Several installation methods

Comrod’s composite masts can be installed with a rock drilling method, buried foundation or steel adapter. Our self-developed method of rock drilling has been very well received by the industry, and is described as revolutionary compared to the traditional installation. In loose ground, a buried composite foundation is used. We have also developed a steel adapter that can be used where the pole is exposed to less force or other conditions allow.

Rock drilling concept

With this method, a slot is drilled into the rock with our in-house developed drill rigs. The computer-controlled rig drills with very high accuracy so that a composite foundation pipe can easily be lowered into the slot. The poles is slid over the foundation and bolted in place. The method allows foundation work close to live line cables and enables installation of the poles to be safer, easier and more efficient.

Low Environmental Footprint

The drill rig is adapted to weight restrictions for helicopters (B3) and flown directly to the site. This avoids nature-damaging construction roads. The rock drilling concept also provides a minimal footprint around the mast position. The poles are flown in and slide directly onto the composite foundation.

Developed for demanding terrain

This method avoids any kind of rock blasting. The drill rigs simplify the work where there is difficult access and steep and demanding terrain. The rock drilling concept also enables live line work. Also A-masts can be installed with this method.

Cost-saving and efficient

Multiple drill rigs enable drilling of several mast points simultaneously. Furthermore, the stability of the foundation allows a reduction in the number of mast positions. We offer training in the use of drilling equipment, so that customers may carry out foundation installation using their own personnel.

Buried foundation

Buried foundation in the traditional way with corrugated plastic pipe in which the post is placed. Opportunity for “short bottom modules”. This makes it possible to complete all the groundwork at the mast point, and provides a finished foundation to slide the mast on – similar to the rock drilling concept.

Steel adapters

In-house developed steel adapter for easy and cost-saving installation of mast positions where there is less load. The masts are placed on the foundation, avoiding the use of stay wires when installing the masts. We develope solutions for customers enabling the installation of our products to be as efficient and HSE-friendly as possible.
