Jones Construction Company and their, Subcontractors are responsible for forming. placing aggregate, grouting and curing of cement pressure grouted area, the epoxy pressuring grouting for sealing cracks and the surface preparation and topping and finishing of top surface as required by this procedure.

TOP SURFACE PREPARATION .

6.0 PROCEDURE 6.1 J. A. Jones Construction Company Engineering shall map the surface of the entire pour delineating the areas that can be made to meet the required elevation and finish by grinding and the areas that must be chipped out, to sound concrete and topped.

6.2 The areas requiring chipping and topping shall be chipped down to a minimum

' of one and one-half Inch (ly") below required elevation.

?

.<- l 6.3 After chipping to sound concrete and prior to any topping or grinding of other area, J. A. Jones Construction Company Engineering shall notify Ebasco Engineering that the, area is ready for inspection. Any area containing ,

unsound concrete shall be Inspected by the Windsor Probe method. In ver-Ifying the concrete soundness, the equivalent average 28 day compressive strength shall not be less than 5000 PSI and none of the equivalent com-pressive strengths shall be less than 4600 PSI.

p,. 2 6.4 Areas requiring grinding only to produce an acceptable surface shall be ground with suitable grinding machines until acceptable by the Engineer.

,t. ) 6.5 The surface of the chipped out area shall be cleaned and free from standing water, then coated with a neat coat of Sika Hi-Hod Epoxy mixed and applied per manufacturer's requirements. J. A. Jones' quality Verification to verify and document the acceptance of epoxy fnatcrial as to shelf life, mixing and application. .

g.; 6.6 After neat coat of epoxy, place 4000 PSI CJ, ass AA Concrete using paa gravel as coarse aggregate to required elevation and finjsh as required by approved construction drawings.

6.7 After the required finish has been obtained,'c'ure per requirements of Reference 4.1 and 4.4

7.0 PROCEDURE 7.1 PREPARATION 7.1.1 Determine area to be repaired. Area shall be determined by estimating workable area that can he worked, based on " pot life" and required cooling time if repair requires more than one Inch (1") thickness, Reference 7.3.2.

7.1.2 Clean area to be worked as follows:

7.1.2.1 Chip to sound concrete.

7.1.2.2 Surface must be dry.

7.1.2.3 Remove all dust, Iaitance, grease, and other foreign ,

particles, p

7.l.3 Straighten and support waterstop as required.

7.2 MIXING -

7. 2.1 Mix Sikadur-Hi-Mod Gel two (2) parts epoxy per manufacturer's recommendations. Amount to be determined by area to be worked.

7.2.2 Measure Colma Quartzite Aggregate and mix one (1) part Sika-HI-Mod Gel epoxy to one (1) part quartzite Aggregate. Add aggregate slowly to binder while mixing.

7.2.3 Do not attempt to use af ter " pot life" has expired. By adding

~

aggregate, it will add approximately five (5) minutes to " pot life".

73 APPLICATION ,

7 3.1 Apply prepared epoxy mortar to debed wat'erstop as required per attached sketch, Appendix A.

W 7 3.2 Apply mortar not to exceed one Inch (l") thickness. if required mortar thickness exceeds one Inch (l"), allow preceeding layer to cool before. applying second layer. Coolness can be determined

- when the mortar becomes hard, it should be cool, approximatel,y one (1) hour af ter mixing.

have a " slip r .pe" installed long enough to reach the extreme back of the void. Instal. the section of form over the deepest section of the void and extend "s. .p pipe" to reach the extreme back of the void. Pack tha void around tl " slip pipe" with vashed aggrggate until the angle of repose causes the ag; egate to fall out front of void. Instcil the bottom section of form with ; out nozzle located at extre=e bottom of void. Completely fill void witt aggregate (No. 4 to 1 inch, conforcing to ASTM-C-33) camp to ensure pro; ir packing, wat down aggregate, and install sections of form until entire sild is packed and' wetted. Top section of form must provide vent at top or void, and extend approximately six inches (6") above to

moisturc int.onsitivo cpoxy adhosive SlKA CHEMICAL. / LYNDHURST. N. .J. 07071 DESCRIPTION Sikadur Hi-Mod is a loot-solids, 2-component, moisture-insensitive, epoxy-resin sys tem. It is an all-purpose, high-strength, rigid adhesive designed for structural bonding of dry, can't-dry, damp, or wet structural materials free of standing water. Especially suitable for bonding fresh plastic-portland cement to sound hardened concrete, or, when mixed with granules, to prepare a high- '

strength grout to level base plates and to anchor bolts.

