The SENTINEL® is suitable for fun DIY as well as commercial projects of almost 6 meter vertical retainer walling. A retainer wall need not be bland or require high maintenance. DSM retainers can add a stunning affect to your home and there is no upkeep needed.

The system is easily dry-stacked and locks easily into the block above to form an attractive retaining wall.
For high walls, geogrids are locked in every 2nd course of blocks to create a reinforced soil retaining wall structure.
