What is Grouting ? Its 2 types & Advantages
What is grouting ? Grout is the mixture of sand, cement, and water or chemicals used to fill gaps.
Grout is used in repairing concrete cracks, gaps in tiles, filling seams, gaps for selling and waterproofing feeling, and soil stabilization.
Grove is also used to provide additional strength to the foundation of load-bearing structures. Finally, the grating is generally the process of injecting pumble material into the design to change its physical properties.
Types of material are used for grouting.
Cement grouting:
cement grouting is the injunction under grout or cement to fill the fractured or voids in the soil, concrete structure, or rock unit.
Chemical grouting:
this type of grouting transforms granular soils into sandstone- such as masses by filling the voids with little viscosity, non-particular grout.
This type of grout is an injection under pressure through ports. And grout permeates the hardened soil, creating sandstone-such as mass.
Bentonite grouting:
is a specially formulated sodium bentonite. It is used for water well grout, drilling hole abandonment, sealing monitoring well casing, or geothermal grout.
Types of grouting
1. G1 grouting
This type of grouting is usually for steel structures, small pumps, towers, and non-vibrating machinery. Still, the precise application of grout type to every location will be according to relevant drawings.
The grout will be free-flow-flow cementless grout, nonshrinking with small compressive strength at least equal to the concrete foundation, but strength not less than 30 N/ MM2 in seven days and 40 N/ mm2 in twenty-eight days and will be less than.
2. G2 grouting
G2 grouting shall be used generally in the prefabricated structure of concrete, compressors, and other more heavy equipment subject to vibration and column bearing plates of rich designs.
This type of grout shall be proprietary non-compressible cement high strength grout,e.g., FOSROC, S
conbextra GP2, Sikka, and MC-bauchemie emcekrete or likewise and approved by EIC. The compressive strength of the grout minimum will be fifty N/ mm2 in seven days, and in 28 days will be 60 N/ mm2.
Characteristics of grouting
- Well, bond to concrete.
- Substrate preparation
- Able adjustment
- Excellent flow characteristics
- No segment or bleeding
- Final strength high
- Easy to mix; only add water.
- Non-corrosive
- Not flammable
- Non-toxic
- Impact and vibration resistant
- Easy to use
- Shrinkage compensated
- Able adjustment fixture
Types of grout for ceramic tile
1. Unsanded grout
Unsanded grout is used for wall tiles where the joints are ⅛ inches to ⅜ inches wide.
2. Finely sanded grout
Finely sanded grout is used for tiles where the joints are ⅛ inches to ⅜ inches wide.
3. Quarry type grout
Quarry type grout is the same as finely sanded grout for ceramic tiles and excepted that the coarsest grade of sand is used.
This type of grout is used for a joint that are ⅜ inches to ½ inches wide such as those used with saltillo tiles.
4. Epoxy grout
It consists of epoxy resin and hardened.
The epoxy grout for ceramic tiles is highly resistant to chemicals and stains and has tremendous bonding strength.
Process of grouting
Choose the grout color.
Apply the grout.
Hold the grout float at an angle of 90 degrees.
Wipe the tile with the damp sponge.
To remove the haze, use a damp cloth.
Apply the sealer
Caulk along baseboards and walls.
Grouting material
The grout is a composite material that consists of cement, sand, and water. It is used for felling the voids under the machines and other elements, sealing the joints and opening in surface, and reinforcing existing structure.
Cement grouting
Cement grouting is the injunction under grout or cement to fill the fractured or voids in the soil, concrete structure, or rock unit.
Advantages of grouting
- Grout can be done on any ground condition.
- Grout does not induce vibration, and it can be controlled to avoid structural damage.
- Improvements in the ground structure can be measured.
- It is beneficial for low headroom applications.
- It can install existing walls.
- Grout is useful for limiter space.
- It has been used for slab jacking that deformed foundation.
- It can control groundwater flow, seepage, and hazardous waste materials process and its types.
