1. WOOD, A NATURAL MATERIAL
Beinganaturalmaterial,woodwillhavesomeimperfections.Thesearenormalandhavenoimpacton
theservicelifeoftheproduct.Acertainnumberaresupercialanddonotfallwithinthescopeofthe
guarantees.
1.1 Resin beads
Whenresinouswoodspeciesareautoclaved,thealternatingpressure
andvacuumcancausestickyresiduetorisetothesurface.Toremove
it,scrapeitcarefullywithanappropriatetool,beingcarefulnottotouch
thewood.Turpentinespiritscouldalsobeeffective,butcouldstainthe
woodiftoomuchisapplied.
1.2 Salt stains
Les bois traités en autoclave montrent fréquemment de petites taches
vertes en surface. Si vous le souhaitez, vous pouvez les poncer
légèrement. Cette couleur disparaîtra dans le temps.
1.3 Greying
Wood exposed to the elements is susceptible to greying. Some people
appreciate the silvery sheen of this natural patina.e.
1.4 Splitting and cracking
Woodexpandsandcontractswhenexposedtovariationsinhumidity
andtemperature.Asitdries,woodcontractsunevenlyresultinginthe
appearance of cracks. While these can seem to be cause for concern,
they have no impact on the mechanical properties of the product and
thereforedonotfallwithinthescopeoftheguarantee.
1.5 Knots
Knots mark the places where branches were attached. The quantity
andsizedependsonthespeciesofwoodandthesortingprocess.For
outdoorinstallations,smalladherentknotsareacceptable.Themore
woodissortedtolimitthesizeandnumberofknots,themoreexpensive
thewood.
1.6 Joined wood
Toensurethehighestqualityintheselectionofourwood,itissorted
meticulously before planing. Sections that feature defects (knots,
cracks,etc.)onbothsidesareremovedandthewoodisthenjoined
together(seeimage).Itisnotunusualtondjoinedslatsinthewooden
poolstructure as thisinnoway penalises themechanicalproperties
ofthewood.Similarly,imperfectionsontheinnersurfaceofthepool
structure (knots, cracks, etc.) are also acceptable.
1.7 Surface mould
Mould,causedbymicroscopicfungi,cangrowonwood,particularlyon
resinousspecies,onwhichthegrowthcanappearas“blueing”.Itisa
surface phenomenon, exacerbated by heat, humidity and inadequate
aeration and is characterised by stains ranging from light to dark blue.
Theycanberemovedbywipingthesurface.RememberthatclassIVtreatedwoodisprotectedagainst
attackbyfungithatcoulddestroythephysicalandmechanicalpropertiesofthewood.Formoredetail,see
the MyPool guarantees covering the species and the treatment.

1.8 Colour variations
Colour variations are common to every species of wood. Treatment
brings them out because the depth of penetration of the product
dependsonthewooddensityandgrain.Weatheringofwoodoutdoors
willsignicantlyattenuatethesecolourvariations.
!Duringstorage.Ifyoudonotintendtoassembleyourpoolimmediately,youshouldstoreitwithout
openingit,inawellventilatedroom,orfailingthis,inanareaprotectedfromtheelementsandsunlight.If
youhadtounpack,youmustrepackandrestrapthepallets.Oncethepalletsareundone,thewooden
structuremustbeassembledwithin24to48hours.
1.9 Curved wood
Duetotheconstantpressureexertedbythewater,thewallsofthepoolmaycurveslightlyovertime.
Thisphenomenon,attributabletothenaturalelasticityofwood,willstabiliseofitsownaccordandinno
waywouldleadtofailureofthewoodenslats.
Itisnotadefect,andwouldnotconstitutegroundsforaguaranteeclaim.
2. FOREWORD
Congratulationsonacquiringyourpool.Wehavetakengreatcarewiththedesignandmanufactureofyour
pooltoprovideyouwithatopqualityproduct.
The wood used to make the various elements (interlocking walls, coping, ladder, etc.) was carefully
selected.Outdoors,thesewoodenelementsaresubjecttoconstantweathering:contactwiththeground,
temperaturevariations,exposuretosunlight,rainandfrost,insectattack,etc.Thewood’sabilitytowithstand
thisaggressiondependsontheoriginofthewoodandthemethodusedtotreatit.
Forthisreason,wechoosepinefromextensive,sustainablymanagedforestsinnorthernEurope.Whydo
weinsistonthis?Becausethemorerigorousclimatesabovethe57thparallelfavourveryslowtreegrowth,
makingthewoodstrongerandmoreresilient.
Thewoodisautoclaved,thisinvolvessubjectingthewoodalternatelytopressureandvacuuminorderto
drivethetreatmentchemicalsintotheheartofthewoodasopposedtoothermoresupercialtreatment
techniques such as soaking.
ClassIVtreatedwoodincontactwiththegroundisimmunetoinsectattackandrottingcausedbyhumidity.
Autoclavetreatmentisguaranteed10years,inaccordancewithstandardscurrentlyineffect.
ThepoolcopingismadeoftreatedPINEplanks.
Wood is a living material, variations in temperature and humidity can cause it to expand or contract so take
caretofollowthestorageandassemblyinstructionsconcerningthewoodenstructure.Similarly,prolonged
exposuretoUVlightcancausewoodtogrey.Thesearenaturalphenomenathatinnowayeffectthe
service life of the products.
Donotapplyanyproducttothewood(forexample:lazure,micro-porousproducts,etc.).

5. SITING & PREPARATION OF THE GROUND
FOR OCTO AND OCTO + POOLS
Thisisthemostimportantstepintheprocedureasthepoolsitewilldeterminetheservicelifeofyourpool.
Therearesomerulesthatmustberespected.
Giventhevastvariationpossible(slope,typeandhomogeneityoftheground,possibleissueswithdrainage,
etc)wecannotproviderecommendationsforeverypossiblepermutationhere.Someoptionalsteps,such
as pouring a concrete slab, laying foundations, footing, laying drains, etc will require assistance from
professionalswhowillbeabletoadviseyouonsolutionsbestsuitedtoyourconguration.
Wewillexplainhowtopreparethegroundwithoutanyconcrete,theobjectivebeingtoachieveaat,level
bearingsurface.Inasfaraspossible,avoidsitingyourpoolundertrees(tostopyoupoolfrombeinglled
withleaves)ornearrisesordipsinthegroundthatcouldexposechildrentodanger.Donotassembleyour
poolunderelectricalcables.Thepoolshouldbeatleast3.50mfromanyelectricalsource(Frenchsafety
standardC15-100).Onaslope,neverbackllunderyourpooltobringthebearingsurfacelevel,always
cutintotheupwardslope.
Lastly,avoidpreparingthegroundandassemblingthepoolwhileastrongwindisblowing.
Howshouldthepoolbeoriented?
Ideally, the pool shouldbeorientedsothattheskimmersarefacinginto the prevailing wind.This will
determinethenalorientationofyourpoolandthemannerinwhichitwilllieinyourgarden,notablyinthe
