Block Paving Is a Sound Investment

Service general groundwork

You’ll find some great examples of block paving in Cambridge, all of which add beauty to the outdoor spaces in which they can be discovered. Paving bricks are available in many different forms and colours and provide stable, reliable surfaces underfoot. Each one is tough for years of low-maintenance service. The type of block chosen will decide the kind of maintenance necessary. Appropriate, normal maintenance will make certain your block paving investment remains safe for the long term.

Kinds Of Block Paving

Make sure you know which type of paving is installed prior to carrying out upkeep. Typically, there are two kinds of block paving available, permeable and impenetrable. A porous block paving is produced so that water can run through it, and drain into the ground below. An impervious paving will not allow water to flow through it, but instead, water flows over surface of the paving and over adjoining surfaces. Impervious paving can be installed to permit water to drain in between the paving, providing it a equivalent element to the permeable paving. Permeable paving can be more delicate than impenetrable paving, and roughly employed maintenance techniques could cause premature crumbling of ends and corners.

The type of block chosen can also rely on the purpose and location of the installation. Ecological factors play an ever more significant component in the management of water in metropolitan locations. Impermeable paving guides storm water into water treatment plants but is typically sturdier than porous blocks. Permeable paving allows storm runoff to be purified by the ground onto which it falls. Permeable paving is becoming the preferred choice because it reduces stress on public water treatment facilities.

Crumbled Paving Could Imply Trouble

Damaged paving might indicate improper installation. Replacing these may be necessary to stop falls. While replacing blocks, make sure you verify the base above which they were installed. Set up of either kind of block paving is similar. The ground beneath is excavated of natural soil and filled with gravel and sand. This kind of base offers firmness for the paving and can stop them from damage later on.

Maintenance Suggestions To Retain Function And Beauty

Both kinds of paving will require normal upkeep to retain their beauty and function. As time passes, the gaps in between impervious blocks will become blocked with soil along with other debris, which will hinder their drainage function. It can be anticipated that this build up of silt will trigger a sluggish loss of function over time; research show it stabilises out between 3 to 6 years.


Frequently brushing off debris will stop staining and the development of moss or weeds. When silt, moss or unwanted weeds become unmanageable, a power washer could be employed to eliminate them. Nonetheless, care must 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 necessary for persistent unsightly stains or grounded moss and mildew. Be sure to add additional joint sand if any was dislodged. Correct sanding will retain the stability of the block and sealing the blocks may minimise or eliminate maintenance completely.
