Core Drilling Brisbane

DIY vs Hiring a Concrete Cutting Service – including a Step by Step Guide

There is a vast variety of concrete saws and equipment that can be hired to do that pesky DIY project that you have always wanted to get done. But when should you hire a professional and when should you just give it a crack? To do your concrete cutting or core drilling job properly and on budget you will need: the right equipment, the right type – wet or dry, the right protection for yourself and the environment, the right skills and the right value for money. There is lots to consider, but if you read on and follow this step by step guide we can explore this in a little more detail.

Step 1.Choose the right equipment: For gener slab cutting Brisbane you will need a Floor Saw or Kwik Cut Saw (Hand Saw). This process is used when reasonably level and flat surfaces have to be cut and includes cutting through reinforced concrete, precast concrete, and other structural materials.

These surfaces include floors, roofs, bridge decks and suspended slabs. The surfaces are usually cut to provide expansion joints, to make openings for ducts, elevators, stairwells, machine pads, trenching and for demolition purposes.

For wall sawing Brisbane you will need a Kwik Cut Saw (Hand Saw) or Ring Saw. This process is used for the cutting of openings in vertical surfaces and surfaces with slopes so great that floor saws cannot be used.

These surfaces are usually cut to provide for doors, windows, vaults, silos, chests, foundations, ducts or large diameter pipes, or to remove part or all of existing walls. For core drilling Brisbane through a floor or wall you will need a core drill. Core drills can usually drill holes from 25mm dia – 660mm dia. This process is used for the drilling of circular holes in reinforced concrete, precast concrete, asphalt, brick, cinderblock and other structural materials. Usually the holes are made for electrical, plumbing, heating, sewer and sprinkler installations. Other applications include holes to anchor bolts or lifting rods, to place explosive charges, to install load carrying devices, or for analysis of the structure of the rock.

Step 2. Wet or Dry cutting? I don’t mean to scare you here, but cutting concrete can be very messy. You can probably figure out that the dry cutting means cutting without water and should be less messy… hmm not so sure. Cutting without water means dust and lots of it. Very messy, minute particles of concrete will billow into a thick cloud of grey concrete dust or red brick dust and coat everything nearby you own. Personally I prefer the wet cutting machines. Even though the mess is wet grey or red slurry, it is much easier to clean up all the mess with a wetvac (wet and dry vacuum cleaner) and a wipe over with a damp cloth. Dust on the other hand can get absolutely everywhere.

Step 3. Protect yourself and the environment. Basic safety equipment you will need include goggles, ear plugs, safety boots/steel capped gumboots and gloves. If you have chosen a dry cutting machine you will also need to work with a dust mask on to protect your lungs, and sun protection and long sleeves if you are working outside.

Cutting concrete can be very noisy so be mindful of neighbors and nearby businesses in case of noise pollution and air pollution. Think about what is below you if you are cutting on a floor higher than ground floor. Sadly I have heard of some terrible injuries because of falling cores and no safety barriers. Protect the environment with plastic sheeting, extraction fans and a wet/dry vacuum cleaner. In many countries, letting waste such as concrete slurry go down the drain is against the law and you will be fined.

Step 4. Check if you have the right skills. There are many dangers associated with concrete cutting equipment. Even though this equipment can be readily hired, this equipment should only be operated by experienced personnel. You won’t need to google ‘saw injuries’ to imagine the dangers of operating such powerful equipment without the right know how and strength.

Step 5. Check out the cost. Believe it or not the cost to hire a skilled professional who has all the equipment needed and can get the job done with minimal fuss, is often not much more than hiring the equipment yourself. Aside from the safety risk, mistakes in concrete are expensive if you get it wrong. Before you go ahead with the hire, at least get an idea of price from a professional by obtaining a quote.

For example you may be surprised to know that at elliottandfyfe.com.au you can hire a Brisbane concrete cutting operator to do a basic job for about $150.00. That’s hardly more than the cost of hiring the concrete cutting equipment, and comes with a skilled operator to do the hard work. Might just be worth the call?

Shrink Wrap Film – Presentsation Counts

Manufacturers across the divide continue to produce quality products. We are all too familiar, with the attractive transparent packaging of toys, imported fruits, clothes, pens amongst other things. Unlike the previous times, customers can still have a glimpse into their prospective purchases, carefully examining them without necessarily compromising their state or quality (food).

It is of note that, both polymers are ideal for different packaging purposes. The choice of shrink film is determined by the product, budget and level of technology the producer in question has.

The undeniable fact is, packaging being the cornerstone of branding and advertising can be responsible for high sales volume or the reverse. Manufacturers and producers alike are today faced with the tough task of choosing the ideal packaging material. In the end the functionality of the shrink wrap can only be determined by the manufactures and producers.

It is as a result of these demands that the skrink wrap film was developed. In the formative years; we were all accustomed to the brown paper bags which had our tree population on the decline. Subsequent move to the opaque store-name-christened polythene was a further disservice. Then came the perfect solution to all these problems, the shrink film.Initially, the shrink film was exclusively made from PVC (Polyvinylchloride).This is a plastic polymer (third most used plastic in the world) that had the capability of sealing products with a thin layer of plastic sheet. These sheets were often transparent to allow the customer have a view of the product.

