Under Slab


This pre-formed system can be delivered to your site in virtually any module size to fit any foundation or wall height required. With no cutting on site, you save both time and money.

Speed Form is constructed from wire mesh that is covered on both sides with a heat-shrink layer of polyethylene. Built structurally strong but lightweight, Speed Form is easy to handle on site. It is a very versatile formwork system that is ideal for radius applications and its installation is fast and easy.

The Speed Form permanent formwork system is the best alternative to traditional formwork methods, aimed at the construction of piles, foundations or R.C foundations with a bar reinforcement cage to pile caps and beams.

The Speed Form system is primarily for use ‘in ground’, but also has an ‘above ground’ capability when used in conjunction with additional system accessories.

Speed Form is supported by means of proprietary spacers attached to the reinforcement cage which transfer the backfill pressure onto it. When complete, the backfill material supports the Speed Form system during the concrete pour.

This guide is to illustrate typical Speed Form installation methods for most situations encountered when constructing pile caps and beams.

Our technical/support staff can provide detailed information for individual contracts. They can also provide on-site assistance during foundation construction.

The Speed Form system relies on the correct spacer application for support and to achieve the specified concrete cover to the reinforcement.
