Mud Drilling

Mud drilling is not the only way to put a hole in the ground, but it is undoubtedly the most versatile and dependable method. One of the most critical roles of drilling mud is as a lubricant. Drilling generates tremendous friction, which can damage the drill or the formation being drilled. Drilling mud cuts down on the friction, lowering the heat of drilling and reducing the risk of friction-related complications. The mud also acts as a carrier for the materials being drilled, with material becoming suspended in the mud and then being carried up the drill to the surface.

Air Rotary Drilling

Air rotary drilling, the ideal method for advancing boreholes into consolidated bedrock formations, uses a rotary-driven drill bit and high-pressure, high-flow air. Typically, either a "tricone" cutting bit or a downhole percussion hammer is used to penetrate the rock surface and grind the rock into small particles. High-flow air is injected through the drill string, cooling the bit, evacuating rock cuttings from the borehole and stabilizing the borehole during drilling.

Well Drilling

Our facility currently operates with 5 rotary rigs, each one run by a two man crew. We offer drilling for both residential and commercial jobs in most surrounding PA counties. Our services include drilling for domestic, irrigation and public water wells, monitoring wells, test wells, and geothermal boreholes. Please refer to our Geothermal page for more information on our geothermal services. We also offer well repair services if you find your well is not satisfactory. Our men are equipped to come out and install well liners alone or together with a well packer to prevent the well from falling shut or simply to case off a bad stream. Please give us a call for a free estimate.

Well Grouting

Well grouting is the process of filling the space that is left between the well casing and the surrounding earth after drilling. The purpose of this procedure is to prevent contaminates from entering the well. We use either Portland I cement or bentonite to grout the well casing. The product is mixed in our pressure grout machine and then pumped into the space starting at the bottom of the casing until it reaches ground surface. Please note that not every county in Pennsylvania requires pressure grouting.

Well Abandonment

Many times there is an old well on a property that is no longer being used. The state of Pennsylvania requires that any such well be abandoned. In other words, the well must be decommissioned. We offer this service to any home/land owner in need of abandoning an old well. The following link will provide you with a more detailed description of water well abandonment guidelines
