Grouting Aid(M)

DESCRIPTION:

AT-GROUTING AID (M) is specially formulated hydrogen-free grouting aid. It is free-flowing powder for addition to neat cement slurry. It plasticizes the mix allowing for substantial reduction in water content without affecting the fluidity, thus improving the strength and impermeability of the grout. During the setting period of the grout it produces controlled expansion to compensate the normal drying shrinkage of cement. It ensures complete filing of voids and prevents formation of porous sections. Due to its surface-active property and volume increase during reaction even the smallest cracks and pores can be impregnated.

USES:

• AT-GROUTING AID (M) is used as an admixture for injection grouting to effectively waterproof and stop leaks in underground structures, basements, tunnels, lift wells, retaining walls, dams, water reservoirs, pressure ducts and other water retaining structures. It is also recommended for grouting pre-stressed members and wherever a non-settling, non-bleeding, expanding grout is required.
• AT-GROUTING AID (M) can also be used as an admixture for mortar without shrinkage.

METHOD OF USE:

• AT-GROUTING AID (M) is admixed with neat cement slurry of suitable consistency and injected under pressure preferably by a positive displacement pump through nozzles.
• For normal injection grouting the surface of concrete/rock should be properly sealed / packed to prevent the grout from oozing out.
• AT-GROUTING AID (M) should be mixed uniformly with dry cement.
• For concrete, mortar, rendering stone surfaces must be clean, sound and free from oil, grease, cement laitance, dust and other surface contaminants
• Apply with a float, trowel or glove-protected hand depending on application
• Compact well and finally smooth-off well with a clean steel trowel

DOSAGE:

• AT-GROUTING AID (M) dosage varies from 0.5% to 2.0% by weight of dry cement for normal injection grouting.
• For mortar dosage varies from 0.1% to 0.3% by weight of cement.
• The optimum dose depends on the nature of the work
