Preparation & Application

Preparation

All surfaces should be clean and sound. Concrete surfaces must be free from any contamination including oil, grease, laitance and dust - and for maximum bond the surface should be roughened and presoaked with clean water.

Immediately prior to grouting, remove surface water including that in bolt holes or recesses.

Metal surfaces must be free from rust, scale, oil or grease but removable metal shims should be lightly oiled.

Bolt holes must be blown free of dust, water or any loose material.

Formwork should be well sealed to prevent leakage.

Mixing

Mixing and placement can be carried out between +5°C and +25°C. In service, webercem grout eco will perform similarly to other cementitious mixes based on Portland cement in the temperature range of -20°C to +150°C.

Mixing should be carried out in a proprietary grout mixer or by using a medium speed drill (650 rpm) with an MR4-type helical attachment.

Do not use more than the maximum stated water adddition.

Application

When pouring, the area to be grouted should be shuttered and a header box used to maintain a grout head of 150 - 200 mm during the pour.

Machine mixing is recommended to achieve continuous pouring. For large applications webercem grout eco should be placed by pump, having been formulated to give a 30 minute working time.

Continuous grout flow is essential and sufficient grout and water should be available to be mixed to ensure there is no disruption during placement.

Where the thickness of grout is 100 - 200 mm, the grout may be bulked out with clean, single-sized aggregate by mixing in up to 10 kg of a 6 mm rounded aggregate per 25 kg bag. However, other Weber products are available, which may be more suitable. Please contact our Customer Services Department for details.

Avoid leaving unconfined areas of grout proud around bearings etc.

The grout around the edges of baseplates must be finished flush with the sides by cutting the grout while still green after stripping formwork.

Cracking may result in areas where there is no restraint.
