Simple, Clean & Environmentally Acceptable

Soluform Bagwork

SoluForm Bagwork is available pre-filled and arrives ready to use.

We currently offer a 32N high strength structural mix.

The high strength structural mix is designed to form a longer lasting, durable concrete block, suitable for a range of underpinning, scour protection and river walling projects, and works particularly well with steelwork. This structural mix is typically used for schemes specified by Consultants, for more technically demanding schemes, or where there is a need for a longer design life. The high strength mix is available in both the underwater and above water bag options.

Patented Biodegradable Liners

Underwater bagwork utilises SoluForm’s patented biodegradable liners and enable dry mix concrete to be placed below water, with the use of steelwork, in a clean and environmentally acceptable manner. Alternatively, our water soluble above water bagwork can be useful for dry or out-of-water bagwork applications, or for schemes where either the environmental risk isn’t there, or the risk can be managed. In the absence of surrounding water, above water bagwork is hydrated by either pre-soaking or hosing in situ, dependant upon where the bagwork is placed.

The important considerations when selecting the type of concrete are Function and Design Life. The temptation is always there to put in a low strength, low durability, cheaper concrete mix but the consequence is ultimately a poorly performing bagwork construction with a short design life.

For high value or vulnerable assets, we recommend always repairing and protecting with structural grade concretes.


Steelwork should be included to tie the individual blocks together, helping to create a large singular block of concrete bagwork. Steelwork is important in schemes where protection against scour is needed, or the design life of the blockwork needs extending, to prevent individual blocks from being dislodged.

Steel rebar pins are pushed down through the bags during placement, and can also be used to tie blockwork to other structures, like abutments or retaining walls.

We stock standard sized 300mm long, U shaped, galvanised mild steel rebar pins that are suitable for use with our bagwork. Other thicknesses, sizes and grades of steel can be provided on request, given sufficient lead time.
