How does the salt from the ocean affect your home?

The salt from the ocean doesn’t only affect your home during the warm summer months. Your home is susceptible year-round as ‘sea-spray’ can occur at any time. This is when water from the ocean is lifted up by the wind, and the salt in the water doesn’t dissolve so it is carried and eventually settles on any and all structures, including your home.

Does soaking wood in water make it stronger?

Evidently increasing the water content of wood by soaking wood samples in this way lowers the stiffness and strength of the wood. When dry timber has its water content increased to the levels found in green timber, the cell walls fill with water. This causes the cell walls to expand and a dimensional change occurs.

Why does wood decay?

Wood mostly decays due to the action of decomposing organisms— the worst offenders are wood boring worms. Obviously, an animal eating a hole through the hull of your boat is bad. So, if you can keep these organisms from getting at the wood, that will keep the wood in good shape. The remainder of the decay happens through oxidation, which is chemically similar to iron rusting. Again, this isn’t due to the water itself, but to oxygen and electrolytes (salt, etc) present in the water.

What happens if you take oxygen out of water?

So, if you can take most of the oxygen out of the water, you have no pests, AND no oxidation. Peat bogs are a great example of this. Semi-stagnant water, so there’s no movement and no fresh oxygen coming in, is filled with plant matter. This decays, and the decay uses up all the oxygen in the water.

How long does plant matter last in a bog?

Does saltwater preserve wood?

Re: Does Saltwater preserve wood?#N#Yes, as Philster said, salt is a preservative. There is also a fairly narrow range of moisture content in which the fungus that causes 'rot' can live in. One of the reasons that timber can be 'salvaged' from lake bottoms is that it is in an anoxic environment (no oxygen). The organisms that cause the daecay can't live there.#N#As far as salt being a preservative, Charles W. Morgan (1841 whaling ship) at Mystic Seaport is currently undergoing a major rebuild and during the replanking of her bottom they are actually filling the voids between her planking and ceiling with a salt mixture to help perserve her. - Up to this rebuild something like 80% of her below-the-waterline structure was original. Now that's amazing!#N#Regarding Constitution, she has been re-topped, rebuilt, and restored so many times that... "The Naval History and Heritage Command Detachment Boston, the unit charged with overseeing Constitution’s maintenance and repair, estimates that 10 to 15 percent of the ship’s fabric is composed of timber installed between 1795 and 1797. This “original” wood includes the ship’s keel, lower futtocks, and the deadwood at the stem and stern."

How does saltwater affect timber?

Saltwater does also have the tendency to damage wood that is in its constant, direct contact, specifically boat docks and decks overhanging the water. The wood wicks saltwater into the structure, and similarly once dried, salt crystals form in the timber cells and push the fibres apart. Despite the damage to the outer layers, timber houses, decks and docks can still be structurally sound for over 30 years, as the inner layers of the timber retain their strength. Timber that is constantly exposed to damp conditions, or is alternately wet and dry over a long period of time, can fall victim to several forms of fungal decay. However, in this case, salt is on our side! Fungi is unable to grow in salty conditions.
