Advanced 1H Nuclear Magnetic Resonance (NMR) relaxometry is a valuable tool for the characterization of building materials like waterproof mortars. Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence method was used for the measurement of four samples (C65, P88, P288, AQSE) of waterproofing mortars at 7 days after preparation. In general, four dynamics components were observed for the T2 Laplace distributions at 7 days after preparation. Their characterization shows the evolution and the mobility of protons in the samples. In general, these peaks have T2 values which can be associated with bound water, free water in small pores, and free water in medium and large pores. The Scanning Electron Microscopy (SEM) was measured for all samples and correlated with NMR parameters.
