Description:
DRYCON is a waterproofing kit, containing portland cement, finely graded
mineral fillers, and chemical additives. The contents of the kit are mixed
with a measured amount of water to produce a creamy paste, or slurry. The
slurry is brushed or sprayed into the surface of the masonry or concrete.
The surface to be treated must be dampened so that the active chemicals in DRYCON
will be drawn into the pores.
DRYCON is a prepackaged, chemically active cementitious composition
designed to protect masonry or concrete from water induced chemical attack, and
to stop the passage of water through the material. A two coat application
of DRYCON is suitable for most interior below grade waterproofing
applications. Two coats of DRYCON will withstand hydrostatic
pressures up to 7 psi (16 ft. of water, 4.9 m), while three coats provide
protection to 45 psi (103.8 ft, 31.6 m).
DRYCON is not a paint. Although DRYCON forms a decorative,
non-flammable, inorganic surface for masonry or concrete, and although it is
applied with a brush or spray machine, it is not a paint.
Uses:
- DRYCON is used to prevent seepage of water through masonry/concrete
under pressure.
Advantages:
-
Double waterproofing protection by chemically
sealing the internal structure of the masonry or concrete as well as sealing
the surface with a dense, watertight cement coating.
-
Chemically interacts beneath the surface to
neutralize salts that cause efflorescence.
-
Cementitious material, offering indefinite life
expectancy and superior adhesion characteristics.
-
Integrates with the substrate and seals so
effectively that seepage can be stopped through interior application,
eliminating costly excavation and backfill operations.
-
DRYCON reacts chemically with the soluble
salts found in all cementitious building materials. DRYCON chemically
combines with these salts to form insoluble crystals, thereby attacking
efflorescence at its source.
-
A second chemical reaction occurs between the DRYCON
paste and additives, causing the paste to harden into a dense plaster.
In this way, an additional water barrier is created as a coating at the
surface of the masonry or concrete.
-
Non-flammable and can be applied without
specialized equipment or special skills.

Physical Properties:
Testing:
DRYCON
has been tested by using a modified hydrostatic test method ASTM C 497.
Porous pipe was lightly sandblasted to remove dirt and contamination. The
pipe wall thickness was 1.5 inches (3.8 cm). Pipe was thoroughly dampened
immediately prior to application of the first DRYCON layer. DRYCON
was brush applied to a thickness of 1/16 inch (1.6 mm). Material was mixed
to slurry consistency and brushed firmly into the substrate. The second
coat (White) was applied 1/16 inch (1.6 mm) thick to predampened pipe within 24
hours.
An epoxy gel sealant was applied to the bare ends of the coated pipe.
This section was immediately set into the cell restraints and bolts tightened to
firm pipe within. Assembly was allowed to cure for 72 hours at 65ºF
(18.3ºC).
Water was introduced into the cell bottom and completely filled the pipe, so
that water discharged from the top valve (vent). The air valve was then
opened and increased to 10 psi (69.0 kPa) over one hour. Pressure was
increased at the rate of 10 psi (69.0 kPa) per day thereafter.
Results: No leaks in DRYCON at 25 psi (172.4 kPa), seal
failure in pressure cell. Additional ASTM C 497 testing indicates repairs
to concrete pipe with no leakage to 30 psi (206.9 kPa) water pressure.
Yield: Coverage is an estimate only, actual coverage will vary
depending upon surface roughness and porosity. First coat coverage is
usually less than 100 square feet (9.3 m2) per kit, while the second
coat is greater. Average coverage for the two coat process is 100 square
feet (9.3 m2) per kit per coat of DRYCON.
Surface Preparation:
Surface to be repaired must be cleaned of any film, scale, loose material,
oils, grease and any other foreign material that will prohibit bond.
Surface preparation may be accomplished by accepted water blast, mechanical or
chemical methods. If acid washing is used, surface must be repeatedly
flushed with water to remove all trace of acid. Test with litmus paper to
confirm neutral or alkaline conditions. Thoroughly wet surface then allow
free water to run off.
DRYCON must be applied while surface is still damp. Failure to
prepare surface will prevent successful development of material physical
characteristics and will negate guarantee.
DRYCON must not be applied to surfaces from which water is seeping.
Cracks, voids, sizable holes, and localized points of leakage must be sealed
prior to treatment with DRYCON. Do not attempt to bridge cracks in
excess of 1/16th inch width. Consult sales engineer or product application
guide for other DRYCON system product recommendations and suggested repair
procedures.
Mixing & Application Instructions:
-
Open DRYCON kit. Thoroughly shake
enclosed plastic bottle until solid matter has liquefied and emulsion is
uniform. Mix contents of plastic bottle with 5 1/2 quarts (5.2 L)
clean water for each 50 lb. (22.7 kg) Kit. Rinse bottle with mixing
water to remove all of the additive.
-
Slowly mix the powdered materials into the water
and additive solution. Mix thoroughly to achieve a creamy slurry
consistency.
-
Apply slurry within one hour of mixing.
-
Saturate surface with water immediately prior to
application of DRYCON and allow excess water to run off. This
is extremely important: DRYCON will not give desired result
unless masonry surface is saturated with water.
-
Apply DRYCON by brush working material
into surface pores. If the DRYCON seems too thick for efficient
application, add a small amount of water (up to 1/2 quart (0.5 L) per kit)
to the mix.
-
Material may alternatively be spray applied
(using peristaltic or dual diaphragm pumps), but must be worked into pores
with a brush. Spraying tends to bridge pores and hairline
cracks. DRYCON must be worked into the surface for proper
result. Apply DRYCON at 1/16” (1.6 mm) thickness per coat.
-
DRYCON treatment is normally a two-coat
process. Second coat may be applied as soon as first coat has set,
(usually about 1 1/2 hours). When unusually great hydrostatic
pressures are anticipated, a third coat may be necessary. Two coats
will prevent seepage up to 7 psi (16 ft. of water, 4.9 m). Three coats
provide protection to 45 psi (103.8 ft. of water, 31.6 m).
Curing:
Curing of DRYCON is not necessary in closed underground structures
such as manholes and vaults unless strong drafts exist. DRYCON must
be cured if exposed to strong sunlight, hot or windy conditions. Water
mist periodically applied under draped poly or wet burlap will usually provide
the best curing conditions.
Clean-up:
Cleanup must be done immediately due to the high bonding characteristics of DRYCON.
Clean equipment with water.
Packaging:
DRYCON is packaged in 50 lb kits.
Limitations:
Do not install DRYCON unless substrate and air temperature is at least
40ºF (4.4ºC) and rising for the next 48 hours. Do not apply to a frozen
surface. DRYCON will not bridge cracks greater than 1/16 inch (1.6
mm). Material cannot be installed on surfaces that are actively seeping
water. Associated IPA products are designed for stopping leakage in
localized areas (IPANEX - R or OCTOPLUG PLUS). Consult
application guide or sales engineer for product recommendations and repair
procedures. DRYCON is designed for application on concrete or
masonry materials. DRYCON must be stored at above freezing temperatures.
CAUTION – FOR INDUSTRIAL USE ONLY:
Freshly mixed cement, mortar, grout, or concrete may cause minor skin
irritation. Avoid direct contact where possible and wash exposed skin
areas promptly with water. If any of the cementitious material gets into
the eyes, rinse immediately and repeatedly with water. If irritation
persists, obtain medical assistance.
