SikaGrout Ultra 20KG – High Performance Cementitious Grout

Description

SikaGrout Ultra – Ultra High Strength Cementitious Grout

SikaGrout® Ultra is a premium, ready-mixed, high-quality cementitious grout designed to deliver exceptional performance in critical grouting applications.

Key Features:

• Self-Levelling: Ensures effortless application and uniform distribution.
• Shrinkage Compensated: Expands in two stages (Class A and C) to counteract typical shrinkage associated with Portland cement grouts.
• High Early Strength: Achieves 35 MPa within 24 hours.
• Ultra-High 28-Day Strength: Exceeds 100 MPa, providing long-term durability.
• Non-Segregating and Non-Bleeding: Maintains consistency and integrity during application.
• High Impact and Thermal Resistance: Withstands demanding environmental conditions.
• Non-Corrosive: Safe for use with steel and iron components.

Applications:

• Grouting projects requiring compressive strengths up to 100 MPa.
• Static load grouting for machine base plates.
• Anchor bolting and bridge bearing pads.
• Pre-cast concrete sections and shear key grouting.

Equipment:

SikaGrout® Ultra must be mechanically mixed using a mechanical grout mixer or a suitable drum mixer. The grout mixer will reduce the chances of the mix becoming lumpy or aerated. Smaller quantities should be mixed in clean drum using an electric drill and spiral drill and spiral mixer at a speed of approximately 500 rpm. DO NOT MIX BY HAND or MIX PART BAGS.

Mixing:

Add 2.7 litres of water per 20 kg bag.

Add the powder to the total water while mixing.

Mix until the grout appears homogenous (5-6 minutes). Allow to stand so any entrapped air can escape. Do not add more water to increase flow of the grout if a mix has stiffened due to time delays. If the grout is unworkable discard.

Application:

SikaGrout® Ultra can be placed by either gravity flow or by pump. It is essential that proper placing on the job site is practised to ensure placement is completed without problems. Sufficient labour, grout and equipment must be present to ensure continuous placement.

Gravity:

Mixed grout should be poured one side of the void to avoid air entrapment. Grout is best poured over short distances to ensure this. Use a suitable header box, maintaining the grout head at all times to ensure continuous flow.

To facilitate grout compaction and top plate contact, use rodding, tamping or flexible strapping in short strokes while maintaining an adequate head of grout. Do not vibrate as this will cause segregation. Any adjacent machinery or equipment causing vibration should be shut down until initial set (approx. 3 hours).

Pumping:

When pumping SikaGrout® Ultra, ensure the pump is suitable for the grout consistency and for the distance and height it is to be pumped. A positive displacement pump is recommended. Place grout by pumping into the farthest corner, filling the space gradually. Ensure that air is not entrapped under the base plate.

Curing Treatment:

Suitable curing methods such as plastic sheet, wet hessian, liquid membrane (eg, Antisol curing membranes) etc. must be used to protect the freshly applied grout from the drying effects of sun and wind. Curing must commence immediately after placement, and continue for at least 7 days. Curing is vital to the ultimate performance of grout as it allows optimum strength development and ensures tight contact with the baseplate.

Cleaning Of Equipment:

Remove uncured SikaGrout-Ultra from tools and equipment with water. Hardened material can only be removed mechanically.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
