Pool Enclosure Base: How to Prepare the Ground for Your Enclosure

Everyone loves choosing the fun bits of a new enclosure: the height, the colours, the panels. The ground underneath gets far less attention. Yet a good pool enclosure base is what lets your enclosure glide open smoothly on a sunny morning and sit snugly closed when the next downpour rolls in.

The good news is that the ground rules (sorry) are fairly simple. In this guide, we'll go through what your surround needs, whether an enclosure can sit on decking, how recessing the track works, and what to sort out before the survey and delivery.

Why Does the Pool Enclosure Base Matter So Much?

Our made-to-measure enclosures run on tracks. Each segment glides over the next as you open or close the pool, and that smooth, easy movement relies on the tracks sitting on a surface that's flat and solid.

If the ground dips, rocks or sinks, the tracks can't do their job properly. Segments may not line up neatly, sliding can feel stiff, and the enclosure won't sit as snugly as it should.

Because every enclosure is made to order and built to your pool's exact measurements after a site survey, it pays to get the surround right. A beautifully made enclosure deserves a base to match.

What Does the Ground Need to Be?

There are two simple requirements.

Is It Flat?

The area where the tracks will run needs to be flat. Not "flat-ish", and not "flat apart from that one slab the tree root lifted". Flat.

That matters most along the full length of the tracks, including the extra space at the end where the segments stack up when the enclosure is open. Our guide to choosing your pool enclosure size and height explains how to allow for that parking space.

Can It Take the Weight?

The ground also needs to be able to take the weight of the enclosure. Every enclosure is different, depending on its size, height and design, so we won't quote a single figure here.

Instead, this is one of the things our team looks at during the site survey. If you have any doubts about your surround, such as older paving, a patch you know has moved, or a raised area, mention it when you first get in touch.

Can a Pool Enclosure Be Installed on Decking?

Yes, it can. Plenty of pools are surrounded by decking, and that doesn't rule out an enclosure.

The same two rules apply: the decking must be flat, and it must be able to take the weight. Decking that's sound, level and well supported is a good starting point. Decking with soft, springy or rotten boards needs sorting out first.

Let us know at the enquiry stage that your pool has a decked surround, so it can be assessed properly at the survey.

Should the Track Sit on Top or Be Recessed?

You have a choice here, and it's worth deciding early.

Leaving the Track on the Surface

Our enclosures use a slim 14mm track, which can simply sit on top of your paving or decking. For many gardens, that's the easiest option, with no groundwork needed beyond making sure the surface is flat and solid.

Recessing the 14mm Track

If you'd rather have the track flush with the surround, the 14mm track can be recessed into the ground. That means cutting a channel into the paving for the track to sit in.

There's one important catch: the channel must be prepared before delivery. It needs to be cut and ready by the time your enclosure arrives.

When you cut the channel, allow 3cm of leeway either side of the track (6cm in total). In other words, don't cut it tight to the track.

We'll confirm the exact channel details for your enclosure before any cutting starts, so please check with us before anyone gets the saw out.

Laying New Paving?

If you're re-paving around the pool anyway, there's a simpler route. The paving can go in after the enclosure is installed, so there's no need to cut a channel in advance. The new paving is laid up to the track instead.

If that's your plan, tell us early so we can arrange the installation around your paving work.

What If the Enclosure Won't Sit on the Ground at All?

Not every enclosure has to run on tracks at ground level on both sides. If your pool sits right beside the house or a garden wall, there are wall-mounted options too.

These include lean-to designs, and designs where the enclosure's track sits on top of a wall or a frame, such as a pergola or similar structure. In that case, the wall or frame effectively becomes part of your pool enclosure base, so it needs to be sound, level and able to take the weight, just like paving.

If you think a wall-mounted design might suit your garden, mention it early. It's something our team would look at closely during the survey.

Why Is It Worth Getting the Ground Right First?

It's tempting to see groundwork as the boring bit. But a flat, solid surround is what lets a made-to-measure enclosure do what it does best: glide open easily, close neatly and keep doing so for years.

Sorting the surround before your survey also keeps things simple. The measurements taken are the ones your enclosure is built to, the installation day runs smoothly, and you're not left fixing paving around a brand-new enclosure.

How Do You Check Your Existing Pool Surround?

You don't need to be a builder to do a quick check. Before your survey, walk around the pool and look for:

• Uneven areas: lay a long straight edge (a length of timber works) along where the tracks will run and check it with a spirit level
• Loose or rocking slabs: step on each one along the track line
• Cracks, dips or sunken patches, especially near drains or old tree roots
• Changes in level, such as steps, raised edges or slopes along the track line
• Obstacles such as pool lights, pumps, taps, planters or furniture near the edge

Also think about where rainwater goes. After a proper British downpour, notice whether water collects anywhere along the track line. If you're planning to recess the track, mention it at the survey so drainage can be part of the conversation.

What Should You Sort Out Before the Survey?

A little preparation makes the survey more useful and keeps your quote accurate:

• Fix loose or damaged paving along the track line, or plan to
• Decide whether you'd like the track recessed or on the surface
• Tell us if you're planning new paving, and roughly when
• Clear the area around the pool so the surround can be seen and measured
• Think about access: during the survey, our team checks how the enclosure can get to your garden, including whether a crane is needed

If you've got photos of your pool and surround, send them over when you first get in touch. They help us give you an initial estimate.

What Happens at the Site Survey?

Our team visits to take precise measurements and assess the installation area. That includes the surround, access to the garden and anything that could affect the fit.

Once everything's confirmed, you get your final quote. If there are no surprises at the survey, the price stays the same as your initial estimate.

Your enclosure is then made to order. Lead times on our product pages are typically 8 to 12 weeks, depending on the model, which gives you time to finish any groundwork or channel cutting before delivery day.

Frequently Asked Questions

Does my pool surround need to be perfectly flat?

It needs to be flat along the track line and strong enough to take the weight of the enclosure. If you're unsure, we'll assess it during the site survey.

Can a pool enclosure go on decking?

Yes, as long as the decking is flat, in good condition and able to take the weight.

Do I have to recess the track?

No. The 14mm track can sit on the surface. Recessing it is optional, but if you choose to, the channel must be cut before delivery with 3cm of leeway either side (6cm in total).

What if I'm replacing my paving?

The paving can go in after the enclosure is installed, so you won't need to cut a channel in advance. Just let us know your plans early.
