Transport

Harbour subsidence

The fast & non-disruptive solution to seawall, port and harbour subsidence

Substantial traffic and heavy loads put a huge strain on infrastructure at busy port terminals. This can cause significant ground subsidence and damage to concrete foundations. The infrastructure is much more likely to deteriorate under pressure.

If left untreated, harbour subsidence can pose safety risks and interfere with the smooth running of operations.

Mainmark has been providing level correction, ground improvement and void filing solutions to port terminals for more than 30 years.

We understand the importance of working within tight timeframes of scheduled shutdowns or emergency works, working collaboratively and efficiently, with minimal interruption to the terminal operations, while placing safety above all else.

Applications of Mainmark harbour subsidence treatment

Seawalls

Pavements

Buildings & structures

Keeping the UK’s port terminals operating efficiently and safely and treating harbour subsidence with modern technologies

Slab lifting process for port infrastructure affected by harbour subsidence

Small holes are drilled through the slab.

Multi-component strcutural resin is injected. It expands immediately, filling any voids and compacting the substrate.

After re-supporting the slab, continued injection raises it, guided by the laser level.

The treated pavement sections are returned to full operation immediately after the repair work, and no curing time is required.
