How To Build A Secura Grand Retaining Wall With Concrete Backfill - Step by Step Installation

mark out the location of the wall by checking the design drawings or by agreement with the project engineer architect or client excavate the trench for the foundation install the foundation material and fill a compact with a plate compactor the typical depth of the foundation should be 200 millimetres after compaction to ensure a level based course remove the nib from the base of the blocks to be used on the base course using a bolster and a Club hammer place the blocks onto the foundation and use a string line along the back of the blocks to check for alignment fill the gap in front of the base course with on-site soil until a compact level with base course lay a perforated drainage pipe at the outer edge of the concrete backfill area the pipe should connect to a suitable outlet or soak away the pipe should be wrapped in the geotextile to prevent clogging our geotextile permeability installed against the root Ian grind ensure the base course blocks are completely level and then fully fill the block Floyds with concrete poker or tamp to ensure the voids are Philly filled fully compact the soil in front of the base course use a spirit level to ensure the blocks are level as you build each course before the concrete has set brush the top of the blocks to ensure there's no excess material push the blocks forward until the nib on the base of the block tightly locates against the course beneath phase the blocks on top of the base course ensuring that they are in a running bond pattern in relation to the blocks on the base course vertical joints should not directly line up between courses it is important that no more than four courses are constructed on backfilled at a time continue to fill the voids with concrete hooker or top to ensure the voids are fulfilled the finish level each pore must be a minimum of 75 millimeters below the top block to facilitate the nib on the rear of the next course install the concrete backhoe before the concrete has set brushed the top of the blocks to ensure there's no excess material Russian should be carried out on each course each left of concrete must be cured overnight prior to installation of further courses on subsequent backfilling repeat the block lane void filling and back filling process until the full height of the wall has been achieved he is 10 millimeter Jinny Jagger gate at the top of the wall according to the design top off the area behind the wall with soil to install a secured copings use a concrete exterior grid construction adhesive applied with a cartridge gun generously apply the adhesive to the block [Music] for film installation details and material specifications please download our secure a technical guide [Music] you [Music]
