STEIN TEC® Bedding Mortar BM 04 S

STEIN TEC® Bedding Mortar BM 04 S

Bedding Mortar BM 04 S is a pre-mixed bedding mortar (available as silo including mixing technique or as bag ware) with a very fast setting and hardening rate. It is suitable for heavily used surface pavements that need to be used at an early stage. It surpasses the normal-setting Bedding Mortar BM 04 in every property.


quick hardening
early loadable
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.
