Any temporary or permanent unpaved surface subject to trafficking needs a correctly engineered, but economic design, especially when we talk about weak subgrade conditions. This ensures optimum use of resources and provides a reasonably smooth surface, with tyre loads distributed evenly to prevent rutting and meet the required design life.
Our design department has many years’ experience in designing unpaved roads, car parks and windfarm access roads over very weak CBR subgrades. We are able to offer cost-benefit advice on which solution is best suited to your project, utilising one – or a combination of – geogrids, geocells and geotextiles that deliver a lower carbon footprint.
