Concrete Demolition Tools

Demolition contractors have a wide range of concrete demolition tools that can break up large structures quickly and safely. These tools can include sledgehammers and jackhammers as well as hydraulic concrete bursting machines.

Concrete bursting is a near silent technique, perfect for sites where noise and vibration restrictions are in place. It also eliminates the need for a demolition crew to use explosives.

Equipment

Using the right tools and equipment makes all the difference in successful concrete demolition. Contractors have a variety of ‘tools in their tool box’ that they use depending on the site, work environment and available resources.

Concrete cutting equipment includes saws, thermal lance (good for breaking concrete with steel reinforcing) and water-jetting technique which is especially useful on larger structures to cut into more manageable pieces for removal by crane. This method also reduces the amount of noise and dust generated compared to other methods making it ideal for sites where environmental noise and vibration restrictions apply.

When large volumes of concrete are to be removed, explosives can be used. These are inserted into a series of predefined boreholes and then detonated, blasting the concrete into smaller more manageable pieces. This is a very flexible and versatile method but requires a skilled crane operator and it’s important that it is used under strict safety regulations.

Safety

There are a number of ways to break concrete and experienced demolition contractors have a range of techniques in their tool box. They know how to get the job done on time, within budget and safely.

Safety measures include ensuring that a person trained in first aid is available to respond to any accidents. Workmen should also wear suitable protective equipment like hard hats, eye and face protection (with celluloid lenses), hearing protection, gloves and safety boots or shoes.

During concrete demolition, workers should avoid hitting live services such as electricity and water mains. This may require the installation of temporary supports or bracing systems. Other safety measures include regularly checking the structural stability of the structure and implementing protective installations such as debris netting or catch platforms to prevent the risk of falling materials hitting those below. Workers should also hold daily pre-job safety meetings to discuss the risks involved and how to avoid them.

Planning

The demolition of concrete structures can be dangerous work. Laborers can suffer serious injuries and even be killed when these structures collapse during demolition. That is why concrete demolition must be performed by trained professionals.

An engineering survey should be conducted to determine the strength and weakness of the structure before it is demolished. This is important because it can help prevent premature collapse. Any areas that are weakened should be shored or braced before demolition begins. This also helps reduce the chance of damage to adjacent buildings and other structures.

Other hazards of a demolition site include dust, noise and vibration. These risks can be mitigated by proper planning, the use of appropriate personal protective equipment (PPE) and worker training. In addition, a contractor should ensure that all electrical, gas and water lines are disconnected before demolition. This is required by most local governments before a demolition permit can be issued. It is also a good idea to consult with neighbors in advance about the demolition plans.

Environmental Impact

The use of concrete in construction is a significant contributor to climate change, due to the chemical and thermal emissions involved in the production of cement, its main ingredient. This is why it’s important to find innovative solutions and circular business models for concrete decommissioning.

Cement is also one of the main contributors to soil degradation, destroying the most fertile layer of the earth. In addition, concrete causes damage to water and air resources, resulting in surface runoff, pollution, erosion and flooding.

Demolition can produce a lot of dust, noise and smoke, contaminating the surrounding environment with harmful gases. The best solution is to choose a method that’s safe for both workers and the surrounding area. The most common method is to use a crane with a wrecking ball, but this requires a high level of skill and can cause damage to nearby structures. Another option is to use explosives, which must be carefully planned and carried out with the right safety precautions.

What You Need to Know About House Demolition

If a house is in disrepair or doesn’t meet current building codes, it may be time for demolition. This can also be the case after a natural disaster, or for structures that are beyond repair or cost-effective rehab. Before any heavy machinery can start working, there are several prep steps that must be taken. These preparations can include: Get a Permit A demolition permit is a legal document that gives you the authority to demolish a structure. Typically, structures that require a building permit to be built will also need one to be torn down. However, a permit isn’t always necessary. You can get a demolition permit by completing an application and paying a fee. The application form will be available on the website of your city’s Building Department. It will usually include a site plan with the structure that you want to remove clearly marked. You will also need to provide confirmation that public utility companies have stopped servicing the structure. A residential demolition pe...

Commercial Demolition in Hobart

Several factors can increase or decrease your commercial demolition costs. These include landfill waste disposal, permit fees and dumpster rental charges. Also, make sure to consider the legal structure of your business model. The chosen structure can shape tax considerations and personal liability. Reader Rebecca Spry sent in this photo of 10 Murray Street, a former state office building that’s disappearing floor by floor as part of the Salamanca CBD’s Parliament Square redevelopment. Licenses and Permits Demolition companies need to obtain a state or local contractor’s license, as well as insurance to cover workers and equipment. They must also comply with environmental laws, and obtain any specialized certifications necessary for their work. This can include hazardous material handling and operating large machinery. A permit is required for demolition work and may require a grading plan, inspected plumbing permit or cash demolition escrow bond. The type of work will determine th...

How Much Does a Pool Removal Cost in Hobart Cost?

The total pool removal cost depends on a number of factors. These include: the size of your pool, its location in your yard, and any other structures such as decks and enclosures. Draining the pool costs about $175, and the price of backfill materials also varies. Other expenses can include a permit, encroachment permits, and dumpster rental fees. The Size of the Pool Choosing the right pool size will impact how much it costs to install and remove. It also depends on constraints such as property lines, possible zoning issues and the terrain of your backyard. Besides determining the pool’s size, you must also consider its location and whether it has any decking or landscaping. The location will be a factor in how difficult it is for contractors to access the area and how long it takes them to do so. There are two ways to remove a pool: a full removal or a fill-in. A complete removal will cost more as it involves removing the entire structure and filling in the area with dirt. A fi...
