SikaGrout-UW is a ready to use, class A cement-based grout for applications underwater. The grout, when properly mixed, will have no significant ‘wash out’ of the cement phase. SikaGrout-UW is a blend of Portland cement, carefully selected and graded aggregates and Sika admixtures enabling it to achieve excellent flow, non wash-out characteristics and high compressive strength.
SikaGrout-UW can be used individually for underwater grouting or as a system in conjunction with Sika Pile Jacket systems or other confinement jacket repair systems for rehabilitation of concrete, steel and timber piles in marine applications.
- Bridge Column repairs.
- Piles repair.
- Underwater grouting.
CHARACTERISTICS AND ADVANTAGES
- Good resistance to ‘wash-out’ of cement phase when placed underwater.
- Effectively displaces water.
- Shrinkage compensating properties.
- High early & 28 day strengths.
- Good impact, vibration and thermal resistance.
- Non-corrosive to steel or iron.
- Used with Sika Pile Jacket and other pile jacket systems.
SikaGrout-UW must be mechanically mixed using a mechanical forced action
grout mixer. It is essential that mixing is carried out in a manner so that the
grouting operation may continue without interruption.
Always add powder to the water. Place approximately 70% of the total water content into the bucket.
Add powder slowly to the water while mixing till bag is empty. Then slowly add remaining 30% of the water component is to be added while continuing to mix.
The total water required for each 20kg bag of powder is 3.7 litres. Mix the
grout until it appears homogenous (3 to 5 minutes). Allow to stand so any
entrapped air can escape. Do not add more water to increase flow of grout if
a mix has stiffened due to time delays. If grout is unworkable, discard.
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.
