The Tie Bolt Cones can be removed once striking of the formwork has taken place and the hole filled with the Formplug to produce a watertight repair to the surface of the finished concrete.   A flexible tight fitting plug for internal sealing of plastic sleeve prior to filling with tieplug filler.

Formwork & Plastic Plugs / Groove Caps & Plugs

Formwork Plugs are a  plastic plug for closing holes in formwork , Plastic plugs are inserted into plastic sleeve / tubing. The Groove Caps are closed with the Groove Plugs at both ends eliminating the need for rubber stoppers or cementation tie seal.

Surface Retarders

Top Face for Fresh Concrete  -  Mould Face for Shuttering

A non-inflammable pigmented retarder designed to produce an exposed aggregate surface which gives an excellent key for subsequent concreting or surface treatments. Ideal for construction joints and rendering application . Retarders are used mainly for two purposes:  1. Expose the aggregate to give a decorative finish to the exposed surface. 2. To provide a keyed surface for joining subsequent cast panels together without the need for scabbing or scarification. Our retarders are supplied in two forms: liquid (horizontal surfaces) and wax (vertical applications).

Column Formers

Bag Column formers are a single use of formwork system that gives an excellent smooth fair face surface finish. The column formers are manufactured by welding together several layers of high quality polyethylene. Once this is complete, a water resistant foil is also spirally wound over the kraft paper, sealing the column against humidity. This manufacturing process requires no additional adhesives which reduces the wall thickness, making the BAG Column formers light and easy to handle.  Maximum pour height for sizes below is 6 metres , we can supply column formers up to 1200mm diameter.    Column Former Data Sheet
