Different Joints of Building & Sealing of Pipe penetration point

We have found many water leakages from joints of RCC structures.There are mainly four types of joints in RCC/Concrete structures. 1. Construction Joint 2. Connection Joint 3. Movement Joint (Expansion Joint) 4. Control Joint/Dummy or Contraction joints

CONSTRUCTION JOINTS are designed to split areas of the structure into separate concrete section for work schedule reasons or as structural measures to transfer load. The reinforcement in construction joints is therefore continuous through the joint.

CONNECTION JOINTS Connection joints are flat or indented joints which split the concrete section trough its full depth without a defined joint gap. The reinforcement in connection joints is discontinuous. Joint opening & pressure transmission is possible.

MOVEMENT JOINT (EXPANSION JOINT) Movement or expansion joints split components trough their full thickness with a designed/defined joint gap. The reinforcement in movement joints is discontinuous. Movement joint allow differential movement due to temperature variations and /or load or settlement in one or more direction of the areas, section or structures separated by joints.

CONTROL JOINT (CONTROLLED CRACK INDUCED, DUMMY OR CONTRCATION JOINTS) It is intentionally provided or created joints with specific interval of defined depth & width to create weak zone of concrete to relieve the stress due to temperature & stresses. Which thereby prevents uncontrolled cracking of structure.74People reached2Engagements–Distribution scoreBoost UnavailableLikeCommentShare

Floor Tile Issues & Fixes Recommended by Waterproofing Contractor in Kolkata

Whether it is a damp on ceiling, water leakage in bathroom or saltpeter infection in your exterior wall, repairing in the ‘right process’ and ‘on time’ is highly important, says a waterproofing contractor in Kolkata.

Mostly people ignore such issues until it starts spoiling their daily life. But, it’s not only about your day-to-day life — it’s directly related to your biggest asset and safety of your family.

Well, there are serious people who spend enough money repairing their building issues. But, mostly they don’t have enough knowledge on how to save money on repairing or how it can be long lasting. As a result, they end up wasting their hard earned money and making the issue complexer.

So, what’s the solution? Here are some tips from our senior waterproofing contractor in Kolkata, Mr.Kaushik Sarker.

Broken Floor Tile

Tiles are weaker compared to marble stone and thus falling of some item on the floor or heavy weight may break the tile. Mostly it affects the adjuscent tiles also with hairline fracture which is mostly invisible on human eye, but is enough to seep water down the foundation.

In such cases, replacing the damaged tile or trying the seal the gaps using any sealant will just make your floor look ugly and let germs grow. It will also cause damping issue in the long run and will detach other tiles from the adhesive used underneath.

So, it’s always suggested to go for hiring professional and let them cut out the damaged tiles and install new ones perfectly. Make sure to choose right quality of adhesive and paste the tiles finely matching with the other tiles.

Darkened Grout

Grout is the mortar used in between tiles to seal the gap. It is a category of cement which acquires dirt and gets darkened over time. It is unhygienic and also spoils the beauty of the floor.

How to get back the original colour? First of all, you can try cleaning the grout using some herbal acid and a fibre brush. Rub the grout repeatedly and wash off using cold water. If it is a too old installation, might be this system doesn’t work. So, on that case, you have to peal off the mortar and have to re-apply it in the gaps.

Chips on Tiles

Probably a heavy item dropped on your tile and it got chipped. Though it’s not vulnerable for the health of your home, it can look ugle and mostly in case of colourful tiles, it will attract visitor’s attention.

What to do? Well, you can take out your makeup box and use any high quality nailpolish of similar colour. It’ll give you the almost same gloss and colour mostly and will recover the issue. However, it’s not a long term solution and you might have to repaint it in every fortnight (in case of high traffic areas) or litlle longer.


As per one of our waterproofing contractors in Kolkata, it’s always best to go for good quality marble stones instead of tiles, if you have little higher budget. It’s long lasting, cool and elegant. However, the negative side of stone is maintenance. If you have further query on that, read our other blogs.

Better Home Space Management — Tips by Waterproofing Contractor in Kolkata

Any builder will tell you about carpet area when you are interested to purchase a new building; and that’s the parameter that buyers also pay most attention to when buying a house, says a waterproofing contractor in Kolkata.

But, does that tell you perfectly about how much space you are going to get? Mathematically, there is no conflict. But, come to real experience, you’ll find that almost 30% or even more of the carpet area on an average remains unusable just because of a wrong design.

What is called ‘unusable area’?

