ROCK BOLTING SERVICES
We can provide any size, orientation, or lining of the rock bolt required.
What Is a Rock Bolt?
A rock bolt is a steel bar that we install in a structure to stabilize rock and ground. We drill a hole and put in the rock bolt, which can be anywhere from 4 feet to 20 feet long, and threaded in some cases. To keep everything intact, we use grout, a flowable cement mixture that’s used as a bonding agent between the recently installed rock bolt and the surrounding ground.

THE STEPS
Rock Bolting Process
First, we mark out the inside of the tunnel, determining where each rock bolt should go on the plans. Then, we drill a hole and install a steel bar anywhere from 4 feet to 20 feet long, install the rock bolt in the grout, and test the rock bolt.
Depending on the application, if it’s cement that is used, it’s a quicker installation. If resin is used, we install the rock bolt in resin cartridges (a quick-setting bonding agent). Then, we test the bolts to the design specifications.
Wondering if the design bolt is adequate for support for your type and length of bolt? LRL Construction is happy to take a look for you. Ultimately, this depends on the rock quality, which we will assess before drilling into the structure.

WHAT WE OFFER
Types of Rock Bolts
Tensioned Rock Bolts
The only scenario in which this type of rock bolt should be utilized is if another force is necessary to balance out whatever is affecting the structure’s sturdiness. Generally, static rock bolts are the preferred solution.
Static Rock Bolts
The logic behind a static bolt is that if the structure is safe enough to drill into and install rock bolts, it already has an inherent factor of safety. If the structure’s stability is adversely affected in the future, the static bolt will automatically go into tension with the exact amount of force and in the exact location that it should.
