Shoring Up an Under House Earth Bank – Installing a Basic Retaining Wall
Recent rain made it obvious we needed to shore up a bank of earth beneath the house and install a retaining wall. Water runs through soil and will gather under a house, shifting the earth, which then places pressure against walls that will then begin to move
your house with the slope and run of water and create permanently damp walls.
For this DIY Project you will need:Pittwater has a hill and valley landscape and many homes will find they need to prevent this occurring at some stage by removing the soil and build a retaining wall beneath your home, in the cavities between floor and foundation walls.
Work lights; Spade/shovel; Wheelbarrow; Spud Bar (to loosen compacted clay soil); Cement; 2 x 2.4 long 100x200 Treated Pine posts (cut to length to suit on site); Treated Pine Sleepers – standard size – measure to height to determine how many you will need + 1-2 feet above earth level (you can also build a retaining wall in bricks in Besser or Cinder bricks but this will cost more and take longer).; Bolts to secure Posts to Sleepers.
Left: Mirabella LED Tripod Work Light: $119.00 each - • 2 x 20W globes. • Total 2700 Lumens output. • 240V. • 10Amp. • Adjustable tripod.
Steps:Right: Cyclone Hardcore Post Hole Shovel: $67.00
1. Measure the area and height and width of the area that needs to be protected. Ensure you go the fill length of any wall and the height should allow at least 1-2 feet for further soil shifts against the back of the wall.
2. You need to measure where posts (uprights) will be so they sit at approx 1500 apart.
3. Dig out the earth where it is resting against brickwork or walls. You can leave it beneath the house but if you have a spot in the garden where you want to build a new garden bed, extract the dug soil and place it aside to mix with compost ready for late Winter plantings.
4. Dig holes to a least 800mm for Posts. Mix Cement and place post in prior to concreting around it. Ensure it is straight using a Level or String line. Allow cement to cure for at least 8 hours or use quick-set concrete.
5. Install Sleepers behind posts and ensure they are fitted tightly together.
6. Make your Earth Retaining Wall last longer by bolting the posts to the Sleepers at 200mm.
