greenSand Semi-hardening Gradation 0-6mm

A climate-resistant semi-paving

The greenSand semi-paving of 0-6mm is the only semi-paving in the Netherlands that cleans up CO₂. The semi-paving is made of Olivine rich rock. The rock has a gray-green color and permanently removes CO₂ through weathering. Thanks to the high hook resistance and water permeability, you create paths that are wheelchair accessible and prevent unwanted puddles of water.

sustainable and climate resistant

Maintenance friendly

Due to the natural reaction of Olivine with rainwater, it deacidifies the soil and inhibits the growth of algae and weeds. As a result, the semi-paving retains its original color, in contrast to other semi-paving surfaces that turn green over time.

greenSand semi-hardening 0-6mm is suitable for:

Cycling and hiking trails

Create a nice stable layer that is permeable to water and wheelchair accessible.


Build paths

The ideal sustainable water-permeable paving for small and large projects.

In the city or in nature

Easy to apply and suitable for any project, regardless of location.

Frequently Asked Questions

What layer thickness do I need?

The layer thickness depends on the substrate. In general we recommend a layer thickness between 10-12 cm. After rolling, a layer of 6-7 cm remains. You will have to lay thicker on a softer surface than on a harder surface. It is also possible to first place a mixed granulate under the semi-paving.

How high are the shipping costs?

The shipping costs differ per purchase and are automatically calculated based on the weight during the checkout process. For large projects you can always request a quote using the form below.

What do you mean by low maintenance?

Due to the natural reaction of Olivine with rainwater, the soil is deacidified. This prevents the growth of algae, which means less maintenance compared to other handier semi-pavings.

How much CO₂ do I clean up?

The greatest profit is achieved by using greenSand as an alternative. Since other semi-pavings do not clean up CO₂ and only emit CO₂. The amount of CO₂ you clean up depends on the amount of weight you need for your project. You can assume 1 ton of CO₂ per 1 ton of Olivine. In reality, you will clean up more than 1 ton of CO₂ per ton of Olivine. However, we retain part of the CO₂ for our own account, due to transport, grinding, etc.

What makes the semi-paving permeable to water?

In the Netherlands we have been suffering from heavy rain showers lately. Our semi-paved surfaces have an angular structure that makes them very permeable to water. In addition, this also ensures good hook resistance. This makes the greenSand semi-paving an ideal solution for bicycle and walking paths without puddles.

Where can I find the technical documentation?

All relevant technical documentation can be found in our downloadable product sheets on this page.

"Let the earth help us save the earth"

Every kilo of greenSand clears up 1 kilo of CO₂

The mineral Olivine weathers (rusts) with the CO₂ in the rainwater. It has been proven in the lab that 1kg of greenSand Olivine captures 1kg of CO₂. However, we are convinced that it goes even faster in real nature. By using greenSand Olivine as a replacement in as many applications as possible worldwide, we can permanently capture a large part of the CO₂ surplus in a natural way. Will you also contribute?
