Explained
Overview
Capping Beams are structural elements made of steel and concrete that ties all the piling together, creates the foundation for the slabs and helps to hold the earth and neighbouring houses back. Capping Beams sits along the top of the piling to strengthen it all. We deliver the Capping Beam on site to install in position. The rear face of the capping beam is formed to the set-out lines and when ready concrete is sprayed to the Capping Beam. The Capping Beams can be done: In situ using a mould with plywood and Steel, where most of the strengths comes from Boparai Concreting Piling uses top to bottom concrete spraying method, so the concrete is only sprayed ¾ of the width of the Capping Beam leaving the front ¼ exposed. This way the shortcrete wall is sprayed continuously from top to bottom, eliminating a construction joints on the wall face.
Purpose of Shotcrete Walls
- Used to tie all the piling together as well as creates the foundation for the slabs and helps to hold the earth and neighbouring houses back
- Capping Beams sits along the top of the piling to strengthen it all
The Process
- All reinforcement for piling is manufactured off-site and it is delivered prior commencement of the drilling holes.
- Installing a bored pile starts with drilling a vertical hole into the soil, using a bored piling machine. Piles can be drilled to a depth of up to 60 meters and a diameter of up to 2.4 meters.
- Once the desired depth is achieved reinforcement cages (bound structures of special rod and reinforcing elements) are placed in the pier.
- The cages – structures of special rod and reinforcement elements, are used for reinforcement.
Roles and Responsibilities: Shotcrete Walls
- Advise the starter bar size (as specified by the engineer)
- Ordering of capping beam reinforcement
- Positioning of the capping beam to the set out lines (as per specifications by the surveyor)
- Spraying of concrete onto the capping beam
Client:
- Work with surveyor re capping beam setout lines (as required)
- Submit plans

Bored Piles
Bored piles provide strong deep foundations, ideal for heavy structures and challenging soil conditions.
Capping Beams
Capping beams provide structural support, distribute loads evenly, and connect adjacent piles for foundation stability.
