A.R. glass fibre structural mesh Kimitech Wallmesh HR-HD Kimia

What it is

Kimia Kimitech WALLMESH HR-HD preformed structural mesh, made of alkali-resistant (A.R.) glass fibre impregnated with thermosetting resin. It weighs 510 g/m², has a 38 x 38 mm mesh and an average elastic modulus of the impregnated mesh of 23 GPa; after 1000 hours in humid or saline environments it retains over 85% of its strength. It is CE marked to EAD 340392-00-0104 for CRM reinforced plaster systems.

FRP and FRCM structural strengthening is a system of fibre fabrics, meshes and connectors, applied with resins or mortars, that increases the strength of beams, columns and masonry.

What it is for

Used for strengthening masonry and concrete structures and for structural fixings, where the fixing is load-bearing and must be calculated.

How to use it

Strengthening must be carried out to a design by a qualified engineer. Remove render and deteriorated material, repair the substrate and apply the primer; then apply the first coat of resin or mortar, lay the fabric or mesh taut and free of air bubbles and cover it with the second coat. Insert the connectors into clean holes filled with resin; handle resins and primers with gloves and safety glasses.
