5.4 REINFOR(ING STIEL

'$/herr applying Series 459 ot 479 t<l deep ot large horizontal area.s or vertical pours of polymer concrctc, suitable rcinforccments suclr as corrosion resistant rebal shoulcl be considered. Wl-ren rnaking large horizontal pours, applying the material in a "checkerboard" pattcrn can avoid hcat build-up and potential cracking fi'onr culing strcsses. When nraking hear.y pouts grcater than cight (8) inches (20 cm) in depth it is rccomrnended to consuh with Tnemec 'l'echnical Scrvices.

5.5 TERMINATIONS

I3elore beginning application, all tcrminations should be planned.

Tcrminations should bc madc into saw-cuts, kcying thc matcrial not less than Vz-inch (12.7 mm) depth. Expansion and control joints are to be provided on 14-foot (4.3 m) centers, around fixed objects at the pefiphery of the floor and/or at any existing expansion joint.

These joints shall have an appropriate sizcd closed-cell foam backcr rod inscrted and fillcd flush with'l'nemcc'lank Armor@ Scries 351 or othcr seruice-spccific, flexible chenrical-resistant compound. All perforations, gaps or other areas of expected movement or flex shall also rcceive an application of selcctcd flcxible linings fbr complete chcnrical reststance .

5.6 IRAMIN6

If walls, curbs or other vertical strllctures at'e to he pouled and cast ftom Series 469 or 479, formwork will need to be built to retain the polymer concrcte , Prior to assembly or ercction of the fornrwork lhe pieces shall be coverecl with hea\y plastic and or (xher suitable lelease agcnts to assist in preventing attachment of thc polymer concrctc to thcsc surfaccs. Vhcn casting into fbrnrs it is impcrativc that all joints ancl mating sudaces are complctcly sealed to prevent

Scries 459/479 from flowing out. All seals and joints must be tight cnough to hold watcr. Vhcrc forms mcct irrcgular surfaccs such as concrete, it is a good idea to place a hear'1' caulk bead or putty at this intelf-ace fbr additional "weep" resistance.

Prior to starting installation, pleasc note the fbllowing:

. Itcmize all materials ordcred {iorn Tnemec.

. E.stablish sut'face preparation t'erluirements.

. Ensure all equipment is readily available and in working ordcr.

. Sct-up a mixing arca clcarly dcsignatcd at lcast 5O fcct (15.2 meters) away from hcat, sparks, open flame, welding, or other sources of ignition.

. Comn-runicatc thc installation, safcty proccdurcs, ancl rcquircmcnts with all persons involved.

Note: Polyrner concrctes should never be pourecl, placed or grouted in direct sunlight, Further temperatulc conditions and protection tiorn rain and other elcments must bc assured prior to bcginning any preparation or application of thcse matel'ials. if necessary, tenting and introduction of conditioned air may be reqr.rired. Many timcs, a pop-up awning is sulhcicnt to protcct the arca lrotn ovcr-heating and/ol from the direct sunlight.

'Whccl barrows and othcr convcyancc cquipmcnt should bc lined with hearry plastic to aid in cleanup.

Erluipment and unmixed contponents should be placed as closc to thc application sitc as possiblc.

Large pro.jects should have a back-up mortar mixer on sitc.

Additional LavaCrcte Parts A, R or C may be ordered as needed to adjust batching and placement characteristics. Addinpi Part C will in-crease the stiffness and thc coverage rate. By decreasing the amount of Part C, thc flowability or fluidity of thc material will increasc, however the coverage late will be reduced. The following adjust-ments may be made in the ficld at tlle installer's discretion to the standard & fluid mix fbr-mulas fbund on the product data sheet and in this guideline to create a mix that is p|eferred by the applicator.

To make the matcrial heavier, add up to 70Lbs. G1.75 kg) in a large kit (1.K) or' 20 lbs. (9 kg) in a snrall kit (SK) of Part C. To rnake thc

7.9 SERIIS 469/419 LAVA(RETE WORl(ING TIME

\ilorking time is approximately 30 to 40 nrinutes at75P (24C') & 50% RIl. Note: Placement and finishing time is dependent on en-vironrnental conditions and temperature of components. Material should be transferred to suhstrate and placed imrlediately after mixing.

