resin bonded comparison against resin bound installation
We are always astounded by the statements of inexperienced resin installers who don’t take the time to understand ( or know) what they are saying about their products. When they provide a resin bonded comparison against resin bound comparison installation it is evident they don’t know some of the basic differences
- Incorrect “Excavation of existing tarmac or concrete surfaces to a depth of 350mm required for resin bonded and resin bound installations” Not applicable to resin bonded installations. In fact doing this for a resin aggregate driveway, path or patio can create unnecessary cost and work.
- Incorrect resin bonded comparison against resin bound comparison installation “crushed concrete is required for the stability and drainage” Not applicable for resin bonded installations a solid concrete, tarmac or imprinted concrete is required.
- Incorrect not the correct process for resin bonded installations “20mm of the chosen resin trowelled on ”
- Incorrrect resin bonded comparison against resin bound comparison installation if “permeable” quoted as a benefit to bonded and bound – only applies to resin bound installations
- “Hardwearing, durable, long lasting and weed free” No surface is weed free however resin bonded stone is as near as you can get
- “encapsulated natural aggregate surface with a smooth trowelled finish” Only resin bound stone is encapsulated
Benefits of a resin bonded comparison against resin bound comparison installation should highlight the different merits and different purposes of resin bound and resin bonded installations
Porosity or Permeability
Only resin bound installations are permeable. However permeability or impermeability is not an issue, managing run off water is the concern
Suds compliant – SuDS principles
“Sustainable drainage is a departure from the traditional approach to draining sites. There are some key principles that influence the planning and design process enabling SuDS to mimic natural drainage by:
- storing runoff and releasing it slowly (attenuation)
- allowing water to soak into the ground (infiltration)
- Slowly transporting (conveying) water on the surface
- filtering out pollutants
- allowing sediments to settle out by controlling the flow of the water”
The simple installation of resin bonded stone provides this due to the specialist aggregate particle sitting proud of the resin as opposed to the resin bound installations needing to add an anti slip element to the mix as the particles are encapsulated.
Weed free (or as it should say virtually weed freed)
This is a quality of resin bonded stone installations as opposed to resin bound. Why? Because if water cannot get through (impermeable therefore no water can get through and no seeds can embed) . Resin bound installations by their very nature allow the ingress of water, so if water can get through then so can weeds.
Resin bound installations by their very nature offer the permeability. This means maintenance is required to ensure the permeability is maintained.
Primarily resin bonded installations are designed and installed to resurface and protect existing surfaces. Existing being the key word. Concrete and tarmac have been and still are used as a main structure for driveways, paths and patios. Over periods of time, good installations of concrete tarmac or imprinted concrete can last for years. If you think about what structure is in place for most properties – footings – concrete. Then this proves the durability of a substrate. If it is not broke don’t fix it. Hence the resurfacing.
