The poly-wrap around the boxes is to be slashed prior to placing polythene overlay. Minimise the traffic over the boxes where possible and use planks over them for heavy traffic areas to reduce chance of surface puncture. Use bar chair plates (min 200 mm diameter) under bar chairs to distribute the load of the reinforcement prior to placement of the concrete. Care should be taken when pouring concrete so that concrete is placed evenly over boxes and not dropped or heaped in one spot to minimise excess loads. Concrete should not be poured from heights greater than 400-450 mm. If any doubt on the bar chair loading, increase the number of bar chairs. Take care when applying construction loads so damage to the boxes, by dislodging and distortion of the internal partitions and external covers, is avoided. Note: boxes MUST be installed and concrete poured as soon as possible, preferably the same day. Any time delays could jeopardise the satisfactory use of the material. Any boxes that are damaged or become wet during and after installation must be replaced. It is important to remember that concrete should not be poured over void formers if they are not dry or in good condition. Limitations Eccovoid void formers are designed for a particular purpose and sometimes delays to construction may be necessary to accommodate the nature of the product. When contractors are using void formers, they should remember the product limitations and take great care and consideration during construction to avoid problems. Customers should satisfy themselves as to the suitability of the product for its intended use.
