Ultra-Lightweight Cellular Structure) made from polypropylene (PP, 60% recycled content), manufactured by Nidaplast (Hauts-de-France, France). On soft and compressible ground, it is used to limit settlement, stabilise unstable slopes and eliminate the driving force of slope failure by reducing the load applied to the foundation soil.<\/p><p>Technical specifications (2026 catalogue): dry unit weight 35 to 45 kg\/m\u00b3 (RA400\/500\/600), unchanged in the presence of water (95% void ratio, no buoyancy force). Short-term compressive strength 300 to 500 kPa (520 mm block). Long-term allowable bearing pressure 45 to 85 kPa (safety factor \u00d72, 50-year design life). For comparison: conventional granular fill 1,700\u20131,900 kg\/m\u00b3; EPS geofoam when wet approx. 100 kg\/m\u00b3.<\/p><p>Advantages on soft ground over conventional solutions: no prior soil treatment required, no buoyancy force under fluctuating water table, impervious to rodents (unlike EPS), installation rate 100 m\u00b3\/man\/day, suitable for rehabilitation projects.<\/p><p>Soft ground project references: RD990, Carlat (15, France), ~800 m\u00b3, RA500 in 3 layers, road rehabilitation after 13 years of unsuccessful repairs (cracking 2009, regrading 2012\/2017\/2020, RA solution 2022) \u2014 covering structure: crushed stone 20\/40 + geotextile + 10 cm RC slab + GNT 0\/31.5 + road pavement; Bayonne, Ametzondo zone, 780 m\u00b3, RA500, commercial zone access road on marshy ground, frequent vehicle traffic; A63 Motorway, Anglet. Validated in French national road construction guidelines and supported by documented installations since 1986.
