maintained.

.5 When ambient air temperature is at or above 27°C, or when there is a probability of

temperature rising to 27°C during placing period (as forecast by nearest official

meteorological office), protect concrete in place from effects of hot or drying weather

conditions. Under severe drying conditions (as defined by CSA-A23.1-09), protect

arrangement wherever possible. Form ties shall be evenly spaced and located in straight

horizontal and vertical lines.

irregularities in the finished concrete. In addition, deflection of facing materials between

studs, as well as deflection of studs and whalers, shall not exceed 0.0025 times the span.

.5 Construct forms so that finished concrete will conform to shape, dimensions, and

tolerances as specified in the Standard. Construct forms so that they may be dismantled

and removed without damaging concrete.

.6 Keep untreated forms moist to prevent shrinkage prior to placing of concrete and wet

surface at time of placing.

.7 Treated formwork surfaces shall have approved form coating applied in accordance with

manufacturer’s recommendations, prior to placing reinforcing steel. Remove excess form

coating.

.8 Forms shall not be removed until concrete has attained sufficient strength that no damage

to strength or continuity of concrete will occur when forms are removed.

.9 Prying against face of concrete to remove forms is not allowed; only wooden wedges shall

be used.

.10 Remove form ties carefully to avoid marking concrete and to allow for patching. Grout

and patch form tie holes.

3.4 FIELD QUALITY CONTROL

.1 Consultant will evaluate bonding of fresh patch material to existing concrete after fresh

patch material has cured sufficiently.

.2 Evaluation will be performed by sounding, using hammer-sounding or other techniques.

.3 Detection of hollow sound in any area shall be reason to suspect inadequate bonding and

each such area shall then be cored, as requested by Consultant, to determine bonding

adequacy.

.4 Cores will be visually inspected and further testing required, if any, will then be determined

by Consultant.

.5 Patch core holes.






3.5 PATCHING

.1 Repair and patch honeycomb, exposed reinforcement, and other defects at no additional

cost to Owner. Patching procedures, materials, and finishes shall subject to Consultant’s

review and approval.

required for construction purposes or cut back to depth of 38 mm from surface of concrete.

3.6 REJECTION OF DEFECTIVE WORK

.1 Where, in opinion of Consultant, materials or workmanship fail to meet requirements of

specification, such work or materials will be rejected. Replace or repair rejected Work to

approval of Consultant and at no additional cost to Owner.

.2 Failure of bond between topping and existing concrete at core specimen or failure of

compression tests will require additional core samples to be drilled at expense of

Contractor. Subsequent failure of these additional samples shall result in rejection of repair

areas represented.

blowing joint clean with compressed air (minimum 90-psi pressure, moisture-free, and

oil-free). After cleaning, prepared joints must be thoroughly dry and dust free before

sealing. Prepared joint surfaces shall have no signs of residual sealant, laitance, cement

powder, or dust after rubbing a clean cloth across joint faces.

waterstop. If existing waterstop is not present, install Polyethylene Closed Cell (Hard Cell)

foam similar to Item 3.3 EVA Compression Seal – Backer Installation - below prior to

installation of Injectable Conduit. Where feasible, do not prepare substrates or install

Closed Cell foam in moist or wet conditions. Do not use sharp tools to install Closed Cell

foam in order to prevent potential damage during install.

alongside joints, and vertical joint surfaces to depth of sealant. Ensure epoxy adhesive






materials are not applied to substrate surfaces to be subsequently bonded or adhered to

sealant materials.

.3 Adhere EVA compression seal backers with continuous, permanent, weatherproof

adhesive to both sides of joint. Do not introduce tension or stretching of EVA seal during

installation. Recess joint seal to accommodate depth of sealant materials.

– Heat-Welds, Splices, and Other Directional Changes – below.

3.4 EVA COMPRESSION SEAL – HEAT-WELDS, SPLICES, AND OTHER DIRECTIONAL

CHANGES

.1 Heat-welds, splices, and other directional changes should be cut and made prior to seal

installation.

.5 Align seal ends and apply pressure to cause ends of seat to slightly protrude upwards.

Allow approximately 3-4 minutes of cure time prior to releasing pressure.

3.5 SEALANT APPLICATION

.1 Apply sealant materials in accordance with manufacturer’s environmental and temperature

requirements. Do not install sealant when temperature is at or below dew point. Do not

install sealant when temperature is below 5°C. Do not prepare substrates or install sealants

if substrate surfaces are wet. Moist joint substrates shall be permitted to air dry (visibly

dry and to touch) prior to starting/continuing sealing operations. Drying joints with using

direct flame shall not be permitted.

.2 Apply sealant in accordance with manufacturer's directions complete with manufacturer-

approved primer and/or conditioner, using gun with proper size nozzle, to leave watertight,

airtight installation. Use sufficient pressure to fill voids and joints solid. Superficial

pointing with skin bead is not acceptable.

.3 Form surface of sealant smooth, free from ridges, wrinkles, sags, air pockets, embedded

impurities. Sealant to be continuous, free of air voids, and applied such that it fills voids.

Neatly tool joint to profile as indicated on project documents.

.4 Clean adjacent surfaces immediately and leave work neat and clean. Remove excess

sealant and droppings, using recommended cleaners as work progresses. Remove masking

tape after tooling of joints.

.5 Protect sealant joints until sufficiently cured. Protect sealant materials from dust, debris,

and construction materials.

.6 Application procedures that result in toxic fumes or flammable solvents collecting or

endangering workers or facility occupants are not permitted.

3.6 CLEAN UP

.1 Clean adjacent surfaces immediately, leaving work neat and clean.

.2 Remove excess sealants and droppings using recommended cleaners as work progresses.


.1 Periodic inspection of various phases of work will be performed by Owner. Provide safe

access in work areas.

.2 To ensure proper bonding of materials to substrate adhesion, tests may be performed, to

test for adhesion, thickness, and width by Owner’s appointed testing agency or Consultant.

.3 Repair test locations at no extra cost.
