Allied pioneered and developed the concept of underground piercing tools over 37 years ago , establishing a more efficient way to install undergound service utilities. Allied Hole-Hog® underground piercing tools are the most efficient, least expensive method for underground pipe and service placement in construction and installation work.
Hole-Hogs open clean, compacted tunnels for pipe, cable, conduit or wiring at the lowest cost per foot, while the larger model 4000 is utilized in pushing steel casing under roads and railroads. Through continuous process of engineering refinements, Allied provides the construction industry with American-made, premium quality tools that simply do the job better.
