Rainfall

Impacts

• Facade/structure damage
• Leaky buildings
• Rain penetration around openings
• Increased pressure on plumbing/drainage systems

Implicated Areas

• Roof edges
• Open decks
• Walls and joinery
• Retaining walls
• Floors
• Balconies
• Wall/roof junctions
• Roofs

Solutions to improve weather tightness

• Continuous unbroken areas of roofing
• Rainwater collection on exterior
• Install generous overflow areas
• Steeper pitched roofs to shed water quicker
• Low-profile building without high wall in prevailing wind to reduce wind driven rainfall collecting on wall
• Generous eaves/overhangs (600mm+)
• Use monolithic or sheet claddings - more resistant to extreme winds
• Leave outside down pipes unsealed at drain entry points - prevents overflow to storm water drains blocked
• Provide rigid wind barriers behind all claddings
• Install drainage cavities (ie create a gap) behind claddings

Ways to keep the house watertight

• Brickwork- also keeps heat in
• Guttering (well-maintained) - needs to be sufficient otherwise can damage brick/paint work.

Homemade Dome

This is made up of 75 triangles, formed into 5 hexagons, 5 half hexagons, and 6 pentagon panels. All of these shapes combined enabled me create a paper dome shape(ish)
