To install extensive cementitious, polished concrete floors with only a few joints (terrazzo), a double-layer bonded screed is applied wet-on-wet or after hardening of the bottom layer. In the...
Use of lattice girders in reinforced-concrete floor plates is a widely practiced method of construction for conventional high-rise building structures. An estimated 70 % of all floors in these...
Macroporous lightweight concretes whose thermal insulation effect relies on a certain ratio of air voids in the material are subject to physical limitations that have been virtually exhausted by...
Worldwide, concrete is second only to water in terms of its quantities used: each year, approx. 10 billion tonnes of concrete are required. More than 900 million tonnes of old concrete from...

The Energy Saving Ordinance (EnEV) has left its mark also on the construction of floors for high-rise buildings. Control of panel heating and ventilation systems is one of the absolute requirements of...
Application example 1:
Strengthening reinforced-concrete columns
Ducon (ductile concrete) consists of numerous layers of reinforcement in the form of point-welded wire mesh (mesh width approximately...
