Gardenwall Soft Split Portstone
Soft Split Portstone Retaining Wall is a part of the Gardenwall series by National Masonry. The single block retaining wall system can be constructed up to 1m high, in a curved or straight wall, without the need for caps. It's called "Soft Split" because the imitation "split" texture on the face is scored into the concrete while it is still soft, before the concrete cures. The interlocking lip at the back of the block allows for easy interlocking, mortarless construction. Once the footing is dug and prepared properly, and the first course laid, it's a simple matter of stacking the rest of the blocks to the required height, backfilling with drainage gravel as you go, and gluing down the top course with construction adhesive.
