Reservoir Claddings and Mass Walls

Guest: Sarah Gray, P. Eng., RDH Building Science Inc. Reservoir claddings include brick, stone, terra cotta, and even stucco, that are all porous materials. When exposed to rain or vapor diffusion, those pores will absorb and hold water until, the pores dry out. Just like a dam holds back lake water, the damned bricks hold the rain.
