STEIN TEC® Bedding Mortar BM 04

STEIN TEC® Bedding Mortar BM 04

Bedding Mortar BM 04 is a pre-mixed bedding mortar (available in the silo including mixing technique or as bag ware) for pavements and slabbed surfaces, which can always be optimally processed freshly. Therefore, problems like over-storing / demixing or time lag belong to the past. Its ultimate strength is achieved reliably and without variations in quality at professional processing.


high compressive strength
high adhesive tensile strength
high water-permeability
low-shrinkage and low-stress
polymer modified
very good processability


STEIN TEC® Bedding Mortars are to be mixed either using the horizontal flow-mixer mounted at the silo, or if delivered as bag ware in the positive mixer with clear cold water only in earth-moist texture (for more information see technical data sheet or print on bag). The paving blocks resp. slabs shall be finally set in the bedding mortar by hammering in correct height and alignment in the projected joint distance. By piling strike, a compaction of approx. 25 per cent of the mortar bed, professionally prepared, must be achieved underneath the element (required gross density of hardened mortar 1.900 kg/m³, cp. Technical data sheet). The mortar bed must be raised up by that slump.

The paved / slabbed surface must be cured. For further information refer to the technical data sheets of the corresponding STEIN TEC® Bedding Mortar.
