When the Load Gets Serious

We reach for besser block when the loading gets serious and a sleeper system would be working too hard. Core filled reinforced masonry gives our besser block retaining walls the highest structural capacity of anything we build in Wollongong, so they suit tall walls, driveway surcharge, pool zones and boundary walls doing structural duty.

Footings are poured to the engineer's specification with starter bars set to the block cores. Blockwork is laid true off that setout, reinforcement follows the schedule, and grouted cores lock the wall into one monolithic element. Finishes stay flexible: clean face block, bagged, rendered and painted, or clad in stone.

Site cuts are handled by our excavation and earthworks crew, and full landscaping sit behind every wall. To talk through your site with Retain by Theo, call 0417 661 224 for a free quote.

Built for Heavy Loads

Besser block is what we reach for when a wall has to carry serious load, sit hard on a boundary, or form part of a structure that will also be built on. It is a slower system to build and a far stronger one when it is done properly.

  • Reinforced concrete strip footings designed by an engineer
  • Vertical starter bars tied into the footing and lapped through the wall
  • Core-filled blockwork with horizontal reinforcement to specification
  • Drainage cell, aggregate and ag-line behind the full wall face
  • Rendered, bagged or face-block finish options
  • Suits boundary walls, garage and pool surrounds and split-level builds
