Heavy-duty membrane systems for tunnels, underground structures and water retention tanks.
Get Free QuoteTunnels, underground utility structures and water retention tanks operate under continuous hydrostatic pressure and are extremely difficult to access for repairs once complete, so the waterproofing system must be right the first time. We deploy heavy-duty PU and cementitious systems specified for underground and tunnel applications, following engineering specifications for critical infrastructure work.
A correctly applied Tunnel & Underground Waterproofing system typically performs for 7 to 15 years depending on material grade, surface preparation and weather exposure. Unicorn Chemical issues a written workmanship warranty on every project.
