Preparation & Application


All surfaces must be mechanically sound, dry and clean. All saw cuts should be free of slurry, dirt, dust, grease, oil or any other contaminants.

Saw cuts should be as narrow as possible, depending on cable size.

Surfaces should provide a textured, mechanical key for full bond.

The edges of slots should be cut sharp.

New concrete should be at least 7 days old prior to grouting.


Pour the resin into a clean plastic or other suitable container and gradually add the small bag containing hardener. Mix thoroughly. Now add the large bag containing filler and mix until a uniform colour and consistency is achieved. Small quantities can be mixed by hand using a spatula. Large quantities should be mixed mechanically.


Immediately after mixing, pour webertec cable grout into the prepared slot using a funnel or tun dish.

Top up as required within 2 hours.

webertec cable grout is not intended for filling large voids. For gaps wider than 16 mm, use webertec cable grout mixed with clean, dry, rounded aggregate up to 5 mm diameter. Up to 10 kg of aggregate can be used for gaps not exceeding 30 mm.

Setting times are dependent upon temperature. These are shown in the Technical Data table.


Clean tools with webertec solvent 3 before the grout sets.
