1. Why Does Sand Infill Deserve Its Own Guide?

Ask most buyers what makes a padel court good and you will hear about the steel, the glass, the turf density and the certificate. Sand barely gets a mention — and that is a mistake. Sand infill is not a filler you get "for free" with the turf; it is a functional component with its own specification, its own installation procedure and its own maintenance routine. Get it right and the court plays the way it should from day one. Get it wrong and you will spend years fighting a surface that grips too much, slides too little, or bounces the ball inconsistently.

There are three reasons sand deserves its own guide rather than a page tucked inside a general construction article. First, it changes the ball behaviour. The silica sand locks the fibres in an upright position, giving the ball a stable, predictable bounce and letting players execute the low, sliding shots padel is known for. Second, it is a moving, wearing component. Sand is not static — it migrates toward the edges, is lost through the drainage layer and carried out on players' shoes, so the court slowly changes character as the sand level drops. Third, it is the cheapest high-impact upgrade. A mistake in sand quantity or type is inexpensive to correct compared to replacing the whole turf layer, which makes sand one of the rare things a club can materially improve with labour rather than capital.

For a B2B buyer — an importer, a developer or a club owner staying on top of a facility — sand infill matters because it is the single easiest way to make a court play consistently and last longer, and it is also the most common way to under-serve a court after the turf is down. This guide covers the complete picture: how much sand, what grade, how to install it, and how to keep it right for the life of the court.

2. How Do the Turf and Sand System Work Together?

A sand-filled padel turf is really a two-part system. The turf carpet is the visible layer — the monofilament fibres — and the sand infill is the mass that sits between them. Neither works well without the other, and the combination defines how the surface plays.

Most competition padel turf is a 24 mm monofilament carpet at roughly 10,000–13,000 stitches per m². The fibre itself provides the texture and durability; the sand provides the weight that holds the fibres upright, the shock absorption and the grip. When sand is at the correct depth, the fibre tips protrude just above the sand and the surface gives a controlled slide. When the sand is too shallow, the fibres lie flat, the court feels too fast and slippery, and the ball skids rather than checks. When it is too deep, the surface becomes slow and heavy, the ball bites too much and players risk knee and ankle fatigue.

Component	Typical spec	What it controls
Turf pile height	24 mm monofilament	Fibre durability and upright recovery
Turf stitch density	10,000–13,000 stitches/m²	Durability and resistance to flattening
Sand infill	14–20 kg/m²	Ball bounce, grip and the controlled slide
Fill depth	60–70% of pile height	Balance between slide and traction
Sand grade	0.2–0.8 mm rounded silica	Durability of the fibres and easy packing

The practical point: turf and sand are ordered as a matched set. Ask your supplier for the recommended sand quantity and grade that goes with the specific turf you are buying, rather than assuming any sand works. A manufacturer that supplies both will tell you the fill rate for their own turf — which is the figure you should trust.

3. How Much Sand Does a Padel Court Really Need?

This is the first number a buyer wants, and it is straightforward once you know the playing area. A standard doubles court has a 200 m² playing surface (20 × 10 m). At the industry fill rate of 14–20 kg/m², that works out to roughly 3–4 tonnes of sand per court, depending on the turf density and the target depth.

• Minimum fill: about 14 kg/m², useful on a lower-pile or lighter turf.
• Standard fill: around 16–18 kg/m², the typical target for a club-level court.
• Deep fill (heavier play): near 20 kg/m², used where a slower, more forgiving surface is preferred.

Because a 3–4 tonne load is significant, it also affects logistics and, on some builds, the foundation. A full 40–60 kg/m² of combined turf and sand sits on the slab, and this is a figure your structural engineer needs to check — particularly for rooftop courts where the additional weight matters. Before you buy, confirm exactly how much sand your chosen turf requires and whether that weight is accounted for in the structure.

For the turf itself, a 200 m² court needs about 230 m² of turf — the extra covers seam overlaps and the cuts around posts and doors. Order the turf and the sand as a matched quantity from a single source so there is no guessing on the fill rate.

4. Which Sand Type Should You Use?

Not all sand is suitable for a padel court. The wrong sand wears the fibres, packs into concrete or holds moisture — and the fix is painful. The specification that works is very specific.

