Replace Those Old Railroad Ties

Eric wants to know how one might put a wall system like this together. Brad walks us through the process. 1st Brad wants to make sure they have a good, solid foundation. That's the most important thing. Once the foundation is established, they compact the dirt with a jumping jack or walk behind roller. They then put in about 6 inches of crush and run, then the geo grid netting that the blocks lay on. The netting comes back into the earth approximately 100 percent of the ultimate wall height, as a rule of thumb. There is a 4 inch pipe that runs parallel to the bottom of the wall and they connect that to a water outlet in the bottom of the wall approximately every 30 feet. After the grid is in they then stack approximately 3 more courses of block. They fill the inside of the block with 57 stone and fill 1 foot behind the block with 57 stone. As they're building up they continually test the surface with a probe rod to make sure they have about 95% or better compaction. When it rains or even just normal water perking through the soil can create a lot of pressure behind the walls. The stone behind the walls and in the blocks allows the water to flow through, not pool behind the wall. There is no mortar or anything non permeable, the blocks just stack on each other allowing water to flow through. What doesn't make it out the wall will go to the bottom and eventually out the pipe. That's what's great about this system, it allows water to filter and flow through, it can't be held behind the wall. And, importantly the wall is attractive.

While out this season planting bulbs such as tulips, daffodils and other spring-bloomers, put some aside and pot up a container or two. Gardeners who regularly pot up amaryllis or paperwhites for the holidays often don’t think to grow spring bulbs in pots that will bloom outdoors long after the indoor flowers are just a memory. It’s as quick and easy as potting up annuals. Read more...
