Technical Information
Product Description

Vetogrout GA516 is supplied as a powder admixture. The material is a combination of a plasticising agent and a gas producing expansion medium. The plasticising agent allows the use of a reduced water/cement ratio with consequent increased strengths and durability. The expansive  medium counteracts the natural settlement and plastic shrinkage of the grout and aids stability and cohesion. Sufficient restrained expansion is developed to ensure a high degree of interfacial contact.

Advantages
  • Gaseous expansion system compensates for plastic shrinkage and settlement in properly designed cementitious grout.
  • Reduced water/cement ratio mixes in the grout mix ensures low permeability and long term durability in service.
  • Gives high grout fluidity with low water/cement ratio, thus making placement or injection of the grout easy.
  • No metallic iron content to corrode and cause staining or deterioration due to rust expansion in the grout.
  • Composition allows high early strength development in grouts, without the use of chlorides.
Compiliance Standard
  • BS8110 part 1 : 1985

Application Information
Instructions for use

Mixing
For best results a mechanically powered grout mixer must be used. For quantities up to 50 kg a slow speed drill fitted with a high shear paddle is suitable. Larger quantities will require a high shear vane mixer. It is essential that machine mixing capacity and labour availability is adequate to enable the grouting operation to be carried out continuously. This may require the use of a holding tank with provision for gentle agitation to maintain fluidity. The selected water content should be accurately measured into the mixer. Slowly add the cement (and sand if required) and Vetogrout GA516. Mix continuously for 5 minutes, making sure that a smooth even consistency is obtained.

Application
Areas to be grouted should be prepared to ensure substrates are clean, sound, and then pre-wetted. The unrestrained surface area of the grout must be kept to a minimum. Place the grout within 20 minutes of mixing to gain the full benefit of the expansion process. Adopt usual placing or pumping procedures ensuring a continuous operation.

Curing
On completion of the grouting operation, any exposed areas which are not to be cut back should be thoroughly cured by means of water application, Concure curing membrane or wet hessian.

Cleaning
Grouts mixed with Vetogrout GA516 should be removed form tools and equipment with clean water immediately after use.

Surface Preparation

All contact surfaces must be free from oil, grease, free standing water or any loosely adherent material. Concrete surfaces should be cut back to a sound base. All dust must be removed and bolt holes or fixing pockets blown clean of any dirt or debris.

Limitation

Vetogrout GA516 is incompatible with High Alumina Cement.

Additional Information
Health & Sefety

Vetogrout GA516 Contains resins which may cause sensitization by skin contact. Avoid contact with skin and eyes and inhalation of vapor. Wear suitable protective clothing, gloves and eye/face protection. Barrier creams provide additional skin protection. Should accidental skin contact occur, remove immediately with a resin removing cream, followed by soap and water. Do not use solvent. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice. If swallowed seek medical attention immediately. Do not induce vomiting.
