New Results and Aspects in the Area of Seal Wall Research

This paper is based on current new research into seal wall engineering at the University of Hannover. I shall for reasons of time and space refrain from describing the known and often published systems and principles of seal walls. The results I shall be discussing concern the following problem: Approaches to testing suitablity of seal wall mass resistance to aggressive waste disposal seepage waters.Utilization of seal wall excavation material for producing flexible surface seals.Gas permeability of seal walls, test principles and trends of results.
