Common Manhole & Sewer Problems
HK's manhole lining contractors are skilled at mitigating a wide variety of common manhole problems and restoring flow channels in aging sewer structures. Through 3D manhole inspection technology able to detect structural deficiencies as small as 1mm in size, we're able to pinpoint the problem area to offer precise repair solutions. Municipal and industrial customers often contact HK Solutions Group for assistance with one or more of the following manhole structure problems:
- Manhole leaking
- Cracked manholes
- Groundwater infiltration in sewers
- Manhole failure
- Failing sewer structures
- H2S (Hydrogen Sulfide) concrete corrosion
- And more
Our technicians use a variety of trenchless techniques to restore and reinforce manhole structures, as well as prevent future manhole problems from impacting the sewer system down the road. Mitigation and prevention are especially important for sewer systems suffering from inflow and infiltration (I&I) issues.
Inflow & Infiltration (I&I)
Inflow and infiltration refers to excess water that flows into sewer pipes from groundwater and stormwater. Groundwater typically seeps into sewer pipes and manhole structures with cracks, holes, faulty connections or other structural issues. Stormwater flows into manholes through holes in manhole covers, roof drain downspouts, foundation drains and drain cross-connections. Inflow and infiltration in sewer systems and manhole structures can typically be resolved with structural manhole rehab.
HK Solutions Group offers a variety of inflow and infiltration solutions such as our Monoform™ and Monoform PLUS™ processes. Monoform PLUS™ is especially useful in areas where hydrogen sulfide corrosion exacerbates the concrete deterioration process.
Hydrogen Sulfide (H2S) Challenges
In certain geographic areas, high concentration of hydrogen sulfide in the groundwater can cause rapid concrete deterioration and manhole failure. HK Solutions Group offers H2S corrosion protection with our Monoform PLUS™ manhole rehab solution. Monoform PLUS™ leverages the corrosion-resistant power of HDPE plastic to reinforce and seal leaking manholes. Monoform PLUS™ is a long-term manhole lining solution to combat H2S corrosion and prevent manhole infiltration.
Sulfuric Acid Corrosion
Just as city sewers face maintenance challenges in areas where acidic groundwater corrodes sewer infrastructure, industrial facilities face similar issues. Many factories and facilities handling caustic chemicals have process-water discharge systems with high sulfuric acid content that corrodes subsurface infrastructure over time, leading to infiltration, inflow and other issues. Learn how HK's manhole rehab solutions helped one industrial facility rehabilitate corroded concrete manholes without causing disruptions to business.
Sewer Rehabilitation & Repair of Other Structures
We can do so much more than just manhole lining and rehabilitation. In addition to our focus on Monoform+™, Monoform HEX™ and other manhole rehabilitation techniques, HK is a trusted pipe inspection company, offering CCTV sewer inspections and pipe rehabilitation services, including cured in place pipe (CIPP) lining and UV-cured pipe lining.
