Allen Block commercial by Caroline James

Allan Block is the ultimate concrete masonry retaining wall system in Australia. The superior colour range and versatile nature of the various components allows designers, architects and engineers to specify with confidence. The aesthetic finish of Allan Block compliments the entire range of C&M paving, architectural masonry and other retaining wall systems for a total design solution in projects of any scale. Allan Block walls require no structural foundation and lock together without pins, clips or mortar. The front lip creates a built-in setback and the hollow core makes them easy to handle, easy to stack and promotes built-in drainage. With a diverse range of colours, sizes, components and a choice of both standard and pitched face finishes, and available in five natural colours, the scope to create stunning walls is limitless.

Terraces In some cases it is preferable to terrace a site rather than construct a single wall as this allows for garden beds and stairs between levels to be incorporated into the landscape design. Although terracing improves the look of the landscape, it is important to consider the pressure of the upper wall on the lower wall. The distance between the walls must be greater than 1.5 times the height of the lower wall to ensure the top terrace does not apply loads to the lower wall. This does not take into account global stability issues which need to be considered. Terraced hillsides may require engineering assistance. Contact your C&M Representative for more information.

ALLAN BLOCK THREE OATMEAL

ALLAN BLOCK AUSSIE BONDI BLEND

Whether you select gentle curves or classic straight lines, Outside Curve

the Allan Block will satisfy every architectural design. Curved and serpentine

walls are easy to build and accent natural landscape forms. To build external curves, remove one or both block wings as you lay the blocks. Consider how tight or gentle you want the curves to be and choose the block or combination of blocks that are best suited for your wall layout. Outside curves are achieved by knocking the lugs off the back of the block.

Inside Curve

Concave and convex curves can be easily built using the Allan Block system. For setback walls a slight coning will occur on curved walls. Design curved walls so the radius at the top of the wall is at least 1.2m. Refer to table 1 to find the minimum recommended radius at the wall base while maintaining a 1.2m radius at the top of the wall.

Use this chart to find the minimum recommended radius at base of wall. Table 1: AB Radius Chart Figure 2: Angle Curve v Soft Curve

Angles Angles require precise cutting and therefore soft curves are more frequently incorporated into designs.

Helpful Hints Try to build away from corners and avoid small block cuts at the corners. Soft corners are easier to build than angles.

Figure 3: Remove wings for Outside Curves

Figure 3: Removing Wing from Back of Block Try to maintain at least 75mm of the block length offset on the lower block as you build curves. Perfect “running bond” is not necessary with Allan Block.

Corners When building corners start from the corners and build away. Always avoid small cut blocks at the corners.

Internal Corners Internal corners are constructed using standard Allan Block units. Remove part of the front lip with a chisel or saw and overlap for a strong interlock as detailed in fig 4.

External Corners External corners are easily constructed using Allan Block corner units. Each course of cornerstones should alternate between a left and right hand corner unit. Corner units must be ordered as left and right hand units otherwise a straight 50/50 split will be delivered. Note: Colour variation may occur between the corner units and face units due to the manufacturing process. Remove lip

Steps Many variations of step designs are possible. Step layout for rise and tread needs to be calculated with consideration to the stair tread that best suits your application. Steps can be designed with flowing curves or with right angles. The simplest step designs are built using curves and save time as no cutting of blocks are required. Allan Blockâ&#x20AC;&#x2122;s patented front lip provides a built-in edging that works well with the matching capping units, C&M pavers, poured concrete, crushed rock or mulches. Ensure the step treads are secured in place for safe use. Tread

Segmental gravity walls are based on 0.8 factor on the vertical component of soil friction, for both permanent and imposed soil and surcharge loads. Important: Please consult with the appropriate council for local design and construction of a retaining wall. Councils in general require that retaining walls be designed and certified by a suitably qualified engineer where the wall is over 500mm in height and/or where there is a load such as a road, driveway, house, building or hydrostatic pressure.

Construction Guidelines - Gravity Walls Width = 600mm Depth = 250mm for base plus embedment required as per step 2.

01: Excavation Excavate a trench 600mm wide by a mimimum 250mm deep (This allows for a 150mm leveling pad plus 100mm minimum block embedment). Walls over 3m high will require greater embedment.

02: Leveling Pad Fill trench with road base material and compact to 150mm using a mechanical plate compactor. Alternatively 10MPa unreinforced concrete can be used.

03: First Course Base Material

02 Level each block side - to - side & front - to -back

Use a 1.2m level or line level to check the entire base course Position string line at the back of AB Units

Place the first course of blocks onto the leveling pad and align with a string line at the rear of the units. Check blocks are level side to side and front to back tapping with a rubber mallet to make adjustments. It is advisable to allocate considerable time to ensure a level base course. Sand or mortar can be used as a leveling aid.

04: Install Drainage Materials Locate the agricultural drainage pipe behind the wall parallel to the wall face, with a minimum fall to the drainage outlet of 1:100. Fill all voids within the blocks and the area 300mm behind the blocks with clean 12-20mm drainage material to the top of the first course.

