The Best Horizontal Directional Drilling Equipment for Your Needs

Horizontal Directional Drilling (HDD) is a method of installing underground pipelines, cables, and service conduit through trenchless methods. Numa’s horizontal directional drilling tools are a good fit for installing infrastructure such as telecommunications and power cable conduits, water lines, sewer lines, gas lines, oil lines, product pipelines, and environmental remediation casings. Many of our customers have found great success using HDD products when crossing underneath waterways, roadways, congested areas, and environmentally sensitive areas where other methods are costlier or not possible due to rock.

Numa offers a wide variety of HDD drilling systems consisting of HDD hammers, bits, side load sonde housings, bent subs and adaptors capable of drilling holes 3⅞ – 7½ inches (98 mm to 191 mm) in diameter. Some of the many benefits Numa touts for the HDD product line include: improved steerability, fast penetration rate, simplified field maintenance, reduced air requirements, and lower overall cost per foot.
