Services
Elevator Pit Leak Repair
Specialized leak mitigation for commercial and industrial elevator pits through foundation excavation, French drain systems, and chemical injection grouting. Our technicians address cold joint leaks, shaft seal failures, and underground water ingress using flexible water-activated materials. We implement durable solutions combining excavation, drainage, and structural reinforcement to exceed industry standards for subterranean waterproofing.
Concrete Waterproofing
Comprehensive waterproofing solutions for existing structures using spray-applied coatings, sheet liners, and epoxy crack repairs. We diagnose root causes of water intrusion before applying protective systems from manufacturers like Sealboss and DeNeef. Our approach ensures long-term protection for wastewater tanks, manholes, and underground facilities while maintaining structural integrity.
Seawall Restoration
Structural remediation for coastal and riverfront properties through crack injection, surface coatings, and joint sealing. We utilize marine-grade materials to address bulkhead deterioration from saltwater exposure. Our repairs extend service life for waterfront structures while maintaining regulatory compliance with environmental protection standards.
Crack Repair
Precision crack mitigation through high-pressure resin injection and expansion joint replacement. Our technicians identify crack origins before applying flexible sealants that accommodate structural movement. This prevents recurring water infiltration in parking structures, foundations, and retaining walls using polymer-modified systems.
Pipeline Rehabilitation
Infrastructure restoration for stormwater and wastewater systems including manhole renewal, pipeline relining, and tank repairs. We implement cured-in-place pipe (CIPP) technology and structural liners for aging underground networks. Our solutions maintain municipal service continuity while meeting current capacity requirements for public works systems.
