Grout meaning is the process of injecting a fluid material into cracks, voids and fissures to fill them. It is a thin mortar used to seal joints between tiles, masonry units or rock constructions. Grouted meaning the past tense of grouting, referring to something that has undergone the grouting process.

Grouting Works

Grouting is a crucial process in construction that involves filling gaps, voids, or cracks in surfaces with a binding material. There are several types of grouting works, each suited for specific applications:

  1. Cement grouting: A mixture of cement, water, and additives used for filling larger voids and stabilizing soil.
  2. Epoxy grouting: A durable, chemical-resistant option ideal for industrial settings and high-stress applications.
  3. Tile grouting: A fine cement-based grout used to fill joints between tiles in bathrooms, kitchens, and other tiled surfaces.
  4. Sanded vs. unsanded grout: Sanded grout is used for larger joints, while unsanded grout is better suited for smaller joints and vertical surfaces.
  5. Micro-fine grouting: A high-performance, ultra-fine grout used for delicate repairs and precision applications.

Selecting the appropriate type of grout based on the project requirements ensures a strong, lasting bond and a successful outcome.

What is grouting?

Grouting meaning in construction refers to using grout to seal joints and gaps in buildings, dams, tunnels, and other structures.

Grouting meaning in english is the same as the verb “to grout”, which means to fill in gaps or spaces with a grout material.

Define grout – It is a cementitious or chemical fluid used to strengthen foundations and seal joints by filling voids and binding particles.

Grouting meaning in civil engineering refers to the use of grouting to improve geotechnical properties of soil and rock, providing increased strength and impermeability in foundations and earthworks.

Grouting is an essential process in civil engineering construction projects like tunnels, dams, and bridge foundations.

According to english dictionary, grout means- 

to put a thin line of mortar in the spaces between tiles


The cambridge english dictionary defines in a sentence as present and past participle of verb,

an adjective of grout. It is nothing but the process of filling the gaps in between the tiles or any structure with grout. 

The collins english dictionary gives the message of grout as 

Grout is a thin mixture of sand, water, and cement or lime, which is used to fill in the spaces between tiles that are fixed to a wall.


Meaning of Grouting

When it comes to tiles grouting meaning, it refers to the process of filling the spaces between tiles with a specialized material to create a seamless and water-resistant surface. Grouting meaning in Hindi, Kannada, and Marathi translates to the same process of filling gaps or joints with a binding material.

This technique is widely used in the construction industry to enhance the strength, stability, and durability of buildings, bridges, and other infrastructure.

Grouting in civil applications helps to prevent water infiltration, improve soil stability, and provide support to existing structures.

Grouting Meaning in Civil Engineering

Interestingly, grouting urban dictionary defines the term as a slang for the act of filling in gaps or holes, often used in a figurative sense. On the other hand, the expression the opposite of grout would be to remove or leave gaps and spaces unfilled.

Grouting is a method of injecting cement or mortar into the spaces between tiles, rocks, or other materials to create a solid, cohesive mass.

According to the Cambridge English Dictionary, the definition of grout is a mixture of cement or lime with sand and water, used to fill in the spaces between tiles or masonry.

The verb form of grout means to fill in with cement or mortar. For example, in the sentence “The grouter carefully grouted the tiles,” the word grout is used as a noun. The old English origins of the word “grouts” referred to coarse meal or coarse grains.

In engineering and civil construction, the ratio of cement to water in grout is crucial for its strength and durability.

The Cambridge Advanced Learner’s Dictionary explains that grout is often a thin mortar used to fill in the spaces between stones or bricks in masonry.

It can also be used to seal and clean shower walls. Grout lines are the spaces between tiled surfaces that are filled with grout to secure the tiles in place. 

What is Grouting Meaning in Construction?

The idea is not new, yet it is constantly changing with the advancements in  materials and construction techniques. Grouting work is  particularly valuable in mining works, foundation works, seepage control, soil stabilisation etc.

Grouting tools of various types like grout gun,grout sponge,grout mixture etc .are  used for applying grout,according to the nature of the work and the area to be grouted. 

It is generally limited to zones of  relatively small volume and in special problems. It is generally adopted in both temporary and permanent works.

grout meaning and definition

What is grouting Meaning – British Dictionary?

The grouting meaning in construction is the process of filling the voids, spaces or gaps by introducing a coarse fluid mixture called GROUT into the soil or rock in order  to strengthen it.

