Unfortunately not. Although we previously sold empty bagwork for self-filling, SoluForm bagwork is now only available as a filled bagwork product.

We stock a standard size rebar pin that is suitable for our range of bagwork. This is a 300mm U shaped galvanised rebar pin formed from mild steel rebar, and they are available for immediate despatch. Other diameters, lengths, shapes and types of steel rebar can be sourced, however, lead times for cutting and bending, followed by galvanising, can mean lead times of around three weeks for steelwork other than our standard sized pin.

Powdered anti-washout additives are generally an ineffective safeguard with dry mix placement in watercourses. Anti-washout additives (plasticisers) mixed within a dry mix concrete, only activate when the dry mix has been hydrated, creating a plasticised concrete that resists the escape of the cement fines from the mixed concrete. Almost all the risk in placing hand placed concrete in a watercourse comes from accidents or careless activity prior to being placed, and during this period the mix is fully dry. A dropped or torn bag at this stage will still shed its powdered contents irrespective of an additive or not. Water to hydrate the concrete is only introduced once the bagwork has been placed in its intended position, although at this stage there is then no movement in the bagwork likely to result in leakage, as long as the use of steelwork follows our general guidelines for installation. The liner is there to provide a barrier between the contents inside the bag and the surrounding water, in effect, the liner replaces the need for an anti-washout additive.
For Unlined Bagwork, anti-washout additives can be added if required, subject to minimum order quantities and sufficient lead times.

The use of steelwork is prescribed in the Product Specification literature. The seal between the bags and the pins, combined with the way the steelwork is used, ensure the use of steelwork remains clean

Due to the bulky and heavy nature of the prefilled bagwork, together with the need to ensure the product stays dry during transit, deliveries are via haulier using curtain sided haulage vehicles. The most cost effective and typical way to deliver is by 24T articulated lorry, although there is the option to deliver smaller quantities with smaller curtain sided vehicles.

Should you have any preference, please state at the time of enquiry so that suitable haulage options can be investigated.

Delivery may be made with or without tail lift and it is important that consideration be made to your off-loading capabilities at the place where they are to be unloaded. Where tail lifts are not possible, deliveries will need to be offloaded with a fork lift or telehandler. Where tail lifts are available, offloading can be completed with the vehicles pallet truck, onto a suitable, level hard standing area. It is therefore important that consideration be made to the offloading capabilities on site, and whether it is safe or practical to do so.

Of course, though the customer should ensure that the delivery address is easily locatable and accessible for a third party haulier. The customer should also ensure that the site delivery address is capable and safe for accepting haulage vehicles. Generally, we recommend all orders are delivered to a fixed, manned, permanent delivery address, such as a depot, which are easier to locate and more suited to haulage vehicles and offloading.

The buyer accepts responsibility, costs and all risks relating to losses or delays arising from deliveries requested to temporary site addresses and associated unloading problems.

Small quantities (up to 5 pallets and usually from stock) are typically possible within 2-3 working days, otherwise please allow up to 7 working days for delivery. For orders over 30 pallets, please allow several weeks as they are typically filled to order. We recommend contacting our sales department as early as possible to ensure we can meet your timescale for delivery, and to reserve stock.

The introduction of water to harden the concrete is a major consideration and important it is made before ordering the type of bagwork. SoluForm Lined bagwork is suitable for placement below water, with the use of steelwork. It relies upon the surrounding river or seawater to harden the concrete. When bagwork is to be placed out of the water or away from a watercourse, consideration needs to be made to where the water to harden the concrete will come from. For schemes where bagwork is placed outside the watercourse, and when environmentally acceptable to do so, unlined bagwork can either be pre-soaked or wetted following placement. Please see the individual Product Specifications for further information.

This depends upon where the bagwork is to be placed. Consideration should be given to where the water can be introduced to harden the concrete, and the associated environmental risk in doing so.

Lined bagwork is suitable for placement in the watercourse, where the surrounding water becomes absorbed by the dry mix, to harden the concrete. When using lined bagwork, steelwork is used to pierce the bagwork, allowing water to absorb into the bag and hence hydrate the dry mix concrete. For placement in water, the biodegradable liner is needed to ensure the placement is clean and environmentally acceptable.

Unlined bagwork can be useful in situations where the environmental risk can be mitigated, or simply isn’t there. Often for works away from the watercourse, like ditch work, risk is manageable or even negligible. Unlined bagwork can be pre-soaked prior to placement, or often the bagwork is hosed down after placement such that the concrete is hydrated and can harden.

We offer two grades of mix with our prefilled bagwork in both line and unlined bag options.

Our structural mix is a 32N limestone:cement concrete mix and is suitable for all forms of structural bagwork including underpinning, scour protection, culvert headwalls and river walls. The high strength creates a long lasting, durable concrete block with a longer design life and works particularly well with steel reinforcement.

Alternatively, for price conscious schemes or where technical performance is not required, we also supply a 12N dry mix, suitable for void filling and general bagwork. The specification for this dry mix is comparable to an ST1 (7.5N) or Postmix concrete (8-12N). The Contractor should satisfy himself/herself as the suitability of the grade of concrete supplied, for the application in hand.

Prefilled bagwork is palletised and sold per Tonne, with each prefilled bag holding 25kg of dry mix concrete. Each pallet therefore contains 40no. prefilled bags and this will be sufficient to complete just over 0.5 cubic metres of finished bagwork. Bagwork is typically estimated in cubic metres, so to complete each cubic metre of concrete bagwork, assume that 2no. pallets of prefilled bagwork are required.

All our bagwork is now supplied prefilled with dry mix and arrives ready to use. We supply both SoluForm Lined and Unlined bagwork, factory filled with 25kg of dry mix concrete. Both 32N and 12N concrete mixes are available in lined and unlined options.
