SURFACE PREPARATION

Surfaces should be clean, sound and free from oil, grease, laitance and loose particles. Metal surfaces should also be clean & free from rust, oil & grease.

MIXING

C o n g r o u t  1000  should be mixed using a suitable mixer. For flowable consistency use a slow speed <400

R.P.M. hand drill and paddle. For large works use a high shear vane grout mixer. Drum mixers may not mix sufficiently.

Powder should be added to the pregauged clean water.

For J rote of 7 seconds approx. 16% of water by weight of Congrout 1000 should be used. Do not add more than the maximum water content. Mix for up to 5 minutes.

APPLICATION

Ensure the substrate is correctly prepared. No contamination and saturated with water at least 3 - 4 hours prior to pouring the grout. No free water should be left. During application ensure air entrained into the grout

is able to escape through relief holes. Maintain continuous head when base-plate grouting. Mortar flow should not be interrupted. Formwork should not allow grout loss.

Ensure there is no water standing in bolt holes. If possible grout anchor bolts first then the mortar bed in a second operation. The distance between anchor bolt and substrate should be at least 3 x max. diameter of mortar aggregates approx. 10 mm. A cable or chain may be used to make sure that all cavities are filled.

IMPORTANT

Use Congrout 1000 with minimum gaps of 5 mm. and maximum depths of 125-150 mm. Temperature will affect setting time and strength gain. Normal curing practice should be maintained.
