Unlimited Drilling

Founded in 1993, Unlimited Drilling & Foundations Inc. specializes in erosion control in San Diego. This includes a variety of services ranging from grading, landscape retention, foundation repair, slope stabilization and drainage systems.

What is Erosion Control?

Erosion control helps prevent the degradation of natural terrain found within agricultural areas, coastal regions, and/or construction areas. When done well, effective erosion control implements techniques that prevent the negative byproducts of human development such as water and soil pollution, wildlife endangerment, and overall property loss or damage.

Erosion Control Best Practices

There are several best practices which should be followed when managing erosion. As a general rule, during construction, proper oversight is required until permanent site ground covers are in place. Physical, chemical, and all structural and managerial efforts should work to prevent and prevent damage to soil and water. Simply put, erosion prevention best management practices are the best way to retain the structural integrity of surrounding country, wildlife, and developments.

Typically this process includes the following:

  • Assessing if a construction area will require temporary or permanent stabilization 

  • Determining if current vegetation provides necessary stabilization

  • Walking perimeter areas to determine if any other structures will be  destabilized 

  • Pinpointing sediment basins

  • Checking if  slopes have been adequately stabilized

  • Cross-checking operational storm sewers have adequate inlet protection 

  • Ensuring soil doesn’t obstruct public roadway

Unlimited Drilling & Foundations Inc. focuses on several specific services which include:

Foundation Repair.  Foundations with either inadequately compacted clay, poor drainage, or overall weak construction typically make up the primary need for foundation repair. However, in many cases, an inspection is necessary in order to determine the full extent of the damage or repair needs. Unlimited Drilling & Foundations Inc.’s  trained professionals conduct in depth foundation inspections to help determine the full scope of repair needs.

Common Signs of Foundation Issues

Typically, it’s very difficult to catch foundation problems early. Most of the time, foundational issues aren’t apparent until they become a BIG problem. However, there are some things to look for. The most obvious  signs your foundation may need repair if:

  • Windows are difficult to close
  •  Doors that stick
  • Cracks in the drywall/stucco
  • Fissures or cracks in the foundation itself 
  • Sinking or uneven floors 

If you see any of the above signs it may be beneficial to have a  foundation repair expert assess the situation. 

  1. Slope Stabilization/Retaining Walls. One technique for effective erosion control involves the stabilization of soil via the construction of a retaining wall.  The size and type of retaining wall very much depends on the conditions of a property. During the design process, our experts help determine what footing size is needed, if caissions (a watertight retaining structure) should be utilized, as well as if a block wall or poured-in-place concrete. 

While retaining walls come in several variations, some of the most common include: 

  • Gravity
  • Cantilevered
  • Sheet piling
  • Bored pile
  • Anchored
  • Soil nailing
  • Soil-strengthened
  • Mechanical stabilization

Our team will help determine which retaining wall is best suited for your project during the inspection and estimation process.  On a case-by-case basis we also use the following cost-effective approaches: 

Steel beams and pipe-retaining walls on extreme slopes and when building a concrete wall may be too expensive. 

GeoGrid textile fabric to safely rebuild slopes which have failed due to landslide or structural issues. 

Part of slope stabilization also includes drainage systems which we help stabilize with either block walls, wood walls, french drains and/or concrete swales. 

  • Drilling & Caissons. Have a location that’s tricky to access? No problem! We specialize in drilling in all types of sites, including those which may be located on steep or hilly gradients. 

We offer the following caisson drilling capabilities: 

  • Limited access.  This only requires  36 inches of access and is  capable of drilling 36-inch diameter holes to 50 feet in depth.
  • Mini caisson drilling rig. Requiring only 24 inches of  access, this drill-type is capable of  18-inch diameter holes to 50 feet in depth.
  • Tripod drilling. This is an incredibly versatile and portable drilling method which is capable of 6-inch diameter holes up to 50 feet in depth.
  • Mini crawler crane-mounted drill. For this method, only 36 inches of required access is necessary in order to drill 24-inch diameter holes within a 25-foot reach.
