F11 is a polymer-modified waterproof mortar offering strong impermeability, bonding and durability for industrial and civil waterproofing projects.
Summary Benefits at a Glance
Excellent waterproofing and impermeability performance
High compressive, flexural and bonding strength
Crack resistance and shrinkage control
Durable against aging, alkali, heat and freeze–thaw cycles
Product Introduction
F11 Polymer Waterproof Mortar is a composite cementitious material enhanced with polymers, selected cement and functional admixtures. It provides strong adhesion to concrete substrates, excellent impermeability, crack resistance and shrinkage compensation. With outstanding durability against aging, thermal cycling and freeze–thaw damage, F11 is widely used in roofs, basements, tunnels, water-retaining structures and waterproofing of industrial and residential projects.
