There are some great examples of block paving in Cambridge, which add beauty to the outdoor spaces in which they can be found. Paving bricks are available in many different shapes and colours and offer steady, reliable surfaces underfoot. All are tough for many years of low-maintenance service. The type of block chosen will determine the kind of maintenance required. Appropriate, regular upkeep will ensure your block paving investment remains safe for the long term.

Kinds Of Block Paving

Make sure you know which kind of paving is put in prior to carrying out upkeep. Generally, there are two types of block paving offered, permeable and impenetrable. A porous block paving is manufactured so that water can run through it, and drain into the ground under. An impervious paving does not allow water to circulate through it, but rather, water flows over surface of the paving and over adjacent surfaces. Impervious paving can be installed to enable water to drain between the paving, giving it a similar element towards the permeable paving. Porous paving can be a lot more sensitive than impenetrable paving, and roughly employed upkeep techniques may result in early crumbling of ends and corners. cambridge block paving prices per m2

The kind of block selected can also depend on the purpose and location of the installation. Environmental elements play an increasingly considerable part in the management of water in metropolitan areas. Impenetrable paving guides storm water into water treatment plants but is generally sturdier than porous blocks. Permeable paving allows storm runoff to be purified by the ground on which it drops. Permeable paving is now the preferred choice because it reduces stress on public water treatment facilities.

Cracked Paving Could Mean Trouble

Cracked paving might indicate improper installation. Replacing these could be necessary to prevent falls. When replacing blocks, be sure to check the base more than which they were installed. Set up of either type of block paving is very similar. The ground under is excavated of natural soil and filled up with gravel and sand. This base gives firmness for the paving and will prevent them from damage in the future.

Upkeep Tips To Retain Function And Beauty

Both kinds of paving are going to require normal maintenance to preserve their beauty and function. As time passes, the gaps between impervious blocks will become blocked with dirt and other debris, which will inhibit their water drainage function. It could be expected that this accumulation of silt will cause a sluggish decrease of function as time passes; studies show it stabilizes out between 3 to six years.


Regularly brushing off debris will stop staining and the development of moss or unwanted weeds. When silt, moss or weeds grow to be unmanageable, a power washer could be employed to eliminate them. Nevertheless, care has to be taken not to dislodge an excessive amount of of the jointing sand in between the paving stones. More caustic cleaners applied with a soft brush may be required for stubborn unsightly stains or rooted moss and mildew. Make sure to add additional joint sand if any was dislodged. Appropriate sanding will support the stability of the block and sealing the blocks may minimize or eliminate upkeep altogether.
