New wall materials are widely used in the construction industry, which have green environmental protection. But the cracking and leakage wall causes the building function decline, heat preservation and insulation failure, which hinder its comprehensive promotion. Some regularities and conclusions had been got through several researches on the engineering application of new walls anti-cracking and anti-leakage performance. Researches are based on many aspects, such as design calculations, structural measures and detecting techniques. The summary in this paper includes: material crack propagation mechanism, experimental investigation of shrinkage of concrete brick walls at different ages, new walls in-field test of surface permeability, image processing of wall crack etc.
