How to Find a Good Patio Contractor

Have you decided you want a flagstone, limestone or concrete patio for your GEORGIA home. Wondering how to get it done and who you should use? Well, I’m going to tell you how. I’m going to give you a step by step process stating the 3 red flags that signal a bad or uneducated [tag] contractor. These 3 things will ensure you get it done the right way, by the right concrete foundation companies contractor in GEORGIA .

Steps To Finding The Right Concrete Contractor in GEORGIA

First step, first things first. Every Stone Installation Needs A Concrete Footing which might also be called a concrete foundation . This is not opinion but fact. If you want it done right and want it to withstand the test of time, this is the way it’s done, no exceptions. A red flag should go up when any contractor is offering bypassing a concrete foundation as a cost saving option. Unfortunately 85% of the concrete foundation companies contractors out there will tell you they can lay the stone right on top of compacted granite or base material. This type of contractor is exactly who you want to avoid. While what they are recommending to you gives the appearance of a patio, it won’t withstand the climate, erosion and soil movement beneath the patio in GEORGIA .

You might get a few crackless years at best, until it begins to fall apart. This method is the most recommended scam or shortcut of trying to lower pricing and still get the job. Notice the price came down because the concrete footing was removed from the job cost. This option of ” no concrete necessary” is most often offered to those with strict financial limitations. The contractors offering this solution don’t care about your patio or home, they just want your money.With no concrete foundation you get a type of patio, but it’s really just a veneer laid on the ground.

How much concrete do i need?

A concrete patio or sidewalk slab or footing should be a minimum of 4 inches thick. This is sometimes reduced to around 3 1/2 inches due to preexisting structural limitations for concrete foundation companies in GEORGIA . If you encounter space limitations, you really do need a good masonry contractor to resolve the issues with other options. this leads us to our next step.

The 2nd step is hire a knowledgeable masonry contractor in GEORGIA . Do a little research before you start getting pricing. Most good masonry contractors will be able to talk concrete chemistry and technology with you. Yes, I said technology. In the last 10 years there have been some really cool advances in concrete additives and mixes. These advances have provided solutions for the problems and limitations of old. A true patio or masonry professional will be able to talk shop with you, it’s his livelihood. A contractor who can’t do this or doesn’t seem comfortable is more than likely a novice at best. This should be the other red flag that goes up. Basically, Concrete slabs and mortar are like a cake mix. Correctly mixing the ingredients and correctly letting the slab or masonry product cure, are the factors that determine a good solid installation. Again, Talk with your contractor and Make sure he’s knowledgeable about the chemistry, additives and curing process of concrete & masonry. If he is this will ensure the likelihood of a great patio. 3rd step and last but definitely not least, Check references, check reviews and ask to see work they’ve done. Really check this stuff out and try to look at at least 1 job they have done. Ask point blank if the previous client is related to the contractor. Any resistance or confusion in this process would be red flag number

3.So, in order from 1 to 3. All masonry installations need a concrete footing. Make sure your patio contractor is knowledgeable about masonry chemistry, additives and enhancing solutions. Check references, reviews and stay away from the dirt cheap deals of a lifetime from any concrete contractor in GEORGIA .If you get even 1 red flag, get another contractor. There are enough guys out there that do know what they’re doing.

What can be done to combat climate change?

Most scientists believe that the earth’s climate is warming, because automobiles and various smokestack industries are pumping more carbon into the atmosphere than the planet’s ecosystem can absorb, potentially leading to the calamities of climate change about which folks have been hearing for many years. Most of the change appears to be in the Arctic and Antarctic, where ice is melting at an alarming rate. For those who don’t believe the earth’s climate is warming, look there!

Fortunately many people, countries and companies throughout the world are trying to reduce carbon emissions. One major way to accomplish this task is to produce “green” cement. Please read further and find out how using green cement could greatly reduce humankind’s “carbon footprint” and perhaps help save the planet in the process.

What Is Cement?

The Romans invented concrete and built their marvelous empire with it, using a mixture of lime, volcanic ash and chunks of stone to construct immense buildings such as the Pantheon and Colosseum. These days, the primary ingredient in concrete is cement, commonly known as Portland cement, which is produced by burning limestone, mostly calcium carbonate and loaded with CO2, to which clay is added, and then water, sand and aggregate to produce concrete, which is inexpensive, pourable and dries as hard as a rock. Concrete is essentially artificial stone.

According to the article “Green Cement” in the December 2011 issue of Smithsonian magazine, in 2010 the world produced about 3.6 billion tons of cement, and that amount could increase by a billion tons before 2050. Interestingly, the only substance the world uses more than concrete, in total volume, is water!

Why Is Cement Dirty?

As useful and cheap as cement is, it has environmental drawbacks. Fossil fuels are used to burn the limestone at 2,600 degrees Fahrenheit, and this process releases large amounts of CO2 into the atmosphere. Cement production accounts for five percent of the world’s human-produced carbon dioxide emissions; only automobiles and smokestack industries used to make electricity and steel release more greenhouse gases in the United States and China, the world’s largest producers of cement.

Per an article entitled “Cement from CO2: A Concrete Cure for Global Warming?” in the August 2008 issue of Scientific American, making a ton of cement results in the emission of roughly one ton of CO2.

What is Green Cement?

The Smithsonian story mentioned above stated that since 2004 companies throughout the world have been trying to make Portland cement more environmentally friendly. Producers have added steel byproducts, such as slag; coal residues, such as fly ash and other materials to try to bulk up concrete, thereby requiring less Portland cement in the mixture. They’ve also used mineral additives, trying to reduce the temperature needed to prepare the materials, thus reducing the CO2 spewed when heating the limestone. Unfortunately, compounding the problem, nobody understands exactly how Portland cement works!

