Resin Surfacing

What is the difference between resin bound and resin bonded?

expand

The main differences are thickness that the systems are applied, application method, appearance and aggregates used.

Thickness - A resin bound system is applied between 12-25mm thick. A resin bonded system is applied as a thin veneer of resin and then aggregate on top approximately 5mm thick depending on aggregate size.

Application- Resin Bound is trowel applied. Resin Bonded systems is where the resin is applied and then the aggregate is scattered on top of the wet resin.

Appearance - Resin Bound Systems are fairly flat and even. Resin Bonded Systems are rough in texture taking on the texture and appearance of the aggregate as this sits on top of the resin.

Aggregates- Resin Bound systems use a combination of 2 or more grades of aggregates that are different sizes (2-5mm and 1-3mm). Resin Bonded systems normally use one size grade of aggregate such as a 1-3mm.

Which Paving System should I use for my driveway resin bonded or Resin Bound?

expand

It really depends on the appearance that you prefer, your budget and whether it is a new driveway that falls under the SUDS legislation.

In some cases though one system may be more suitable for your particular driveway. Your contractor will be able to advise you on the best system for your project.

The Adtex Activator has separated?

expand

Sometimes in the colder months the raw materials that are contained within the activator may separate, this is a common problem with these types of materials. To thaw the activator and solve the separation problem please gradually warm the activator. Please note simply shaking the activator will not solve the problem. The separate occurs where the activator drops below zero.

Resin Bound Paving Systems - GeoPave

Is GeoPave environmentally friendly?

expand

Yes - GeoPave is a green environmentally friendly product as it has been formulated using biomass materials and is solvent and odour free.

Why is Adbruf's Resin better than other resins on the market?

expand

Our Adbruf's GeoPave resin is based on their sister product Coldgrip resin that has been re-developed specially for use in a resin bound system. Coldgrip is used for high friction surfacing for roads and so is incredibly durable. Coldgrip has been BBA approved and has a high certificate value. GeoPave is actually a hybrid polyurethane that has has thermoplastic properties making it more flexible then other polyurethane resins. GeoPave is also moisture tolerant unlike other resins.

What is GeoPave?

expand

GeoPave is a resin bound paving system that comprises of a two component resin and aggregates.

When I buy GeoPave what will i get?

expand

GeoPave is actually the resin part that makes up the system. GeoPave resin is available in standard or UV resistant variants. You will recieve two containers that make up the resin component of the system. If you are using GeoPave UVR you will also require the addition of our VA5 Catalyst. You will also need to buy the appropriate aggregates.

Aggregates can be bought from Adbruf or sourced else where. Ensure that you read all of the information regarding GeoPave prior to purchasing and installing the system.

Where can GeoPave be used?

expand

GeoPave is suitable for for driveways, estate roads, parking areas, footpaths, courtyards, patios, conservatories, garden design, playgrounds, swimming pool surrounds, disabled access ramps, roof terraces, balconies and as part of a permeable paving SUDS solution.

It can also be installed internally, making it the perfect choice for large scale projects consisting of internal atria and external courtyards.

What is the GeoPave resin made from?

expand

The resin is supplied as a two component pack, that will be combined during the installation process. The resin is a unique hybrid polyurethane, formulated using biomass materials. It is therefore an environmentally, eco-friendly product that is both odour and solvent free. There are two GeoPave variants; GeoPave Standard and GeoPave UV Resistant.

Why is a Polyurethane resin better than an epoxy Resin?

expand

Polyurethanes are Quicker curing, especially at lower temperatures, are less affected by extremes of temperature and offer greater flexibility. They are also less affected by age embrittlement and less prone to debonding. Epoxies are generally brittle in nature.

Is GeoPave UV resistant?

expand

Yes - we manufacture two GeoPave variant GeoPave Standard and GeoPave UVR. GeoPave UVR is an aliphatic polyurethane system which is highly light stable and is exceptionally resistant to discolouration after exposure to light. It is best suited for use with light coloured aggregates or other aggregates where colour stability is a key requirement.

What is the GeoPave pack size?

expand

We supply two different pack sizes. A standard size and a tree pit size. The UVR and Standard variants are both supplied in the same size. Standard packs consists of two components, comprising a base and an activator component in sealed containers.

GeoPave is currently supplied in a 6.5 kg pack size designed for a typical 100 kg aggregate blend. For Tree Pits, smaller packs are available which contain 4 kg of total resin binder.

How much aggregate will we need for one pack of GeoPave resin?

expand

Typically 100kg is required for one 6.5kg pack. Aggregate is normally sold in 25kg bags, therefore one pack requires 4 bags of aggregate.

What thickness do I install GeoPave?

expand

It really depends on the end use of the installation but we recommend:

12mm - if the installation is to be used by pedestrians only or the sub base is strong and sound and can withstand the expected loads.

