POSTAER SANDSTONE -mgE-

POSTAER SANDSTEIN -mgE-(with minor inclusions) is a medium-grained, pebble-bound Elbsandstone of yellow-brown, also gray color. Very often it is banded between yellow and/or gray and brown layers. Characteristic are isolated dark brown iron hydroxide or light gray cavernous inclusions.

POSTAER SANDSTONE is absolutely frost and weather resistant and, due to its special hardness and environmental resistance, is used in particular for architectural parts subject to high loads and splash water, such as columns, steps, floor and base slabs. It is particularly suitable for solid and profiled stonework of any kind in restoration and new construction. POSTAER SANDSTONE is the main building material for the archaeological reconstruction of the Dresden Frauenkirche.
