SoluForm’s preformed concrete bags can be used to create retaining structures away from watercourses.

SoluForm's high strength structural mix is designed to form a long-lasting, durable concrete block, suitable for a range of underpinning, scour protection and river walling objects.

The dry mix bags are hydrated on site.

Applications

  • Structural underpinning of abutments and training walls subject to scour

  • Formation of scour protection within watercourses

  • Creation of pipe, culvert or bridge headwalls and training walls

  • Formation of river walls, including repairs to existing walls

  • Creation of SuDS schemes, to create storage lagoons, etc

  • Earthwork retention

  • Embankment stabilisation works

Features and benefits

  • Simple to use - no specialist skills required

  • Can be carried and placed by hand

  • Highly adaptable system

  • Design mix options available

  • Allow placement of concrete in most cases without the need for dewatering or temporary works

  • Safe and environmentally acceptable

Credentials

  • EPD (Environmental Product Declaration) certified by BRE

  • Carbon Offsetting

Installation

Prefilled bagwork is hydrated prior to or during placement. If placed with intention of wetting in situ, SoluForm recommend that each row is placed and wetted individually. Water soluble liner will begin to dissolve in 5 seconds and is typically fully dissolved within 15 seconds. 20kg bag will absorb around 4L of water during this process, so have a ready supply of water.

Each bag placed horizontally. Place bagwork flat and build up in rows, alternating or cross bonding. Cross bonding improves the strength of the finished concrete bagwork. Bags can be patted flat or shaped once placed, to improve appearance and reduce voids within the finished work.

Steel rebar pins can be pushed down vertically after the second row to tie all the blockwork together. Steelwork is not always needed for above water bagwork but is recommended for medium to long term works.

If a temporary bath is used to soak the bags, any left over water should be disposed of in a safe and environmentally safe manner. The water will be high PH and should not be discharged into any watercourse.

Design Guidance

Soluform have a number of standard concrete bagwork wall designs for both in-water and non river applications. These are backed up with design calculations, risk assessments and design check statements and can be supplied upon request.