IMPORTANT: Do not attempt to letemper the polymer concrete with addilional resin or water. Matedal should be moved quickly from thc mixcl to thc arca of placcmcnt.

8.I sERIES 459/479 I.AVA(RETE MATERIAL TRANSIIR 'When the primel is ready (see Section 6.2), materials should have been appropriately mixed and moved to the placement location and the initial drops can bc made onto thc substrate.

Placement of the wet polymer concrete shall be from the transfer unit (wheel barrow or tub) and on to the substrate in a staggered drop fashion, If placed between screed guides, allow enor.rgh dis-tance between drops so the material will meet thc sides, rise up to the top of the rail and once pulled moving forward, each drop of material meets the previous dlop. Once a rhythrrr is established the transfer installel will know the screed applicator's preference for the location of cach drop.

If the area is small and no screed guides are in place, the material from a mixcd kit should still bc placccl in spaccd amounts to nrakc pulling or troweling of the material more manageable.

Unless a pour is more than rwo (2) inches (5 cm) in depth, it is never adviscd to drop all two cubic feet of material in one location.

"Specification fbf Installation of Epoxy Grouting Befi^'een

For:ndations and E<;uipnrent Bases" published by the American Concrctc Institutc (ACI). Ilcst practiccs ancl allowanccs arc dc-tailed, cspecially in Part J-Execution.

. Vhen grouting purnp/motor/enginc bascs or rail scttings, al-qr.rys use the "grouting" mix in lieu of thc "casting" fot'mula.

. The goal in vibration control and dampening is to have the grclut create a solid connection iiom thc ccluipment, through tlre baseplate to the fonndation antl finally into the soil: a tight and air-pocket-fiee fill is critical.

I O.O LAVA(RTTI GROUTIN6 INSTATLAIION

Anchor bolts, leveling screws and fbrrns should always be in-stalled by cxperienced grout pcl'sonncl.

Polymcr conclctes are not uscd for "groutillg" bctween tiles as thc aggrcgatc sizc is too larllc.

Typically, an API compliant or other baseplate ol bedplate is sct on top of a ncs/ or in good condition concrctc founclation or pad.

If the concrcte is a ncw pollr it must be adequately cured prior to bcginning this rvork. If an cxisting fbundation is to bc uscd, chcck fol cherrrical contalttination, larease or oils and remove priol to nre-chanically cleanit-tg thc suriace to accept Series 469/479.

To achievc a good bond of the polynrcr concrete to the concrete foundation, the surface should be chipped using a pneumatic or air drivcn chipping hatttmer to expose no lcss than 5OVo of'the ag-grcgatc. 1'his irregular surt:rcc should not have pockets or holes any deeper than the ^ggreg lc itself as thesc cavitics can potentially hin-dclthe flow ol the grout and/or create air pockets. Additionally, the paramcter' of thc concretc pad shal! be chamfeted dot'n to providc a greater depth of thc grout matcrial along the edge of the pad. Al1 chips and dust shall bc blown clcan with oil-frcc dry ail and with thc assistancc of heavy- bristlc blushes.

IO.2 IAVA(RIIE GROUTING FRAMIWORK

Forms should be constructed in accordance with ACI 301 "Specifi-cations fbr Structural Concrctc." In gcneral, a fiamework fbrm shall bc' cleated around the prcparccl concretc pad and tightly affixecl to the outside parameter. This framcwork should be fabricated out of :/<-inch plywi-rod and/or 2x4 or '2x6 str-aiglrt studs, and all gaps or cracks caulkcd or putty-filled to retain grout nlaterial. The intcrior sides shall be hcavily waxed or petrolatum-bascd 'lubricatcd with thick paste to facilitate the releasc of the forms once tltc grout has set. In gener:rl, thc top of this containnrent franrewolk, slrould have a height level to the baseplate at the following corresponding levcls:

Engine franre platcs: a nrinimum of 1 inch (2.5 cm) below the top of the plate Rail or solcplatcs: a minimttm of Yz inch (1'.27 cn-t) from thc bottom of the plate.

