Borescope cavity inspection in Farnham

A borescope inspection pushes a small camera through a hole about the size of a pencil into the cavity to see whether it is empty, partly filled or filled, what the fill is and whether there is debris.

Every elevation is judged on its own exposure. Much of Surrey sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
