ABOUT PAVING BLOCKS
Block paving has increased in popularity over the past 10 to 15 years. The introduction of large production types and techniques has helped reduce the costs involved in manufacturing paving blocks. It has also improved its affordability, making it a popular and preferred choice. There are many areas around residential and commercial properties where block paving can be applied. Driveways, patios, walkways, courtyards and pathways are all popular applications whether the area is big or small. It can be designed to suit the size, and width of the area to help create a unique and stylish appearance.
Block paving is also becoming popular in public areas. It is vastly replacing asphalt in areas such as walkways, sidewalks, car parks, shopping centers, air ports and some urban roads. The choice of design is endless with the block and it is easy to achieve any possible style. Any type of patterns can be constructed and produced in block paving which is a huge advantage.
Concrete Block Paving
|Concrete is commonly referred to as blocks when used in paving. It is one of the main types of block paving used nowadays. Concrete is sold in individual units with the range of size, thickness and width to suit any type of application. Thick blocks are generally used for high traffic areas where durability and strength are required. Thinner concrete blocks are generally used for low traffic residential areas such as patios or landscaped gardens.|
Concrete block paving is very common and popular in modern times because of its low costs and endless style, pattern, color and design options. The coloring process is very similar to concrete because the use of color pigment dyes is used in the production of the concrete mix. Colors in block paving will generally fade due to wear and ageing so it is important to consider all color choices before choosing the right tone for your block paving application.
Block Paving Installation Methods
There are 2 very simple methods that are used to lay block pavers. The methods are designed to suit all types of materials. Flexible pavement is a common method that is generally used for almost every method of block paving and every material. It is where a crushed stone or sand base material is used. Block paving units are then installed directly on top of the base material in a laying pattern and once completed the joints are filled with sand by sweeping the sand over it.
The second method is where the paver is installed on to a bed of poured mortar or concrete to hold it in its place. The pavers are kept apart by a joint spacer and laid in a pattern or style. Once the paving is complete the joints are filled with mortar or concrete depending on the choice of material.
Block Paving Maintenance
Block paving requires low and simple maintenance. It is recommended to treat the pavement with a pesticide that gets rid of weeds that may grow between the joints of the block units at least once a year.
It should be swept over regularly to remove all dirt, debris and grime that could eventually cause stains and damage the pavements.
The use of sealants is recommended every 3 to 4 years to protect the color and topcoat of the pavement. General repairs may be required to the overall structure in case of cracks or chips, so it may be wise to order 5% more material before installation to allow for repairs. Hosing down the pavement with water is also a good idea to remove dirt off the surface of the paving.