The sheet would be wrapped over the product and passed over a heat tunnel or a heat gun. Normally, the length or circumference of the product would be measured, 10% of this value would be added then the sum is divided by two, this would give the size of PVC shrink wrapping to be used. PVC has the ability to shrink by 40% percent giving the packaging a tight grip of the product.

However, with time it was noticed that PVC could release small amounts of hydrogen chloride giving the products a characteristic smell in addition to poisoning. The sealers also would have small carbon deposits. The presence of a plasticizer in PVC had the drawback of hardening and shrinkage during cold weather and extreme stetching with subsequent temperature increases.

These drawbacks meant a suitable shrink film devoid of a plasticizer be developed. Polyolefin was found to have the packaging abilities of PVC but lacked the setbacks that faced the latter. It became a preferred choice of packaging. Offering a stronger seal and fewer odours. Its lack of plasticizer meant no physical changes to the shrink film. It would become the perfect storage solution; all weather .Lack of chlorine in its polymer meant no hydrogen chloride previously characteristic of PVC. Visit http://www.redblade.com.au/shrink-wrap-plastic-films.html for info about film options.

However, while its predecessor PVC enjoys machine compatibility and low cost purchases, polyolefin is the opposite, it remains relatively expensive and hard to use alongside machines.PVC on the other hand remains a suitable choice for manufacturers who don’t deal with edible products. Owing to its cheap price and machine compatibility it is a manufacturers darling.

The benefits of a steel rainwater tank

Queenslandwide steel rainwater tanks are an increasingly common sight across the Australian suburban landscape, and for good reason. We live in a hot, dry country where every drop counts, and many homeowners are eager to protect the earth’s precious resources and save money at the same time. While earlier models tended to be bulky and unattractive, the latest domestic water tanks are specially designed to fit into awkward spaces and complement modern architecture. Steel is proving to be the correct choice, not only for its stylish looks, but for its durability.

Space is a premium on urban blocks with smaller land sizes. Because of this Queenslandwide’s extensive range of custom-size slimline water tanks are increasingly popular in urban areas of Australia, where space is a real problem. These slimline water tanks have evolved so oval tanks, rectangular tanks and other configurations meet the needs of customers who don’t have the space to fit the traditional round water tanks on their blocks.

The benefits of a steel rainwater tank for your home are considerable and will offer you plenty of return on your investment, and you don’t need to live in a rain forest area or a high rain density area to have one.

Australia is now embracing the water tank phenomenon and at Queenslandwide Tanks, we are here to help you with all you need to know when it comes to rainwater harvesting. When you invest in a Aquaplate water tank, you will be able to collect most of the rain that falls on your roof if you have it connected to your gutters and downpipes. For example, if 10mm of rain falls onto about 100m2 of your roof, you will collect about 1000 Litres of rainwater into your water tank. Just imagine, after 4 days of light rain you could easily harvest around 4000 litres of rainwater.

The benefit of rainwater tanks are endless and of course ensures that your home becomes environmentally friendly. You can reduce the amount of water used from the main supply therefore reducing your drain on this precious resource. By reducing the demand on mains water to your home, you will reduce your water bills, and by connecting the rainwater tank to a rainwater pump you will be able to water your gardens, wash your cars and fill your swimming pool whenever you want at no cost.

The other benefits of installing a Slimline rain water tank in your home are the government rebates now available to residents across Australia. And did you know that rainwater is actually less salty than dam supplies therefore it is much healthier for your gardens and appliances like your washing machine as they will actually be better of using rain water. The other benefit of owning rain water tanks means that you will never have to worry about water restrictions around the home for washing your car and watering your garden.

Imagine how easy it would be to wash your car with rainwater whenever you like, and imagine how beautiful your lawn and plants are going to look when you start using rainwater for your garden.

It’s best to use the water in the tank on a regular basis so there is always storage capacity available in the water tank when it rains. By connecting your water tank to a washing machine or toilet, you will get good use of the tanks supply and will allow rainfall to re-fill the rain water tank more often. By using the water tank this way you will maximize the amount of rainwater you will harvest and the money you will save.

Reflections on Life

Life – what is life! Life can be described in many ways and has many facets and interpretations. It presents us with an ongoing stream of experiences of situations, events and interactions of all kinds with other people and our environment.

It is creation in its magnificent splendour – the original bringing into existence of the universe by God.

For humans it is a journey encompassing all the seasons, colour and streams of life’s experiences.

The miracle of new life in any form of creation brings wonder and amazement as we become aware of the intrinsic formation of such an unexplainable divine plan.

For humans there are many rituals and traditions that help celebrate the different seasons and significant moments in life.

A welcoming of a new child might entail a ritual of a Christening or Blessing in the Christian tradition or perhaps a Naming Ceremony for those less religious. In other cultures and belief systems children are welcomed in a variety of ways but none-the-less mostly it is found to be a joyful celebration of the miracle of new birth.

