TTT Bridges

Our bridges are suitable for a range of applications – from residential bridges to highways with a clear span of up to 20 metres.
How it’s done

TTT Bridges combine TTT MultiPole SED piles with MultiPole UniLog beams for strength, durability, and easily installation.

A typical residential bridge includes piles at each abutment. We’ll install these using high frequency vibration, a method that causes minimal disruption to surrounding properties.

We’ll then scallop the pile tops on-site to fit TTT UniLog beams. To finish, we’ll screw timber decking on top.

Benefits of this system

•  Typical construction time of 5 days.

•  Highway bridges can have a 20m clear span.

•  Piles can reach great depths.

•  Non-damaging, non-disturbing installation.

•  Uses award-winning TTT MultiPoles.

•  PS1, PS3 and PS4 provided.

Additional design options

Kicker rails and hand rails can be added as required.

If it’s a ramp or driveway that you’d like to build, our Suspended Floor Foundations might be a more suitable option.

Geotechnical report

Site-specific design

Site visit and installation

First of all, we’ll need a geotechnical report for your site. If you don’t have one of these, we’ll help you get one.

This will be based on your geotechnical report, and could involve the customisation of one or more of our existing foundation systems.

Our installation processes are fast and efficient. They’ll have minimal impact on neighbouring properties and will leave your site undamaged.
