Traditional Block paving is sized 200 x 100mm and is available in 60 & 80mm thicknesses for commercial application and 50mm thick for domestic situations.
Blocks are laid onto a compacted sand bed which has been screed to the required levels.
After laying the block paving to the desired pattern the perimeter blocks are cut to the edge using a guillotine paving cutter. Finally the blocks are covered in kiln dried jointing sand before compaction with a plate vibrator and a final sweep to fill the joints with sand.
There are many other sizes of blocks now on the market, often referred to as sett paving but typically the thickness remains at 50,60 or 80mm. All blocks are available in a variety of surface finishes and colors.
And most paving problems issued in manhole areas and any different connection with other materials, as mentioned in picture below for ma hole and it's steel cover connection with interlock.
PERMEABLE BLOCK PAVING
Much like traditional block & sett paving in appearance the installation method is different. Permeable paving is laid on a bed of fine angular stones onto a sub-base formed with fines stones. Surface water permeates through the paving into the sub-base before either eventually filtrating into the ground, watercourse, water harvesting tank or main drains. Interlock Paving have been laying these products since they came onto the market and are an approved installer of Hanson Formpave's permeable paving, the company that founded the system in the UK.
