Bastida Enclosure Panel - Privacy with Air and Water Flow

Bastida Enclosure Panel: the piece that fills the gap

Enclosing a plot often forces you to choose between seeing out and being seen, or building a solid wall that blocks the air and leaves water pooling at the base. The Bastida panel solves both problems: its geometry blocks the view from outside while still letting air circulate and water drain away, with a yield of 10.70 pieces per square metre of enclosure.

✅ Main advantages

• Privacy without a solid wall: the interior can't be seen from outside, while light comes in and air flows through from the inside.
• Doesn't act as a sail: because it lets the wind through, the enclosure is under far less stress than a solid fence of the same height.
• No pooling water: rainwater passes through the panel instead of collecting at the base.
• Two finished faces: the panel is finished on the front and the back, so there is no ugly side to hide from your neighbour.
• Two designs that can be combined: the straight panel gives a clean line, while the curved one creates an interplay of light and shadow that changes throughout the day. They can be alternated within the same section.
• Guided dry assembly: the panels interlock vertically with each other and sit in the notched profile of the column, with no formwork or welding.

🏗️ Recommended applications

• Enclosure of plots, villas and single-family homes.
• Separation between neighbours and division of areas within the same property.
• Raising an existing block wall to gain height without filling it solid.
• Concealing utility areas: septic tank, bins, clothes line, air conditioning unit.
• Enclosure of swimming pools, sports courts and play areas.

🧩 This panel is one piece of a system

The panel cannot stand on its own: it is part of a modular enclosure made up of four pieces that are assembled together. To build the fence you will also need:

• The Bastida multi-angle column (Ø 22 × 17.1 cm): this is the post. Pieces are stacked one on top of another at a rate of 6 pieces per metre of height, and its notched profile receives the ends of the panels. It is multi-angle, so it rotates to 45º, 90º, 135º, 180º and 225º to handle corners, changes of direction and sloping ground.
• The Bastida panel cap (50 × 20 × 4 cm): it crowns the last course of panels, reinforces it and diverts water with its drip edge.
• The Bastida column cap (Ø 28 × 4 cm): it covers the top of the column so that water cannot get into the fill.

How many panels you need. Each panel covers 75 cm of span and 12.5 cm of height per course. A 3.00 m span between columns is closed with 4 panels per course, and a 3.75 m span with 5 panels per course. Stacking 15 courses gives a height of 1.88 m; with 19 courses you reach 2.38 m, but then the span must not exceed 3.00 m.

🧰 Installation

1. Foundation. Dig a trench 35 cm wide by 50 cm deep, place 4 reinforcing bars of 8 mm and anchor to them the vertical 8 mm bars that will run up inside each column.
2. Filling and waiting. Fill with grey M-80 mortar (minimum 380 kg/m³, that is, 1 part cement to 4 parts sand), level it off with the straightedge, water it and leave it to dry for at least 48 hours.
3. First course. Wet the pieces before placing them. Set the first column piece perfectly level and plumb, and from there keep going up with columns and panels at the same time, checking alignment with the straightedge.
4. Interlocking and reinforcing. Place the panels so that they interlock vertically with each other, fill the joint gap with mortar or cement-based adhesive and run a 6 mm vertical reinforcing bar through each joint point, anchored to the foundation.
5. Column filling. Every 6 column pieces, fill the inside with lean M-40 mortar spread evenly. On the last piece, fill right up to the top to prevent the mortar from shrinking as it dries.
6. Curing and capping. The following day, water the work for 2 days and leave it to dry for another 48 hours. Then fit the panel caps, cover the column with its cap and treat the surface with a water repellent to make cleaning easier.

📦 Available formats

• Straight panel 75 × 11 × 12.5 cm — single unit or pallet of 70 pieces.
• Curved panel 75 × 11 × 12.5 cm — single unit or pallet of 63 pieces.
• Colours: white, anthracite and sand.

💡 Professional tip: the costliest mistake is failing to plumb the first column piece properly. Each column is dry-stacked on the previous one, so a millimetre of lean at the base is multiplied by the 9 or 12 pieces that go on top: by the time you reach the top you have 2 or 3 cm of deviation, the panels no longer interlock cleanly in the notched profile and the cap no longer sits flat. Level and plumb the first piece with a spirit level in two directions and don't continue until it is perfect. And always order 5% extra panels: corners get chipped during handling, and midway through the job there is no guarantee that the replacement pallet will have the same shade. For the same reason, mix pieces from different pallets as you place them, instead of emptying an entire pallet before opening the next.

Frequently asked questions

What is the Bastida enclosure panel and what is it used for?

It is a precast concrete panel that blocks the view from outside but lets air circulate and water drain away. It is used to enclose plots, separate neighbours or conceal utility areas.

What are its dimensions and how many panels do I need per square metre?

Each panel measures 75 × 11 × 12.5 cm and the yield is 10.70 pieces per square metre. A 3.00 m span is closed with 4 panels per course and a 3.75 m span with 5.

Can the panel stand on its own or do I need more pieces?

It cannot stand on its own: it is part of a modular system. You also need the Bastida multi-angle column, the panel cap and the column cap to complete the enclosure.

What designs and colours are available?

There is a straight panel and a curved panel, which can be alternated within the same section, both finished on both faces. According to the technical specifications, the available colours are white, anthracite and sand.

What is the maximum recommended height?

The maximum recommended height is 1.88 m (15 stacked panels) with spans of up to 3.75 m between columns, or 2.38 m (19 panels) reducing the span to 3.00 m.
