Work to turn an unstable sloping site in Poole, Dorset into a level area suitable for development has included the use of Secugrid geogrid products from Naue Geosynthetics.
Formerly a landfill site, the area measures some 350 x 150m. A 'cut and fill' operation was carried out to remove soil from the high part of the site, and placing it in the low section.
This demanded a solution for earth retention, which was provided by three examples from the firm's range. Spoil from the excavation at the rear of the site was used to create the correct level at the front. Some parts of the front of the site are now 5m higher than they once were, so a reinforced bank was needed.
The Naue Secugrid was selected because it was cost-effective in terms of purchase price and installation costs, and because it was capable of meeting the structural demands of the site.
Secugrid is a flat geogrid made from interlaced polymer bars, available in both uniaxial and biaxial orientations.
Construction of Sandhill Primary School in Barnsley has included products from Naue Geosynthetics for the foundation laying.
The company's Secugrid 40/40 Q6 was installed as the soil reinforcement element for a retaining wall, the infill material of which is lime stabilised soil. It is a flat geogrid manufactured from interlaced extruded PET or PP polymer bars.
Toulouse-Blagnac airstrip in France has Bentofix geosynthetic clay lines from Naue Geosynthetics. Preventing drainage water that is contaminated from polluting the ground water, the liners provided two geotextile layers to encapsulate a filling of natural sodium bentonite clay. In total some 40000m? of the product was installed with 24000m? of separation nonwoven Secutex 201 grk 3.
