Our Services

At Crest Rope Access Ltd safety is our top priority and we ensure every member of our team has had the finest training and a vast amount of experience.  The boss, Paul Johnson has been in the industry for 15 years and is a level 3 supervisor.  Our services are varied and we will always consider any challenge you may be having with any project.

Using our rope access services can give you many benefits:

• Greater flexibility than is possible with any fixed structures or scaffolding.
• Quieter service with the minimum of fuss.
• A greater level of security as not fixed structures are left on site.
• Less congestion at the foot of projects.
• Access to areas it would be impossible to reach normally.

Geotechnical Services

Our Geotechnical services include:

• Geotechnical Work
  • Geotechnical Investigation
  • Anchor Installation
  • Catch Fences
  • De-vegetation
  • Netting and Erosion Control
  • Rock Bolting
  • Rock Scaling
  • Soil Nailing
  • Sprayed Concrete

The key to the best design solution for potentially unstable rock and soil slopes is understanding the likely failure mechanisms and risks.

Crest Rope Access Ltd is able call on qualified geotechnical engineers to access slopes with roped access or mechanised access plant and produce detailed inspection reports with budget costs and prioritised remedial action.

We work closely with Site Investigation contractors to assist in gathering data from slopes and rock faces by visual and intrusive techniques.

Cliff Stabilisation

Loose rocks and unstable cliffs can become a menace together with a massive safety risk.  Stabilisation can come in many forms such as reinforcement, dewatering (drainage of excess rainwater to reduce water-logging) or anchoring (the use of terracing, planting, wiring or concrete supports to hold cliffs in place).

Rock Fall Protection

Rock Fall protection and rockfall mitigation are key works in the safety and security of the public, infrastuctures and people.  The smallest of rockfalls can have far-reaching economic effects beyond the disruption it can initially cause.  We will learn your needs and execute a simple, effective a durable plan to solve the problem.

Rope Access

The core to our business is rope access.  This skilled ability allows us to perform many duties such as window cleaning, abseil cleaning, banner and signage installation, building maintenance, bird detterents, wind turbine inspection and harbour wall surveys.  This list is not exhaustive.

 

Anchor Installation

Anchors are used to restrain and stabilise large masses of rock and to tie back walls and other structures. Anchors may be temporary or permanent and dependent on environment have varying levels of corrosion protection. Detailed testing and stressing of anchors is necessary to meet design load requirements.

Crest Rope Access has extensive experience in monobar and strand anchor installation in a wide range of ground conditions and in difficult locations using our adapted cliff face rigs, including testing and stressing by qualified engineers and production of reports.

Catch Fences

Catch Fences are used to contain rock falls and soil/rock debris flows. Fences generally range in height from 1m to 5m and are constructed from a variety of materials specific to the design and application of the particular installation. Fences are often classed by an energy rating determined by likely rock trajectories and masses.

Crest Rope Access Ltd installs energy rated fence products from Maccaferri and Geobrugg, as well as simple static fences to contain minor rock falls in lower risk situations. We offer a fully designed solution where required.

We also design and install temporary catch fences as part our cliff works to allow works to proceed with continued operation of roads, railways and public/business operations. These methods often result in improved efficiencies and reduced costs while maintaining exemplary safety standards.

De-vegetation

De-vegetation is usually the first of several stages to secure a rock face or soil slope. It is carried out where vegetation needs to be cleared to enable safe inspection work, or where there is a need to remove loose rock or unstable soil.

In some situations the root systems of vegetation themselves can cause instability and their safe removal can often be used as a stand-alone solution.

The skills and experience of Crest Rope Access Ltd enables us to carry out this work in a safe and environmentally sympathetic manner.

Rock Scaling

Rock scaling is used to remove loose surface material presenting a rock fall hazard, usually with prybars and picks. Where large sections of rock or large boulders require controlled removal, a variety of techniques can be utilised including winching, bagging of material and breaking up in situ using power tools.

Temporary catch fences are often used in the scaling and rock removal process. Scaling can be a stand-alone solution but is often undertaken as the initial process in a stabilisation project.

Experienced Rope Access crews working to strict safe working practices are available at short notice for emergency scaling works where immediate action making safe of areas is necessary.

Soil Nailing

Soil nailing enhances the stability of slopes by the installation of grouted tendons in a regular grid pattern. The technique is ideally suited to hollow bar systems where drilling is undertaken with pneumatic or hydraulic drill rigs driving the bar using a sacrificial bit, followed by pumping grout down the centre of the bar. Traditional open hole drilling/casing methods are also used and, in certain conditions, driven deadman type anchors.

A facing system such as mesh, erosion control or structural concrete is often used to tie the nail heads together to allow a vegetated surface to re-establish.

Crest Rope Access Ltd has a wide range of drill rigs suitable for mounting on our cliff rigs and on standard and long reach excavators.

Netting and Erosion Control

Rock netting is used as a containment measure to mitigate rock fall risks. The netting (commonly called mesh) takes the form of a drapery secured at the crest and toe by dowels with additional profiling/support cables as necessary. Netting can be released to allow accumulated rock falls and requires basic inspection and maintenance.

High tensile netting provides active support in conjunction with dowels/bolts on a grid pattern.

Erosion control netting or matting can be used with rock netting or as a standalone solution, to reduce weathering and assist in regrowth of vegetation, sometimes with addition of topsoil and seed mixes.

All types of netting and erosion control are installed by Crest Rope Access in a wide range of locations, from large quarry faces to newbuild housing developments and extensively to road/rail infrastructure.

Crest Rope Access Ltd has developed specific techniques for the safe and cost effective installation of mesh and this work has always been at the core of our business.
