Living by the ocean is a dream for many, with soothing sea breezes and gorgeous views. But coastal homes are exposed to harsh weather conditions and need the right building materials to protect them.
Building materials in coastal climates must be resistant to corrosion, moisture and rot. To avoid these problems, SAGA Construction chose the following durable building materials for a recent multifamily build in coastal Zone VE.
Concrete
Living on the coast is a dream for many homeowners, but it comes with its own set of challenges. You need a home that can withstand the harsh elements of coastal climates, including corrosion, moisture and rot. Choosing the right materials for your modern beach house can help ensure that it can hold up against these forces and continue to look its best over time.
Concrete is a very strong material that can be reinforced to make it even stronger. This can be achieved by using steel rods, wires or mesh that are embedded in the concrete before it sets. The combination of the steel and concrete creates a very hard material that can resist both compression and tension stresses.
The biggest problem with building in a coastal area is metal corrosion caused by the salty air. This corrosion can erode the reinforcement of a structure and cause it to break down. This can lead to structural failure and serious safety risks.
To prevent the corrosion of steel in concrete structures, it is important to use high-quality vapor barriers. These vapor barriers should have low permeance ratings to effectively block moisture. It is also a good idea to inspect these barriers regularly to ensure that they are not damaged or deteriorating. In addition, concrete should be made impermeable to minimize moisture penetration.
Brick or stone
A brick and stone exterior can add a touch of luxury and charm to any home. Known for their durability, these materials provide strong protection against storms and are easy to maintain. Brick and stone are also highly energy-efficient, retaining heat during the winter and trapping cold air in the summer. They are also long-lasting, with many buildings built using these materials standing for centuries, and often millennia, after being constructed.
Brick is a common building material and is available in a wide range of colors and textures. It can be used to create a variety of styles, from traditional to modern. It is also more affordable than concrete block. However, it has less resistance to strain and torsion loads which can make it more susceptible to seismic damage. It is important to choose a brick that meets your local building requirements.
Compared to brick, stone is a more expensive building material. It is a nonrenewable resource, but it does not require as much energy to produce as brick. It is also less prone to moisture, and it can be found locally, which reduces transport costs. It is also possible to use manufactured stone, which is a more durable material that is virtually indistinguishable from natural stone.
While brick and stone are a great option for coastal climates, it is crucial to choose the right materials for the specific site. Coastal areas are exposed to salty sea air, humidity, and strong winds. Low-mass construction is preferable, particularly in tropical climates with diurnal ranges of 6degC or less.
Fiberglass or non-cellular PVC plastic
PVC is a synthetic polymer which is a long chain of molecules. It can be molded into many shapes and forms. It is a great substitute for other materials in building and construction, including wood and metal. It is also very durable and weather resistant. It is a popular choice for siding on buildings, fences, and decking. It is also used for piping and electrical cable insulation.
Both fiberglass and non-cellular PVC plastic are great choices for coastal climates because they are impervious to water, humidity, and wind. They are also easy to work with and can be painted to match any trim or color scheme. In addition, they are fire resistant and resist impacts without gouging or denting. This makes them a good option for homes in coastal areas, as well as for businesses and commercial buildings.
The difference between fiberglass and non-cellular PVC plastic is the type of resin that is used to bind the fibers together. Fiberglass is made up of a mix of natural raw materials, such as silica sand and limestone, and manufactured chemicals. These are combined to create a composite material which is lightweight, strong, and durable. It is then bound with a resin, such as polyester or vinylester.
Expanded PVC foam board is a great choice for signage, store displays, screen printing, stage prop design, cabinetry, and wood replacement projects. It can be painted with standard latex or urethane paints, though lacquers may not adhere to the surface as well.
Timber
Timber is a valued natural resource that serves several purposes: it is used for construction, paper manufacturing, specialty wood products and as a fuel source. Additionally, it offers a variety of aesthetic qualities that are desirable to many homeowners.
In coastal areas, timber is used in the form of groynes and revetments for protection from erosion. These structures must be able to withstand both high mechanical loads and attack from a diverse range of biological organisms. The most common species of timber used for marine applications include Douglas fir, Southern pine and oak. These materials are normally subjected to some form of preservative treatment to ensure longevity in the harsh marine environment.
The durability of timber in marine applications depends on the ability of the material to withstand decay caused by fungi and attacks from insects and marine borers. Preservative treatments typically contain biocides that have been approved by the European Union under the Biocidal Products Regulation and a combination of fungicides and anti-biofouling agents.
For a more environmentally friendly choice, timber can be combined with galvanised steel to provide corrosion protection without the need for additional chemicals. This is called cross-laminated timber (CLT) and it has recently gained a lot of popularity in the United States, as well as in Europe. In CLT, timber strands are arranged across the building structure and bonded together using a special adhesive.
