British Library Update
Our joiners are currently setting up the shuttering for the new pedestrian grasscrete footpath, which extends from the East Elevation around to the North Elevation.
This innovative footpath marks a first-time application for this specific product and forms a key component of the Sustainable Drainage System (SuDS) previously installed by HCE at the British Library. To ensure the permeable system works efficiently and effectively, it is being constructed in precise, distinct layers. The foundation begins with a Terram geotextile membrane to separate the soil strata and control water retention, followed by a gravel bed surrounding the land drain.
Next, a specialised, permeable solid concrete material known as hydraulically bound coarse is applied, topped with a thin bedding layer of sand. Finally, the main grasscrete paving is installed on top, reinforced with an A252 structural mesh to guarantee long-term strength and stability.