18mm - for a standard driveway - with light to medium traffic

25mm - for an installation area that is expected to withstand heavy vehicles

If you are unsure as to how thick you should install the system please contact us.

What aggregate can I use with GeoPave?

expand

We recommend that you use a mix two grades of aggregates as this is what will give the system its cohesive strength. We usually recommend a combination of at least two grades of aggregate normally a 1-3mm and a 2-5mm. we have a range of mixes available - see our GeoPave page on this site.

Aggregate must always be clean, dry, contamination and dust free prior to use within a resin bound system.

What can GeoPave be applied to?

expand

GeoPave is suitable for use over typically encountered load bearing substrates such as asphalt and concrete. I can also be applied to wood and paving slabs however there are specialist application instructions for these substrates - contact us for more information.

Does it matter which resin I use with each mix?

expand

Yes - GeoPave UVR is a clear resin that is more suitable on Adbruf's light coloured aggregates and lighter mixes or other aggregates where colour stability is a key requirement.

GeoPave Standard resin is a neutral amber colour and is particularly suitable for buff, yellow, red and brown aggregates. Some initial darkening of the resin binder may occur through the effects of sunlight in the early life of the finished system. This slight darkening can often be complimentary to the aggregates used.

Why is GeoPave SUDS Compliant?

expand

GeoPave is permeable as it has many voids across its entire surface area, making it more effective than other SUDS compliant systems. The water is able to soak through the surface, filtering through the voids and drain away.

The sub base must also be SUDS compliant therefore we have a specific SUDS base build up specification detailing the requirements.

Can GeoPave be used for Tree Pits?

expand

Yes - GeoPave is an effective alternative to open tree pits as it is permeable and so able to feed the tree's roots, flat and even minimising the collection of litter and easy to maintain.

How do I Install GeoPave?

expand

GeoPave should be installed by a specialist contractor and we are happy to recommend a contractor in your area. Just complete our find a contactor form within the contact us section.

If you are a contractor that wishes to add resin paving systems to you portfolio we run training days periodically - check out our training section.

In simple terms however, the two resin components are first mixed together using a drill and paddle. The resultant resin is then poured into a forced action mixer that has be pre-charged with the selected aggregate. The resin and aggregate are then mixed until all of the aggregate has been fully coated. This mix is then transported to the application area and roughly distributed. Finally it is compacted and finished using a trowel. Please view our GeoPave Application and marketing video guides for visual instruction.

How long does it take for GeoPave to cure?

expand

Initial set @ 20°C - 40 minutes Full cure in bound system @ 20°C - 24 hours However if you are using our GeoPave UVR system, you will require the addition of our VA5 Catalyst which will alter the curing times. Contact us for more information.

What is the Spread Rate of GeoPave?

expand

Spread Rate (approx. per 100 kg of typical aggregate, assuming bulk density of 1.67) 12 mm surface depth 4.99 m² 18 mm surface depth 3.32 m² 25 mm surface depth 2.39 m²

What tools are required for a GeoPave application?

expand

Equipment required for a successful GeoPave installation is relatively inexpensive and comprises – a broom and shovel to prepare the surface, polythene sheet and masking tape to protect the work and adjacent areas, gloves and goggles for personal protection, a drill, paddle, and a mixer to combine the resin with the selected aggregates, a wheelbarrow to transport the mix and a squeegee, trowel and white spirit to apply and finish the surface.

What Type of Mixer is required for a GeoPave application?

expand

We recommend that you use a forced action mixer for best results.

How do I clean the equipment after using them with GeoPave?

expand

We recommend that you use our Cleaning Solvent with a clean cloth.

What temperatures can GeoPave be applied at?

expand

The minimum temperature that GeoPave can be applied at is 5°C. It is easier to apply GeoPave if the aggregate and resin is kept warm on a colder day. If GeoPave is to be applied on a hot day it is best laid early morning or late afternoon as the resin will become thin in excess heat and could potentially drain away.

Is a primer required prior to GeoPave application?

expand

On good surfaces, a primer is not required, but on a friable or dusty surface then we do recommend that the surface is thoroughly brushed and primer is applied. our Primer C is an effective primer.

Is GeoPave Hazardous?

expand

GeoPave Standard and GeoPave UVR are not hazardous, however catalyst VA5 is hazardous. We do recommend that correct safety gloves, googles and boots are worn.

The GeoPave Activator has separated?

expand

Sometimes in the colder months the raw materials that are contained within the activator may separate, this is a common problem with these types of materials.

To thaw the activator and solve the separation problem please gradually warm the activator. Please note simply shaking the activator will not solve the problem.

The separate occurs where the activator drops below zero.

A resin bound surfacing system forms a a layer between 12 - 25mm thick dependent on the end use of the surface. http://t.co/YS0Lf...
