FACTS TO CONSIDER WHENSPECIFYING

Compliant with EN 14904 (surfacesfor sports areas – indoor surfaces formulti-sports use – specification)The patented rubber crumb cradlesare manufactured from recycled tyresreducing their impact on theenvironment.Timber battens pre-supplied fromFSC/PEFC certified forests.No screed is required so there is nodrying time and job completion isquicker.Floors can be laser-levelled on site toprovide a completely even floor.U values (thermal) can be achievedwhich reduce the need for underfloorheating and allow the floorinsulation to provide additional usercomfort.Services can be installed under thefloor if required.Full technical back-up and on-sitetraining is available.Sports floors must be able to safelywithstand the loadings of users andequipment as defined in BS 6399.

Specification standards for multi-use sports floors

The requirements of EN 14904 and BS 7044: Part 4, for indoor surfacesfor multi-sports use, apply to the complete surface i.e. both the finishedlayer and the sub-floor.

Tarkett Sports Systems comply with, and exceed, both standards. Theyare impact energy absorbing and suitable for a wide range of sports (e.g.basketball, football, handball, hockey, netball, tennis) as well as non-sporting activities (e.g. use as an exam hall or for community activities).

They have been comprehensively tested against British and EuropeanStandards and copies of the appropriate certification are available onrequest.

The owner or operator of a sports facility is responsible for ensuring thatthe sports floor is suitable for use from a safety aspect, while thepurchaser of the floor (if different from the owner/operator) shouldrequest the appropriate test certification by the floor manufacturer. Thisinformation is readily available from Tarkett Sports.

Shock Absorbing

The test result for shock absorption shows how much of the impactenergy resulting from a landing is returned to the athlete’s legs andback. The ability of the floor to absorb this shock depends on itselasticity and should be sufficient for the athlete to avoid unwantedstrains.

With Tarkett Sports System floors, the combination of the timber battenssupported in rubber crumb cradles, with plywood overlay and Tarkettsports surface layer, or 22mm sports board provides excellent shockabsorption properties for multi-use games and play areas.

Installation instructions

The following instructions are issuedas an aid to the correct installationprocedures. Individual site conditionsmay necessitate variances to thesestandard instructions. Such casesshould be referred to the TarkettTechnical Department for approval.All installation and working practicesshould be in accordance with relevantCodes of Practice, current BritishStandards and HSE Regulationsapplicable to the constructionindustry.

SITE PREPARATION

If a screed has been applied itmust be fully cured beforebeginning the installation of thecradle and batten systemBuilding to be dry andweatherproofEnsure that all materials areunpacked and left in the area to belaid for a minimum 24 hours priorto installation. This is to allow foracclimatisation to temperature andhumidity levels which should beset and maintained to matchfuture ‘in-use’ conditionsInstacoustic adhesive and sealantshould not be subjected totemperatures of less than 5°c.Floor receiving the cradle andbatten system must be

• Hard• Dry• Free of all debris• Reasonably smooth – tampedfinishes are acceptable

All beam and block or concrete befully grouted

TOOLING REQUIRED• Laser leveller• Circular saw• Jigsaw• Hand saw• Pencil• Utility knife• String line• Battery drill• Countersink bit• Tape measure

STEP 1 DAMP PROOF MEMBRANE (OPTIONAL)A damp proof membrane is recommended on ground floor slabsand new concrete bases above ground level. (See points to note).

STEP 2 BATTEN CENTRESStart, usually at the point furthest from the doorway (wall A), bymeasuring out the batten centres (Fig.1). For example, for theSP18/43 (400 x 600) system, mark out every 400mm to give thecorrect batten centres. Mark out the batten centres on theopposite wall (wall C) and, using a chalk string line, ping or markbetween the matching marked points (Fig.2).

STEP 3 CRADLE CENTRESMeasure out the cradle centres along the batten centres by walls Band D. The cradle centres vary according to which batten is beingused. For example, for the SP18 system with a 43mm deep battenthe cradles will be at 600mm centres. Using this example, measure600mm along both B and D perimeter chalk lines, starting fromthe same end (e.g. wall A) and mark or ping a chalk line betweenthe corresponding points to create a grid (Fig.3).

STEP 4 CRADLE POSITIONINGPlace the cradles around the perimeter on all the marked points,ensuring a 30mm gap between the wall and the cradle edge, andat each chalk line intersection (Fig.4).

STEP 5 FLOOR HEIGHT VARIATIONSUsing a laser levelling system, establish the highestdatum point of the floor. Calculate the differencebetween the datum point and every cradle andwrite the figure, on the floor, next to each cradle(Fig.5).

