Drilco Inc has experience in all types of caissons from cased piles to slurry method Drilco Inc can do it all. Our wide variety of custom built tooling and accessories give us the ability to take a pile to depth regardless of soils conditions.

Temporary shoring is a form of slope stabilization using soldier piles and plate lagging indoor to achieve the proper elevation of a cut were lay back cannot be utilized due to existing improvements surrounding a construction site. Utilizing temporary plates and beams allows a safe site condition for other trades and allow for a lower cost to our customers.

Permanent shoring is utilized when a wall is needed to be placed directly on a property line or site condition do not allow for a conventional cast in place wall. This process involves the use of soldier pile, timber lagging and sometimes shotcrete. We have the crew and the knowledge to perform all the process need to complete these projects all in house.

There are several types of soil anchors; tiebacks, soil nails, rock bolts and helical anchors. All are generally installed in a horizontal plane. Each type is tension tested to ensure they reach design requirements.

Auger Cast in Place (ACIP) piles are constructed by rotating a hollow stem continuous flight auger into the soil to a designed depth. Concrete or grout is pumped through the hollow stem, maintaining static head pressure, to fill the cylindrical cavity created as the auger is slowly removed. The grout pressure and volume must be carefully controlled to construct a continuous pile without defects.

Drilled displacement piles (DDP) refers to a specialized technology in which a bored pile is constructed using a process in which a specially designed tool is advanced into the ground using both rotation and downward thrust (“crowd force”) to displace the in situ soil radially outward into the surrounding formation.

Jet grouting creates in situ geometries of soilcrete (grouted soil), using a grouting monitor attached to the end of a drill stem. The jet grout monitor is advanced to the maximum treatment depth. Then high velocity jets (cement grout with optional water and air) are initiated from ports in the monitor. The jets erode and mix the in situ soil with grout as the drill stem and monitor are rotated and raised.

Our equipment can be fitted with single auger or cutter wheel to directly inject binder into the mixing zones. The stabilization agent is combined with the soil to be treated and mixed by the mixing blades. These parameters are adopted accordingly as a function of soil strength and specifications to be achieved.
