Understanding Resin Bound Bases

Installing a resin driveway is as important as mixing and laying the system.

What is the difference in a base and sub-base?

Two bases are essential for resin bound installations: the base and sub-base. Although they can be confusing to identify, each base is important and equally important.

What's the base?

The base is the surface on which the resin bound system will be applied and bonds. This is also known to be the binder course’. The term “base” can sometimes be misinterpreted to mean the entire structure below the resin bound system (including its sub-base). It is important to understand the differences.

What is the subbase?

As the name implies, the subbase of a resin bound material is the area that lies below the base or ‘binder’. A solid subbase not only improves the strength but also gives the base a level platform.

What is the best resin-bound system sub-base?

If you plan on laying a permeable layer above your subbase (such an open course macadam), then your subbase should be MOT type 3 compacted. MOT type 1 is recommended if the base is not permeable and has sufficient slope to allow water flow into a drain.

Permeability is required for resin-bound installations to be SUDS compliant.

What are the main Resin Bound course materials?

Concrete and macadam constitute the preferred binder or base material for resin bound system. Each one has its own advantages and disadvantages.

The following information shows a typical base construction and best practices.

Resin-bound tarmac base

Macadam refers to a type or construction surface that is made up of successively compacted layers broken stone, bound by tar and bitumen. The Macadam system is suitable for resin bound systems that are permeable to water and SUDS compliant.

The base for macadam is a 50mm thick porous surface course macadam with a 14mm close graded porous surface.

Concrete base with resin-bound concrete

Concrete is one of most popular building materials around the globe. Concrete usage worldwide is double that of steel, aluminum, plastic, and aluminium.

A concrete or binder-course can be used as a base for a resin binding system. However, it will not be permeable and will need additional drainage.

C25 smooth-brushed concrete should be used as the concrete base. The concrete must also be properly cured before resin bound driveways are installed.

Does an existing driveway base work well with Resin Bound?

It is important to be aware of the following things before you begin laying resin bound surfaces on an existing base. These are:

  • Are there steps that are difficult?
  • Are there cracks or holes in the base? These cracks need to be sealed with a layer membrane.
  • It is important to repair any damage areas to a minimum of 200mm.
  • You should always install an edge when there is a boundary. A boundary that is removed can cause cracks in the resin bound surface.
  • Do you require edging detail Concrete kerbing or block should be installed 18mm above the base edge.
  • Make sure you clean the base thoroughly using a powerwash.
  • Before applying the resin bound surface to the surface, it must be completely dried. Resin and water do not mix.
