Trench excavation services for your project

The project cross-section, ground conditions and access determine the equipment. Our main service is disc trench excavation in asphalt and concrete.

Describe my project

TRENCH OPENING / 01

Disc trenching

Widths of 6 or 10 cm and depths of up to 60 cm. For asphalt and concrete, subject to the conditions along each section.

TRENCH OPENING / 02

Chain trenching

This service offers trenches 20 cm wide and up to 1 m deep. This is an option for routes in soil, subject to ground conditions.

TRENCH OPENING / 03

Microtrenching

This service offers trenches up to 3 cm wide and up to 20 cm deep. The trench must accommodate the ducts, their protection and the required cover.

Compare dimensions before selecting equipment

Compare dimensions before selecting equipment
Equipment	Width	Maximum depth	Application to assess
Disc	6 or 10 cm	60 cm	Asphalt, concrete and, depending on the project, soil
Chain	20 cm	1 m	Soil
Compact	Up to 3 cm	20 cm	Compatible small duct installation

Tell us the required dimensions even if they differ from the options above. If they are not yet known, add the drawings or describe the installation. A small trench cross-section is not suitable for every utility project.

What access does the equipment need?

Give the clear width at the narrowest point along the access and working route at each site. The operating guideline for assessing disc equipment is a width of 2.00 m or more; manoeuvring space must also be reviewed.

From 1.50 m up to, but not including, 2.00 m, compact chain equipment in compatible soil or a microtrencher may be assessed, provided the project cross-section and surface suit the equipment. Narrower access does not automatically allow a 6 or 10 cm disc trench to be replaced with a 20 or 3 cm trench.

If the width is less than 1.50 m or is unknown, you can still submit an enquiry for assessment and attach access photographs or a drawing. These clearances are indicative; feasibility must be confirmed against site access and manoeuvring requirements.

Excavation for different installations

We work with construction contractors, fibre optic, electrical and irrigation installers, public authorities, farms and farmers. We assess the excavation; additional works are specified separately.
