How to check construction quality of a building?

Nobody wants to buy a low quality construction house or flat or building, right? Everyone wants a good quality construction. So before buying a house, its everyone’s right to check the construction quality of a building. If you are buying new or planning to invest in an under-construction project, checking and measuring the construction quality of the project should be of paramount importance. When investing in such a property, it is advisable to make a surprise visit to the construction site and check the construction quality.

As of Section 14 of the Real Estate (Regulation and Development) Act, 2016, clearly lays down that it is the promoter’s responsibility to rectify any structural defect within a period of five years.

Here the few things you need to check about the quality of construction which you can do by your own.

Investigate the Soil

The quality and type of soil on which the building is built are very crucial. The soil type differs from place to place and the type of soil determines whether it can bear the foundation of a high-rise. Clay-rich soil and black cotton soil are examples of some forms of soils which are not recommended for construction as they tend to expand, swell and shrink depending upon moisture or water. A soil test is conducted before the construction process begins. You can ask for a copy of the test from your developer.

Determine the construction design

Being a layman, it may be difficult for you to rightly understand the structural design of the building. Take the help of an expert to determine the design created by the architect. It is important to assess the property thoroughly for the strength to resist the earthquake of a certain magnitude.      

Check the concrete measure

The strength of concrete determines the load a structure can bear and carry. Usually, developers monitor the quality and strength of the concrete, but at times, it gets difficult to prepare the mix and check the concrete every time. In such cases, it is always better to opt for ready-mix concrete as an alternative.

Look for plastering quality

Ensure the toilets are leak proof with the help of two-level water stagnation checking. Check if terrace flooring was done by laying brickbat coba and Terracotta tile to prevent heat transmission to the top dwelling floor. The uneven cracks on the wall plastering is definitely a bad sign. Also check if the paint used is of quality as it impacts the longevity of walls.

 In order to check by yourself, carry a nail. Drive the nail to the plaster and if it goes in easily, the quality of mortar is bad. If the nail bends the mortar quality is good. In case of toilets where you face leakage problem the most, pour water on the floor to check water stagnation and availability of proper slope.

Fixtures and finishing

Check for the quality of bathroom fittings, wires, electrical fittings, water pressure, pipe fittings, functionality and cleanliness of sanitary fittings etc. Also, check the material of the window and door locks and if the windows and doors are functioning properly. You can also inquire about the brand of tiles and marbles used.  To understand if the flooring is done right, you can do a quick test by rolling marbles on the floor gently. 

Study the wall thickness

The specifications for the wall thickness are mentioned in the brochures and the legal documents of the building and house. Hence it is important to check whether the finished walls match the specifications.


As I mentioned above Section 14 of the Real Estate (Regulation and Development) Act, 2016, clearly lays down that it is the promoter’s responsibility to rectify any structural defect within a period of five years. And the property owners should be aware of this prior.

Check for quality of groundwater

One of the most pertinent issues that have encapsulated a significant time of both, the real estate developers and the public authorities is the issue of groundwater. The susceptibility of some of the economically most vibrant cities of India to depleting levels of ground-water has rung a warning bell for real estate companies as much as it has for homebuyers. For this very purpose, the homebuyer should check for the quality of groundwater and the treated water from WTP (Water Treatment Plant) and also check for the same from the third party lab test report.