05: Backfilling and Compaction Place backfill behind drainage layer. Using a vibrating plate compactor running parallel to the wall, compact the backfill always working out from the wall. If backfilling area is to be left unfinished overnight, ensure final layer is compacted with a slight fall away from the face of the wall.

Fill Drainage Material in blocks & 300mm behind wall

06: Additional Courses 04

Brush the top of the block to remove excess material. Place the next course of blocks and level side to side and front to back. Repeat steps 3-5 until wall is at finished height.

07: Capping If capping is required, it is suggested that the caps are secured with a cement based flexible adhesive.

Allan Block segmental retaining walls utilize their shape and weight to resist the lateral earth pressures. They are inherently free draining due to the dry-stacked construction and granular drainage layer immediately behind the wall. Walls below 800mm can generally be classified as gravity walls. Higher walls need to be designed with soil reinforcement that is placed in between layers of compacted backfill. The length, location and grade of the geogrids are determined by calculations based primarily on the following: Surcharges acting on wall (including live, dead and/or seismic) Heights of wall Soil characteristics (retained, foundation & backfill) Materials (type of reinforcement, data available, etc) Standards Australia has published AS4678 for the design and construction of earth retaining structures. For further assistance on the design or specification aspects of retaining walls, please contact your local C&M representative. As a guide, the tables on the next page illustrate typical geogrids layout for the specified site conditions.

Construction Guidelines - Reinforced Soil Walls

ALLAN BLOCK THREE OATMEAL

01: Bulk Excavation Excavate in accordance with the specific design requirements, allowing enough depth to accomodate the reinforced geogrid zone.

02: Excavation Excavate a trench 600mm wide by a minimum 250mm deep. (This allows for a 150mm leveling pad plus 100mm minimum block embedment). Walls over 3m high will require greater embedment.

03: Leveling Pad Fill trench with road base material and compact to 150mm using a mechanical plate compactor. Alternatively, 10MPa un-reinforced concrete can be used.

04: First Course Place the first course of blocks onto the leveling pad and align with a string line at the rear of the units. Check blocks are level side to side and front to back tapping with a rubber mallet to make adjustments. It is advisable to allocate considerable time to ensure a level base course. Sand or mortar can be used as a leveling aid.

05: Install Drainage Materials Locate the agricultural drainage pipe behind the wall, parallel to the wall face, with a minimum fall to the drainage outlet of 1:100. Fill all voids within the blocks and the area 300mm behind the blocks with 12-20mm clean drainage material to the top of the first course.

06: Backfilling and Compaction After placing drainage material in the block voids and 300mm behind the blocks, place a 200mm layer of approved backfill material on top of the geogrid. All drainage material in the drainage field and infill soils within 1.5m of the wall must be properly compacted using a walk behind plate compactor. Compact in maximum 200mm lifts, starting on top of the wall and working in a path that runs parallel to the wall towards the back of the reinforced zone (Figure 11). Compacting equipment should not make direct contact with geogrids. All heavy equipment must be kept at least 1.2m from the wall face.

07: Geogrid Cut sections of geogrid to specified length. Place geogrid over the block lip and extend back into the reinforced soil zone. Place the next course of blocks on top of the geogrid. Pull taut on the geogrid to remove any slack. Stake geogrid in place before installing drainage and backfill material.

01: Excavation Excavate a trench 600mm wide by a minimum 250mm deep. (This allows for a 150mm leveling pad plus 100mm minimum block embedment). Walls over 3m high will require greater embedment.

02 Levelling Pad Place 25 MPa concrete to a depth of 150mm and width of 600mm.

03 First Course Place blocks onto the leveling pad and align with a string line at the rear of the units. Check blocks are level side to side and front to back tapping with a rubber mallet to make adjustments. It is advisable to allocate considerable time to ensuring a level base course. Sand or mortar can be used as a leveling aid.

04 ‘No Fines’ Concrete Backfill Fill the voids of the block and backfill to the specified depth with ‘no fines’ concrete. The vertical height of pour should not exceed 600mm. Allow each pour to set prior to laying and pouring subsequent courses. Alternatively the wall may be propped. Note:

Remove rear wings of block to ensure mass ‘no fines’ concrete behind ‘block skin’ interacts with Allan Block facing units. Refer to figure 3 for how to remove wings.

05 Subsequent Courses Brush the top of the blocks to remove excess material (it is recommended this is done before allowing concrete to set). Place the next course of blocks and level side to side and front to back. Repeat steps 3 & 4 until wall is at finished height.

06 Capping If capping is required, it is suggested that the caps are secured with a cement based flexible adhesive.

Other Reinforcement Options Masonry Reinforcement Allan Block retaining walls can be reinforced with the same proven techniques used for conventional masonry walls. Allan Block masonry walls are useful on sites where geogrids are not feasible or cost effective because they rely on a reinforced footing and vertical pilasters to counteract lateral earth pressures. These walls combine the mortarless stability of an Allan Block wall with the tensile strength of the steel rods in pilasters, and the stability of the footing. The design and construction of these walls follow the guidelines outlined in current AS4678 and CMAA MA52. The specific design requirements depend on site and soil conditions, and wall heights.
