A Guide To Laying Pavers And Paving Stone

asphalt-paving-stonesYou should always dry lay your patio first, before you get to work, this isn’t a difficult feat but simply involves laying the paving out exactly as you want it to be when you’ve completed the job. Size and layout are big factors to look out for, but the most crucial step here is to make sure you won’t be short of paving slabs!

The First Step: Layout Of The Patio Foundations

For foundation mix and paving you should allow 150mm. When laying directly beside the house the completed patio needs to be a minimum of 150mm depth from the damp proof course. In practicality, this calls for you to dig a 300mm minimum depth below the damp proof course.

A fall of 1 in 60 is required to eliminate the problem of water gathering on the paving, this means one centimetre of fall is required for every 60 centimetres of width. For example, a 50mm (5cm) would be required for a patio which is 3m wide.

The Second Step: Foundation Base Preparation

A concrete mix of 1 part cement to 6 parts all-in-one ballast will create a firm foundation. You want the mixture to just bind and no more, so mix and add enough water to reach this consistency. Next, to a depth of 75mm, get the whole area covered, using a shovel to level the surface. Use a length of wood, or simply your boots, to trample the surface down.

The Third Step: Preparing The Mortar

You want the whole slab, not just the corners, to be supported, so lay the paving slab on a full mortar bed. The mortar mix should consist of 1 part cement and 6 parts sharp sand. Add just enough water to create a damp and malleable mixture, without allowing it to become runny.

The Fourth Step: Time To Lay The Paving

In order to guide the line and level of the paving you need two taut string lines set up. One of the lines should run from side to side, while the other runs the length of the patio, make sure one of the lines has the drainage fall. Begin the process at a corner, gradually working your way out. Use the mortar to create an area that is a little bigger than the planned paving slab, it should also be an adequate height to allow you to tap the flag down to reach the right level. Next, being very careful not to catch any of the corners, lift the slab and lower it into place.

Now begin to tap it down using a rubber mallet. Use your imagination to create diagonals halfway from the middle of the paving slab and the corner, this is the spot you want to hit with the mallet aiming for a firm, yet not too strong, strike. Do this for each corner, Tapping each point in turn and continue the process until the flag has nestled down and is sitting at the correct level. Use a spirit level to check that the paving is level and also ensure that you have a fall, once these factors are confirmed, continue with the rest of the paving, when necessary leaving joints. Once all of the patio has been completed, it needs 24 hours to fully harden, hence it is important for no one to walk on the paving.

The Fifth Step: Time To Get The Paving Jointed

Create a smooth, but not sloppy, consistency using 1 part cement and 3 parts soft building sand. If you want to make life a little easier use a plasticiser.

Next it’s time to trowel the mortar into each joint, make sure you press it down, if it seems necessary use a pointing bar to smooth it out. This step calls for extra caution to make sure you don’t get any mortar on the paving slab. It is possible to scrape mortar off the slab, but you should wait a few hours until it has begun to harden.

Check that the mortar has fully hardened, then give the patio a thorough brushing – all that’s left to do after that is give yourself a pat on the back for a job well done!

Paving Blocks Uses

The very first highways, built on the isle of Crete, were constructed using paving blocks. Rome is lined with smooth roads built using trimmed stones. But as old as it is, the Roman method is still commonly used today for paving anything – from roads to sidewalks.

Working with paving blocks is done by interlocking stones. This concept started in the Netherlands, and is still being used for laying bricks today. The blocks are made of clay or concrete and set in sand. They are generally stronger than paving or asphalt and are simple to repair and maintain. They may even withstand earthquakes.

Benefits of using paving blocks instead of asphalt are numerous. They are available in many colors and patterns which can be easily mixed and matched, making it is easy to create a unique, beautiful design. Your driveway is the first thing people see when they come to your home. When laid with paving stones, it definitely will stand out. If done properly, they will hold much longer and will require less maintenance.

Other paving materials include clay-based bricks, stamped cement and cobblestone. You can also do it yourself, although the best way is to leave the laying and installation to professionals. Paving prevents the asphalt from splitting and prevents unwanted changes in the road surface that occur because of being exposed to the elements.

The Things You Need to Know About an Asphalt Paver

Construction Worker during Asphalting Road WorksWe’ve been riding on smooth and paved roads today because of the help of many construction machines that made a lot of things possible for us. It made driving to far away locations easier and more comfortable. Asphalt is the main material commonly used in paved highways. This is an inexpensive building material that is easy to use and quick to apply because it dries up very easily. Asphalt paving is very durable and can withstand all weather conditions and heavy loader vehicles and trucks. The machine used to lay the asphalt properly is an asphalt paver.

The asphalt paving machine is used to mix, compact and apply asphalt uniformly in roads, parking lots, and other paved areas. This is an important equipment that allows contractors to build the highways and lanes which we have today. The asphalt paver is usually attached to the back of a dump truck but there are already self-propelled pavers that do not need to be towed by a truck.

The 2 key aspects of the self-propelled concrete paver is the tractor and the screed. The tractor mainly is made up of the generator, and it is used to propel the paving machine forward and to distribute the asphalt. The screed has a thickness gauge control and is used to level and control the layer of the asphalt. It also has a wheeled roller to compress the pavement as asphalt is laid on the road.

Before the actual laying of the asphalt, the paver must be filled with asphalt. The tractor will then move the paver forward and the asphalt will be pushed toward the back in a feeder conveyor while the augers will be spreading the asphalt to the width needed for the job. The heated screed will begin leveling and compacting the asphalt, making sure that the layer is evenly distributed on the surface. Sometimes a roller is need to compact the asphalt more.

The asphalt paving machine is made mostly of metal and the mainframe is constructed from premium high quality metal plates. The tractor and screed are built as a stand alone unit and they must be installed properly to function well. A concrete paver finisher is sometimes used to complete the paving process and manufacturers include this part with every self-propelled pavers they make.

The asphalt paver is a very important machine in the building and the completion of pavement and streets. The paving machine must be of high quality and durable in order to function properly for a long time. This machine is an essential part in any road construction company.
