Precast Concrete Septic Tanks

We maunfacture and install our precast concrete tanks throughout Northern Ireland and the South of Ireland. Unlike plastic and fibreglass alternatives, our precast concrete tanks are strong, durable and watertight. Furthermore, due to the nature of precast concrete, our tanks gradually strengthen over time. This is the reason why we can offer a 40 year structural warranty on our tanks. This is something you wont get from plastic or fiberglass tanks.
