Block Paving Design Guide
Choice of Two Paving Systems
Block Paving Design Guide
Although the Government Legislation for paving of front gardens has changed, it is good news for Householders as there are now two paving systems that do not require planning permission and you can use either of them to transform your driveway and front garden with a choice of creative landscaping.
Plaspave Permi.8 permeable concrete block paving systems are constructed differently to Plaspave conventional impermeable paving systems but both types of surface have a sub-base layer constructed strong enough to carry designated traffic loads without rutting.
CONVENTIONAL PAVED SURFACES
use a sub-base material called hardcore or MOT Type 1 material which once compacted stops water passing through it easily. Wherever it is possible to provide rainwater run off from a driveway into a soak away or onto a rain garden contained within the boundary of a property then Conventional Block Paving may still be used without the need for planning permission.The comprehensive range of Plaspave landscaping products remain suitable for these applications.
N.B. If a conventional impermeable surface is required and run off onto the road cannot be controlled then a planning application will be required which will incur additional costs and may or may not be granted.
PERMEABLE PAVED SURFACES
require a different sub-base material that allows water to pass through and also store the water until it can eventually be dissipated by various methods. If rainwater run off cannot be controlled, Permeable Block Paving can be used to construct an appropriate permeable paving system. The sub-base aggregates are 4mm-20mm MOT Type 3 sub-base, crushed, clean and open graded pieces of stone that have spaces between to store water. The laying course and joint filling material is 2mm-6mm angular, crushed, clean gravel as conventional jointing sand is not suitable as a medium for surface water to pass through the paving systems.The Plaspave Permi-8 range of permeable landscaping products provides a comprehensive product choice for these applications.
