Description :

Prefilled SoluForm Underwater Bagwork is designed for the hand placement of concrete in watercourses. Uses include the creation below water of scour protection, void filling, underpinning to a structure subject to scour, the formation to underwater parts of headwalls to culverts and bridges, or the creation and protection of riverbanks and walls below water. The concrete contained within the bagwork, remains inside the bagwork product during its use, with the outer bag acting as the external formwork and the inner liner as the means of concrete containment. Both the inner liner and outer bag are fully biodegradable, safely biodegrading insitu within 6-12 months. The concrete mix within the bags typically hydrates within several hours (refer to instructions below), hardens fully within 12 hours, and achieves full design strength within 28days.
Each prefilled SoluForm Underwater Bag is supplied filled with 20kg of dry mix high strength structural concrete, 50no. prefilled bags per pallet, with each pallet shrink wrapped for storage and protection. Prefilled U/W bagwork can be placed underwater with the use of galvanised steel rebar pins, the pins being used short term to pierce the liner and allow water to hydrate the concrete, and long term as a means of linking blockwork together into a singular massive block of concrete blockwork.
