A step by step guide to a typical block paving installation.

The all important preparation

Before any setting out can commence the proposed area needs to be cleared of all shrubbery and foliage etc.

     
  Excavation of proposed area can now take place. A mini digger and breaker will now be used to reduce ground levels to a minimum of 200mm.

     
  Cart away to tip is carried out by grab lorries once excavation is completed.

     
  The ground can now be prepared and compacted.

     
  The installation of surface water channels,  recessed manhole covers, soak aways and drain surrounds is now carried out.


     
  Laying of sub base material. It is essential it is at least 100mm thick, void free, set to falls and is fully compacted.

     
  Weed suppressing fibre glass matting is then laid between the sub base and the sharp sand laying course.


     
  Spreading of sharp sand to a depth of 50mm, then compacted with a plate vibrator then a further 15mm is loosely screeded over the top. For drainage purposes a slope needs to be created dropping 2mm over 1m across and 25mm over 2m length.


     
  Laying of your choice of blocks, cobbles or slabs then takes place.

     
  Jointing sand is now swept over the entire area ensuring all joints are filled and a final compaction can now take place .

     
  The finishing touches can now be added, such as gates, railings, and connections to lighting.

     
  Your installation is now complete and ready for use.
