Block paving on a concrete base However, if there is no fall, and water does not drain easily, then it will sit just below the blocks. This will cause an uneven surface, the growth of weeds and grass, and can eventually lift the blocks from place.
Likewise, people ask, does block paving need drainage?
You will not need planning permission if a new or replacement driveway of any size uses permeable (or porous) surfacing which allows water to drain through, such as gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally.
Secondly, do I need drainage for my driveway? The long and short of this is that all driveways need to have proper drainage. This can be either via permeable surfaces or via a drainage system when your driveway is installed.
Also to know is, does block paving let water through?
Concrete Block Permeable Paving (CBPP) differs from conventional block paving because it allows water to soak through the driveway, preventing water from amassing and flooding. This is laid on top of a sub-base which allows water to be stored and pass through while still allowing driving and parking.
Can block paving be relaid?
It is important that any relaid block paving is compacted. But before any compaction of the block paving takes place you first need to sweep clean the paved area. The paving edges need to match up to the existing paving that has not been relaid. It needs to be level to stop any trip points.
What weight can block paving take?
Note: 60mm block paving can take up to 10 tons of vehicle weight whilst 50mm block paving is only intended for light pedestrian traffic and is therefore unsuitable for most modern driveways with large family vehicles and 4 x 4's.How long before you can park on block paving?

How do you install block paving drains?
How to build a land drain- Dig a trench about one metre deep and 350mm wide, with a fall towards the outlet (to a soakaway or surface water drain).
- Line your trench with permeable geotextile fabric and lay 20-40mm of clean aggregate to a depth of 75mm in the bottom.
Is block paving porous?
Hard permeable and porous surfaces Hard surfacing which allows water to soak into it can be built with porous asphalt, porous concrete blocks, concrete or clay block permeable paving. The material has open voids across the surface of the material or around the edges of blocks that allow water to soak in.How do I fix a puddle in my driveway?
