WrapidSeal Controls Infiltration, Prevents Deterioration, Provides Structural Integrity of Manholes
Manholes deteriorate, as a result of soil stresses, groundwater, exposure to sewer gas, structural movement from traffic loading, and soil movement from wet/dry or freeze/thaw cycling. Over time, the deterioration will cause infiltration of groundwater and soil into wastewater or stormwater systems. In paved areas, manhole deterioration can generate sinkholes and cause pavement to fail.
This results in restraints on treatment plant capacities and increased costs for processing groundwater, paving repairs, traffic disruption, and ongoing damage to manhole and surrounding structures.
The newest solution is WrapidSeal Manhole Encapsulation, from CCI Piping Systems, that effectively seals the joints and extends the service life of a manhole.
WrapidSeal Manhole Encapsulation System consists of an engineered primer and a unique, wrap-around, heat-shrinkable thermoplastic sleeve that conforms to the shape of the manhole and forms a tight monolithic seal. Designed specifically to control infiltration and prevent deterioration, WrapidSeal can be used on both new construction and rehabilitation of existing manholes, eliminating costly maintenance and repairs, and added expenses of treating groundwater.
In addition to its high shrink and abrasion resistant features, the system has high tensile strength and elongation to accommodate structural movement and provide long-term protection. It can also be installed in any climate, with minimal surface preparation and limited field training required.
Due to cost considerations, most manhole rehabilitation involves partial replacement – only the top 12 to 24 inches – of the structure. This is where WrapidSeal performs particularly well because of its unique ability to conform, seal, accommodate movement, and provide structural integrity. •

Epiroc, a leading productivity partner for the mining and infrastructure industries, introduced the Pit Viper 291 blasthole drilling rig, which delivers productivity, application flexibility and enhanced operator safety
The single-pass rotary drill is designed to tackle larger-diameter drilling in soft to medium ground conditions. Capable of 11- to 12.25-inch diameter holes with 85,000 pounds bit load capacity, it brings unsurpassed performance to any drilling operation and further extends Epiroc’s industry-leading Pit Viper range.
It also offers 80,000 pounds of pulldown capacity, 35,000 pounds of pulldown force and 11,000 foot-pounds of torque.
With Epiroc’s Rig Control System (RCS), Pit Viper 291 can be configured with scalable automation features, including fully autonomous drilling.
Vermeer

Vermeer expanded horizontal directional drilling (HDD) crews’ tooling options with the new Ultra X3 Drilling System. Designed for utility-sized rigs, with a unique, non-torqued spline connection system, Ultra X3 offers compatibility with a wide range of pilot bit
and pullback configurations. It’s also ultra-versatile, delivering value and efficiency.
Due to its robust spline connection system, tooling doesn’t have to be threaded on, eliminating the need for breakout tongs to make and break torqued tooling connections. Operators just need to align the spline on the tooling with the spline on the housing, then secure tooling by tapping in dowel pins.
The system can handle the torque of reaming diameters up to 10 inches (25 cm) in most conditions from the transmitter housing. Also, it’s set up to use a full offering of plate bits and rock tooling, like the Vermeer Gauntlet, Lance and single roller cone bits.
The Ultra X3 housing uses a standard API rear connection and works with quick-connect systems. However, contractors who seldomly remove their housing may find value in skipping the expense of starter rods and collars, because there is a quick connect on the bit side of the housing.
Using the Ultra X3 system can help reduce the size of the exit pit in some applications, which can also help reduce restoration work.
