Aftek Penaflow UW Grout

Non-Shrink Underwater Grout.

RLA PENAFLOW UW Grout is a high-performance, non-shrink cementitious grout specifically designed for underwater and wet-area grouting applications. Formulated with anti-washout technology, it resists dispersion and material loss when placed in submerged or flowing water environments.
Engineered for structural and civil use, PENAFLOW UW Grout delivers excellent strength development, controlled expansion and superior cohesion in challenging wet conditions. It is ideal for marine, infrastructure and repair applications where conventional grouts may fail due to washout or segregation.


Uses
•Underwater grouting and repairs
•Marine and tidal zone applications
•Bridge piles, pylons and structural supports
•Grouting in wet shafts, pits and excavations
•Filling voids in submerged concrete structures
•Seawalls, jetties and wharf repairs

Benefits
•Anti-washout formula prevents material loss underwater
•Non-shrink properties reduce settlement and voids
•Excellent cohesion and resistance to segregation
•High early and ultimate strength development
•Pumpable and flowable for difficult access areas
•Suitable for structural and civil applications
•Designed for harsh wet and marine environments


Coverage
•Water addition and yield will vary depending on required flow and placement method
•Coverage varies based on void size and placement conditions
•Designed for medium to large volume grouting in submerged environments

Application
•Ensure substrate is clean, sound and free from loose debris before placement
•Use appropriate formwork to contain grout and prevent washout
•Mix using a high-shear mechanical mixer for best performance
•Add powder to measured water and mix until smooth and cohesive
•Place using pump, tremie pipe or controlled pour methods to minimise turbulence
•Avoid excessive agitation during placement
•Allow proper curing in accordance with project specifications
