21. COMPOSITE SYSTEMS FOR STRUCTURAL STRENGTHENING
MapeWrap Primer 1
Two-component epoxy primer
specifically formulated for the
MAPEWRAP system.
MapeWrap S Fabric
Unidirectional, high-strength metal fibre
fabric for structural strengthening.
MapeWrap S Fiocco
High-strength, steel fibre cord for
structural strengthening.
Planitop HDM
Two-component, high-ductility,
pozzolan-reaction mortar applied in
layers up to 6 mm thick for “reinforced”
structural strengthening of masonry
substrates in combination with
MAPEGRID G 120, MAPEGRID G 220
or MAPEGRID B and for smoothing and
levelling surfaces in concrete, stone,
brickwork and tuff.
