Traditionally resin bound materials have been laid onto asphalt and concrete bases. However, with increasing requirements for permeable paving and of course cheaper projects there was a need for further investigation on suitable base options.
This is a mixture of stones graded from 4-40mm and provides a minimal build up suitable for light pedestrian use. It’s ideal for tree surrounds or trenches providing root protection. Using type 3 offers a very permeable and durable solution, which is very important especially around trees or pathways surrounded by any plants or trees that require a water source direct to their roots.
Resin Bound paving can be laid over the existing soil of an established tree, providing that the soil is stable and free draining. If an area like this happened to be overrun by vehicular traffic, the structural layers need to be designed in accordance with the Highways Agency requirements.
Plastic cellular structures
The use of plastic grids offers a stronger load bearing base than just type 3 and therefore can be used on heavier trafficked areas. This type of honeycomb structure also ensures a fully permeable system which uses recycled plastics and can also be filled with recycled gravel or even glass.
Porous asphalt, some may refer to this as tarmac. It is a strong and stable base, suitable for heavy pedestrian and vehicular use.
A Resin Bound Base
This is made with a mixture of loose gravels that are bound together, providing a durable and permeable base suitable for light use.
At SureSet, we will work with you to suggest what the correct base is for you depending on the application and its use. Choosing the correct base will ensure that your resin bound paving is fit for purpose and will maintain its maximum life span.
