The non-monolithic surface of precast concrete pavers allows them to minimize the impact on the local environment. Where a paved surface is necessary, the segmental pavers can be integrated with the functions of the earth and environmental conditions thereby reducing the overall impact that a monolithic surface might impose.

This study is focused on the implementation of interlocking pavers in marshy roads and high groundwater table terrain. Permeable interlocking concrete pavers were used to combat intrusion of underground/saline water for the road of case study (Akin-Adesola Street, Victoria Island, Lagos). Hydrogeologic data, i.e., groundwater level information for marshy roads terrain including the area of case study was obtained in form of investigation hole/borehole data. Different scientific tests and researches put together show the effectiveness and durability of the modified exfiltration system type of permeable pavement for high ground water table terrain. 

When it comes to permeable paver design, several factors go into making a functional system.  One must size the system appropriately taking rainfall, infiltration rates, available area, void space, layer depth, and time all into consideration.  This lesson will introduce you to all those critical factors in these three lesson components:

Location is Everything.
While designing paving systems, you must consider location.  It rains DIFFERENTLY in California than Alabama. Each system can have a number of different soils, each draining and retaining water DIFFERENTLY.  Lets take a deeper look into how rain events, annual precipitation and soil type effect permeable paving systems.

This learning animation walks you through many of the considerations for designing a ICP system.  Topics range from rainfall events, geographic range, soils, and substrates.  After completing the learning section, an interactive site allows your to choose different combinations of parking surface areas and base depth to hold a particular rain event.

It is the goal of this guide to improve the design of the paved plane of the built environment by expanding the level of knowledge about concrete pavers. This will be accomplished through the organizing of information and support material for both the instructor and the students.
