Water at the walls: drainage items in Deanside resales
Ground falls, soil against cladding and weep holes, and why they matter on clay.
In short: Most problems at the base of a wall start with water going the wrong way.
Ground falling in
Ground should fall away from the house. Where it slopes back, water collects at the footings and the clay swells.
Cladding clearance
Cladding needs at least 150mm clearance to the ground to keep moisture and termites out.
Drainage slots in the brickwork
Weep holes are how water in the brick cavity finds its way out. Buried or low weep holes trap moisture.
Sealant and tiles
Failed sealant and cracked tiles in wet areas let water into walls and floors.
