Concrete walls in Sintra

Yes, we deliver and install in Sintra. Our warehouse is in the Greater Lisbon area, a 42.3 km from the municipality seat — about 31 minutes of road. The most common plot here is granite rock with boulders, which makes the installation demanding. It is the plot, more than the length of the wall, that governs the lead time.

Delivery from our warehouse

We have our own warehouse in Greater Lisbon. From the warehouse door to Sintra town hall it is 42.3 km, about 31 minutes of road. The four stock textures leave without waiting for production; what is made to order goes into manufacturing first.

Delivery is made entirely on the north bank, without crossing the Tejo: fewer variables in scheduling and no bridge toll cost.

Distance and time measured by actual road routing to the municipality's main town, not as the crow flies. Within the municipality the figure varies with the parish.

Salty air

This municipality has an exposed waterfront. It is where the difference between concrete and metal stops being aesthetic: concrete does not corrode or react to salt air, unlike any galvanised metal fence. The panel's water absorption is ≤ 6 %.

This applies to the wall, not to the accessories: gates, hinges and locks are still metal and still need maintenance near the sea.

What ground you will find in Sintra

In a precast concrete wall, almost all of the site time goes into drilling the post holes. That is why it is the plot, and not the length, that governs the lead time.

Demanding Granite rock with boulders. Hard rock and, in the soil above it, loose blocks of stone that turn up without warning.

What that means in practice

The most demanding ground in the region. Besides rock, unexpected blocks appear at mid-depth that force the post to be moved or the tool to be changed halfway through the hole.

Slow and less predictable pace. Here a quote without seeing the site is a guess.

In this particular municipality

The igneous massif makes this the most demanding ground in the Lisbon Metropolitan Area for drilling holes, with loose blocks appearing at mid-depth. On the other hand, it is one of the municipalities with the most detached houses with land — and therefore more metres of wall per site.

A geological term, for anyone who wants to check: Maciço eruptivo de Sintra. The Sintra alkaline intrusive massif — granites and syenites — with a hardened contact aureole and loose blocks in the covering soil.

This is the municipality standard, not a guarantee for your plot. Two plots on the same street can have different layers, and old backfill turns up where nobody expects it. The lead time is only firm once we have seen the line of the wall — until then, what is here is meant to give you an idea, not to plan the works.
Each post is concreted into a hole of 300 × 300 × 800 mm, with 800 mm buried — the minimum is 700 mm. It is that embedment that ensures the wind resistance of the segment, and it is what the local geology makes easy or difficult.

Level or stepped?

SlopedPlot with a marked slope. Here the wall is almost always built in steps: each 2 m segment sits at its own level and the top of the wall steps down instead of following a straight line.

What this changes in the wall

Expect stepping along a good part of the line. The wall is higher on the upper side of each step, and that changes the panel count.

An example to give a sense of scale: on a 5 % slope, a 50 metre wall drops 2.5 metres from one end to the other — five courses of 500 mm panel. That is why on a sloping plot the number of panels is not calculated from the length alone.

How we measure

Local slope median of 14.2 % in this municipality. Measured at 14 points spread across the territory, comparing the altitude of each point with four neighbours 120 metres away — roughly the length of a real wall. The median is used so that an isolated slope does not classify a flat municipality as sloping.

As with the terrain, this is the municipality average and not your plot. A flat plot in a sloping municipality is perfectly possible — and the other way round too.

Licensing in Sintra

The requirements are municipal: they depend on the height of the wall, its position relative to the public road, the property boundary and what the PDM for Sintra lays down. We are not going to tell you it "is not needed" just to close a sale. Check with the municipal council before going ahead; if needed, we provide the dimensions and the drawing of the wall to support the application.