A potential breakthrough came when researchers at a company named Novacem, located in the United Kingdom, began using magnesium oxide instead of limestone to produce the primary ingredient in cement. Magnesium oxide can be prepared for cement by heating it to 1,300 degrees Fahrenheit, half of what is required for limestone. But something else had to be added to the magnesium oxide to make the cement harden, so magnesium silicates have been put in. These carbon-free compounds are made from talc, serpentine, olivine and other minerals, all of which are quite plentiful and found throughout the world. Otherwise, Novacem’s process is kept a secret.

Of some importance, Novacem’s cement is pure white, rather than gray like Portland cement. White cement can be colored, enhancing its possibilities, particularly when used to make houses and office buildings.

Available on the Internet, the company overview for Novacem claims that for every ton of Portland cement replaced by Novacem’s, emissions will be reduced by 850 kilograms. But the jury is still out on whether Novacem’s cement will be as strong as Portland cement. If it isn’t, few construction companies will use it.

Recycling CO2 to Make Green Cement

Calera, a company in California, has an innovative procedure, perhaps the dream of recyclers. It uses CO2 emitted from a power plant and mixes it with seawater to create carbonates used to make cement. These carbonates can be added to Portland cement to replace some or all of the limestone. Using similar technology, the Chinese plan to build a cement plant next to a coal mine in Inner Mongolia, where they hope to use the carbon emissions to produce cement.

More Ideas

Researchers at Louisiana Tech University are doing away with limestone entirely, using instead a paste called geopolymer, which is made of fly ash, sodium hydroxide and potassium hydroxide.

Calix, an Australian company, makes cement by using superheated steam, which modifies the cement particles and make them purer and more chemically reactive. The process also makes it easier to separate the carbon dioxide and keep it from escaping into the atmosphere.


The stakes are high to produce green cement, for cement production is a $170 billion-dollar per year industry. Make it, and many construction companies will come. Naturally the stakes are also very high for the planet to significantly reduce its output of greenhouse gases. It appears the technology is emerging. It will simply take time to find the best “green” cement.

What Does a Concrete Contractor Do?

Geothermal / Radient Heat

Snow and ice covered driveways and walks have been plaguing man for many winters now. we have created tools and machines to assist us in our efforts of snow removal, but they still require bundling up and facing the cold. Would it not be wonderful to watch the snow melt away as it lands on your walk, no matter what the current weather conditions? I think I have formulated a solution to achieve this kind of winter wonderland.

To get started we will be discussing to types of heating systems; geothermal and in floor radiate heat. Then we will combine them as one and use them in a different way then normal, let us begin.

Geothermal Heat pump / Ground Source Heat

A ground source heat is an alternative energy heating and cooling system that uses the natural heat of the earth to heat and cool our homes. The concept is simple, below the frost line the ground maintains a constant 65 degrees F. Water or a water antifreeze mix is circulated in pipes that are buried below the frost line or deeper, they are connected to heat exchanging unit in the home where the heat from the earth that has been transferred to the water is used to warm the home. In some cases the water may be heated by other means ( lp, natural gas, electric)once in reaches the exchanging unit. This is actually an efficient way to heat your home, due to the fact that you are only heating the water from its already warm 65 degrees.

In Floor Radiant Heat

In Floor Radiant heating is a heating system which uses heat conduction to warm the floor then the heat rises and warms the room. Most commonly these systems consists heating and circulating warm water in a closed system of pipes. Similar to our previously discussed ground source heat, water is used as the medium for heat transfer. I believe that a combination of these system has been used before for in home heat, but we are talking about warming our walks to melt snow.

Now on to the system.

Snowless Sidewalk

Now to the topic at hand, there may be a system that does warm the walks and melt the snow as it falls but what I am purposing here is a system that uses little to no additional energy. Combining these to effcient heating systems to create a warm, snow resist, shovel free walkway is easy. Frist we aquire some tubing like that used in the ground source system and that used in the radient floor system and design a system of circulation. Then using the figure below as a guide we will need to bury some of it below the frost line and lay some in the poured concrete of our walks and ways. This will need to be done at the time the walk and driveways are poured or the exsisting will need to be destoyed and replaced, unless you can figure out a way to lay the tubing under your exsisting walkways without damaging it (if you do let us know). I will guess that a 4 to 1 ratio of tubing will be sufficent to accomplish our goal. This means we will bury 4 foot of tubing for every 1 foot in the walkway. We will also need a pump to circulate the water and a few valves for maintenance access and system bleed. I suggest laying the tubing in a zig zag pattern with about 8-10inch gap between lines, see figure for illustration. Now our goal is to keep the walk way surface above freezing which is 32 degrees F, so if the water from the earth is 65 degrees then there should be no need for additional heat. With that in mind the only energy require to run our system is a small amount of electrical for the circulating pump. Any small electrical pump will work just fine. For complete efficiency I suggest a small DC pump and small solar panel kit and battery to run it, this can provide circulation at no additional cost. Now you can sip your coffee while standing in the window watching your neighbors shoveling their walks in the freezeing cold.

This hub it not very detailed or specific and the contents are purely speculative and theoretical. This design has not been proven or tested in anyway. I in no way claim to be an expert in the areas I am about to discuss. I also take no responsibility of damages or expenses cause by the implementation of these ideas. I recommend researching the two heat systems mentioned before attempting to build a system like this. I also recommend professional asssistence in any DIY project.

With all that said I am greatly interested in comments and discussion from expert individuals who have or are willing to experiment with the following idea.

Thanks for reading, I look forward to your comments.
