Compaction grouting is one method of remediating foundation issues by stabilizing loose soils and filling voids in the substrate. These voids and lose soils can cause foundation settling and cracks, and in extreme situations, complete collapse of the soil and structure above. The compaction grouting process begins with the insertion of hollow steel casing into the ground and pumping grout through the casing, filling the voids below. Tools and equipment needed for this process can include the casing, a drill rig for drilling the casing into the ground, and an extractor tool that will pull the casing out of the ground when the grouting process is complete.
Our drill casing is designed specifically for the compaction grouting contractor. Standard sizes are 2.875" and 3.5".
Our drill starter bits are made from high tensile strength drill casing with four or six carbide-tipped teeth. This drill starter bit will penetrate rebar, concrete & asphalt with ease.
Our standard bowls and wedges are made from the highest quality 4140 annealed-hardened steel. The wedges are further flame-hardened at the teeth for added durability.
Built to withstand the rigors of daily use, TMG's casing quick puller removes drill pipe quicker and more efficiently, making pulling pipe safer, easier and faster.
Our new heavy duty wet swivel is designed for high load drilling. This heavy duty wet swivel has a built-in spring loaded automatic float system. This allows for both automatic lifting during unthreading, and shock absorption during threading.
Our standard wet swivel assembly has a built-in casing adaptor and is made from 4340 pre-hardened, aircraft grade steel. Sealed with brass-backed, V-packing preventing the seal from extruding into the bearing at high pressures.
Our standard in-line pressure gauge has a one piece frame with built-in rubber diaphragm that is easily replaceable. Steel U-frame handle provides protection for the gauge, as well as easy grab access.
Our standard recirculation mud tub used for wet drilling is made from lightweight, durable 6061 aluminum. Mud tubs can be made to meet custom configurations and sizes.
Pulling casing from the ground has never been easier. TMG’s casing extraction tool has two 3.5”, 24” stroke cylinders and an optional portable dolly. It is used with a set of bowl and wedges or TMG’s exclusive Quick Puller.
These multi-use hydraulic power units are workhorses, used for both underpinning and compaction grouting. The unique dual-hydraulic connectors allow for simultaneous attachment of extractor tools and connections. Compact, versatile and powerful!
Our heavy duty pipe cart make transporting pipe around the job site easy and convenient. This cart readily stands up to the rigors found on any site. The all turf tires facilitate easy rolling to and from truck to job location. Carry pipe, tooling and small equipment quickly and easily.
Keeping the jobsite clean is a must. The washout T is used when flushing out drill casing, allowing the overflow to be collected in a collection tank.
Our grout to casing connectors are made of high tensile strength steel. Thread patterns or clamps are customized to the customer's needs and can be ordered with single or double start threads, clamp to clamp or clamp to thread. Standard sizes are 2.875" and 3.5" and are available straight or angled.
Our grout casing plug comes with handles and it is used to protect the casing threads and prevent grout or mud back-up. Handles are standard for easy twist on and off. Cap off the grout casing in-between drilling and grouting.
