 Foundation over cavities

In order to minimise the potential of sudden settlements which would be a danger for the public traffic, preventive measures using high-strength TenCate geosynthetics are recommended. In the case of a sudden damage of the subsurface, the geosynthetic acts as a membrane keeping the road or railway structure intact until further repair measures can be undertaken.

In case of critical deformation restrictions or in applications  where survey is required, TenCate GeoDetect® can be installed in order to monitor the reinforced structure. TenCate GeoDetect® measures and follows the strain in soil and enables transmission of a warning signal as soon as its elongation reaches a preset limit.

Pile foundation

In order to guarantee the stability of embankments over weak subgrade, piles are very often used. Geosynthetic reinforced base courses transfer the loads from the embankment to the piles, helping to reduce the required number of piles, thus reducing costs.

In case of critical deformation restrictions or in applications  where survey is required, TenCate GeoDetect® can be installed in order to monitor the reinforced structure. Geodetect measures and follows the strain in soil and enables transmission of a warning signal as soon as its elongation reaches a preset limit.

Embankments on weak subgrade

TenCate geosynthetics are placed at the base of embankments to provide short and long term stability and limit differential settlement. The geosynthetic is placed directly on the soft foundation, prior to the placement of the embankment fill.
TenCate Geosynthetics facilitate the construction of a working platform and allow construction of  higher embankments and steeper embankment side slopes.
