DSM incorporate Pre-sealing technology

WE ARE PROUD TO INTRODUCE OUR NEW DSM SENTINEL RETAINER ®.

DSM Sentinel Segmented Retainer Wall.

Sentinel 1

Prestige & Quality.
Near Vertical Walls.
Do It Yourself.
No Concrete Footings.
Flexible – 90° Corners, Steps, Straight or Curved Walls.
Commercial or Civil Walls to 6 Meters High.

The Sentinel Retainer wall system incorporates purpose made corner and capping units to provide classical reconstructed sandstone retaining walls. The unique design of the Sentinel wall system allows increased flexible over competing products. The Sentinel walls can be built almost vertical. Each block has only a 10mm setback, which allows all available space to be utilized to the maximum. Curved or straight walls can be erected and it is easy to build 90-degree corners with the purpose made corner block. A capping unit is adhered to the top course of the blocks to finish off the wall.

Sentinel blocks are suitable for retaining walls up to 6 metes high. The blocks are easily dry-stacked and their patented design locks into the block above to form an attractive structural retaining wall. For high walls, geogrids are locked in every 2nd course of blocks to create a reinforced soil retaining wall structure. (See design tables). To comply with most council requirements, please seek specific engineering advice for all walls over 1.5 metes high or for low surcharged walls carrying car traffic, etc.

Corners Corners are built by adhesively fixing the purpose made corner blocks to alternate courses. Allowances should be made for a 10mm step back per course. Lugs must be removed from the SENTINEL Blocks to ensure that the corner block fits evenly.	Curves For Convex curved walls simply knock the back fin off the block with a hammer. MINIMUM RADIUS Full Blocks: 1300mm Half Blocks: 650mm This is the min. radius of the top course. Adjust lower courses allowing for 10mm step back.	Steps Steps can be easily built using a combination of SENTINEL Blocks and capping units. The step risers are built with SENTINEL blocks. The capping units are then adhered to the top of the blocks to form the treads.

DSM Garden Retainer.

DSM, Garden retainers. We found a need in the South African market for a retainer that was firstly, a very much DIY product, would compliment a garden, did not require mortar, and was not more of an industrial bulky product. We found the answer with garden retainer, it can be used for walls of up to 6 courses high or as a garden edging. If you decide to change the appearance of your garden, simply unpack the blocks and move them.
