Description
Prefilled Above Water Bagwork is designed for the hand placement of concrete, above the waterline or away from watercourses, where external water is not present to hydrate the contained inside the bag. Uses typically include the formation of headwalls to culverts and bridges or the creation and protection of riverbanks, but in controlled situations can also be used for teh creation of scour protection, the filling of voids and for underpinning. Containment of the cement fines is provided by the addition of a water soluable liner inside an outer hessian bag. The concrete contained within the bagwork, remains inside the bagwork product during it’s use with the outer hessian bag acting as the external formwork. The concrete mix within the bags typically hydrates within several hours, hardens fully within 12 hours, and achieves full design strength within 28 days.
