2 Alpha Bloc NEW A4 pp 9/5/05 12:32 pm Page 3 Alfabloc The unique Alfabloc walling system is only available from us and has seven important advantages over any other traditional walling on the market today. 1 2 Easy Installation No other walling system can be installed as quickly. No Protruding Toe Allows easy cleaning and unloading. X No protruding toe to get caught on. 3 4 Freestanding No Ground fixing required in most cases. Load one side only or both sides. Delivered Upright 5 Bay Configuration 6 Bay configuration can be changed in minutes. Interlocking Blocks interlock to form solid wall. 7 Threaded Inserts 16mm or 20mm threaded inserts cast into block, for connecting or lifting.

3 Alpha Bloc NEW A4 pp 9/5/05 12:33 pm Page 4 Features & Accessories Accessories A unique and extensive range of accessories are available to complement the Alfabloc range. Roof Kits A range of roof kits are available, making covered storage an option with the Alfabloc walling system. Steel Extensions Increases 3m unit to 3.6m Corner Sections End Covers Lifting Attachment Indestructible Push Wall Corner sections allow Alfabloc walls to be continuous and gap free. End covers seal the wall units and are available in a variety of designs. The unique lifting attachment ensures ease of construction, making an Alfabloc wall a one man operation Pump hollow section with concrete to form a virtually industructible wall. Optional Ground Fixings Ground fixings are available for an even more secure surface attachment. Top Channel Standard cast in threaded inserts allow fixing of top channel. Recessed Connecting Straps Recessed connecting straps attach wall units together along their vertical length.

N.B. 3.05m & 3.65m are designed to be lifted using the horizontal cross member 1.4m above the base of the block and therefore no attachment is required Once in position lower the Alfabloc into place so that the connecting straps fit securely over the installed unit. NB: DO NOT attempt to install Alfablocs by inserting the unstrapped end of one unit into the strapped end of an installed unit. Alfabloc must always be lowered into place as described above. 3 Alfablocs are delivered upright on a flatbed vehicle. N.B. Some Alfablocs will be delivered without steel connecting straps fitted. 9 To secure Alfablocs in place, first loosen the bolts in the 2 connecting straps of the freshly installed unit. 4 These strapless units should always be used to begin installation of each new row of Alfablocs. This allows the first Alfabloc in a row to be placed flat against a retaining wall. 10 Align the holes in the front edge of the connecting straps with the holes in the previously installed unit. Insert bolts and tighten to secure the Alfabloc in place. 5 Always lift Alfablocs into position with the connecting straps facing away from the forklift i.e. towards the installed units. 11 Re-tighten the previously loosened bolts in the newly installed unit. 6 Align the Alfabloc with the previously installed unit. 12 Repeat the process (steps 5-11) until the desired number of units are installed in each row.

This allows Alfablocs to be placed at right angles to one another forming a secure sealed corner. (16) 15 Alfablocs fitted with corner sections are moved into position the same way as normal blocks fitted with connecting straps. 16 Position the corner unit against an existing Alfabloc wall and lower into position.

9 Alpha Bloc NEW A4 pp 9/5/05 12:3 pm Page 10 Applications The Alfabloc is a very structurally efficient and versatile concept in design. In the majority of working conditions the Alfabloc units are lowly stressed and provide a robust retaining structure. With granular materials, which generally provide the most onerous loadings, the Alfabloc unit has additional stability generated by the frictional force down the face of the wall. Experience has shown the units can withstand significant misuse by mechanical plant used to move retained material. However, as with any relatively thin walled concrete structure, they will suffer damage with persistent and negligent striking by mechanical plant. The foundation for the Alfabloc system is usually the new or existing concrete hard standing onto which stored materials will be contained. The loads imposed by the Alfabloc units are usually no more than the wheel loads imposed by the mechanical plant utilised to move the stored material. Depending on the nature of the stored material the units can be either placed onto the concrete hard standing or bolted into place. To assist in the spread of load horizontally the units are nominally fixed together with a galvanised plate, which also provides a seal to the joints.
