A 12 000m² warehouse for storage of thousands of tons of soya had to be built on of low bearing, silty, fine hydraulic fills which are up to 4m in depth at the Durban Harbour area. These hydraulic fills are underlain by silty sand horizons which are interspersed by sandy clay and sandy clayey silts, which vary from 2m to about 20m in thickness. Calcareous sandstone, soft shale and siltstones were also found at depths of between 25-27m below ground. The water table was at 1. 6m below natural ground. The client needed the structure to be finished as quickly as possible. The challenge was to provide a suitable foundation to carry such huge loads, on such poor founding conditions, in the quickest time.

Embung Aji Raden was planned to be constructed above soft soil. The existence of soft soil has the potential to cause non-uniform settlement, and if not prevented immediately will cause long-term problems in the stability of the embankment above. Thus, basal reinforcement is needed below the embankment to distribute embankment load to the soil and to reduce differential settlement potential.

The access road of a new retail center has been planned in Mechelen, Belgium, to let customers easily drive to the new shopping mall. Initially, the retaining wall for the ramp leading to the bridge abutment had been planned as a concrete L-retaining wall, but, thanks to the technical support of Maccaferri, the design has been changed in favour of 530 sqm MacRes System with 12. 000 lm of ParaWeb reinforcement. Due to the bad foundation soil characteristics, the contractor asked Maccaferri´s support also for the calculation and delivery of 1. 100 sqm of ParaLink 950 as basal reinforcement over piles. Smooth standard panels have been chosen.
