Important Considerations for Building in Coastal Environments
Building in a coastal environment can have its challenges, but with the proper preparation and the right builder, it’s all a matter of careful planning.
The experts a Pivot Homes have shared the most important design considerations when building a coastal home:
Take Appropriate Steps for Corrosion Protection
Unfortunately, no building material offers 100% corrosion protection. But there are extra steps that you can take to protect your home properly, starting with the right grade of steel.
The most common grade of stainless steel, 304, chrome-plated or coated steel is generally used on normal house fixtures. However, seawater and salt air can get under the coating and cause corrosion. This will dramatically impact both the lifespan and the functional properties of the steel.
Instead, coastal homes should use 316-grade stainless steel, which has an alloy addition of molybdenum that makes it “marine grade”.
Even the finish of stainless steel impacts its lifespan by the sea. Brushed or matt finish stainless will rust quicker than polished stainless steel as the polishing seals the pores of the metal and stops salt deposits from building up.
Mitigate Water Damage with Proper Cladding, Paint, and Roofing
Choosing the proper materials for cladding, paint, and roofing could greatly aid in protecting your home. For ultimate protection, consider opting for Colorbond Ultra Steel or Stainless Steel products for the roof, walls, downpipes, fascia, and gutters.
If you prefer the natural look of timber, you may incorporate timber-looking composite products that are heat and water-resistant. They are also a lot easier to maintain in the long run compared to natural wood.
Paint serves as another layer of protection for the steel and/or timber. In a severe marine environment, regular cleaning and even annual recoating may be required to maintain the top performance of the materials. To ensure a long-lasting result, be sure to have the exterior thoroughly cleaned first and use a suitable primer to prepare the surface.
