If you have just purchased a property, you may need to refresh your paving!
Old terracotta, cracked concrete, pavers and tiles – ceramic, travertine and porcelain..StoneSet can resurface them all.
Driveways and pathways can remain functional well past the signs of the the first cracks or discolouring. Much of the older hard surfaces we overlay with StoneSet has seen better days! Quite often the surfaces we overlay has cracks, dips and is uneven.
After all, LDC Paving says that traditional asphalt can last for twenty, or even thirty, years before it needs to be replaced. While that is true, it’s also true that traditional asphalt can begin to show cracks within a few years of its initial installation.
Because hard surfaces such as concrete are so durable, they are often neglected and a last renovation on the list when it comes to maintaining your property.
Not just an aesthetic issue, trip hazards can form as a result of significant wear, including erosion and cracking.
“Cracks tend to travel in solid rigid bodies, leading to more water ingress and destabilisation of the cement based adhesive or render.”
Under Pressure..How Cracks Form
Over time, there is significant wear on all hard surfaces such as concrete and outdoor paving.
Cracks can form in concrete over time for various reasons;
- Movement down – Water causes erosion and destabilisation of the sub-base
- Movement up – Tree roots are a classic example, also concrete cancer cracking
- Heavy Impacts – Cracks from when a hard edge with weight falls on paving.
- Erosion – Water ingress from rain or runoff, i.e. a pool.
As the image shows below, cement cracks often travel through a solid mass of concrete with overlaid aggregate like pebble. Cracks tend to travel in solid rigid bodies, leading to more water ingress and destabilisation of the cement based adhesive or render. An example of cracks travelling in a rigid body of cement;
Stoneset’s Polyurethane Flexes
Resin bound stone can with stand this cracking as there is more flexibility in the multiple number of bonds that form between the stone. Flexibility is achieved as some bonds can break whilst keeping the surface appearance similar.
StoneSet use an Alipathic Polyurethane which is a non-aromatic cross linked carbon polymer chain. Unlike a solid cementitious binding agent like concrete, these thousands of polyurethane bonds allow the stone to surface to flex under pressure.
Unlike pavers being a solid mass of rigid hard material, StoneSets’ strength and flexibility ensure that your porous pavement won’t crack like a rigid surface such as concrete.
In fact, porous pavement is so flexible that the same holds true for tree roots! Your StoneSet won’t crack like a sidewalk eventually would if placed next to a growing tree.
NOTE: The below Video is a mix of Stone and Rubber and demonstrates the flexibility that StoneSet can achieve. The standard StoneSet resin bound stone if flexible however to a lesser extent without incorporating rubber.
Avoid Cracks and Erosion
Primarily wear is via constant exposure to UV radiation from the sun. This weakens the chemical bonds that hold synthetic materials together.
Exterior house paint is a good example – Exterior paints are formulated to do their best to withstand UV, but no paint in constant sun exposure can retain its colour and integrity beyond 5 years.
The surface level of cement, similarly suffers degradation from constant UV exposure. Cement exposed to the sun becomes brittle over time and susceptible to further wear.
Typical wear process on cement;
SUN UV ON cement
top layer becomes Brittle
Rain, Puddles & friction (car tires)
Erosion Wear and loose pebble
Primarily this manifests where there is also water erosion. A mix of friction and pressure from foot and vehicle traffic. A well worn path is a great example how these three factors come together to create a very obvious case of wear on hard surfaces
This is made worse by exposure to Salt and Chlorinated water if your paving is nearby a pool. Repeated exposure to these chemicals also work to weaken the bonds in cement over time, Very slowly, the top layer of cementitious material becomes more brittle.
Because the paving stones can flex, they don’t crack as easily with seasonal temperature changes and they can handle high traffic. StoneSet’s polyurethane resin can withstand it all. With a 10-year guarantee, StoneSet offers an unbeatable paving solution for your home.
Typical wear with StoneSet involves;
SUN UV hits top of stone (not resin)
Stone absorbs UV
Porous – water doesn’t pool
No degredation of stoneset
porous surfaces avoid further wear
Porosity means a surface that is non-slip, no puddles, no erosion, no attracting bugs / mosquitos breeding etc.
Waterproof Polyurethane and Stone – Being as simple as stone mixed with polyurethane resin, StoneSet’s resin bound natural stone surface has greater durability as pool surround paving than other options. Why?
Stone is Waterproof and doesn’t degrade with water exposure.
Polyurethane is waterproof and doesn’t degrade with water exposure. Whilst polyurethane does degrade with UV exposure, the sun’s rays don’t reach the binding polyurethane in StoneSet that is hidden BELOW the stone surface.
All the above pool surround surfaces are rigid and/or are susceptible to water ingress and therefore wear over 10 – 20 years.
StoneSet’s blend of stone and polyurethane resin does a far better job of conserving and preserving it than concrete, due to its permeable nature.
