Faster, Longer-Lasting Shoreline protection.
Settlement shifts ground. Erosion strips defences. Left unchecked, both weaken dams, rivers and coasts. Concrete holds the line, but it’s slow, brittle and carbon heavy.
Hydraulic asphalt is different. It's flexible, 75% more sustainable than concrete and proven underwater. Since 1986, we’ve used it across the UK to protect critical infrastructure from erosion and flooding. From feasibility and design to installation, inspection and maintenance, we deliver end-to-end protection for dams, reservoirs, spillways, rivers and coasts.

Smarter Solutions for Hydraulic Protection.
Our erosion systems sustainably deliver strength at speed, and our technology provides long-term solutions where traditional methods fall short.
Stop Erosion & Scour
Seal & Protect Reservoirs
Reinforce Rock
Protect Against Subsea Impact
Engineered asphalt systems that stabilise riverbanks, estuaries, coasts and offshore structures. Flexible and durable, they resist fast flows and wave energy to safeguard assets from long-term degradation.
Hydraulic linings for dams, reservoirs and spillways. Proven to reduce leakage while extending the service life of water-retaining structures.
Grouted rock systems that bind and reinforce existing armour stone. Adds flexibility, reduces required rock size and upgrades protection against high wave loads and scour.
Specialist asphalt applications placed below the waterline. Designed to protect structures from scour, impact and high-velocity flows - installable underwater with minimal disruption.
