If you are looking to buy a new home, one of the things you want to check is that the property is protected from a rock fall. This could be rocks and dirt falling into your yard or onto your home from a nearby hill, or it could be the built-up slope under a portion of your foundation falling. Here are a few things to look for.
Steel Mesh Netting
When the foundation of the home was built on a slope, you need to be sure that the ground underneath is not going to slip and cause it to crack. One method of securing the ground is with steel mesh netting. The mesh is pulled around the dirt mound and secured to pylons deep in the ground. This allows the rocks and dirt to shift within the netting but they will not fall away from under the foundation. Additional dirt can be placed over the netting so grass or other landscaping can be done.
A rock drape is used when you have a rock hill or steep slope in or near the yard. It is steel mesh, but in one big drape that is secured at the top and bottom of the slope. Any rocks that become loose and fall will stay within the mesh at the bottom, keeping them form gaining momentum and crashing into the house.
Another option for a rock slope near the building is to have a shotcrete facing poured over the slope. This will cover the entire slope and cement the rocks in place. It can be used in conjunction with a rock drape for added security. I can also be used on the slope under the foundation, but the area should not be planted as the roots can break through the shotcrete.
A pile wall consists of steel piles driven into the ground in front of the slope. Wood or concrete panels are then placed behind the piles (against the slope) to keep the rocks in place. While not the most aesthetically pleasing solution, it will hold the slope material from falling into the yard or buildings.
Whether the slope is under the house or next to the yard or property, you need to be sure there is not going to be any landslides that will cause damage to anything. To learn more about your options, contact companies like Geotech Solutions Inc.Share