Life can sometimes be brief – the miracle taken back from where it began just as life is beginning – the mystery of why these sad experiences happen not to be explained.

Life changes for humans as the body grows and life is experienced in new ways. Learning takes place as the brain develops and intelligence is gained and used for the betterment of human kind.

At times the human body suffers from physical limitations this being a challenge as strength of spirit and courage come to the fore.

During the seasons of life ritual is shown to be important such as times of celebration when a person reaches the age of eighteen – a time of maturity and starting out as an adult on life’s journey.

Permanency of relationships can be celebrated by the ritual of Marriage as people start a new chapter along the journey called life.

The miracle of new life can emerge again in this relationship of Marriage as a new life is created and welcomed to the world.

As the continuing seasons and cycles of life are observed, life can represent colour as of a rainbow in these seasons of new beginnings, celebrations, changes and endings.

Red, orange, yellow, green, blue, indigo and violet – colours of the rainbow – how symbolic of life’s journey as the rainbow is composed of the entire spectrum of colour from the shortest wavelength violet to the longest wavelength red.

A closing ritual now takes place as the body has accomplished its purpose and the ending of life as humans know it is honoured and the life celebrated as the spirit travels back to the Divine from whence it came.

Styrofoam: History, Properties and Building Applications

Styrofoam is a brand name for Polystyrene Thermal Insulation material (sometimes referred to as “extruded polystyrene foam”). It is a trademark of Dow Chemical and among the most popular plastics in use today. Styrofoam is manufactured in blue sheet foam. It is mostly used in building materials and pipe insulation. It was invented in during World War II by Ray McIntire as he sought to create a flexible electrical insulator. It is usually supplied to manufacturers in form of small foam beads. It can be molded and processed to fit different purposes. The word Styrofoam is inappropriately used in Canada and the United States to refer to expanded polystyrene foam such as cushioning material in packaging, coolers, and disposable coffee cups. These are made of expanded polystyrene beads, and not from the extruded polystyrene normally used in Styrofoam insulation. There is also a different form of Styrofoam used in craft applications which is green and white in color.

The Properties of Styrofoam

Chemical Representation
Styrofoam’s chemical representation comprises of a hydrocarbon chain linked with a phenol group to every single carbon group. Styrofoam’s chemical equation has a (Ph) with a C6H5 ring.

Polystyrene
Polystyrene’s density is 1050kg/m3 as compared to water which has a density of 1000kg/m3. Although it is denser than water, polystyrene floats and doesn’t sink. It can break down when combined with a strong acid.

Polymer and Thermoplastic
A polymer is a Styrofoam molecule. It is an extensive chain of recurring atoms through the connection of many molecules (monomers) derived from petroleum. Styrofoam is also a thermoplastic as it hardens when cooled and softens when heated. As a liquid, it can be easily molded which makes it suitable for various applications in different industries.

Shock Absorber and Lightweight
Styrofoam is an excellent shock absorber and extremely lightweight. It is composed of approximately 90 percent air. This is why expanded polystyrene is very popular as a cushioning material. Styrofoam is easy to transport as its shock-absorbing features keep it well protected from harm.

Insulator
It is a superb insulator that limits thermal transfer. This major aspect makes it a top insulating material as it effectively maintains a comfortable temperature indoors, regardless of the weather conditions outdoors.

The Uses of Styrofoam in Buildings

Insulation
Styrofoam is used by many builders as an insulating material. It has a closed cell structure which ensures its insulation has a high R-value (a material’s ability to conduct heat). The more value a material has, the more resistance it has to conducting heat. When a building is properly insulated, heat is not transferred out of a building or into it which reduces drafts and decreases cooling and heating costs. Styrofoam is used to insulate basement walls, underground walls, and above ground walls as it significantly reduces energy loss. It is cut into sheets that are attached to a building’s frame or installed in its outer foundation walls. The foam is afterwards covered with certain material to create a specific look, such as marble, stone, or stucco. Styrofoam is also used in insulating floors and roofs. On roofs, it is cut and positioned to provide the proper drainage. Plywood or other materials are placed over Styrofoam after it has been laid on ceiling material. Afterwards, shingles can be installed on top. Styrofoam is used on floors as it is an excellent load-bearing material for different types of floors. Its closed cell structure makes it very rigid and highly resistant to compression in load-bearing applications. Styrofoam is also used in commercial and industrial piping applications. It is used in low-temperature systems to prevent surface condensation and to minimize heat gain. It retains its main insulating properties in environments with high-moisture conditions, high humidity and in low-temperature applications.

Waterproofing
Styrofoam’s insulation structure leaves virtually no vacant space between the cells which makes it waterproof and strong. It has a natural resistance to water vapor, snow, and rain and retains its primary physical integrity and insulation performance in exposed conditions for a long time. Since the material is resistant to water, mold and mildew cannot grow on its surface.

Hygiene
Styrofoam has a low susceptibility to rot hence fungal and mold growth and reduced. The boards are odorless, clean and unaffected by dust. This ensures that a structure’s integrity is maintained and the occupants stay in a hygienic environment.
