Proven Technology In Capable Hands


With decades of expertise, there's not much we haven't seen or solved. AFFHOLDER has successfully completed projects ranging from 4-foot diameter to 32-foot arch-shaped tunnels in all types of ground conditions, including soft-ground, soft-rock, hard-rock, and hand-mined.


Minimal Disruption, Maximum Results


Our innovative shotcrete solutions - the application of concrete through a hose under high pressure - provides a versatile tool for strengthening structures in tunnel construction, pipeline rehabilitation, soil stabilization, and culvert repair.


Consistently A Solid Solution

Fast, efficient, and cost-effective, sliplining involves inserting a new, smaller diameter pipe inside the existing failing pipe. Effectively creating a new pipeline within the old one, this technology is perfect for fixing damaged or corroded larger pipes without having to dig up the entire line.

Shaft Excavation
