Laid Bricks or Precast – Which is Best?

Precast Concrete WallingWhich is the better option for a perimeter wall?

There are differences between the two that you need to consider when making your choice.  Laid Bricks, or Precast?

Traditional bricks walls are made of clay, and though sturdy, it has a tendency to crumble when pushed upon continuously.

Each brick must be laid individually, so takes a long time to build, and a lot of labour.

Bricks are also subject to moisture damage, and therefore not a really suitable option for retaining walls, especially in moist climates.

The upkeep on a brick wall can, over a period of time, be financially draining.

Precast walls, on the other hand, are far more durable, and resistant to mould, fire, termites, and other natural hazards.

Very little maintenance is needed to keep them looking aesthetically pleasing as well as strong and durable.
They are quick to put up, so therefore are the cost effective option.

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)

Plastering my Boundary Wall

plastering walls2

Pre cast walls are extremely popular and hundreds of thousands of homes, businesses, government institutions and departments have made use of its applications. There is however a limiting factor in terms of the look and designs available to the consumers of the product. The patterns and designs that are available, very rarely compliment the appearance of a persons’ home. Over time, precast walls can also become dirty and unsightly. These were the motivating factors that caused us to research ways and means to alter the aesthetic value of a precast wall. We have replicated many of the traditional expensive looking designs that are associated with plastered brick walls, as well as developed new designs that can all be easily and inexpensively applied to precast walls. Our market research indicates that the costs of installing a new precast wall and plastering it, are half of that of having a brick wall built. The inconvenience associated with building a brick wall is virtually eliminated.

Up until recently, pre-cast walls could not be plastered in a sustainable way. The conventional methods and plaster mixes used to plaster built brick walls simply do not work on the smooth face of pre cast walls.

The plaster often cracks and delaminates after a short time.

You need a bonding agent specifically designed to eliminate the problems associated with plastering the smooth surface of a precast wall.
Use an industrial strength bonding formula that has been specifically designed as a latex admixture for bonding plaster pre cast walls.  The addition of this revolutionary bonding formula confers numerous advantages over untreated mortars and concretes, such as:

•    greatly improved adhesion to substrates, including dense impervious concrete
•    excellent resistance to water and water vapour
•    improved toughness and flexibility
•    better resistance to frost
•    improved resistance to certain chemicals
•    diminishing dusting
