A process for sealing soil formations, especially for sealing the base of a waste dump or encapsulating waste dumps or old sources of pollution. By this process, sewage sludge or river mud is mixed with water absorbent aggregate that is approximately 30-70 wt %, based on sludge or mud dry weight, forming a compressible non-hardening mixture. The resultant mixture is then applied to the soil formation and compressed mechanically, forming a non-hardening seal.
