PermaBound UVR+ is a UV-stable two-part aliphatic resin bound gravel binder, manufactured to the very highest standards to ensure a perfect installation every time.
We’re the UK’s sole distributor of SoRoTo machinery. Manufacturers of the original forced action mixer, SoRoTo have a world-renowned reputation for tools and machinery for the construction industry
Our range of forced action mixers is perfect for resin bound gravel projects of any size. From a compact 40L up to the mammoth 300L, SoRoTo forced action mixers have been designed to withstand the harsh conditions of construction sites.
We pair the highest quality washed and kiln-dried aggregates, sand and polyurethane resin binder to offer you an enormous range of resin bound gravel kits
By combining washed and dried aggregates with a polyurethane binder, a resin bound surface is essentially gravel which has been encased to create a flat, smooth surface that allows surface water to permeate through it to the ground below.
Due to its durability, the ability to deal with surface water and the endless combinations of colours and textures, resin bound surfacing is popular with commercial and domestic environments.
A resin bound surface is most commonly used for domestic or commercial parking (including heavy vehicles), pathways, access routes, forecourts and standing areas. As a resin bound gravel installation is incredibly low-maintenance, with no raking, topping-up or rutting unlike loose gravel, it’s becoming the surface of choice.
As the majority of the material in a resin bound installation is stone, it’s incredibly durable, hardwearing and should last at the very least 20-25 years.
However, should issues develop below the resin bound layer such as settlement, or if the surface has been poorly installed, this can cause the upper resin bound surface to crumble, crack or fail entirely.
For these reasons, it’s very important to ensure that the resin bound aggregate surface is installed by an experienced, trained contractor.
Theoretically, yes. There’s nothing to stop anyone from installing resin bound for themselves or others, however, on one hand it looks incredibly easy to install but in fact there’s many factors which can cause an installation to fail.
When considering a resin bound driveway, path, patio or other resin aggregate surface it is recommended to solicit the services of a trained, experienced resin bound installer. Training courses are widely available on the installation methods and are usually inexpensive, but will often require some prior knowledge of groundworks or landscaping.
Simply put, no.
Aggregates need to be evenly and consistently coated with binder to prevent any dry spots within the mix. This isn’t possible with a traditional rotating drum mixer, as they’re too slow and do not agitate the mix enough. Dry spots in a resin bound mix will result in the surface crumbling in patches, a fault which is practically impossible to discreetly fix without relaying the complete surface.
A forced action mixer should be used which has several paddles inside the pan, combining the resin and aggregate components together much more quickly, evenly and consistently than a traditional mixer.
While they’re very similar and use almost identical components, the two surfaces are in fact quite different.
A resin bonded surface is usually much thinner (around 5-10mm) as the resin is spread out across the area and dried aggregate is scattered across and allowed to dry, similar to pebbledashing. The resin used in a bonded resin surface is a different polyurethane mix, often brown in colour and is not suitable for use in a resin bound project. It’s quicker and easier to install, has a more grippy texture but doesn’t offer permeability and is much less durable than a resin bound surface.
In resin bound surfacing, the resin and aggregates are mixed together and spread by trowel to create a completely flat, smooth surface which is usually between 15-20mm deep. This creates tiny gaps in the surface and allows water to pass through. As there’s very little texture to the upper surface, there’s much less to erode away and gravel is unlikely to be pulled away from the resin.
Devised by an experienced resin bound installer, the range of tools from The Resin Bull has been made specifically for installing resin aggregate blends.
When it comes to a resin bound gravel sub-base, it’s obvious that strength matters.
X-Grid is proven to withstand over 420 tonnes per m² of compression before being filled with gravel and weighs just over 5kg.
Don’t accept imitations, check it’s X-Grid.
X-Grid can be laid quickly by a single installer without the need for any specialist tools or equipment.
Designed to simply connect to the adjacent panels, each square metre connects through 108 integrally moulded nodes for stability and durability
With a void ratio of around 97%, X-Grid allows as much surface water to pass through, helping to reduce flood risks.
Concrete and tarmac can cause puddling between the different surface layers in a resin bound gravel build-up. This can result in cracking and disintegration of the upper surface.
Including aluminium edging profiles, primers and catalysts to help make your projects stand out
We have developed our resin bound calculator to help contractors work out the amount of materials needed for their project. Simply enter the area in m² of your project, select your desired thickness and contingency and the calculator will tell you how many kits you will require.
This calculator is offered for guidance only and is given without warranty or assurance as to its accuracy. Estimations given here should be verified by a suitably qualified professional and we cannot be held responsible for any overage or underage resulting from its use. It is good practice to over-order by a small amount, usually around 10%
