Watch video of Topmix permeable concrete. Topmix Permeable is a fast draining concrete pavement solution that rapidly directs stormwater off streets, parking surfaces, driveways and walkways. This minimises the cost and long-term maintenance for local authorities and developers of stormwater management.
This video briefly introduces the concept of groundwater before explaining how two properties - porosity and permeability - combine to determine the availability of groundwater and the ease with which it travels through rocks and sediment. We show simple bench-top demonstrations to illustrate each property and we calculate what a reasonable porosity value would be for common sediments such as sand and gravel. Finally, we discuss which rocks would best serve as sources of groundwater and which are likely to be barriers to groundwater flow.

Pervious concrete is made using large aggregates with little to no fine aggregates. The concrete paste then coats the aggregates and allows water to pass through the concrete slab. Pervious concrete is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and greenhouses. It is an important application for sustainable construction and is one of many low impact development techniques used by builders to protect water quality. Pervious concrete was first used in the 1800s in Europe as pavement surfacing and load bearing walls. Cost efficiency was the main motive due to a decreased amount of cement. It became popular again in the 1920s for two storey homes in Scotland and England. It became increasingly viable in Europe after WWII due to the scarcity of cement. It did not become as popular in the US until the 1970s. In India it became popular in 2000. What would it feel like if the first reaction when people see your house was WOW!

Oklahoma Gardening's Kim Rebek talks with OSU Extension stormwater specialist Jason Vogel about the differences between pervious and traditional concrete and learns how to correctly mix pervious concrete.
ASTM 1701 is the test for pervious concrete infiltration. This video shows how to use that test to measure the infiltration rate of pervious concrete. It is out recommendation to perform and infiltration test at least annually to determine the need for maintenance. This concrete brief is hosting by Steven Tripp, marketing and concrete geek.
Tarmac has created Topmix Permeable, a porous concrete that allows rain water to flow though it. Up to 880 gallons of water can trickle through Topmix, which could eliminate flooding where it has been installed.

Porosity Determination Using Liquid Saturating Method
Concrete Permeability Apparatus is used for testing the water permeability of concrete. High pressure permeability test are conducted on various sizes of specimens by different cells. Herein, Cell is available with a top plate and funnel fitted at the bottom that comprises gasket seals held in position by various nuts &bolts. The concrete specimens are sealed inside the cell to avoid any leakage beside the side walls. Each unit is available with test pressure gauge of 0-15kg/cm² and chamber pressure gauge of 0-20kg/cm2. As a result, pressure can be applied using any available pressure line at the compressor or site. It can be supplied without compressor and glass bottles.
