Submerseal is uniquely suited
to sealing joints in swimming pools. This installation in a 12-foot
hydrostatic head condition at a waterpark illustrates installation.

Submerseal installation begins with preparing and cleaning the
concrete joint faces of any protrusions, contaminants and old sealant. The
concrete on either side of the joint is masked with duct tape.

Epoxy adhesive, supplied with by EMSEAL as
part of the system is mixed and applied to the joint face. The
Submerseal is removed from it precompression packaging and begins to
slowly self-expand. It is immediately inserted into the wet-epoxy on the
joint faces and pushed into the joint until the crown of the bellows is
recessed just below the surface of the concrete.
Corners and joins between lengths are joined
with field applied silicone. Each successive length is pushed firmly
toward the previously installed length in order to create longitudinal
pressure at the joins to prevent gaps.

A sealant band of silicone supplied by EMSEAL as part of the system is
injected between the Submerseal and the joint faces. The overburden is
firmly tooled into a corner bead between the silicone bellows and the
concrete joint face.

With the duct tape removed the Submerseal installation is
complete. In order for the material to resist hydrostatic
pressure, at least 7 days of cure time is required before the pool can be
filled. |

Standard sizes in 1/4"
(6mm)
increments from 1/2" to 4"
(12mm to 100mm).
Movement Capability
+25% and -25% (Total 50%) of nominal material size.
Color
Submerseal's standard color is "white". Custom colors are
possible but color can impact hydrostatic head capability--consult with
EMSEAL.

at concentrations typically found in swimming pools, fountains, water
parks, etc. including normal and intermittent maintenance "shock"
concentrations.

Product Description
Featuring a convex silicone-bellows sealing surface and backed by an
integral, pressure-resisting impregnated foam backing, Submerseal
provides a lasting solution to joint sealing applications where constant
exposure to chlorinated water is expected.The system is comprised of
precompressed, silicone-and-impregnated-foam hybrid installed into
field-applied epoxy adhesive on the joint faces with the silicone
bellows locked to the joint faces with a field-applied silicone sealant
band and corner bead.
|
Features
Watertight —
Submerseal is installed with the convex, tensionless silicone
bellows facing the liquid ensuring that watertightness is achieved.
Non-Invasive Anchoring — there are no hard metal-to-substrate
connections with Submerseal. This includes embedded pins,
anchors, screws, bolts or tracks, trays or rails. The system is locked
to the joint faces by means of the 1) backpressure of the foam; 2) the
epoxy adhesive, and 3) the field-injected silicone sealant band and
corner bead at the joint face to foam-and-silicone bellows interface.
Applicable Standards: The silicone coating is
compliant to NSF/ANSI Standard 61; NSF Standard 51; FDA Regulation CFR
177.2600; MIL-A-46146; and UL 94 Flame Class, 94 HB.

|
Performance
Substrates must be solid, parallel, plumb and free of any contaminants.
IMPORTANT--Cure Time After Installation: Submerseal cannot resist
hydrostatic pressures stated unless a minimum of seven days is
allowed for the injected silicone sealant bands and corner beads to
fully cure. Cure time can vary based on environmental conditions.
It is the responsibility of the installer to monitor cure. |

Composition
•
Submerseal is
produced by coating an impregnated cellular foam with a non-corrosive
liquid silicone sealant.
• The external
silicone facing is factory applied to the foam at a width greater than
the maximum offered extension and is cured before final compression.
• The silicone
application and curing takes place in a factory-controlled environment.
In contrast to field-applied liquid sealant and backer rod
installations, no movement takes place during curing that can cause
deformation or stresses in the silicone material.
• When
compressed, a convex bellows is created in the coating. As joint
movement occurs the bellows simply folds and unfolds virtually free of
tensile stress in the silicone material.
• The foam provides a
resilient backing to the silicone coating, making the system capable of
resisting head pressure.
• Submerseal is supplied in 6.56 LF
(2m)
shrink-wrapped lengths (sticks). Submerseal is
precompressed to less than the joint size for easy insertion. After
removal from the shrink-wrap and hard board restraining packaging, it
expands gradually.
Installation
IMPORTANT: The following instructions are a summary. Refer to "Submerseal
Install Data" and/or job-specific instructions of an EMSEAL technician
for complete procedures. FOR PROFESSIONAL USE ONLY. KEEP OUT OF REACH OF
CHILDREN.
• Store indoors at room temperature. Expansion is
quicker when warm, slower when cold. Substrate temperature must range
between 40°F (5°C) and 110°F (43°C).
•Precautions: Wear chemical-resistant gloves and/or barrier
hand cream when handling liquid sealant or epoxy. Remove materials
promptly from skin with a commercial hand cleaner before eating or
smoking. Avoid inhaling vapors.
•Sequencing: Install factory-fabricated
transition and/or termination pieces first. Connect straight run
material to in-place terminations and transitions. Cut closing pieces
3/8-inch (10mm) longer than the opening to be joined. Compress material
longitudinally to fit.
• Ensure nominal material size matches field measured
joint size.
• Mix epoxy and trowel a thin layer onto the joint
faces to at least the depth of the
Submerseal
foam.
• Remove shrink-wrap packaging and hardboard.
• Thoroughly wipe and clean the silicone facing using
clean lint-free rag made damp with water.
• Insert material into joint to determined depth
below the substrate surface.
• On the end of the material apply a band of liquid
silicone along the pre cured bellows’ faces.
• Join lengths by pushing silicone-coated ends firmly
together. Always push, never pull while installing this material.
If you stretch the product it will shrink back from the joins resulting
in leaks.
• Before the epoxy or the silicone cures, force the nozzle of the
caulking tube between the foam and the substrate and inject a minimum
1 1/4"
(30mm)deep
silicone sealant band,
measured
from the crown of the bellows. Firmly tool the overflow sealant into a defined
corner bead between the top of the silicone bellows and the substrate.
• Clean Up: Remove epoxy or silicone sealant from
equipment before it cures using MEK*, Toluene*, or Xylene*. These
solvents are not effective after the epoxy or silicone has cured. Cured
material may be removed by cutting it away with sharp tools or
sandpapering.
*(Solvents mentioned or referred to are toxic and
flammable. Observe solvent manufacturer’s precautions and refer to
Material Safety Data Sheets as well as local and federal requirements
for safe handling and use)
IMPORTANT:
Allow liquid silicone to attain a complete cure before filling area with
liquid (7 days minimum).
Note: if the silicone at joins, sealant bands and corner beads is
not allowed to fully cure, the system will not be capable of resisting
hydrostatic pressure.
• Maintenance: If the silicone bellows or sealant bands
are damaged but remain intact, cut out the damaged area and recaulk. No
primer is required. If the bond has been affected or the foam backing of
the Submerseal
is compromised, remove the damaged area, clean and prepare the
substrates in accordance with instructions and reinstall new material. |
