How Do Construction Materials React to Water?

How Do Construction Materials React to Water?

If you're a homeowner, you've likely experienced the effects of water damage. If you're a builder or contractor, it's likely you've been faced with the challenge of repairing such damage. In either case, it's important to know how different construction materials react when exposed to water. This article will provide a brief overview of how drywall reacts to water as well as general information about how other common building materials are affected when they encounter moisture.

Drywall

Drywall is a material that can be saved if you act quickly. It's made of gypsum plaster, which is porous and absorbs water easily when it's wet. You're probably better off replacing the drywall than trying to save it, but if you have no other option than to try drying out your walls and ceiling, here's what you need to know:

  • Drywall is lightweight and easy to remove. If you don't have special tools or training, removing damaged drywall will be much easier than repairing it. 
  • Drywall is inexpensive and easy to replace.

Wood

Wood, like all plant products, is a hygroscopic material that absorbs water from its environment. When wet, wood swells and expands by almost eight percent. Wood's natural tendency to absorb moisture allows it to shift with changes in temperature and humidity without cracking or breaking as many other construction materials do.

Wood will shrink back to its original size once dry, but this can take quite some time depending on the material of which it is made and how much time has passed since exposure (the amount of time required for drying depends on climate conditions). In some cases, it's possible for wood to be dried out enough for safe reuse before replacement if done carefully; however, there is a chance that too much damage was done during soaking (e.g., rotting) which would not allow for this option.

If replacing large sections of existing structures with new materials isn't feasible due either cost or construction limitations, then having those sections replaced with something else may still be an option; however, there are few other materials available today that have similar durability characteristics like wooden structures do thus making doing so rather difficult at best considering what needs replacing must also remain functional while undergoing replacement work itself!

Plaster

Plaster is a mixture of lime and sand. It is used in walls, ceilings, and fireplaces because it can withstand heat.

Plaster can be damaged by water as well as other chemicals. When this happens, you will see cracks or holes in your walls. To repair these surfaces, you will need to remove any loose plaster that has fallen off and then add more plaster to fill in the gaps. If your repairs require more than just filling cracks with spackle or joint compound (two common types of drywall compound), there are special products called “waterproofers” that can be applied to the surface before painting over them with polyurethane coating like polyurea paint.

Concrete or cement-based materials

Concrete or cement-based materials can be repaired. These materials have a high porosity and absorb water easily, so they will crack and crumble when exposed to water. If the area is too large to replace, you can dry it out then cut out the damaged material, then replace it with new concrete or cement mixture. Another option is to use bonding agents like grout or epoxy that will fill in any cracks in your concrete walls, so they don't grow larger over time.

Steel

Steel is a metal that can be used for plumbing and heating systems, as well as for structural support. A great conductor of heat, steel does not react to water; it expands when it gets hot and contracts when it gets cold.

It is important to know how various building materials react to water if water damage occurs

Drywall is a common building material that is made of gypsum, which absorbs water. This means that when there is a flood or other water damage event, the drywall becomes soft and crumbles. This can be replaced with new drywall before it gets wet again or by using spray foam insulation to create an air gap between the damaged drywall and the frame of your home.

It is important to know how various building materials react to water if water damage occurs. Water can cause serious problems if it enters your home undetected and unchecked. It can lead to mold growth, structural damage, or even fire if not properly addressed right away. If you notice any signs of water damage at all, make sure to call an expert immediately so they can help assess any potential issues before they become too big!