• Silica sand, not beach or masonry sand. Rounded, washed silica sand is the standard. Field or beach sand contains silt and clay, which bind and can harden the surface over time.
• Rounded, not sharp or crushed. A rounded grain slides over the fibres without cutting them. Sharp, angular sand acts like abrasive and shortens turf life.
• Oven-dried. Dry sand flows easily and spreads evenly. Damp sand clumps and will not distribute to a consistent depth.
• Sized 0.2–0.8 mm. This is the common padel grading. Too fine and it packs and dusts, too coarse and it looks and feels wrong under foot and shifts too easily.
• Clean, low dust. A washed, low-dust product is easier to handle and keeps the court and the club premises cleaner.

A simple rule: do not substitute. The sand grade is matched to the fibre width of the turf you choose. If a supplier suggests a shortcut grade, ask why, because the answer usually means a cheaper, less durable surface.

Red infill for padel courts: quantity, colour and cost

Dutch-language enquiries usually write this line as rode infill voor padel — literally “red infill for padel” — and the question behind it is always the same: does the red product behave differently from the natural sand? These are the figures we quote against.

Item	Figure	Why it matters
Quantity for a 20 × 10 m court	14–20 kg/m² — roughly 3–4 tonnes per court	The fill rate does not change with colour; the turf density and the target depth do
Grain and grade	0.2–0.8 mm rounded, oven-dried silica — pigmented or natural	Pigmented product uses the same rounded grain, so it slides over the fibres the same way
Fill depth	60–70% of pile height; outdoor courts sit at the heavier end (18–20 kg/m²)	Depth and pile height control ball speed — colour does not
Unit price (indicative)	USD 0.30–0.50 per kg; USD 1,200–2,000 of infill per court	Buying the sand locally is often cheaper than shipping it inside the kit
Colour families allowed by FIP	Green, blue or terracotta and their like tones — one colour across the whole floor and clearly different from the walls	The floor colour is regulated; the palette sits outside the playing standards for bounce, planarity and grip
Batch consistency	Shade is fixed per production batch	Agree the red shade in writing against the turf colour before production — a colour change afterwards is a new order, not a swap
Annual top-up	5–10% of the sand is lost every year on a busy court	Top up with the same colour batch, or the repaired zone shows against the rest of the court

Quantity and depth do not change with the colour. A 20 × 10 m court takes 14–20 kg/m² — roughly 3–4 tonnes of sand — filled to 60–70% of pile height, with outdoor courts at the heavier end (18–20 kg/m²). Red infill follows exactly the same rule, because the colour sits on the same 0.2–0.8 mm rounded, oven-dried silica grain.

Cost is quoted per court, not per colour. At USD 0.30–0.50 per kg the infill line on one court lands at USD 1,200–2,000, identical for natural or pigmented sand. What does differ is the batch: the shade is fixed per production run, so the red approved on the sample is the red delivered, and any later top-up has to come from that same batch.

The practical conclusion: specify the colour on the same line as the quantity. "Red infill" on its own is not a specification — the numbers that decide how the court plays are the kg/m² and the pile height, and the colour is quoted on top of them. The table above is the buying list to quote against; how the turf, pile height and drainage sit around it is covered in the padel court flooring guide.

5. How Do You Install Sand Infill on a New Court?

Sand infill on a new court is a batch job done in stages, not one dump-and-forget pass. The goal is an even depth at the target percentage of pile height across the whole surface. Here is the practical sequence.

1. Deliver the sand on-site and keep it dry. Store it under cover. Wet sand is far harder to spread evenly and clumps as it dries.
2. Spread the sand in a first pass. Use a mechanical infill spreader for large courts, or a cardboard-sled and hand rakes for a small single court, distributing the sand roughly across the surface.
3. Brush it into the pile. Drag a stiff-bristled brush or a powered groomer across the court to work the sand down between the fibres. The brush lifts the turf and settles the sand to depth.
4. Level and even out. Drag a weighted drag mat or drag brush across the surface to fill the low spots and bring the depth to a uniform level.
5. Consolidate and water. On many systems, a light watering helps the sand settle into the base, then allow it to dry. Some turf specifications prefer a dry-consolidation method — check the manufacturer's recommendation for the actual turf you are installing.
6. Repeat until depth is right. A full fill is usually achieved in two to three passes, checking depth at intervals with a depth gauge where the manufacturer provides one, and topping up low areas between passes.

