Building a retaining wall using Remastone Blocks is similar to building a standard wall, but it requires some additional considerations to ensure that the wall can withstand the pressure of the soil behind it. Here are the steps:
Choose the location where you want to build the retaining wall. Clear the area of any debris or obstacles that could interfere with the wall's construction.
Measure the length and height of the wall you want to build. Calculate the number of Remastone Blocks and amount of mortar mix you will need for the project.
Lay a string line along the length of the wall to ensure that the wall is straight.
Use a shovel to dig a trench along the string line that is deep enough to accommodate the first layer of blocks and mortar. The trench should be wider than the blocks to allow for drainage and backfill.
Lay a geotextile fabric along the bottom of the trench. This will help prevent soil and water from eroding the wall's foundation.
Add a layer of crushed rock to the bottom of the trench to provide drainage. The drainage pipe should be placed at the base of the trench and covered with more crushed rock.
Lay the first layer of blocks on the mortar bed. Use a spirit level to ensure that each block is level. The gap between the blocks should be around 20mm.
Apply mortar to the top of the first layer of blocks and then lay the second layer of blocks. Make sure that the blocks are staggered so that the seams are not in line with each other.
Repeat the process until you have built the wall to the desired height.
Backfill the area behind the wall with crushed rock to promote drainage and prevent soil erosion.
Finish by filling the remaining space behind the wall with soil and compacting it with a plate compactor.
Once you have completed the wall, allow the mortar to dry for at least 24 hours before applying any additional weight or pressure.
Remember to always wear safety glasses when working with Remastone Blocks and mortar mix to protect your eyes. Additionally, be sure to consult with a professional if you have any doubts about the structural integrity of the wall or if you need to build a wall taller than 1 metre.