ADVANTAGES

. Unique, non-polysulfide bondins adhesive - - Sikadur HL-Mod is a polysulfide-free adhesivo for ' gluing' piastic concrete to hardened cr.increte. ,

. High-strength adhesive for *can't-dry

• surfares - - Exclusive formulation.

Patented curing agent makes Hi-Mod insensitive to moisture before, during, and after cure. Reduces need for job shut-down due to wet conditions. .

. Exco11ent adhesive for grouting bake plates and anchering bolts - - When mixed with granules, Sikadur Hi-Mod produces a high-strength grout for base plates and to-anchor bolts.

surface Preparation - - Con rote Surface must be clean and sound. It may be dry, *'

e damp, or wet, but free of standing water. homove dust, laitance, grease, curing compounds, impregnations, waxos, foreign particles, and disintegrated materials by mechanical abrasion methods such as sandelasting. S:eols Sandblast to appropriate '

finish. 9 Proportioning /Mixini - - Volumetric ratio of Sikadur Hi-Mod is 1:1 (B A). To ,

mix, proportion i part D and 1 parts A into clean pail. Mix thoroughly for 3 '

minutes with Sika paddle on low-spoed (400- to 600-rpm)Idrill until blend is a uniform straw color. Mix only that amount of Hi-Mod that you can use in 25 .

i minutes at 73r. ,

Application - - To prepare a grout to anchor bolts or levol base plates, mix Hi-Mod with Sikadur Granules. The amount of granulis used should be the maximum amount possible while still maintaining a pourable consistency. The ratio should be approximately 1:1% by loose volume (Hi-Mod: Granules). See technical bulletin on anchor bolt grouting and grouting base plates.

LIMITATIONS

.DO not thin Stkadur Hi-Mod! solvents will prevent proper cure.

Use only oven-dry granules to avoid encapsulation of moisture. Exposure to temp-eratures (af ter cure) above 180F (dry) and 120r (wet) not roccamended. Substrate temperatuse must not be below 40r.

a :: a moisturc inconsitivo cpony adhesivo DESCRIPTION SHf A CHEMICAL / LYNDHURST. N. .J. 07071 Sikadur Lo-Hod LV is a loot-solids, 100%-reactive, 2-component, moisture-insensitive, epoxy-resin system. Its low modulus of clasticity provides greater 'give' under stress due to impact and thermal change. Excellent for epoxy-mortar floor toppings and patching on dry, can't-dry, damp, or wet structural materials that are free of standing water. LV's also an efficient penetrating impregnation to seal dry porous substrates.

ADVANTAGES

. Unique, low-modulus adhesive for *can* t-dru* surfaces - - Patented, exclusive formulation of Lo-Mod LV makes it insensitive to moisture before, during, and after cure. Reduces need for job shut-down due to wet conditions.

. Zaspact , thermal-resistant toppines, pat:hes, overlays, grouts - - Lo-Mod LV has an approximate minimum tensile strength of 3,000 pst and a minimum tensile along-ation of approximately 5% for greater 'give' under stresses of impact and thermal I change. '

. rffective sealer for dru, porous concreto - - Low viscosity (lightweight oil) 1 i

enhances penetration of cry, porous concrete. Also seals LV-mortar toppings.

Sika.Firstin1910.First today. Wi j.t:vp Sika was the first to develop quicksetting compounds. Back in 1910. WM*A 4'E OWiM Sika's leak-stopping products 'made it'...they solved problems , *5MW

'W* D7 'T "r" h!S5 But our original compounds-and the many materials that , 4 '!#* "!d '38f34l%13 copied them-often sacrificed long-term durability.to develop fast "'!* M tn set, a set kicked off by chloride , sulfate , aluminate-based "d@@ 'A""N tecelerators. Consequently, the average ciuickset was often M'"~e M inadequate for demanding applications. It could fail after a few " E'A 6 **" ' Y#

freeze / thaw cycles; exposure to sulfate caused early disintegration. U"@. .'"-

MATERFORD STEAM ELECTRIC STATION 1980 - 1165 MW INSTALLATION - UNIT NO.'3 CCNCRETE REPAIRS FOR PLACEMENT 499S02 - 10B Attached is' a revised sketch (SK CH-163, Rev.1) detailing the extent of waterproofing required on the west face of foundation block 10B. Note

t. hat the waterproofing should extend below the effcceed area or to the top of the pleistocene whichever is lower. For ease of construction the

, reglet is to be cut horizontally into the concrete.