Typically, the mixture consists of cement, sand, or it may be a specialist grout product. It serves two purposes: to strengthen the structure by filling in any gaps or voids and to enhance appearance by establishing a smooth, uniform surface.

The choice of grouting technique depends on the specific needs of the project, such as the type of materials being used and the environment in which the structure will be located.

Grout Definition and Example

The basic principle is to use a fluid mixture, such as a mix of cement, sand, water, or specialty grout products, to fill any spaces or voids between two surfaces or materials.

Grouting meaning in civil engineering is different from common house hold translation. 

principle of grouting

Grouting purpose 

It is to strengthen and stabilize a structure by filling in any gaps or voids, which lowers the chance of settlement or structural failure.


As mentioned in the blog, for grouting works various materials such as cement, sodium silicate, resins, acrylics etc. may be used.

Grouting of rockmass, in general, is carried out with cement and water mixture. However, if grout intake is very high, the grout mix may be thickened by using inert and non-cementitious material like Pozzolanas, clay or bentonite.

Admixtures (fluidisers, plasticisers and superplasticisers) are also used in order to improve the performances of the grout in terms of penetrability, strength, stability, accelerated setting and resistance to washing out.


The arrangement of the grouting equipment arrangement shall be done for continuous circulation of grout of uniform consistency throughout the grouting system and to permit accurate pressure control. Main equipment required for grouting operations are:

High-speed, high-shear mixers are used to obtain a uniformly mixed and dispersed grout and the agitating equipment used can maintain the grout in a uniformly blended suspension.

Grouting pump should be capable of pumping and injecting grout, including grout to which sand is added, if required, without pressure fluctuations at the collar of the hole. Grouting pumps shall be equipped with a pressure limiting valve to prevent sudden pressures.

Packers are required to be fixed in a grout hole at any depth to isolate a section of hole for grouting. Packers can be of pneumatic or hydraulic expansible tube type, or made with mechanically manipulated rings of rubber, leather or other suitable material. Packers shall be designed such that they can expanded to seal the holes at the specified elevations and shall be capable of withstanding grout/water pressure.

Grout Mix

Cement grout mix suspensions are identified with water cement ratio (W/C). For rockmass grouting, thin suspensions (W/C > 5) is preferred by some with the assumption that thinner suspensions can easily penetrate finer openings.

However, thin mixes are generally unstable, which may lead to bleeding and thus resulting in lower penetration and strength.

Floor Grout Meaning

It is observed that the grout penetration greatly depends on the size of the cement/solid grains rather than on the water content of the suspension.

The cement with Blaine number 3500 sq. cm/g shall be preferred for obtaining stable mixes for ordinary grouting procedures. For extraordinary requirements, superfine or microfine cements with much higher Blaine number may also be required.

Based on experience it is found out that stable cement suspensions (W/C < 3) shall be preferred with superplasticizer additives to reduce viscosity required to allow high penetrability and lower grouting pressures.

What is Grouting in Civil Engineering

It is the process of filling the concrete gaps and improving the strength of the structure. The mortar used is made of cement paste or injecting material and is widely used in building construction.

The grout is thin for tiles. It is used to repair the cracks and prevent water from going inside the concrete or building material. To clean the remaining, you can use a soft brush. 

It is one of the most economical and beneficial services for civil engineering. In summer, the cracks may widen up and you need to fill it with grout and seal it. Property might become damaged, if the grout mixture is of not the right proportion. 

Grout is also used in wide scale applications like dam construction, road construction, pile construction etc, which are parts of civil engineering. Grout is mixture sand, water and cement added with a chemical additive to make the right mix and hardens with time.

Lot of environmental applications can be found relevant to civil engineering. It prevents seepage and thus protects the surrounding structures.

It involves choosing the right grout mixture and application technique for the job at hand, making sure the surfaces to be grouted are spotless and free of debris, and applying the grout at the right pressure and flow rate.

 To guarantee that the grout mixture fills the gaps or voids entirely and uniformly, it is crucial to control the grout mixture’s pressure and flow rate.

Overall, the principle is to provide a strong and stable structure by filling in gaps or voids between two surfaces or materials, thus improving the overall performance and longevity of the structure.

Grouting characteristics

The three basic functions to be satisfied as follows.

  • Penetration or permeation – grout should easily penetrate into the voids or spaces in the soil.
  • Should be resistant to chemical attacks.
  • Compaction or controlled displacement – in this the grout should remain as a mass and exert pressure on soil or rock.
  • Should be able to develop sufficient shear strength to withstand Hydraulic gradient  or uncontrolled displacement developed during injection.
