Core Assemblies

Specialized moisture defense

Substrates demand exact chemistry matching site conditions. We engineer and apply cold fluid polyurea, hot-rubberized asphalt, and bentonite composite sheets.

Remedial

Blindside Foundation Tanking

Split-Slab Podium Systems

High-Pressure Polyurethane Grout

HDPE and bentonite composite sheet systems mechanically locked to poured concrete footings to resist active subterranean water tables.

Hot-rubberized asphalt and reinforced elastomeric membranes detailed across expansion joints, pavers, and vehicular wearing surfaces.

Forensic chemical injection sealing fractured cold joints and active structural water weeping without disruptive excavation work.

Engineering Protocol

Monolithic substrate bonds endure.

Water migration exploits microscopic substrate voids. We mechanical-blast concrete to ICRI CSP-3 standards before applying continuous elastomeric barriers with non-destructive electronic vector testing.
