Buildmix Grout M40 / M60 / M80 technical dossier
Applications
- Machine foundations, rail plinths
- Anchor bolts, steel column bases
- Bridge bearings and beams
- Void filling and high-strength structural repair
- Levelling floors before tiling or timber flooring
Advantages
- Free-flowing, fills narrow gaps
- No bleeding
- Shrinkage-compensated expansion (≥ 0.1 %)
- Pre-mixed — just add water
Application steps
- Clean and saturate the concrete surface, leaving no standing water; fix tight formwork.
- Mix powder : water = 1 : 0.14 by weight (about 3.5 litres per 25 kg bag) with a mixer below 500 rpm for at least 3 minutes.
- Pour continuously from one side to avoid trapping air.
- Layers under 5 mm: use a latex–cement bonding slurry. Large pockets: add aggregate at 50–100 % of powder weight.
