Rock Bolts and Rock Post-tension Anchors

When you have a situation with unstable ground or rocks, then it is necessary to consult a team of professional geotechnical engineers when you want to build or reinforce an existing structure. When excavating, it is crucial to protect workers and the site by securing the walls during the project. In mining, keeping the walls and ceiling from caving in takes precise calculations and robust rock anchoring tools. 

Building dams requires precise securing techniques, tools, and oversight. Our team has the knowledge to advise construction teams on the best placement, application, and use of rock bolts and post-tension systems to provide the best solution for our clients. We tailor our services to meet the needs and scope of your construction project or retrofitting job.

Advantages of Using Rock Bolts and Post-tension Anchor Systems
  • Improves stability for various wall heights and depths
  • Spreads ceiling loads across the surface minimizing the impact on one specific point
  • Versatile option for dam building
  • Upgrades existing structures to code
  • Correct design flaws or hidden problems
  • Can go in place during or after construction
  • Stabilizes shaky ground and foundations
  • Configurable for temporary or permanent applications
  • Holds dams and connecting systems steady and keeps them from washing away
  • Raise or lower existing structures
  • Add stability after deterioration begins
Understanding What Rock Bolts and Anchors Do

Rock bolts are useful tools for excavations and construction jobs around the world. While many countries have different applications for these items, the main principle remains the same. The goal of a rock bolt is to provide support for digging, mining, or tunneling by placing the anchor into a hole workers drill into the surface of the rock or cement. The bolts can go into the roof of underground mines or the walls of tunnels to prevent caving. 

Rock anchors or tiebacks are temporary or permanent structural items, and they often go in place just under the soil. They attach to taller structures to add support during wind loads. They stabilize the building, tension wires, or supports. Geotechnical engineering and construction teams place rock anchors and bolts in one of three manners. 

Ways to Attach Rock Bolts

Each state has regulations, permit requirements, and recommendations for the civil and private use of rock bolts and post-tension anchoring systems. There are three general ways these fasteners go in the ground. We briefly look at each below.
  • Friction - This method is one of the newest applications in the engineering field. To make friction hold the bolts and anchors in the rock requires a specific bolt diameter and length. The size of bolt puts pressure against the borehole walls keeping the anchor and bolt in place. 
  • Mechanical - This technique of rock bolting uses a wedge or conical shape shell to push against the borehole walls. The bolt screws into the cone and causes the shell to open up and push against the soil or cement. Anchor plates and tension cables and rods can further add strength and distribute the weight of the load across the entire anchor area and the rock face instead of solely on the bolt. 
  • Grouting - In grouting, crews place a thick, steel rod with threads into a borehole and put cement or polyester resin grout in place. The tension wires that go in place also get a grout application where they attach at or just below the surface. This form of grouting is a two-step process to add more stability to the anchors. It also prevents rusting by covering the metal parts eliminating the chance of water getting into the connection. 
Some systems like using expanding anchors in the mechanical application offer two types of stabilizing benefits. These rock anchors use friction and a configuration that lock the anchors and bolts into a central system. The combination of applications provides dual support and a long-term solution for dams, tunnels, mines, excavations, foundation work, and other subsurface projects.

Selecting the right size, location, and securing method for rock bolts and anchors requires technical expertise and experience working with these systems. A long-standing knowledge of ground systems and in-depth engineering is necessary for meeting government or local regulations. Staying true to building code requirements and protecting workers during excavation, mining, or construction is paramount.


Our experience covers small and large projects. We work with enterprises, private owners, the government, and small businesses letting us offer you a versatile range of services. We adapt our teams to your project size, timeline, requirements, and budget helping you stay on track and meet company deadlines.
