Many foundation problems occur in small, hard to reach areas, which can limit the type of equipment necessary to repair the structural deficiency. At Saribalis Construction, we use tight access drilling equipment that can fit through entryways as small as 3ft wide by 7 ft. high. If we determine that a problem exists in a unique area of a home, we can customize our equipment to access that area without causing any additional damage.
Our portable drilling equipment can drill pier holes up to 50ft deep and 3ft wide. Once the hole is bored we place the necessary pier materials and concrete specified by the engineer. The most common uses for our portable drilling expertise include; decks, foundations and home additions.

Our tieback drilling equipment is track mounted and can drill holes for retaining walls at angles of 15 to 25 degrees, depths of 50ft and widths of 1 inch to 8 inches. We then place the rock bolts with centralizing couplers to ensure the grout surrounds the rock bolt and fills any fractured rock inside the hole.

Using a hydraulic press, we install steel resistant piers down to bedrock depths or until the pipe pile reaches the pier-encountered firm-bearing stratum that is suitable to support the load.
For large retaining walls that require a large amount of rock bolts, we use an Air-Track drifter drill that can bore consecutive holes quickly and at substantial depths.
We specialize in a method of concrete pumping for retaining walls using compressed air to project the concrete directly onto the retaining wall.
