Trakfloor fits the floor, not the court around it.
Four GO Corporation brands sit next to each other, and what separates them is what the buyer is actually purchasing. Indoor sports flooring is a specialist flooring trade: boards, subfloor and resilient layer built to a load class, not a coating rolled onto somebody else’s slab.

Almost every indoor floor question is one question: where does the give sit?
Put the give in the structure and the surface stays stiff, so the ball comes back and the foot does not sink. Put it at the surface as well and the floor is kinder to stand on, but it absorbs ball response and it resists a pivoting foot. That one distinction decides more specifications than any star rating does, and it decides them in both directions.
Area-elastic
Give below the surface. eight of the nine systems.
Wooden floors are identified as Area Elastic Floors - the floor has a wide area of deformation when put under pressure. It is what every ball-sport system in the range is built on, and it is rated very suitable for basketball, badminton, handball, futsal, gymnastics and dance alike.

22 mm22 millimetres. Solid hardwood 2-strip parquet, 22/20 mm
The only build in the range rated very suitable for tennis, and the only one rated unsuitable for dance. Right under a plank in a fitness studio, wrong under a pivoting dancer. The manufacturer marks both, on the same page.

Two things decide whether a hardwood floor survives here.
Neither of them is the sport. The coating is answered before the floor leaves the factory. The moisture is answered half there and half here: KTL condition the boards for this climate, and the slab underneath is ours to measure and specify against. Both hold for the seven systems KTL surface themselves, which is all of the range except the two where they supply the subfloor and the covering is a third party’s.
The boards are conditioned for the climate they are going into.
An imported hardwood floor arrives seasoned for somewhere else. That is one of the two ways it gets ruined here. The other is the slab it is laid on.
Timber moves with the moisture around it. Boards conditioned for a European winter take up humidity here and push against each other until the floor cups, lifts or splits at the perimeter. It happens months after handover, long after anyone is watching.
This is a board-side answer. It says nothing about the slab, which in this climate is the other half of the problem and is ours: we measure slab relative humidity with in-situ probes left to equilibrate, to BS 8203 and ASTM F2170, and the reading decides whether a membrane goes in and which one. Not the habit of always fitting one, and not the habit of never.
The coating is cured in a factory, not rolled on in a sports hall.
It is the difference between a floor a cleaner can put a machine over and a floor that has to be closed, sanded back and recoated.
A site-applied lacquer cures in whatever air the hall happens to have that week. KTL apply a seven-layer UV-cured coating under factory conditions instead. Game lines then go on over that cured coating, and no clear top coat is applied after them; on the portable design floors the lines are printed into the panel before the final lacquer coats instead.
On durability the number to hold on to is the abrasion strength: KTL put the factory coating at around three times that of a lacquer applied on site, with a ten-year warranty on it at normal wear. Abrasion resistance is precisely what decides how fast a coating is worn through to the point where the floor has to be closed, sanded back and recoated, so a longer interval between refinishes follows from it. How much longer depends on how hard the hall is worked, and no recoat interval is published to multiply, so we do not put a figure on it.
One claim here is ktl, direct to us on 2026-09-04. not in the published catalogue.
Six spaces, and the thing about each one that is not obvious.
A space is a room, not a project. Each one starts from what the room is for, scores the range against the sports it actually serves, and ends with the system we would specify and the ones we would not. The reasoning is the product.
Ballet room
A dance studio with a mirror wall, a barre and an existing threshold.
A ballet floor wants sprung, not soft.
Rated very suitable for dance, and at 32 mm it is the lowest solid-hardwood build in the range. In a retrofit with an existing threshold and a mirror wall, build height settles the choice before performance is discussed.
Multi Clip SystemEN 14904 A332 mm
Basketball court
A competition court, with seating and equipment that has to be moved.
Load class beats the star rating.
High point and rolling load, EN 14904 class A4, and a FIBA licence of its own. KTL name retractable seating explicitly in what it was designed to carry.
FlexiPRO 12 V3EN 14904 A439 mmFIBA WF73-06
Multi-purpose hall
A school or community hall: sport in the morning, assembly in the afternoon, a concert on Saturday.
The manufacturer’s own recommendation contradicts the manufacturer’s own ratings.
Ties at the top of the hall score, carries EN 14904 class A4 with both a FIBA licence and BWF Grade 1, and its standard load class is exactly what KTL define a hall to need.
A dedicated badminton hall, or a hall where badminton is the sport that matters.
Moving up the range moves you off the certification.
BWF Grade 1 and rated very suitable for badminton. Its one weakness, standard load, is irrelevant to a sport with no seating trolleys and no staging trucks.
A studio for mat work, class fitness and light equipment. Not a weights room.
Aerobic and fitness are the only two sports of eighteen that KTL never rate very suitable.
For yoga and mat work: rated very suitable, 32 mm, and the lightest load case in the range is the one this room actually presents.
Multi Clip SystemEN 14904 A332 mm
Portable event floor
Not a room. A mode of use: a floor that is laid, played on, and taken up again.
A portable floor leaves out more work than it adds.
BWF Grade 1, rated very suitable for badminton, and high point and rolling load in a floor that is meant to be lifted.
Portable PROEN 14904 A444 mmBWF Grade 1 International Elite
Nine systems. The star ratings barely separate them.
six of the nine are rated very suitable for basketball and eight of the nine for badminton, so the sport rating is rarely what chooses. Load class, build height and which federation licence a system actually holds are what choose.

Load reads High or Standard for both point and rolling load. Standard is not a lesser floor, it is a different load case, and in a school hall it is the correct one. In an arena carrying telescopic seating it is not.
Certification is per system, and it is the gate.
FIBA approval carries a licence number against a named system, so a floor either has one or it does not, and a manufacturer’s membership is not a substitute. Where a certificate exists we quote the number. Where it does not, we say so rather than implying one.
Badminton is the case in point. BWF Grade 1 International Elite appears on three systems and is stated as those words, with no certificate reference anywhere in forty pages. We ask for it. We do not print one that has not been issued.

What the catalogue does not contain.
The manufacturer published a marketing catalogue, not a datasheet. Every page of it was read and the absences below were recorded rather than assumed away, because on a floor specification the missing number is usually the one that decides something. None of these gaps stops a floor being specified. All of them go on the enquiry.
Any price, rate, budget figure, MOQ, incoterm or lead time.
Panel dimensions and weights for the portable systems - 'light weight panels' is the only statement.
Board widths other than the 22x130 mm quoted on the fixed-system detail pages.
Per-species technical properties.
Shock absorption / vertical deformation / ball-rebound VALUES - only the EN 14904 class letters.
Warranty terms beyond '10 years on the 7-layer UV coating at normal wear and tear' (p8).
Maintenance and cleaning regime - listed as a choosing factor on p3 but never covered.KTL have since answered part of this directly. What they said, and what it still does not cover, is on the systems page. Read it there.
Any statement about slab moisture, DPM or Thai tropical-humidity slab conditions; KTL's moisture story is entirely board-side (customised moisture content, back-lacquered boards).
That includes price. There is no rate, no budget figure and no lead time anywhere in the document, so there is none on this site either. Any number here would be ours rather than the manufacturer’s, and a floor is not something to guess at.
Send us the room, the sports and the heaviest thing that will ever cross the floor.
Those three answers narrow nine systems to one or two, usually in the first reply. What we cannot do from here is quote you: that needs a manufacturer’s quotation, and we will tell you when we have one.
