Baumit Beton B20 is a factory-prepared dry concrete mix designed for quick and reliable use in small and medium repair works in houses, garages, yards, and gardens. Simply add water and mix to obtain high-quality concrete with predictable strength and excellent workability. The mix is suitable for both interior and exterior applications and is an excellent choice for foundations, pathways, small footings, filling voids, and producing non-structural concrete elements.
Key Advantages of Baumit Beton B20
- Reliable strength: compressive strength ≥ 20 N/mm² after 28 days when applied according to the instructions.
- Versatile applications: ideal for sub-bases under foundations and walkways, floor screeds, filling holes and gaps, garden fences, shafts, supports, columns, lintels, and more.
- Consistent and guaranteed quality: factory-controlled recipe ensuring stable performance for every batch.
- Easy to transport and use: convenient 25 kg bag; just add water and mix manually or mechanically.
- Weather-resistant: frost-resistant and suitable for outdoor work when temperature requirements are observed.
Composition and Structure
The mix contains high-quality cement, crushed sand fractions, and functional additives to ensure optimal consistency, easy compaction, and even curing. The grain size ranges from 0.1 to 8 mm, ensuring good density and strength of the finished product.
Recommended Applications
- Repairing and/or replacing defective, non-structural concrete.
- Sub-bases for foundations, slabs, and walkways (including tiled surfaces).
- Filling holes, gaps, and chipped areas (with or without formwork).
- Creating small concrete elements for garden and home — supports, fence posts, inspection shafts, curbs, lintels, and more.

Instructions for Use
- Base preparation: check stability, levelness, and cleanliness of the surface. Compact and level if necessary. Do not work on frozen or very wet bases.
- Mixing: pour part of the water into a container/mixer, add the dry mix, and add the remaining water until a homogeneous consistency is achieved (from earth-moist to plastic). Use only clean drinking water.
- Application: transport the fresh mix without unnecessary delay and place it in position, avoiding pouring from a height over 1 m to prevent segregation.
- Compaction and finishing: compact according to the consistency and smooth the surface if needed.
- Curing: protect the fresh concrete from drying out, rain, or freezing during the first days to achieve optimal strength.
If you are planning repair or small construction work at home or outdoors, Baumit Beton B20 is the reliable choice for a durable base and long-lasting results. Its easy preparation, guaranteed quality, and weather resistance make it suitable for both DIY enthusiasts and professional builders.
