What is With All the Noise Pollution?

Do you live in a noisy neighborhood? Concrete fences could be your solution to peace and quiet..

Country Wide Walling concrete precast palisade fencing and retaining wall in the east rand. 3It is about time to turn down the volume! Noise pollution has been a major concern of health deterioration due to restlessness and sleeplessness. We should not have to compromise our quality of life to bear with our noisy neighbors. Whether you live near a school zone, construction site, high traffic area, or any areas with excessive noise, precast concrete walls are the most effective methods of cutting down the noise! By reading this article you will understand what you can do to reduce the level of intrusive noise entering your home.

To begin, let’s understand the nature of sound waves. Sound waves are very similar to water, as it would bounce off objects and flow through holes. For instance, sound waves from cars zipping pass your home would bounce off your drive way and flow through the window that you have opened in your living room. However, unlike water, sound waves can also pass through objects that are thin and uncompressed. This means, even if you had closed your window, sound waves, that are strong enough, could also pass through your drywalls and enter your home without an invitation! We recommend using dense objects materials such as concrete to absorb or reflect sound from entering your home. Another rule to remember how sound waves travel is the “line of sight”. If the source creating the sound is in your sight, then you’ll be able to hear it! This means if you live on a hill, you may want to build a taller wall!

An important factor to look at is sound wave intensity, which is measured in decibels. The loudness of sound generally doubles when sound is increased by 10 dB. According to Harvard Medical School Health Letter, studies have shown prolonged exposure to 85 or more decibels can cause permanent hearing loss. More importantly, physiological damage can also occur at lower levels! The following chart illustrates the intensity of sound at factors of 10 dB:

0 – 1 dB
Faintest sound that can be heard
30 dB
Quiet conversation, soft whisper, quiet suburb
40 dB
Many computer hard drives range an average of 40-50 dB, soft whisper [five feet]
50 dB
Light traffic at a distance of 100 feet
60 dB
Conversation at one meter, or average street traffic at 100 feet
70 dB
TV, noisy restaurant [constant exposure], busy traffic [at one meter]
80 dB
Heavy city traffic [25-50 feet], alarm clock at two feet
90 dB
Pneumatic drill [or hammer] at one meter
130 dB
Sound vibrations felt, thunder or near a four-engine jet at thirty meters
140 dB
Gunshot blast, or jet plane take-off at close range [approximately 200 feet]

Chart: Correlations of dB levels to causality of noise.

In Canada and the United States, the maximum permitted noise exposures level for 8 hours are within 80 dB to 90 dB depending on which province or state you live in. At 80 dB, heavy city traffic is one of the most pervasive unwanted noises transmitted to residential homes! When noise pollution hit your front lawn, precast concrete fences may be an ideal solution for noise abatement to your ears.

According to National Precast Concrete Association, “concrete’s greater mass reduces sound penetrating through a wall by more than 80% compared with wood or steel frame construction”. With this being said, precast concrete walls will surely provide you the peace and quiet that you’ve been aching for. Finally, before you head out to build your precast concrete wall you may want to consider the following points:

* Understand where most intrusive noise are coming from

* Decide on the level of decibels reduction you want your sound barriers to have (not all walls provide equal noise reduction)

* Understand the maximum permissible height that you can build your sound barrier (ranges differently in each province/state, check with your municipality)

* Determine the thickness of your sound barrier (thickness usually equates with price)

* Determine the design your sound barrier (some precast concrete fences have holes, which would not be ideal in reducing noise level)

Cleaning Precast Retaining Walls

addingcolourOur retaining precast walls can have permanent colour added to the wet concrete during the manufacturing process, which will ensure that future painting will be unnecessary.   You do have the option to have the fences stained or painted at a later date as a design feature.

If your fence is looking dirty or drab, you can clean the fence to make it look new again.   Over time dust and dirt can build up on the fences, and will need to be cleaned.

Even though precast retaining walls are made to withstand the elements, it does not mean that over time they will not begin to show wear, especially if not sealed properly.   Mould and mildew can grow over time, as unsealed walls absorb moisture.

PowerWashingA good foam cleaner can be applied to the walls and left to dig deep into the surface.   A power washer will do a really good job of cleaning the wall.   We recommend a sealer is applied once the wall is properly dry to prevent any further moisture stains on the walls.   

