracks but also prevents the corrosion of inner materials, the steel bars, and the joints. It seals the cracks up to 1.3 mm width and can withstand expansion up to 0.4 mm and what more the bridge is ready to use for traffic in less than 6 hours.

It gives a low maintenance service long life.

Types of waterproofing

There are some common types of waterproofing methods used in construction industry. Waterproofing in buildings / structures are generally required for, Basement of structure, Walls Bathrooms and kitchen Balconies, decks Terrace or roofs Green roofs Water tanks Swimming pools
The following waterproofing methods are commonly used in construction:

1. Cementitious Waterproofing
2. Liquid Waterproofing Membrane
3. Bituminous Membrane
4. Bituminous Coating
5. Polyurethane Liquid Membrane

Efflorescence

             Efflorescence




Have you seen white, powdery and dusty-looking deposits on your walls, especially around the corner edges of your home? Well, it’s time you acted on it! Why? Because, not all white things are pretty, what we are staring at is: Wall Efflorescence: a condition where salt (white) deposits are formed on the surface of the Walls.  The formation of salts is usually a result of excessive moisture in the tile. It is also known as Whiskers.

What is the cause of wall efflorescence?
The appearance of this white-coloured grouts or salt deposit happens when water enters the brickwork. The internally held salts dissolve in the water, while leaving its essential salts into masonry. So, what is left on the wall is the surplus from the base of the concrete. Basically, as the water evaporates from within the surface, the natural mineral in the water crystallises and becomes visible on the surface. Thus, if the walls are darker then efflorescence becomes more apparent.

What are the stages of wall efflorescence?
Efflorescence is a common occurrence, and it happens largely on more porous stones and sometimes even on tiles that aren’t on non-porous surfaces. The most common places, where you will notice efflorescence is around bathroom, driveway, and other areas that are likely to have high moisture. This happens in two stages:
One that happens instantly after usage is known as primarily efflorescence, and the other that happens at a later time – secondary efflorescence.

Impact of Efflorescence 
The good news is that this annoying built-up isn’t hazardous. This is just salt and can be easily removed. However, it is also an indication of excess moisture. So, it’s important to treat the moisture issue, which can cause deterioration if not treated in time. But, on the whole, efflorescence on the surface is mostly an aesthetic issue.

Treatment for Efflorescence
Sandblasting is one of the most popular and traditional ways of cleaning tile efflorescence. However, it’s harsh on the overall surface and removes everything in sight. Basically, the abrasive action of sand erodes the surface of the brick and the mortar joints along with salt deposits. This, in turn, makes the surface highly porous. Thus, it’s key to use sandblasting with caution, and follow it up with waterproofing.

The other option is to go with special chemical cleaners. Here, one must follow it up with a thorough cleaning of the surface with water to ensure that the floor is free of all cleaning agents, which could be acidic in nature.


The best course of treatment is ensured by blocking capillaries of porous building material and providing durable coating on the surface. Call 9711580095 / 836869715 Decor & Design