Two points matter most. First, do not dump all the sand at once — spread, brush and level in passes so the depth stays even. Second, verify the fill depth against the manufacturer's target before you call the installation finished. A court with a visibly wrong sand depth is a court that will need re-work or months of playing to settle.

6. How Do Sand Depth and Ball Speed Affect the Fill?

The most common fault in a new or maintained court is the wrong sand depth, and it shows up in the play. Sand depth directly changes the ball's interaction with the surface.

• Too shallow: fibres lie flat, the court plays fast and slippery, the ball skids, and the surface wears quickly because the fibres are not cushioned.
• Too deep: the court plays slow and heavy, the ball bites and checks too much, and players use more energy — a fatigue and injury risk.
• Just right (60–70% of pile height): the fibre tips stand just above the sand, giving the balanced grip and the controlled slide that the sport is built on.

The takeaway for a buyer is that sand depth is a spec you can measure, not a feeling. Spend a little time at handover confirming the depth rather than trusting that it "looks fine." And keep the target number from the manufacturer in the maintenance plan so it is never lost.

7. How Often Should You Top Up and Replenish the Sand?

Sand is a wearing component, so the real question is not "do I add sand?" but "how often, and how do I know when?" The answer is governed by use, and it is one of the most-asked maintenance questions for a padel court — especially on outdoor courts.

A well-used court loses about 5–10% of its sand every year. Sand migrates toward the edges, is washed out through the drainage layer and carried away on players' shoes. Over a few seasons that is a meaningful change in how the court plays. The practical routine:

• Check the sand depth quarterly — at least four times a year, and monthly on a heavily used club court.
• Top up as needed rather than on a fixed schedule. Brush the surface evenly, and add sand where the depth has dropped, usually a light top-up rather than a full refill.
• Full re-fill or re-sand after major turf work, or when the depth is consistently low and a top-up no longer restores the play.
• Seasonal attention for outdoor courts. In wet climates, sand is lost faster; in hot, dry climates the surface dries out and the sand can become dusty. Adjust the routine to your climate.

The signals that tell you the sand is getting low are easy to read: the court looks flatter and shinier, the fibres no longer spring back cleanly, the ball skids off more than it used to, and players comment that the court "has gone fast." If you see any of these, check the depth before you assume the turf has worn out — a sand top-up is far cheaper than a new turf.

8. What Brushing, Grooming and Infill Equipment Do You Need?

None of this needs to be expensive, but the right equipment makes the difference between a flat, even surface and one you are constantly fighting. For a single court, a hand drag-brush and a stiff rake can do the weekly job. For a club with several courts, powered equipment saves hours.

• Drag brush / drag mat: pulls the sand level and works it back between the fibres after play.
• Infill spreader or hopper: distributes new sand evenly when topping up.
• Powered groomer / turf brush: the efficient option for multi-court facilities, lifting the pile and redistributing the sand.
• Depth gauge: a small tool for verifying the sand depth against the manufacturer's target.

The routine is simple: brush regularly and check the depth. Weekly brushing after heavy use, quarterly depth checks, and a light top-up whenever the depth falls, will keep a good court playing well for many years. For the full court-care picture, see our padel court maintenance guide.

9. What Common Sand Infill Mistakes Should You Avoid?

Sand infill is where a lot of courts go wrong, and the mistakes are predictable.

1. Using the wrong sand. Crushed, sharp or silty sand wears the fibres and packs hard. Use clean, rounded, oven-dried silica at 0.2–0.8 mm.
2. Filling the wrong amount. Under-filling makes the court fast and slippery; over-filling makes it slow and heavy. Match the fill to the manufacturer's rate.
3. Dumping it all at once. Spreading in passes gives an even depth; dumping gives an uneven surface that needs re-work.
4. Ignoring the top-up. Sand is a wearing component. Neglecting the quarterly check and the occasional top-up is the fastest way to shorten turf life.
5. Forgetting drainage. Sand needs to drain. A court with poor drainage turns the sand into a muddy problem instead of a playing surface — see our drainage guide.
6. Buying turf and sand separately. Different suppliers mean mismatched specs. Buy them as a matched set so the fill rate and grade are guaranteed.
