Linne comes with a classic rectangular block profile and purpose designed nibs to enhance permeability.
This contemporary, clean style will complement most environments and has been designed for use in either hand or machine lay applications.

Structural Design
Permeable pavements must be designed to deliver two objectives:
Two sets of calculations are there fore required when designing permeable pavements.

Application and Installation
Is suitable for a wide range of paving applications.
For further details please refer to BS 7533 Part 3: 2005 and Part 13: 2009.
PLEASE NOTE: This product is specifically designed to be hand or laid in permeable pavement applications with permeable sub-base materials and techniques.
Texture
Smooth surface with a 6 x 4mm chamfered edge.
Manufacture
Caledonian Interlocking Concrete Blocks are manufactured and in accordance with BS EN 1338:2003.
Permeability Rates
This style of permeable paving has been independently assessed to have a water permeability rate of 4,265mm/h when laid in accordance with our recommendations. This compares with a typical UK rainfall intesity of 75mm/h.
Strength
Characteristic tensile splitting strength not less than 3.6Mpa when tested in accordance with BS EN 1338:2003.
Abrasion Resistance
The abrasion resistance is designated as Class 3, when tested in accordance with BS EN 1338:2003.
Hydraulic Design
System A: Total Infiltration
All water falling onto the pavement infiltrates down through the joints between the concrete blocks, passing through the constructed layers below and eventually into the sub-grade. The sub-base layer may act as a temporary storage device.
System A: Total Infiltration
Similar to System A but with a series of perforated pipes or fin drains at the formation level at the bottom of the sub-base to allow the remaining water to be drained to other systems such as sewers, swales and ponds or watercourses.
System A: Total Infiltration
Allows for the complete capture or attenuation of the water using an impermeable membrane placed on top of the formation level. Pipes or fin drains restrict the outflow of water from the pavement.
Run off control
Conventional pavements, car parks and hardstanding areas are designed to simply shed water from their surface, whereas permeable pavements allow the water to pass between each block and into the underlying sub-base
Pollution control
The second major benefit of permeable pavements is their ability to reduce pollutants, at or close to the source
Space efficiency
Permeable pavements are a very space efficient solution and ideal for high density housing and construction projects