Our walls are sealed as part of the manufacturing process to keep them looking good for many years, but scratches and chips can cause moisture to seep in.

We recommend repair, or replacement of any sections damaged, as this will prevent deterioration of the walls.  Sealing the walls properly is a high priority to extend the life of the walls.

As our walls interlock, we can replace any damaged sections and ensure you have the best looking walls for many years.

No Place to Hide

green palisadeWhether you choose palisade or solid walls, your main concern is security for your property, family and belongings.

There are many options for security walling, and a lot to take into account when choosing what is best for you.

Not only do you want security, aesthetic appeal is also a must, as it enhances not only the look of the property, but also the value.

treesShould you choose palisade fencing, there are also options available to you. Palisade fencing comes in concrete, or steel.   Palisade is a great off-putter to would be intruders, as it offers no privacy or hiding places for them once they enter your property, but it is also not as private for you as a solid wall would be.

The fact that it offers no cover for intruders is a good reason to use palisade, as intruders can easily be seen from the road

You should always use either a low brick fence as base, or a concrete apron on which to build your palisade, as you do not want intruders being able to dig under the fence to gain entry. Make sure you have a good foundation, so that it is too difficult to dig under to gain access to your property.

Palisade can also be used as a topping on brick or concrete walls.  This will prevent children or animals from slipping out of your property and getting into the traffic, as well as being off-putting to would be intruders.

Always make sure that you do not have trees growing close to your boundary walls, as this is an easy way for intruders to gain entry.

Wall Maintenance

big treeAs walls are our security, it is a good idea to check them regularly for any damage.   Planting big trees too close to a wall can cause damage as the tree grows and the roots expand.   It is never a good idea to have big trees close to a property, thus circumventing the security your wall offers you.

Check regularly that nobody has tried to chip away at your wall to gain access and immediately have it repaired if you discover any damage.  Country Wide Walling incorporates steel reinforced modular components that interlock during the installation process, thus making them very strong and durable.

Permanent colour can be added during the manufacturing process which eliminates future painting of the walls, rendering exterior wallthem aesthetically pleasing for many years.

If you chose to paint your wall after installation, you need to check and repaint your walls when necessary to avoid them looking drab and dull and spoiling the look and feel of your property.

A good quality wall is both aesthetically pleasing and adds value to your property.   It also provides security and privacy.  Country Wide Walling manufacture and install many different types of wall, so you can choose what would best suit your needs.

Common Problems with Painting Concrete Walls

Painting concrete walls can result in a few problems if the concrete wall has not cured. If the concrete cannot adequately cure before it is painted, the paint will trap the excess moisture within the concrete and the paint can peel some of the cement as it peels itself. Painting the concrete wall can also cause the plaster to not receive the water cure that it needs.

common problems

Cracks in the Wall

Before priming the wall, cracks in the concrete should be filled with a material that can withstand weather effects. If the wall plaster has a texture, then sealant should be of a matching texture. If it is not, bands of smooth surface can be seen through every coat of paint in a different contrast.

Coverage

If primer and paint is applied, it needs to be applied across the whole surface in order to have the best results. Once the primer has been applied and allowed to cure, the finish coat needs to be laid on in several thick coats. If not, the uniform color will not be attained and you will not achieve the look that is desired. Some projects do not have primer applied before the paint. Other projects may have had paint thinned so much that the coat is not even effective. This makes the wall look like it did not receive adequate coating.

Primer

In order to get the bond desired, the right primer will need to be applied to new concrete walls. This will prevent paint delamination also. There are some paints and primers in particular that needwall painting to be used together. Although cement plaster and concrete should have a coat of primer before the paint is applied, painters do not always prime concrete and plaster.

Delamination

Delamination is the process of paint peeling from a new concrete surface or cement plaster. Paint will delaminate from concrete just as it does from wood and metal. This is why the concrete wall needs to be well prepared and all application procedures need to be followed. Moisture from rain or from the concrete not curing will release from the concrete and cause cleaving.

Over Brushing the Paint

If a painter applies paint to the brown coat on cement plaster, the paint will serve as a bond breaker causing delamination. Plaster behind a coat of paint will turn soft if paint is not allowed to cure. Paint will keep the water from evaporating properly. Concrete walls need to be prepped and primed. Paint needs to be thick and not diluted.