Skid "1" beams: over the flangc and up the web a minirnum % lnch U.l/ cm).

NOTE: In order to fix a morc accuratc hcight of thc gt'tlut contain-ment frame, it is usually placed after the sctting and leveling of the baseplates or rails.

IO.3 LAVA(RITE GROUTING BASEPLATE

Tlrc baseplate shall be prepared by abrasive blasting the intcrnal side to SSPC-SP6 Commercial Blast ot'better. 'fhe cxterior side of the plate should also be abrasivc hlasted to remove paint whelc thc grout is specified to meet the metal.

Equipnrent alignment, levcling of plates including adiustnrent screws and anchor bolts and expansion ioints are tl-re responsibil-ity of thc owncr's installcr. Thc contractor should bc familiar with best-ptactice procedures and have expedence in these disciplines.

Lcvcling scrcws for thc bascplatc should havc thc bottorn of thc screw resting on a leveling pad that underneath ha.s had this small area filled with a quick setting lcvcling compound. I'ad should have a 3-inch (7.6 cm) diamctet'and be gluecl to the preparcd founclation substrate to offset twisting.

Anchol holt jackets/sleeves placed in the concrete foundation shall protrude slightly above the foundation and receive expansion joint compound betwecn the jacket and sleeve.

l'hc anchor bolt sleeve to bc surroundcd by Lava(iletc sllall be plo-tcctcd from thc grout by placing foam pipc insulation picccs (At'-maflex or similar) of a matching size, diameter and length around thc shaft. Spray-applicd urethane ioam nray also be uscd.

It should be confirmed that appropriatc vent holes have becn re-movcd pliol to pouring grout.

I 0.4 I.AVA(REII GROUTING APPLI(ATION

It will be ncccssary thzlt some typc of funncling or "hcadbox" bc fabricated to as.si.st in grouting application. Depending on thc loca-tion and configuration of the foundation top to bc flrouted thc box fbr concentrating tlrc pour may need to bc lairly largc. For small haseplatcs with fill holes up to threc (3) inches (7.6 cn't) in diameter, many times a plastic traffic cone with a smooth interior and the tip r:ut off to allow flow is sufficicnt, The hcad box ot cone should always be al an elevation above the highcst point of tl-rc pout. Matcrial placcd in thc hcad box or funncl should never bc allowc'd to fall below the highcst point of the grout fill as air or pockets will bc introduccd when these gaps occur.

Uninterruptcd filling of thc head box/funnel to maintain hydraulic pressurc or head prc.ssulc should bc rnaintaincd fbr maximurn flow-ability and push of thc grout.

. Grout should cnter through a singular inlet of the baseplate at one end and flow until it has rcachcd an adjaccnt inlct. Move headbox ol funnel to that inlet and continuc grouting until complcte .

. If grouting using a lance or lrose, it should be insertcd under the plate to the point ftr|thest from extraction. The lancc/hose shall be withdrawn as grout is pumped, keeping it cmbedded in the grout at all times.

The outer perimeter edges of the surface pour shall be |elieved with a 45" chamfcr strip.

Lavacrete should bc pour-ed from one side of the casting only; this hclps to avoicl air cntrapmcnt. It is important that thcrc is vcnting available at the opposite end of the pour; this allows air to move out of thc fbrm as the polymcr concrcte is bcing pourcd.

If expansion joints are necessary, thc following at'e guidelines:

. Expansion ioints must be situatcd from thc top ol tllc grout to the bottonr meeting the concrete base ot pad.

. Expansion joints should bc placed every 3-7 feer (7-2 m), iso-late each grout plate or rail fiom each other and run the lcngth of the pour.

' Pour grout into adjoining expansion ioint areas once the previ-ous cxpansion joint is at least 50Vo f'ull of grout.

. They may be madc flom rigid Styrofoam or hald rubber or othcr non-oi1 absorbing material.

. An altcrnatc n-rcthod is to plastic wlap wood strips and pour the grout around them at thc desired expansion ioint locations.

Once the LavaCrete has firmly sct, these strips al'e removed and fillcd with an appropriatc chcmical-rcsistant flcxiblc loint material.
