Rising Damp Smith (Don Warrington) is a planning student who claims to be the son of an African Chief. As a black man, he brings out the ill-informed fears and knee-jerk suspicions of Rigsby. However, the landlord quickly accepts his new tenant and henceforth regards him with a wary respect... wary because of Philip's intelligence and smooth manners, and especially because Miss Jones finds herself attracted to the handsome sophisticate. Of these four principal actors, only Beckinsale was a new recruit - the others had all played their roles in the original stage play. In the first series, there was another tenant
Damp (structural) D Hoff in their paper "Rising damp: capillary rise dynamics in walls". The analysis is based on experimentally well established properties of porous building materials and the physics of evaporation from building surfaces. Hall and Hoff show that the model can be used to predict the height to which damp will rise in a wall. The height of rise depends on the wall thickness, the sorptivity of the wall structure and the rate of evaporation. Further work has confirmed experimentally the importance of mortar properties in determining the height to which damp will rise in walls. "BRE Digest" 245 lists
