debris and dust. Soak area with water and remove excess surface water. Apply a slurry
coat of Xypex Concentrate at the rate of 1.5 lb./sq. yd. (0.8 kg/m2) to the slot. Allow
slurry to reach an initial set, then fill cavity with Dry-Pac. Compress tightly into cavity
using pneumatic packer or block and hammer.
2. Rock Pockets, Honeycombing or Other Defective Shotcrete: Rout out defective areas to
sound concrete. Remove loose materials and saturate with water. Remove excess surface
water and apply a slurry coat of Xypex Concentrate to area. After slurry has set,but while
still"green",fill cavity to surface level with non-shrink grout.
SWIMMING POOL CONSTRUCTION 131 1 13 -20
Forest River Outdoor Recreation&Nature Center BH+A Project No. 3374
Salem,MA November 16, 2020 Addendum No. 01
B. Wetting Shotcrete: Prior to application of waterproofing treatment, thoroughly saturate
concrete surfaces with clean water as required to ensure migration of crystalline chemicals into
voids and capillary tracts of the concrete. Remove free surface water before application.
C. Construction Joints: Apply Xypex Concentrate in slurry form at a rate of 2.0 lb./sq. yd. (1.08
kg/m2) to joint surfaces between concrete pours. Moisten surfaces prior to slurry application.
Where joint surfaces are not accessible prior to pouring new shotecrete, consult manufacturer
for application procedure.
D. Sealing Strips and Coves: Prepare concrete surfaces that will come into contact with sealing
strips and coves by applying one coat of Xypex Concentrate in slurry form at a rate of 1.5
lb./sq. yd. (0.8 kg/m2). Then apply Xypex Concentrate in Dry-Pac form (sealing strip) or
Xypex Modified in mortar consistency (cove) after slurry coat has reached an initial set but is
still"green".
1. Sealing Strips: Where indicated on drawings, fill preformed grooves, one inch (25 mm)
wide and minimum of 1.5 inch (37 mm) deep, located at construction joints with Xypex
Concentrate in Dry-Pac form. Compact Dry-Pac tightly into groove using a pneumatic
packer or hammer and block.
2. Coves: Where indicated on drawings,trowel apply and pack Xypex Modified mortar into
a cove shape.
E. Surface Application: After repairs, surface preparation, treatment of construction joints and
sealing strip placement have been completed in accordance with manufacturer's product data
and as specified herein, apply Xypex treatment uniformly to concrete surfaces with semi-stiff
bristle brush or broom, or suitable spray equipment. Application rates and locations shall be as
indicated in the drawings and in accordance with manufacturer's product data. When brushing,
work slurry well into surface of the concrete, filling surface pores and hairline cracks. When
spraying,hold nozzle close enough to ensure that slurry is forced into pores and hairline cracks.
1. First Coat (of one or two coat application): Apply Xypex Concentrate slurry coat to
locations indicated on drawings in accordance with manufacturer's product data.
2. Second Coat (of two coat application): Where indicated on drawings or as required by
manufacturer's product data, apply Xypex Modified slurry coat while first coat of Xypex
Concentrate is still "green" but after it has reached an initial set. Use light prewatering
between coats when rapid drying conditions exist.
3.22 CURING
A. A. General: Begin curing as soon as Xypex coating has hardened sufficiently so as not to be
damaged by a fine spray. Cure Xypex treatment with a mist fog spray of clean water three
times a day for 2 to 3 days, or cover treated surfaces with damp burlap for the prescribed
period. In warm climates, more than three sprayings per day may be necessary to prevent
excessive drying of coating.
B. Air Circulation: Do not lay plastic sheeting directly on the waterproofing coating as air contact
is required for proper curing. If poor circulation exists in treated areas, it may be necessary to
provide fans or blown air to aid in curing of waterproofing treatment.
C. C. Holding Structures: For concrete holding structures such as swimming pools, reservoirs,
water treatment tanks and wet wells, cure Xypex treatment for three days and then allow
treatment to set (air cure) for 12 days before filling structure with liquid. For structures holding
SWIMMING POOL CONSTRUCTION 131113 -21
Forest River Outdoor Recreation&Nature Center BH+A Project No. 3374
Salem,MA November 16, 2020 Addendum No. 01
hot or corrosive liquids, cure waterproofing treatment for three days and allow to set for 18
days before filling.
D. Protection: During the curing period, protect treated surfaces from damage by wind, sun, rain
and temperatures below 36oF (2oC). If plastic sheeting is used for protect- ion, it must be raised
off of waterproofing coating to allow sufficient air circulation.
E. Curing Agent: If moist curing is not possible, use a chemical curing agent that is specifically
designed for or compatible with the approved crystalline waterproofing treatment. Curing agent
shall have at least two years of successful field use and shall be approved by waterproofing
manufacturer in writing.
3.23 POOL FILLING
A. After plaster and quartz finish is exposed, let it air dry for as long as conditions will allow.
Delaying the fill water a few hours or until the next morning to reduce the occurrence of shade
variations (mottling).
B. Dose water with recommended additives during filling and according to finish manufacturer's
written recommendations.
C. Dissolve all chemicals in water first and allow sufficient time for each chemical to be fully
dispersed before adding additional chemicals. Do not add chlorine or calcium chloride.
D. Start the circulation system as soon as possible using the main drain line. Circulate the water
continuously for the first 3 days.
E. On the first day test, adjust and record chemistry as follows:
1. ph :7.2—7.4
2. total alkalinity 100 ppm
F. Brush the entire surface twice each day for the first 3 days.
G. On the second day,repeat chemical adjustments and brushing.
H. On third day, adjust all the chemistry to the following levels:
1. ph :7.4
2. free chlorine: 1.0-3.0 ppm
3. total alkalinity 120 ppm
4. Calcium Hardness 200 ppm
5. Stabilizer 30-90 ppm
I. Coordinating dosing with Section 131510
