High Performance Non Shrink Cementitious Grout for Under Water Application.

Penaflow Grout UW is a high performance construction grout based on a blend of Portland cement, high quality graded aggregates and additives, which control expansion whilst the grout is in a plastic state. Penaflow Grout UW can be used underwater or in tidal zone application. Penaflow Grout UW will not wash out when submerged in water and is ideal for underwater concrete piling.
