Estate Waterproofing in Holmby Hills

Holmby Hills estates put an unusual amount of the property on top of something else. Tennis courts, terraces, formal gardens and reflecting pools are frequently built over a lower floor or over a garage, which makes them waterproofed decks with soil, paving or water sitting on them permanently. Planters are the specific detail we get called about most. A raised bed against a house wall is a container of wet soil held off the structure by a membrane and a drainage layer, and when either was skipped the damage shows up inside as a stain on a wall of a room nobody associates with the garden. Wine cellars and screening rooms below grade raise the stakes further, because these are humidity controlled spaces where a small ongoing moisture load is a problem long before anything looks like a leak.
