Waterproofing 101: How UNISIL Products Protect Infrastructure
By Mane Grigoryan
Waterproofing often doesnât get the spotlight it deserves. Itâs not flashy. Itâs not something you show off. But ask anyone whoâs dealt with a leaking foundation, a crumbling bridge deck, or moisture-laden walls, and theyâll tell youâwaterproofing is everything. Itâs the quiet layer of protection that determines whether a structure weathers decades or falls apart in years.
Letâs take a moment to unpack how this works, and more importantly, how silicone-based systemsâlike the ones we develop at UNISIL in Hungary and the USAâplay a vital role in protecting infrastructure around the world.
To start, it helps to understand the enemy. Water doesnât just seep. It infiltrates, reacts, erodes, expands, corrodes, and often sets off a chain of failures beneath the surface. And infrastructureâwhether it's a road tunnel, rooftop, or industrial facilityâis constantly under siege. Concrete is porous. Bricks absorb. Steel corrodes. Even so-called âwater-resistantâ materials can degrade over time without the right barrier in place.
Thatâs where smart waterproofing systems come in. And for us at UNISIL, it begins with silicone chemistry. Unlike traditional sealants or films that try to block water with sheer thickness, silicone-based waterproofers work differently. They bond at the molecular level, penetrating the surface and forming a flexible yet durable network that repels water while allowing the structure to breathe.
That breathability matters. A lot. Because when moisture is trapped insideâsay, by an overly rigid membraneâit canât escape. Eventually, that leads to blistering, mold growth, or structural weakening from within. But silicone-based solutions strike a balance. They block out rain, snow, and humidity, yet still allow internal vapors to escape outward. It's like putting a raincoat on your infrastructure that also happens to ventilate itself.
Take our SL-11K waterproofing concentrate, for example. Itâs been used on rooftops, bridge decks, and even basement retaining walls. In one caseâan industrial warehouse in a flood-prone part of Hungaryâthe product helped reduce visible efflorescence and cracking in the exterior wall system within just one season. The client didnât change the substrate or layout. They just switched to a higher-performing barrier. Sometimes, itâs really that simple.
But thereâs more to it than just the chemical formulation. We think about how products are applied in the real worldâby hand, roller, or sprayer. We think about surfaces that might be hot or dusty or slightly uneven. Thatâs why formulation flexibility is key. Some clients want a fast-curing system for field work. Others need a low-VOC solution for enclosed or environmentally sensitive zones. And sometimes, it's both.
Waterproofing also isnât a one-size-fits-all discipline. Different environments create different challenges. A tunnel system in the Pacific Northwest deals with persistent damp and fungal growth. A parking garage in Arizona contends with extreme heat and UV degradation. The needs are different. But silicone technologies can be tailored, and weâre constantly working to improve those adaptations.
Of course, no discussion about infrastructure would be complete without touching on sustainability. And here's where things overlap in surprising ways. Longer-lasting coatings and sealants reduce the frequency of maintenance cycles. That means less material waste, fewer repair trips, lower energy consumption. Itâs the kind of âquiet sustainabilityâ that doesnât show up in marketing brochures but adds up, year over year.
That same spirit of forward-thinking is what brought us to the Go Global Awards. UNISIL is a nominee for the 2025 event in London, hosted by the International Trade Council. Now, I know what youâre thinkingâanother award ceremony. But this one is different. It brings together business leaders, trade experts, and innovators who are shaping what global commerce looks like in a rapidly evolving world. Itâs not just about trophies; itâs about connections. Ideas. Fresh momentum. Being part of that space matters, and weâre proud to represent both Hungary and the USA in the process.
Maybe the most rewarding part of our work in waterproofing isnât the chemistry itself, but the impact. The homes that stay dry. The bridges that hold firm. The public infrastructure that lasts just a little longer because something invisible is doing its job.
And maybe thatâs the whole point of waterproofingâitâs not there to be seen. Itâs there to protect. Quietly, relentlessly, without drawing attention.
Thatâs what we build for.
