They must be <\/span><span data-contrast=\"auto\">holistically<\/span><span data-contrast=\"none\"> designed to ensure that water containment and drainage is managed within the plot of the building development.\u00a0<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">There is an increasing demand for sites to achieve SuDS (Sustainable Drainage System) compliance. SuDS takes a natural approach to managing rainwater. It does so in a way that reduces the risk of flooding, improves water quality and delivers a durable drainage system. Permeable paving can drain rainwater at the point at which it falls, filtering out sediments and reducing pollutants. Therefore, specifying permeable block paving helps to mimic the natural drainage of open land and aids SuDS compliance.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">In England, SuDS can be recommended by planners but not enforced by law. Section 3 of the Flood and Water Management Act 2010 is designed to help with surface water management in urban areas. It was implemented in Wales in 2019 and in 2025 the government has stated it is strongly committed to requiring standardised SuDS in new developments. If Section 3 is eventually implemented in England, paving over 100 square metres will require approval from a sustainable drainage approval body (SAB), making permeable paving an attractive and cost-effective option for specifiers, and also a legislative requirement.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<h2><b><span data-contrast=\"none\">How do the ground conditions affect the infiltration strategy specified?<\/span><\/b><span data-ccp-props=\"{}\">\u00a0<\/span><\/h2>\n<p><span data-contrast=\"none\">The design of the sub base layer underneath <\/span><a href=\"https:\/\/about:blank\/\"><span data-contrast=\"none\">permeable block paving<\/span><\/a><span data-contrast=\"none\"> can be altered to deliver different water infiltration strategies. The infiltration strategy required will depend upon the permeability of the ground beneath the sub base and\/or the need to contain all the water at source.\u00a0<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">Surface water first drains through the joints of permeable block paving blocks. It then enters the sub base aggregate layer.

This directly mimics how rain falls on open ground. It provides total infiltration of rainwater.

rainwater, the sub base provides the foundation to support the permeable block paving. A 4\/20mm coarse graded aggregate to BS EN13242:2002 is used for the sub base. This provides the required support and has no fines that could clog the system and reduce its efficiency.\u00a0\u00a0<\/span><span data-ccp-props=\"{&quot;335572079&quot;:6,&quot;335572080&quot;:1,&quot;335572081&quot;:0,&quot;469789806&quot;:&quot;single&quot;}\">\u00a0<\/span><\/p>\n<p data-ccp-border-top=\"0px none \" data-ccp-padding-top=\"0px\" data-ccp-border-bottom=\"1px solid #000000\" data-ccp-padding-bottom=\"1.3333333333333333px\"><span data-contrast=\"none\">The depth of the sub base will depend upon both the traffic category and the underlying soil strength.\u00a0 The depth and composition of the sub base should be determined by a suitably qualified ground engineer. For traffic categories C, D, E and F, a layer of DBM (Dense Bitumen Macadam) is added to increase structural support. This layer is cored before the laying course and blocks are installed.<\/span><span data-ccp-props=\"{&quot;335572079&quot;:6,&quot;335572080&quot;:1,&quot;335572081&quot;:0,&quot;469789806&quot;:&quot;single&quot;}\">\u00a0<\/span><\/p>\n<p data-ccp-border-top=\"0px none \" data-ccp-padding-top=\"0px\" data-ccp-border-bottom=\"1px solid #000000\" data-ccp-padding-bottom=\"1.3333333333333333px\"><span data-contrast=\"none\">It is usually the case that the depth of the sub base for structural purposes will be greater than that required purely for water-retention purposes. This increases the water holding capacity of the sub base layer. Permeable paving is typically designed to accommodate a 1:100-year rainfall event.<\/span><span data-ccp-props=\"{&quot;335572079&quot;:6,&quot;335572080&quot;:1,&quot;335572081&quot;:0,&quot;469789806&quot;:&quot;single&quot;}\">\u00a0<\/span><\/p>\n<h2>Why is it important to correctly specify transitions between permeable and impermeable paving?<\/h2>\n<p>Detailing the smooth transition between areas of permeable and impermeable paving is important to ensure the overall efficiency of site water management. Rainwater displaced from impermeable surfaces will add extra loading onto adjacent permeable paving. The sub base specification, depth and permeable infiltration system will need to be specified to handle the expected volume of water.<\/p>\n<p>The example here shows the transition between permeable paving and sub base on one side of a flush kerb. The other side of the kerb is made up of non-permeable blocks on a non-permeable sub base.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-24831 size-large\" src=\"https:\/\/www.tobermore.co.uk\/professional\/wp-content\/uploads\/how-to-specify-the-correct-permeable-paving-system-for-your-project-1024x576.jpg\" alt=\"\" width=\"1024\" height=\"576\" \/><\/p>\n<h2 data-ccp-border-top=\"0px none \" data-ccp-padding-top=\"0px\" data-ccp-border-bottom=\"1px solid #000000\" data-ccp-padding-bottom=\"1.3333333333333333px\"><b><span data-contrast=\"none\">Can permeable paving be specified on sloping sites?<\/span><\/b><span data-ccp-props=\"{&quot;335572079&quot;:6,&quot;335572080&quot;:1,&quot;335572081&quot;:0,&quot;469789806&quot;:&quot;single&quot;}\">\u00a0<\/span><\/h2>\n<p data-ccp-border-top=\"0px none \" data-ccp-padding-top=\"0px\" data-ccp-border-bottom=\"1px solid #000000\" data-ccp-padding-bottom=\"1.3333333333333333px\"><span data-contrast=\"none\">Permeable paving can be specified on sloping sites that have a slope less than 1:20.

In addition, permeable systems require less maintenance. The UK guidelines require the infiltration rate of permeable paving surface joints to be 400mm an hour. This is only 10% of the actual rate of newly installed permeable paving. Allowing for medium and longer-term clogging, this represents a large, built-in safety factor.
