What IS a Subsurface Waterproofing Membrane?
When it comes to waterproofing, why settle for surface-level fixes when you can go straight to the core? A subsurface waterproofing membrane is an advanced protective solution that doesn’t just sit on the surface like traditional membranes. Instead, it dives deep into the pores of concrete, forming an impermeable membrane from within. Think of it as giving your concrete an internal force field—durable, long-lasting, and miles ahead of conventional methods.
How Does It Work?
Concrete is like that overly absorbent houseguest who soaks up everything you wish they wouldn’t. Left unchecked, it eagerly welcomes water through every crack, fissure, and capillary, leading to damage and inevitable deterioration. Subsurface waterproofing puts a stop to this nonsense. Our enzyme-modified formula dives deep into the concrete, forming a durable, invisible membrane that protects voids and cracks from water and harmful contaminants. The result? Concrete that’s dry, resilient, and ready to face whatever the elements—or your neglect—throw at it.
What sets this technology apart is its auto-regenerative superpower. Embedded with a bio-catalyst that stays active within the concrete, it doesn’t just sit there looking pretty. When new cracks form and water dares to intrude, the catalyst kicks into action, adapting and reinforcing the affected areas. This dynamic, self-renewing process ensures that the protective membrane stays intact, providing constant defense against water and other unwelcome elements.
And here’s the kicker: this membrane isn’t a surface diva like traditional coatings that peel, crack, or flake under pressure. It becomes part of the concrete itself, curing and drying from the inside out while leaving the surface looking natural and unbothered. By stopping leaks before they start and regenerating itself as needed, this system offers a sustainable, long-term solution that doesn’t just protect your structure—it outsmarts water entirely.
How Is It Applied?
Forget the complicated tools and processes. Subsurface waterproofing membranes are designed for simplicity and efficiency. Whether you have a low-pressure pump sprayer, a backpack sprayer, a drum-style sprayer, a roller, or even a standard paintbrush, you’re good to go. This flexibility not only makes the application process straightforward but also minimizes labor and equipment costs.
How Long Does It Last?
Here’s the best part: these membranes are built to last. Once applied, they’re in it for the long haul—designed to protect for the entire life of the structure. Say goodbye to frequent maintenance and costly repairs. With a subsurface waterproofing membrane, you’re investing in a sustainable, cost-effective solution that keeps your infrastructure intact and your budget in check.
Why Choose a Subsurface Waterproofing Membrane?
Subsurface waterproofing membranes are the superheroes of concrete protection. They don’t just mask the problem; they solve it from within.
Stops leaks before they start: Cracks stay dry, protected, and leak-free.
Protects better: Creates a long-lasting, invisible membrane embedded in the concrete.
Sustainable innovation: Certified VOC-free and non-toxic, because protecting the environment matters too.
Reduces costs: Fewer repairs and maintenance, more peace of mind.
Whether you’re working on a bridge deck, a below-grade structure, or any high-risk project, subsurface waterproofing membranes are the ultimate solution for enhanced performance and lasting protection. In short: it’s the smarter, stronger, and more sustainable choice for your concrete.
We’re not like the other girls.
Think of it this way: traditional traffic coatings are like a patchwork band-aid, while Alchemco’s waterproofing systems are a comprehensive health plan. Our solutions are spray-applied with minimal equipment, small crew sizes, and short downtime—saving you time, money, and headaches. Plus, your structure is open for business FAST, as our systems are trafficable within hours of application. No waiting, no fuss, just results.
Sealants are the glass slippers of the waterproofing world: they’re delicate, prone to cracks, and one misstep can shatter them. Alchemco’s systems, on the other hand, are the work boots—tough, durable, and built for the long haul. Our waterproofing integrates inside the structure, immune to mechanical or environmental damage, and delivers long-term protection that minimizes maintenance and repair costs. So, no matter how much wear and tear your structure faces, we’ve got you covered.
Absolutely, we handle that too! Spalling and corrosion are like the sneaky villains of structural deterioration—they show up when it’s too late to do anything about it. With Alchemco’s subsurface membranes, you can stop them in their tracks before they even make an appearance. Our systems prevent chloride ingress (the number one culprit behind internal cracking and rust), ensuring your structure stays strong and resilient. Because when it comes to spalling and corrosion, prevention beats repair every time.

Concrete Overlays - Polymer Based
-
Epoxy overlays are the most common overlay system in the U.S.
They are two-component systems, consisting of epoxy resin and a curing/hardening agent.
Known for their high bond strength and low shrinkage.
Often, no primer is needed if the concrete deck is properly cleaned and prepped.
Applied using a multiple-layer method, also called the broom-and-seed method.
Typically, 2-3 layers of epoxy are applied.
Aggregate (small particles) is spread on each layer as per the manufacturer's guidelines.
After each layer cures, unbound aggregate is removed before applying the next layer.
-
Two-component systems with polyester-styrene resin and organic peroxide as the initiator for curing.
Polyester overlays are usually applied using the premix method.
The material is screeded to grade for even application.
Fine aggregate is spread on the surface for initial skid resistance.
These systems generally require a primer on the bridge deck before applying the overlay.
-
Two-component systems with methyl methacrylate resin and a small amount of organic peroxide as the curing initiator.
Methacrylate overlays are usually applied using the slurry method, mixed with aggregates.
Both the bridge deck and aggregate must be completely dry due to the system’s sensitivity to moisture.
Methacrylate top-coats are available to help bond/encapsulate the aggregate.
Common chemistries used include Poly Methyl Methacrylate (PMMA) and Polyurethane Methacrylate (PUMA).

Concrete Sealers -Penetrants
-
- Concrete deck sealers are spray-applied liquids designed to cover the entire bridge deck, not just cracks.
- The most commonly used chemistries are Silanes and Siloxanes.
- These sealers penetrate the concrete surface and act as a water repellent (hydrophobic).
- They do not qualify as waterproofing products.
- They cannot seal existing or future cracks.
-
- Silane sealers penetrate concrete but may not be ideal for enhancing and fully protecting surfaces.
- They create a hydrophobic barrier, but their effectiveness is limited in harsh weather conditions.
- Issues like water penetration, freeze-thaw damage, and stains can still occur.
- While they offer some protection, they may not meet expectations for comprehensive or visually pleasing solutions.
-
- Siloxane sealers are known for their water-repellent properties, but their effectiveness is limited.
- They provide only partial protection against water intrusion, which can lead to cracks, pitting, and weakened structural integrity.
- These sealers often perform poorly in areas with heavy rain or constant moisture exposure.
- Durability is a concern, as siloxane sealers typically need frequent reapplication.
- Over time, the protective barrier fades, leaving concrete decks vulnerable to deterioration.
-
- Enzyme Modified Subsurface Membrane Waterproofing (EMSMW) provides long-lasting waterproofing for concrete structures.
- It penetrates concrete and forms a durable chemical bond with its minerals, creating an impermeable barrier against water intrusion.
- This bond is highly resistant to moisture and does not degrade over time, offering consistent protection.
- EMSMW has an auto-regenerative property that activates when minor cracks or voids form, reacting with water to seal them and prevent further damage.
- This auto-regenerative ability ensures long-term structural integrity and protection, lasting for decades.
- EMSMW stands out from traditional methods due to its chemical bonding and auto-regenerative capabilities.
