Using GRC planters with lowered adjoining internal walls

Satu Bumi’s raised garden bed formwork solution is based on the off-site manufacture of precast GRC planters with lowered internal walls that are conveniently joined together on-site. After installation, the result provides the appearance of a continuous single garden bed as opposed to a series of individual planters placed adjacent to each other.

The result of using lowered internal walls is clearly shown when you click on the image to the right where a very large planter area appears to be one planter made from on-site formwork but is actually made up of a significant number of precast planters manufactured off-site and assembled on site.

A render of the whole installation is prepared to clearly show how the final GRC planter installation will look. Shop drawings are then prepared for each of the GRC elements for the project that include lowered internal walls, lifting lugs, drainage holes and connecting holes or ferrules. The shop drawings also include an installation roadmap for the installation team that shows the exact position of each of the pre-numbered GRC elements, and installation instructions on how to connect and waterproof the adjoining lowered walls.

Explanation of how lowered walls on planters can work

Using precast GRC formwork benches as retaining walls

Satu Bumi’s use of GRC bench seat retaining walls as the basis for raised garden planter beds is based on the off-site manufacture of the precast GRC benches that are then installed, joined, and waterproofed on-site.

Precast GRC retaining wall seating can be efficiently installed on slab floors without the practical difficulties associated with the blockwork equivalent.

Explanation of how it works:

A render of the whole installation is prepared to clearly show how the final GRC retaining walls installation will look. Shop drawings are then prepared for each of the GRC elements for the project that include any relevant fixings or ferrules. The shop drawings also include an installation roadmap for the installation team that shows the exact position of each of the pre-numbered GRC elements. The actual fixing and waterproofing of the voids created by the retaining walls would generally be the responsibility of the installation team.