The name itself says the definition. However, you have to go deeper to understand the actual meaning. When a builder designs a home, he thinks about a particular type of homeowner and creates the design accordingly. But, not necessarily it will fit with your particular requirements.

Say your builder created a wide balcony to spend time looking at your garden. But, if both you and your spouse are a businessperson, probably you won’t be able to enjoy this ‘luxury’, isn’t it? Similarly, a place in your entrance designed to park your bycicle may remain unusable just because you own a car and not a bycicle. But, you paid for that space as well, right?

What’s the solution?

If you are developing a new building for your own, you are in a safe position to rectify the issue, says our waterproofing contractor in Kolkata, Mr.Kaushik Sarker. You can consider the following factors while creating your floor plan:

  • Number of members in your home
  • Furniture and fixture you are going to install
  • Your luxury preference (more spacious means more luxurious)
  • Your decoration planning (indoor garden, wall-paint, flower vase etc.)
  • Your total carpet area

Have you already purchased a ready building? Then probably you cannot apply these methods directly. As per our waterproofing contractor in Kolkata, it’s best for you to go for other techniques to ensure right space management.

Here are few of them that you can consider:

Plan Alternate Use of Space

Maybe some space in your home were designed for a specific purpose that you no longer need. So, is it possible to use the space for any other purpose? Think on the matter and you can find some great idea out of the blue.

Plan for Modifying Your Furniture

Often changing the shape and size of furniture creates new space and makes some space more usable. So, consult with some experienced carpenter or handyman and they may help you. Also, you can plan for reselling your old furniture and purchase smart furnitures that take less space and offer more features.

Restructuring Your House

Changing the house structure is one of the most effective ways to make use of all your carpet area. It is obviously the most expensive ways among the others – but the result also is highly satisfying. So, it’s up to you, what you’ll choose.

But, planning to install tiles in the kitchen and bathroom, working on space management, improving security, fixing damp issues and damp marks and so on can add high value to your house.

Improve The Exterior Look

Every person has their own fascination when it comes to look of the interior. But, for exterior, a clean appearance and good protection is mostly enough. So, leave the interior part for the buyer and invest some money on exterior painting, says a waterproofing contractor in Kolkata. It will instantly boost the price of the building by creating a solid ‘first impression’.

Fix Leakage Issues

Think as a buyer! You visited a house for buying it, and found water dripping out from taps and pipe joints. How would you evaluate the condition of the structure?

But, how do they damage such a strong asset? What kind of mistakes they do? Here is a quick guidance.

Installing Solar Panel & DTH

Both solar system and DTH are important investments for your home. But, they need to be installed on the roof through drilling. As said by our structural engineer, mostly the person who installs these don’t care about your building structure and focus more on the appliance. Water keeps getting into your building’s core areas through these holes and makes those parts weaker various way.

Setting Up Plumbing System

Yup, one of the most important investments that you do after developing your home. Indian home owners, mostly hire plumbers once their home development is completed and so the plumbers has to make hole through your walls to create the connection. Unfortunately, these professionals can’t seal the gaps as efficiently as home developers. So, your home becomes vulnerable to rodents, termites and other types of concrete issues due to getting the top layer of your structure opened, says a damp proofing expert at Procon Technical Services.

Installing New Bathroom Fixture

Whether it’s a new geyser, shower or any other bathroom fixture, you need to do it with top finishing. Otherwise, moist of your bathroom will get soaked through these scars of your bathroom’s wall. It can cause saltpeter infection in your bathroom wall and can spread to the nearby room walls very rapidly. So, make sure you have waterproofed your walls properly after such new installations.

Hanging a Wall Paint

So, you have just purchased a new oil-paint for your drawing room to hide the blisters on your wall paint, right? But, do you know that blisters on wall are signs of damaged paint or damping. You must hire professional damp proofing services in Kolkata to fix the damping issue or have to go for a fresh coat of paint if it’s not a damping issue. Well, you of course can hang the wall paint and compliment your house interior.

Acid Cleaning

Cleaning your bathroom is one of the common habits of Indian home owners. These hygiene conscious people get a fresh feeling by cleaning their bathroom using strong acids. But, do you know that most of your bathroom materials react badly with acid? Yes, in long run, it damages the bathroom floor and other fixtures and you may face issues like leakage — especially in the corner areas where traces of acids remains even after flushing with water. So, as per a structural engineer in Kolkata, it’s best to use some mild herbal acid or use some detergent powder. It may make your task little tougher; but after-all it’s good for your home’s health.
