Amex Internal Pressure Seals

H&B are able to provide the full catalogue of Amex Sanivar’s pipe seals known as the “Amex Seals”. There are many different applications of the seals that can be used to repair broken or cracked pipes or displaced joints meaning the requirement for full pipeline replacement could be eliminated. There are options to custom make the seals to suit a specific pipe diameter or profile which can be designed and fabricated on a case-by-case basis.


How it works?

  • Amex Seals are composed of EPDM rubber providing both flexibility and endurance

  • With a size range from 600mm to 6000mm, there is something for almost every job

  • Depending on the damage, the width of the seal ranges from 180mm to 600mm for the Mono and even greater for the Vario!

  • Tested to withstand internal pressures of up to 25 bar and external pressure up to 8 bar

  • The seals can be installed in any type of pipe material and most shapes

Installation Methodology

  • The seal is first put into place
  • The steel bands are then secured using a hydraulic tool
  • A shim is hit into the space created by the hydraulic tool in the steel band
  • The hydraulic tool is removed and the next steel band is placed

Main advantages

  • Use of hydraulic tool allows for quick and easy installation

  • Design life of over 50 years!

  • More than 30 years of experience between our technicians

  • Own production and service
  • No resin, no impregnation, and no curing needed
  • Can be custom made to fit your specifications

Structural Fibreglass Lining

Hadlee & Brunton specialise in patching existing drainage pipes with a fibreglass repair. This is a cost effective and easy to use solution for the permanent and watertight repair of damaged pipes, without the need for excavation work. We can patch a damaged section of pipe over 40m from where we enter the drain. We can repair most types of pipes including ceramic / clay, concrete, uPVC, metal and much more, from 25mm up to 1200mm in diameter. The Fernco Pipe Doctor is installed internally and eradicates the need for costly, disruptive and time consuming excavation work therefore enabling both vehicle and pedestrian traffic to move freely without realising drainage and sewer work is being carried out underground.


Benefits

The Fernco Pipe Doctor is an innovative format that offers considerable benefits to our clients.
  • A Severely cracked drain
  • Root Intrusion
  • Displaced joints
  • Quick and easy to use no dig application (No disruption)
  • Permanent and watertight pipe repair which can be used for root intrusion issues
  • The drains can remain running during the installation
  • Environmentally and ecologically friendly
  • The only WRc Approved patch repair in the marketplace, also meeting international standards
  • Reduces site wastage
  • The Fernco Pipe Doctor has been tested using the Fernco installation equipment and a guarantee of 10 years has been established for the materials.

Manhole Rehabiltation

100% SOLIDS STRUCTURAL EPOXY COATING SYSTEM

The Ultracoat system is a structural epoxy coating system used for the rehabilitation and structural reinforcement of a wide range of substrates. Manhole repair, tunnel maintenance, bunds, culverts, and any other surface or structure can be coated. After its single coat application, Ultracoat leaves an exceptionally hard wearing, smooth and waterproof coating, with excellent chemical resistance.
Hadlee and Brunton applying Ultracoat to Council Manholes

Even in the presence of damp substrates, Ultracoat will effectively adhere to any surface, eliminating and preventing infiltration and leaving a smooth finish with enhanced flow characteristics. Application of Ultracoat is also structurally reinforcing – independent testing showed an increase in compressive strength of concrete pipes of 20%.

After application, for example for bund rehabilitation, the Ultracoat 100% solids epoxy coating system is chemical resistant from pH 2-14. This includes complete resistance to high levels of hydrogen sulphide, up to 40% concentration of nitric acid, acetic acid, calcium chloride and others.

Particularly relevant for manhole rehabilitation and other confined spaces, the Ultracoat system is free from VOCs (volatile organic compounds), meaning breathing apparatus is not required. It is free from solvents and no primer coat is required – application is quick and easy and a manhole chamber or culvert can be back in operation within hours of the project starting.

The Ultracoat epoxy coating system was developed by Danny Warren of Warren Environmental in the USA over 35 years ago and has been used to renovate over 50,000 manholes and kilometres of pipes and tunnels – WITH ZERO FAILURES.

The Ultracoat system is CE marked and complies with the standard BS EN 1504-2:2004 “Products and systems for protection and repair of concrete structures – part 2 surface protection systems”.

The following are the key
applications for the Ultracoat system:


ULTRACOAT – MANHOLE REPAIRS

The Ultracoat system has been used for the rehabilitation of over 50,000 manholes worldwide, each project avoiding the disruption of replacement, reducing immediate costs and bringing whole life cost for the structure down to a minimum. When presented with a corroded surface, perhaps after long term erosion and widespread infiltration, there are two main alternatives; the replacement of the manhole, or the repair of the manhole.

ULTRACOAT – TUNNELS

The Ultracoat system has been used successfully on tunnel and subway infrastructure for many years. Replacement of a man entry tunnel or a subway structure is rarely an option, and due to being a confined space and the need to maintain a structural strength, options are limited.

ULTRACOAT – CULVERTS

After initial successes with manhole rehabilitation, Ultracoat has more recently been used with great success for culvert surfacing and repair. Below shows a recent success in Tasmania, on a hydroelectric flume. See our Case Study section for more images and additional project details.

ULTRACOAT – LARGE CHAMBERS

Many chambers are by definition confined spaces, and so Ultracoat is the ideal solution when chamber rehabilitation is required. No breathing apparatus is necessary, and so the complexity of a project is kept to a minimum.

ULTRACOAT – BUND LINING

Ultracoat is increasingly used for bund lining and other asset management projects.

TESTING AND ACCREDITATIONS

The ultracoat system has been tested to the following standards
