Laying Resin Bound

Avoiding common problems when laying resin bound surfacing

Resin bound surfacing has gained popularity in recent years as a durable and visually appealing option for driveways, pathways, and outdoor spaces.

Its smooth and seamless finish, along with a variety of colour options, make it a favoured choice among homeowners and property developers alike. However, like any construction project, there are potential pitfalls that can arise if not properly addressed. In this article, we will delve into the crucial aspects of laying resin bound surfacing and explore the problems to avoid, ensuring a successful and long-lasting installation.

Unexpected Rain and Curing Too Quickly

One of the primary problems to avoid when laying resin bound surfacing is the challenge posed by unexpected rain. Rainwater can disrupt the curing process, leading to a weakened bond between the resin and the aggregate. To counter this issue, it’s essential to monitor weather forecasts and plan installations during periods of dry weather. In cases where rain is anticipated, protective measures such as covering the site with waterproof materials should be taken.

Moreover, the opposite extreme – curing too quickly – can also be detrimental. Rapid curing might result in a weaker overall structure due to inadequate bonding. To mitigate this, adjust the curing process by considering factors such as temperature, humidity, and the choice of curing agent. Ensuring optimal curing conditions will contribute to the longevity of the resin bound surface.

Limited aggregate and Surface Detachment

Insufficient aggregate content in the mixture can lead to inadequate coverage and ultimately result in surface detachment. This problem is often caused by an inaccurate mix ratio of resin to aggregate. To overcome this issue, it’s important to stress the significance of following manufacturer guidelines for the correct mix proportions. Proper mixing ensures a strong bond between the resin and aggregate, preventing potential surface detachment issues down the line.

Walking on the Surface Prematurely

Impatience can lead to one of the most common problems encountered during resin bound surfacing installation – walking on the surface before it’s fully cured. When users search for solutions to this problem, your article can provide insights on the importance of allowing the surface ample time to set. Walking on the surface too soon can mar the finish and compromise the integrity of the installation. Emphasizing the need for patience during this phase is crucial for a successful outcome – we think the best way to avoid this is to tape off finished sections so anyone unaware that the surface is still curing will walk around it.

Consistent Mix for Uniform Appearance

Achieving a uniform appearance across the entire surface is vital for aesthetic appeal. A problem that can arise when laying resin bound surfacing is an inconsistent mix, resulting in variations in colour and texture. To prevent this issue, stress the importance of thoroughly and consistently mixing the resin and aggregate. Additionally, promoting the use of calibrated mixing equipment can help ensure an even distribution of materials, resulting in a visually pleasing and cohesive finish. We find the easiest solution is to have one person do the mixing for the entire job, this will ensure consistent mixes throughout the application process.

Tree Roots and Surface Disruption

The intrusion of tree roots is a potential problem that can lead to surface disruption over time. When roots grow beneath the surface, they can exert pressure that causes cracks and unevenness. This issue can be avoided in a couple of ways, such as installing root barriers or choosing a suitable location that minimises the impact of tree roots.

Iron Spotting and Surface Staining

Iron spotting refers to the appearance of rust-like stains on the resin bound surface. These stains can be caused by the presence of iron particles within the aggregate or the use of iron-rich tools during installation. It is recommended to select iron-free aggregates (which we supply!) and use non-ferrous tools (which we also supply!) to prevent unsightly stains.

Surface Clouding and Hazing

Surface clouding or hazing occurs when the resin is improperly mixed or applied, resulting in a cloudy or dull appearance. The significance of proper mixing techniques, as well as the use of high-quality resin and aggregate, to prevent surface clouding and ensure a visually appealing result is of the up-most importance to avoid clouding and/or hazing.

Loose Stone and Inadequate Compaction

A common problem that can affect the longevity of a resin bound surface is the presence of loose stones or inadequate compaction. This issue can lead to an uneven surface and premature wear. It is important to ensure thorough compaction during installation, a process known as ‘trowelling’. Make sure adequate resin & aggregate is used to the depth specified by the client, and don’t leave any gaps!

In conclusion, resin bound surfacing offers a range of benefits, from its aesthetic appeal to its durability. However, to ensure a successful installation, it’s crucial to be aware of and address the potential problems that can arise. By avoiding these issues property owners and contractors can create resilient and visually appealing resin bound surfaces that stand the test of time. Remember to prioritize proper planning, adherence to manufacturer guidelines, and attention to detail to achieve optimal results and a happy customer!
