Bastida Multi-Angle Column - Corners, Curves and Sloping Ground

Bastida Multi-Angle Column: the post that turns with the plot

Almost no plot is a perfect rectangle: there are corners that aren't 90º, boundaries that kink, and sloping ground. The Bastida column is built for exactly that: its outer toothed profile lets you build the enclosure at 45º, 90º, 135º, 180º and 225º with no special pieces or cutting, and it's stacked at a rate of 6 pieces per metre of height.

✅ Key advantages

  • Genuinely multi-angle: the same post works as a straight-run column (180º), a corner column (90º), a gentle kink (135º or 45º), and a return (225º). No need to order different references for corners.
  • Non-straight layouts: chaining small turns lets you follow curved boundaries, roundabouts and path edges, something a fence of rigid 2 m panels can't do.
  • Sloping ground: because the fence is built in 12.5 cm courses and the column rises 17.1 cm at a time, the enclosure steps down the slope instead of leaving a growing gap underneath.
  • Self-stacking and self-locating: tongue-and-groove between pieces, with the tongue facing up. There's no need to set out each post separately: the column goes up at the same time as the panels.
  • From ground level or on a wall: it starts from the foundation or is built on top of a wall already capped with wall coping, to add height without infilling.
  • Hollow and reinforceable: the Ø 13.5 cm interior houses the vertical bar and the fill mortar, so the post ends up reinforced and monolithic.

🏗️ Recommended applications

  • Corners and kinks in plot or house enclosures.
  • Fencing on sloping ground, stepping the enclosure down.
  • Curved boundaries, entrance roundabouts and path edges.
  • Building up existing block walls.
  • Dividing zones within the same property: pool, vegetable garden, play area.

🧩 This column is one piece of a system

The column alone doesn't close anything off: it's the post of a four-piece modular enclosure that's installed together. You'll also need:

  • The Bastida enclosure panels (75 × 11 × 12.5 cm, straight or curved): fill the bay between columns. Each panel covers 75 cm of span and 12.5 cm of height per course, with a coverage of 10.70 pieces per m².
  • The Bastida panel coping (50 × 20 × 4 cm): caps the last panel course and reinforces it. Its starter piece fits into this column's toothed profile.
  • The Bastida column cap (Ø 28 × 4 cm): the cap that closes the post at the top and keeps water out of the mortar fill.

How many columns and panels you need. A 3.00 m bay between columns is closed with 4 panels per course, and a 3.75 m one with 5 panels per course. Stacking 15 panel courses reaches 1.88 m in height with bays of up to 3.75 m; to go up to 2.38 m (19 courses), reduce the bay to 3.00 m. For a 1.88 m fence, allow 11 column pieces per post (11 × 17.1 = 1.88 m).

🧰 Installation

  1. Foundation. Dig a trench 35 cm wide by 50 cm deep along the whole run. Place 4 reinforcement bars of 8 mm for the footing, and anchor to them the vertical 8 mm bars that will run up inside each column.
  2. Concreting. Fill with M-80 grey mortar (minimum 380 kg/m³, 1 part cement to 4 parts sand), screed level with a straightedge, water it, and let it dry for at least 48 hours before touching anything.
  3. First piece. Wet the pieces before installing them. Bed the first column piece level and plumb in both directions: it governs the whole column.
  4. Building up together. Build up columns and panels at the same time, always with the tongue of the tongue-and-groove facing up, checking alignment and plumb with a straightedge at every course.
  5. Filling the column. Every 6 pieces, fill the interior with lean M-40 mortar, well spread out. On the last piece, screed it right to the top to stop the mortar shrinking as it dries and leaving a hollow where water can collect.
  6. Curing and capping. The next day, water the work for 2 days and let it dry for a further 48 hours. Then fit the panel copings, cap each column with its cap, and treat the surface with a water repellent.

💡 Professional tip: what ruins these fences is skipping the foundation or the reinforcement. With a trench under 50 cm deep, or without the vertical bars anchored to the footing, the column is just a stack of 6 kg pieces resting on each other: the first strong gust of wind or a knock from a car reversing opens it at a joint and brings down the panel run hanging off it. The same happens if you skip the mortar fill every 6 pieces. And plumb the first piece obsessively: a 2 mm error at the base becomes 2 cm at the top, the panels stop fitting cleanly into the toothed profile, and the coping no longer sits flat. Set out the whole column line with string before concreting, measuring the real bays, because once the footing has set the bars won't move.
