When moisture permeates concrete slabs or walls below grade, how can this problem be solved and does it require excavation?


Selected Answers

From CARLOS CARVALHO of Federal Institute of Sergipe/Brazil on July 21, 2019:
Initially, evaluate the technical and economic feasibility of inserting a drainage system by tiling the walls and floor slabs to avoid contact with the rising or descending humidity. After this step, inject grout (cement) under pressure into the slab or wall to fill the network of interconnected pores.
