CONFINED-SPACE MANHOLE REPAIR & RESTORATION
Manholes are critical access points for sewer and storm drain systems—but they’re also vulnerable to infiltration, corrosion and structural degradation. TrenchFree performs manhole rehabilitation to address these issues and extend the service life of your underground infrastructure.
Our confined-space certified crews safely restore manholes using industry-approved methods, ensuring compliance with OSHA regulations and municipal standards.
Common Manhole Problems
Our advanced camera inspection technology detects a wide range of pipeline and manhole defects
Groundwater entering through cracks, joints or deteriorated seals
Hydrogen sulfide (H2S) attack on concrete and metal components
Settlement, traffic loading or age-related deterioration
Surface water entering through damaged frames, covers or chimney seals
Rehabilitation Services
Comprehensive system assessment to ensure efficiency and compliance
Cementitious or epoxy coatings to restore structural integrity
Chemical grouting, sealing and waterproofing