STEP 6 HEIGHT ADJUSTMENTInsert the appropriate quantity and combination of 2mm and 5mmcradle packers into each cradle equal to the noted heightdifference, e.g. 6mm = 3 x 2mm packers; 14mm = 2 x 5mm + 2 x2mm packers. The cradle packers should be placed in line with thedirection of the battens. When packing under the join of two orthree battens make sure the packer is supporting all battens.Packers can be used to a maximum of 5mm below the top of thecradle leg. Additional height can be achieved by using 10mm and30mm cradle base packers.

STEP 7 BATTEN PLACEMENTInsert the timber battens into the cradles. Start around theperimeter and then along the original marked ping lines. Timberbattens should be laid in a staggered formation and all battensmust join within a cradle. (Fig.6).

STEP 8 THERMAL INSULATION (OPTIONAL)If required, the thermal insulation should be laid between thetimber battens. InstaCoustic can provide ‘U’ values for theinsulation.

STEP 9 EXPANSION STRIPPlace the expansion strip around the perimeter of the roombetween the wall and the cradles. (Fig. 7).

POINTS TO NOTEMEMBRANE (IF REQUIRED). A membrane,such as 1200 gauge polythene sheeting,should be installed over all ground floorslabs and new concrete bases above groundlevel. Joints shall be lapped a minimum of150mm and should be taped and sealedwith waterproof adhesive tape, with edgesupturned to the same height as the tongue& grooved overlay boards at all perimeterwalls.

SERVICES If there is insufficient room torun services beneath the battens, servicesmay be accommodated by cutting thebattens and passing the service throughthe batten. Support the cut batten, leaving10mm-15mm clearance from the service,with additional cradles supporting the cutbattens.

Never notch the battens. Services runningat the perimeter of the room must be aminimum of 150mm from the perimeterand should not be grouped any wider thanthe available space between the battens.

INTERMEDIATE BOARD SUPPORT When theshort ends of the boards do not join on abatten, they should be supported withintermediate cradles and battens (see fig.A). Where boards join without beingtongued and grooved, such as in doorways,support the join with intermediate cradlesand battens. Screw and glue the boards tothe batten with a 2mm gap between theedges of the boards to avoid squeaking.Batten spacing may be adjusted to suitroom sizes to minimise waste provided themaximum batten spacing is not exceeded.

ABNORMAL LOADING If the cradle andbatten system is to be subjected toabnormal loading, it may require the use ofadditional cradles. In such cases pleaserefer to the InstaCoutic TechnicalDepartment for advice.

SPORTS EQUIPMENT SOCKETS/ACCESSHATCHES Due to the type of sub-floor, theuse of free-standing equipment isrecommended. When it is inevitable thatsockets are required, these should be fixedinto the concrete base with an extendedsleeve to allow for height, once thebattens have been levelled and prior to thefixing of the boards. This will allow thefinished level of the socket lid to beaccurately calculated. The equipmentmanufacturer/installer should also beconsulted, since accurate location iscritical. Access hatches can normally beaccommodated. It is essential that whenboards are cut they are adequatelysupported with additional sports cradlesand timber battens.

FLOOR COVERINGS A careful check shouldbe made prior to installation of Tarkettflexible sports surfaces, to establish ifthere are any raised joints which should besanded to eliminate the possibility of thejoint “grinning” through the playingsurface. The use of cementitious levelingcompounds for timber floors is notrecommended. Tarkett Sports should beconsulted at an early stage in the project.

ADHESIVES The installing contractor isresponsible for ensuring adhesioncompatibility between the overlay boardsand the specified sports surface. TarkettSports can provide advice on compatableadhesives.

STEP 10 PLYWOOD• Apply adhesive to the top of the cradle battens and lay the

boards at 90° to the battens.

• A 30mm gap around the perimeter must be maintained andthe expansion strip must not be squashed.

• As the boards are laid the adhesive should be applied tothe tongue and groove edges of the boards.

• Boards should be laid in a staggered formation ensuringjoins are a minimum of 150mm apart

• Edges on the short side of the boards must join on abatten

• The boards are screwed down using countersunk woodscrews as in the screw fixing pattern, Fig. D below.Perimeter fixings on the long edge of the boards shouldnot exceed 600mm. Fixing centres along the cradle battensshould be at 300mm and 150mm from the long edgeperimeter. Where boards join on the short edges theyshould be screwed down in two places both sides of thejoin.

STEP 11 MAKING GOODOnce the plywood boards have been laid and the TarkettSports Surface has been applied, cut away any surplusexpansion strip with a sharp builder’s knife. If required,skirting can now be fitted (Fig. 8). FIG 8
