SealProof Corp Capabilities

Ten ways to keep water out of a commercial building.

From the cold joint at the footing to the parapet at the roof, SealProof self-performs the full envelope. One sub. One contract. One COI.

How we work

Most envelope failures start in the detail, not the membrane. SealProof reads the drawings before mobilization, walks the substrate before primer, and stays on the manufacturer's procedure. Slower than the cheap bid — and the reason clients keep calling.

01. Below-Grade

Foundation Waterproofing

Below-grade leaks are the most expensive to fix — by the time water shows up in the cellar, the path back is from the inside, at three to ten times the original cost. SealProof installs spray-applied and sheet-applied systems on positive-side new construction and remedial excavation. Inspection happens before primer. The system goes in at full thickness.

Manufacturers
GCP · Henry · Aquafin · Penetron · Soprema · Sika · Polyglass · Tremco · Barrett
Typical Scope
Foundation walls, slabs-on-grade, elevator pits, retaining walls, tank exteriors. Projects up to 150,000 SF.
02. Above-Grade

Building Envelope

The envelope is the system the architect designed and the GC has to make watertight in the field. Every transition is a potential failure point. SealProof installs the envelope as a continuous system — air barrier ties cleanly to membrane at the parapet, flashing at the window, seal at the slab edge — with a photo log on every job for the closeout package.

Manufacturers
Henry Air-Bloc · Sika · Tremco ExoAir · Carlisle CCW · Prosoco · Polyglass · Soprema · GCP
Typical Scope
Above-grade air barriers, vapor barriers, joint sealants, flashings, and transitions on commercial new construction and major renovation.
03. At The Top

Roofing Membranes

Hot and cold applications. Modified bitumen, single-ply (TPO, PVC, EPDM), fluid-applied, and IRMA assemblies for plaza decks. SealProof is authorized across the full range — and meets every warranty requirement per spec, because the rep walks the work and the closeout is documented.

Manufacturers
Firestone Elevate · Sika Sarnafil · Tremco · Siplast · Soprema · Johns Manville · Polyglass · American Hydrotech · Kemper · Barrett
Typical Scope
New construction roofing, re-roofing, plaza deck waterproofing, IRMA assemblies, garden roof and amenity deck membranes.
04. Negative-Side

Chemical Grout Injection

Active leaks in occupied buildings, where the positive side of the wall is permanently inaccessible. Polyurethane or acrylate resin pumped through ports, expanded and cured to seal the leak path from inside. Specialty work — wrong resin in the wrong substrate makes the leak worse. We carry the rigs, we've trained the crew, and we'll tell you straight when injection is the right call vs. excavation.

Manufacturers
DeNeef/GCP · Sealboss · Penetron · Aquafin · ADCOS
Typical Scope
Active-leak repair on existing foundation walls, elevator pits, slabs, and below-grade mechanical spaces.
05. Integral

Crystalline & Cementitious Waterproofing

Permanent, integral protection that becomes part of the concrete. Crystals form in the capillaries and block water at the source. Used where long-term performance matters more than schedule — water tanks, sewage treatment, food-grade slabs, mission-critical mechanical rooms.

Manufacturers: Penetron · Aquafin · Prosoco  ·  Scope: Tank interiors, slabs, walls, structures where membrane systems aren't compatible with operating environment.

06. Continuity

Air Barrier Systems

Full continuity from grade to parapet. Fluid-applied, self-adhered, and mechanically-fastened systems compatible with the major envelope specs. The transitions are where most jobs fail — and where SealProof spends the time.

Manufacturers: Henry Air-Bloc · Tremco ExoAir · Carlisle CCW · GCP  ·  Scope: Above-grade commercial walls, mixed-use podium-and-tower assemblies, school and institutional renovations.

07. Joints

Expansion Joint Systems

Watertight, traffic-bearing, and fire-rated joint systems. The boring detail that protects every other system in the building — and the first to fail when installed wrong. Surface-mounted, recessed, and structural systems across walls, roofs, slabs, and plaza decks.

Manufacturers: Sika Emseal · Tremco Willseal · MM Systems  ·  Scope: Building-to-building joints, slab-to-wall joints, plaza-to-structure joints, and roof expansion joints.

08. Decks

Vehicular & Pedestrian Traffic Coatings

PMMA, urethane, and epoxy systems for plaza decks, parking structures, terraces, and amenity decks. Specified to the load, the exposure, and the re-coat cycle the owner can budget.

Manufacturers: Neogard · Sika · Tremco · Kemper · Siplast · Soprema  ·  Scope: Vehicular parking decks, pedestrian plazas, terraces, balconies, amenity decks.

09. Containment

Mechanical Room & Tank Waterproofing

Containment-grade waterproofing for boiler rooms, sump pits, water tanks, and elevator pits — where leaks become liabilities fast. Crystalline, polyurethane, and cementitious systems matched to the operating environment. Every coat and termination documented for closeout.

Manufacturers: Penetron · Aquafin · Sika · Tremco · CIM  ·  Scope: Boiler rooms, sump pits, water storage tanks, sewage treatment, elevator pits, electrical vaults.

10. Floor Systems

Epoxy & Urethane Floor Coatings

High-build epoxy and urethane floor coatings for industrial and commercial slabs. Chemical-resistant, abrasion-rated, slip-rated. Specified to the environment — laboratory, food production, manufacturing, parking, mechanical.

Manufacturers: NeoGard · Sika · Tremco  ·  Scope: Industrial floors, commercial kitchens, laboratories, mechanical rooms, parking decks, high-traffic public spaces.

Send us the drawings.

If you've got a project on the boards or in the pricing phase, the earlier we see the envelope drawings, the cleaner the bid comes back. We'll review the spec, flag detail risks, suggest the system that actually fits the building, and get you a number you can hand the owner.
