How plastic porous pavers can help provide a durable yet naturally water absorbent area of grass or gravel hard standing to comply with current planning regulations.
The need to regulate water drainage means controls over hard standing
Since 2008 property owners looking to pave a front garden must, under certain circumstances, to apply for planning permission due to the need to control the amount of rain water entering the drainage system at once.
Increased amounts of hard standing as a result of town and city expansion and the general trend for householders to increase hard surface areas around their properties has put our drainage systems under pressure so regulation is required.
The drainage issue
The UK’s drains are coming under greater pressure; more flooding has been experienced in built up areas after periods of heavy rain as drains find it hard to cope with increasing amounts of water entering them during and after rainfall.
Consequently, more absorbent materials such as gravel and permeable block paving, perhaps in conjunction with porous pavers – a honeycomb-style plastic grid base for gravel of even grass such as these Suregreen porous pavers – are becoming more popular in the construction of hard standing areas.
Why are the amounts of water increasing?
Two main reasons:
– as towns and cities expand, more naturally absorbent land is being covered over with hard surfaces such as concrete and tarmac as more houses, other buildings and hard surfaces such as pathways and roads are built.
Trend for hard standing amongst householders
– with the rise of car ownership more off road parking is desirable, so more householders are replacing naturally absorbent grass and earth areas usually to the front of maybe sides of their properties with hard surfaces for parking.
As a result, more rain water runs off these hard surfaces and straight into the drains instead of being absorbed naturally as in the case of grass and earth land areas. This is putting more pressure on the drains with a resultant increase in flooding; couple this with a general climatic change to larger rainfalls over shorter periods of time and the problem is increased.
Homeowners are being encouraged to use permeable materials and drainage solutions to help water drain naturally into the ground instead of running off into the drains directly.
To this end, planning regulations decree that planning permission is required if a homeowner wishes to pave their front garden with a hardstanding of more than five square metres if they ARE NOT using a permeable material.
Using permeable materials such as gravel and porous paving means water can behave as it would when falling onto or running along natural land areas; it will be absorbed gradually into the ground beneath the hard standing and enter the drainage system in a more controlled manner.
Plastic porous pavers provide a firm base for materials such as grass and gravel that are prone to being moved after a period of use yet still provide the absorbency required to comply with planning regulations.
While gravel or grass might be initially less in favour in heavy use areas, the laying of porous pavers will add considerably to their durability. So much so that heavy use car parks such as those located at certain tourist attractions use them with natural grass to provide hard wearing car parking.
