Penatech HS Plus
Very High Strength Class C Cementitious Grout.
Very High Strength Class C Cementitious Grout.
Aftek Penatech HS Grout plus is a high strength, precision Class C grout. Non shrink dual expansion compensates for shrinkage in both the plastic and hardened state.
Penatech HS Grout plus complies with US Corp of Engineers Specification of non-shrink grout, CRDC 621-82A and ATSM C1107-91 (Type C).
The substrate to be grouted must be clean, sount and free from dust, oil, grease, curing compounds or any foreign matter that will affect the gout adhesion bond. Bolt holes and anchor points must be clean and free of water.
All prepared areas must be saturated with water for a minimum of 4 hours prior to grouting. This will reduce the porosity of the substrate. Prior to grouting, ensure all excess water is removed and all holes must be free from water and no puddles of water are present. If grouting under base plates, it is imperative that bleed holes or venting holes are provided (this will eliminate pressure build up in a confined area).
It is essential that the formwork to be constructed is leakproof and water tight. In order to achieve this it is recommended that foam rubber strips or a suitable sealant such as polyurethane or silicone be used underneath the formwork.
The formwork should be constructed, which will allow and ensure a grout head is maintained on the side above the level of the underside at the base plate. The formwork should allow for gravity flow of grout with a suitable grout head allowing for continuous flow between the base plate and the conrete substrate.
To ensure ease of formwork removal, the formwork should be coated with form oil or release oil prior to grouting (consult Aftek Technical Department for additional information).
For grouting requring thicknesses greater than 200mm, special procedures are necessary, such as the addition of Epilox Fillers or 10mm Silt Free aggregate can be used.
Consult your AFTEK representative for advice and addtional information.
At low temperatures below 100C , the grout setting time is extended and some bleeding may occur. The early strength gain will be dramatically reduced. However, ultimate strength will be maintained. It is recommended that the Penatech HS Grout plus and the water be conditioned to 20-250C overnight or several hours before application. This will assist in strength development.
At high temperatures greater than 300C, the grout setting time is reduced and grouting application becomes problematic due to very early setting times and reduced placement times.
It is recommended that Penatech HS Grout plus be kept in a cool environment and the use of cold water be used for mixing. It is recommended that in instances where the temperature is greater than 300C, the grouting be conducted early in the day or late in the evening and sheltered from sunlight and direct heat.
Penatech HS Grout plus is ready to use, simply requiring the addition of water.
Penatech HS Grout plus must be mixed with a mechanical mixer with a high shear mixer or a suitable drum mixer that creates a forced action mixing.
For smaller quantity mixing, an electric drill with a spiral mixing paddle is suitable. The speed drill should be approx. 500-600 rpm.
Do Not Mix By Hand
| Dry Pack/ Stiff Grout: | Add 2.2-2.6 litres per 20kg bag |
| Plastic/ Trowellable Grout: | Add 2.8-3.2 litres per 20kg bag |
| Flowable/ Pourable Grout: | Add 3.5-4.0 litres per 20kg bag |
Always add the grout powder to the premeasured water. Do not add addtional water as grout wil seggregate and bleed affecting performance.
The selected water level should be accurately measured and added to a suitable mixing container.
Add the powder (grout) to the water and mix for 3-5 minutes until a homogeneous consistent mix is obtained.
Do not add additional water other than specified above. Discard any grout that has stiffened or is unworkable.
