Have you decided you want a flagstone, limestone or concrete patio for your TEXAS 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 ready mix concrete delivery and pumping contractor in TEXAS .
Steps To Finding The Right Concrete Contractor in TEXAS
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 ready mix concrete delivery and pumping 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 TEXAS .
BEWARE OF CONCRETE CONTRACTOR SCAMS
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 ready mix concrete delivery and pumping in TEXAS . 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 TEXAS . 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 TEXAS .If you get even 1 red flag, get another contractor. There are enough guys out there that do know what they’re doing.
Ready Mix Concrete Pumping
Sturdy, durable and economical, concrete is one of the most frequently used construction materials in the United States. Called pourable stone, it was once used by the Egyptians to build structures that still stand more than 3,600 years later. The standard concrete used by most Minneapolis general contractors combines sand, gravel and water with Portland cement.
Different Concretes and Their Uses
Many different varieties of concrete exist and a Minneapolis construction company generally chooses a particular variety for its purposes based on its particular compressive strength, a quality expressed in terms of pounds per square inch (psi) and megapascals (MPa). Some of the different types of concrete are:
Regular Concrete - Standard, or regular concrete, comes in a variety of pre-mixed packages that vary in their water-absorption and setting qualities, depending on the specific aggregates used. For the most part, regular concrete mixes offer a compressive strength in the range of 1450 psi (10 MPa) to 5800 psi (40 MPa). As such, it is not recommended for heavy, load-bearing structures. Minneapolis general contractors commonly use regular concrete for basic installations in residential buildings, for lining curbs and for strengthening sidewalks and driveways.
Shotcrete - Also known as Gunite, shotcrete is generally used where formwork is unnecessary, such as when building against rock surfaces or vertical soil. It is also used for rock support, especially while tunneling. In some cases, additives such as fiber reinforcement and accelerators may be added to the mix.
Concrete, in its myriad of forms, has become an indispensable part of our everyday life. All forms of concrete have to undergo the correct hydrating and hardening process to optimize their unique physical and chemical properties. In particular, care should be taken to mix the cement blend thoroughly in order to produce uniform, high-quality concrete. The right Minneapolis general contractor will be able to use a variety of types and styles of concrete to make your construction project the best and most cost-efficient that it can be.
The Use of Formwork in ConstructionBecause it is a fluid, concrete can be pumped to where it is needed. Here, a concrete transport truck is feeding concrete to a concrete pumper, which is pumping it to where a slab is being poured. Pumping concrete into aluminum concrete formwork in Mexico.
A concrete pump is a machine used for transferring liquid concrete by pumping. There are two types of concrete pumps.
The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labour saving nature of the placing boom. They are a revolutionary alternative to line-concrete pumps.
The second main type of concrete pump is either mounted on a truck or placed on a trailer, and it is commonly referred to as a line pump or trailer-mounted concrete pump. This pump requires steel or flexible concrete placing hoses to be manually attached to the outlet of the machine. Those hoses are linked together and lead to wherever the concrete needs to be placed. Line pumps normally pump concrete at lower volumes than boom pumps and are used for smaller volume concrete placing applications such as swimming pools, sidewalks, and single family home concrete slabs and most ground slabs.
There are also skid mounted and rail mounted concrete pumps, but these are uncommon and only used on specialized jobsites such as mines and tunnels.
Until the early 20th century, concrete was mixed on the job site and transported from the cement mixer to the formwork, either in wheelbarrows or in buckets lifted by cranes. This required a lot of time and labor. In 1927, the German engineers Max Giese and Fritz Hull came upon the idea of pumping concrete through pipes. They pumped concrete to a height of 38 meters (125 ft) and a distance of 120 meters (130 yd). Shortly after, a concrete pump was patented in Holland in 1932 by Jacob Cornelius Kweimn (Jacobus Cornelius Kooijman). This patent incorporated the developer's previous German patent.
Concrete pump designers face many challenges because concrete is heavy, viscous, abrasive, contains pieces of hard rock, and solidifies if not kept moving.Play media Operating principle of piston pump with seat valves
Usually, piston pumps are used, because they can produce hundreds of atmospheres of pressure. Such piston-style pumps can push cylinders of heterogenous concrete mixes (aggregate + cement).
The pump below uses a transfer tube valve, and the one on the right uses seat valves.
