A public park, outdoor restaurant and schools are incomplete without the presence of concrete tables. Those strong and decorative structures meant for rough use throughout the year are known to add volumes to the beauty of the landscape design Sydney while serving the purpose of accommodating picnics, get-togethers or simply youngsters in school at their lunch or play.
What are concrete tables made of?
Concrete tables are made of precast concrete cast into different molds and then finished and polished for a smooth and ready to use surface. The table surfaces are given a quality concrete coating that is able to provide maximum protection against weather and daily use. Most of the tables are designed for outdoor commercial use and have precast table bases and legs which can be easily assembled by the supplier either on site or at his workshop. Long lasting and virtually maintenance free, concrete tables are available in different designs and styles, some even with seating arrangement in the form of concrete benches along with it.
Concrete table designs
Concrete tables come in various shapes and designs. Restaurant style concrete tables with a round or oval table top are very popular. These are also used in schools or picnic areas. Designer concrete tables are also available with separate or attached concrete benches that complement the table design. Some manufacturers have also come up with a designer concrete table that allows wheelchair access or even high chair access on one side. If this is not required, the table can be placed against a wall to create more space. These tables can also be used as an outdoor table for the backyard or patio at home.
Where to locate a concrete table supplier?
Concrete table manufacturers and suppliers are listed in most area directories or yellow pages. Landscape designers and architects would also be great sources of information for such suppliers. The Internet has numerous websites put up by such suppliers and manufacturers. Their websites also give one an idea of how the end product would look like. Although custom designs may not be possible, some suppliers do give a choice of three or four colors to suit customer choices.
Concrete steps are built using concrete mix and a few other simple tools. This can also be an easy do-it-yourself kind of project. Concrete steps are durable and attractive and blend easily with the surrounding landscape. The concrete mix can be purchased from any concrete supplier in ready condition or can be prepared at the site of construction. Concrete steps are constructed with the help of wooden forms.
Important considerations for concrete step construction
The height of the raiser and the depth of the tread are important aspects to be considered before the construction of concrete steps. The step use is the factor that affects the construction parameters. There is a distinct ratio for the raiser and tread measurements, which can be sought from any concrete contractor or reference manual. It is important to keep in mind that the raisers and treads must be uniform in any given flight of stairs.
Concrete step construction
The base is first prepared for laying the concrete steps. The area to be covered with steps is cleared of dirt, stones and any other matter and is dug to a depth of about 6 inches. It is leveled and tamped and the forms are built on this surface. The forms are made of wood which can be easily pulled out once the concrete used becomes dry. The shape and structure of the forms will determine the design of the concrete that is poured into the forms. The surface is screeded and a float or darby used to level the surface area. Edgers and trowels are also used to finish the concrete. The concrete must cure for at least 24 hours before the supporting forms are removed. After the concrete is hard enough for use, it may be decorated according to the homeowner’s wishes.
An alternative to concrete steps
Concrete ramps are an alternative to concrete steps. However they are more beneficial if there is only a slight change in elevation. They can prove to be useful in case wheelbarrows, lawn mowers and other such equipment are used frequently. The only important thing to remember is the slope of the ramp which must meet certain construction specifications.
Concrete pipes have been known to exist for more than a thousand years. Being a long lasting and structurally strong material, a concrete pipe is generally used to conduct water supply or serve as drains in both rural and urban areas. Most concrete pipe water supply as well as drainage and sewer systems that have been constructed in the earlier century still stand strong and function as efficiently as when they had first been constructed.
Concrete pipe shapes and sizes
Concrete pipes are available in a variety of shapes and sizes. The five most common shapes include the circular, horizontal elliptical, the vertical elliptical, the arch and the rectangular ones. The shape of the pipe would depend upon the project or activity in which it is to be used. It would also depend upon the topography of the site, the cost and the structural efficiency of the project as well. Since concrete pipes are mostly used as conduit material, they are generally used where they would help in the natural flow of water supply or drainage as the case may be.
How are concrete pipes made?
There are many ways of making concrete pipes. Some of these methods use dry concrete mix to make concrete pipes. These methods include the centrifugal or spinning method, the dry cast method, the packerhead method and the tamp-entail method. Another method of making concrete pipes called the wet casting method makes use of a high-slump concrete mix. The basic materials for making concrete pipes are the same as for other concrete products such as cement, gravel, sand and water. In some projects, steel reinforcements may also be used for adding more strength to the concrete pipe structure.
Uses of concrete pipes
Concrete pipes have been used in irrigation systems, water supply lines, sanitary sewers, storm drains as for unblocking storm water drains. Concrete pipes are the best conduit material for supply of water to farmlands and also for water supply to large cities as well. Most drainage systems also make use of concrete pipes. Storm drain systems play a very important role in crowded towns and cities and help in reducing the damage caused by floods.
Concrete mold is mainly a way of using concrete to its optimum. Concrete can be patterned or molded into any shape or pattern. Concrete molds are mainly used for decorative purposes. Sometimes they may have functional use as well. They are used in constructing stepping-stones, fountains in lawns or in the exterior of the homes.
Designs with Concrete Mold
Precast concrete molds can be used to create beautiful walkways, asphalt driveways Perth and patios or just about anything, which requires concrete mold to resemble brickwork or cobblestone. The concrete, using cement, other aggregates and available colors, is mixed and poured into the reusable molds to create entire lengths of pathways. Curing takes time and the surface of the concrete after it has been laid and is dry, may require the use of sealers to smoothen as well as strengthen the surface. Molds can also be custom-made and are affordable with the added benefit of being reusable.
How is a Concrete Mold Prepared?
Mold release is applied to the mold keeping in mind that too much of it is not used. The cement is mixed according to instructions or quantity required and is then poured into the mold. Half of the required quantity is poured into the mold. After shaking and tapping the bottom of the mold for the cement to settle in, the other half of the cement mixture is also poured into the mold. The mold is again shaken and tapped for the top surface to become flat and even. The mold must be kept in a dry area for at least 24 hours to dry completely. To unmold the stone, the mold is turned upside down and is lightly tapped to take out the stone.
Uses of Concrete Mold
Concrete mold is used more for decorative purposes. Lawns, designed landscapes, paths, walls, fountains or even steps to entries or decks can be decorated using concrete mold. Precast concrete can be designed to resemble people, animals or even abstract objects or themes. Long lasting and virtually maintenance free, concrete mold is very popular with homeowners who have huge lawn area available for decoration or design.
