 Technical specifications

PowerMortar's properties have been tested in a
concrete research laboratory

Ø Excellent adhesion to stone, concrete and steel

Ø PowerMortar does not shrink

Ø PowerMortar has a high compression strength

Ø PowerMortar is resistant to freezing

Ø PowerMortar's temperature coefficient of expansion is the same as that of concrete

Ø PowerMortar is resistant to salt and chemicals

Ø PowerMortar does not contain water-soluble materials

Ø PowerMortar has low water permeability (prevents rusting of steel )

Ø PowerMortar is alkaline (prevents rusting of steel )

Ø PowerMortar is not carbonised
