Protecting Britain's Infrastructure
Britain's roads, railways and bridges are under constant attack, not from traffic alone, but from the invisible, relentless forces of water, chlorides and freeze-thaw cycles that erode concrete from within. Across thousands of motorway bridges, major rail projects including HS2, and critical national infrastructure, one product is setting the benchmark for long-term protection: Epicuro HP Silane II.
Unlike traditional surface coatings that merely sit on top of concrete, Epicuro HP Silane II penetrates deep into the substrate — up to 50mm — thanks to its uniquely small, nano-sized molecules, some 20 times smaller than those found in conventional Silane/Siloxane products. This means protection isn't just on the surface. It's built into the structure itself.
"Protection isn't just on the surface — with Epicuro HP Silane II, it's built into the structure itself."
Where most competing products achieve only Class I performance under EN1504-9, Epicuro HP Silane II delivers Class II — the highest classification for hydrophobic impregnation. This is made possible by an exceptional formulation containing more than 95% active ingredients, compared to the diluted blends typical of the market.
Why it matters for national infrastructure
The cost of concrete corrosion to the UK economy is enormous. Chloride ingress from de-icing salts alone is responsible for the premature degradation of thousands of road bridges every year. For major projects like HS2 — where structures must perform reliably for decades with minimal maintenance intervention — the specification of the right protective treatment at the outset is critical.
Epicuro HP Silane II stops water, chlorides and dissolved salts from penetrating concrete surfaces, halting the electrochemical process that drives reinforcement corrosion. It also inhibits alkali-silica and alkali-aggregate reactions — a major cause of structural deterioration in older British bridges. And because it is non-film-forming and fully permeable to water vapour, treated structures can continue to breathe naturally, preventing the build-up of internal moisture pressure.
Chloride barrier
Blocks the ingress of chlorides from de-icing salts and marine environments, protecting steel reinforcement from corrosion.
Nano-molecule penetration
20× smaller molecules than standard silane products allow penetration up to 50mm deep into dense concrete.
Breathable protection
Non-film-forming formulation allows water vapour to escape, preventing moisture entrapment and maintaining structural integrity.
Rapid return to service
Effective within hours and overcoatable after just 4 hours — minimising disruption on live infrastructure projects.
Permanent protection, from the ground up
For the engineers and specifiers responsible for Britain's infrastructure, durability and whole-life cost are paramount. Epicuro HP Silane II delivers both. Its colourless, solvent-free, non-flammable formulation is safe to apply, leaves no visible residue and requires no specialist equipment beyond a brush or low-pressure sprayer. Application rates of 400ml/m² per coat, with one to two coats typically sufficient for most exposures, make it a cost-effective solution at scale.
In the most demanding environments; coastal and marine tidal zones, where chloride concentrations are highest, three or more coats can be specified for uncompromising protection. Epicuro's Approved Applicator scheme ensures that treatment is always carried out to the highest standards, backed by full technical support from our team.
The result is permanent protection that extends the serviceable life of concrete structures, reduces whole-life maintenance costs and helps the UK meet its infrastructure investment goals.
When it comes to protecting Britain's bridges, tunnels, car parks and railways, Epicuro HP Silane II doesn't just meet the standard, it sets it.
