We currently offer a 32N high strength structural mix within our bagwork products. 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. Our prefilled concrete bags are ideal for use in the construction of a concrete bag retaining wall.  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.     ![DJI_20260217073302_0029_D](https://www.soluform.co.uk/hs-fs/hubfs/DJI_20260217073302_0029_D.jpg?width=837&height=470&name=DJI_20260217073302_0029_D.jpg)       ### SoluForm Concrete Bag Benefits     Prefilled and ready to use.   Cost Effective.        Simple to Use. No specialist skills required.   No need to dewater area.   Time Saving - Hand Placed.   Consistent Size and Shape - 20kg bagwork.   Expected Guarantee of 120 years design life.  Saltwater underwater applications have an underwater pin.    ### Steelwork 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 driven down through the bags during installation and can also be used to securely connect the bagwork to adjacent structures, such as abutments or retaining walls. We stock standard sized 300mm long, 8mm thick U shaped, galvanised to BS EN ISO 1461: 2009 mild steel rebar pins that are suitable for use with our bagwork. A pin manufactured of marine grade 316 stainless steel is available for salt water/ marine applications.       ![Rebar Pin](https://www.soluform.co.uk/hs-fs/hubfs/Rebar%20Pin.png?width=243&height=260&name=Rebar%20Pin.png)                 #### Quick Links - [About](https://www.soluform.co.uk/about) - [Topsoil Filled Bagwork](https://www.soluform.co.uk/topsoil-filled-bagwork) - [Concrete Filled Bagwork](https://www.soluform.co.uk/concrete-filled-bagwork) - [Applications](https://www.soluform.co.uk/applications) - [FAQ](https://www.soluform.co.uk/faq) - [Downloads](https://www.soluform.co.uk/downloads) - [Benefits and Uses](https://www.soluform.co.uk/benefits-and-uses) - [Contact](https://www.soluform.co.uk/contact-us) - [Case Studies](http://content.soluform.co.uk/case-studies) #### Get in Touch Head Office: **01629 541066** [**sales@soluform.co.uk**](mailto:sales@soluform.co.uk) ##### Follow Us on Social Media: ![BSI ISO 9001](https://www.soluform.co.uk/hubfs/7599060/Images/BSI.jpg) #### Contact Us You can contact in several different ways; you can call us on: **01629 541066**, chat with us online by using the chat icon at the bottom right of the page, or send us an enquiry using the enquiry form on our 'contact us' page.
