Project Description:

The Tiger Patch liner is a no-dig repair method for localised defects in pipelines. It is suitable for most repairs of cracked, broken or dislocated storm water and sewer pipelines.

Repair is undertaken following CCTV survey to determine the suitability and preparatory requirements of the host pipe (e.g. cleaning needed, tree roots, sharp edges that need to be removed) and to determine the precise position for placement of the patch over the identified defect.

Installation

After CCTV inspection and preparatory work is complete, a fibre reinforced plastic (FRP) patch is wound around an inflatable rubber sleeve. Using a winch mounted on one of Abergeldie Watertech’s specialised vehicles, the patching sleeve is moved into the repair position. Positioning is monitored by CCTV for accuracy. Once in position, the sleeve is inflated with low pressure and held in place until curing of the patch is complete. The result is a patch that adheres tightly to the damaged point, enabling it to be both reinforced and effectively sealed. The Tiger Patch repair system can be undertaken during live conditions at times when flows are low.

Sizes and Materials

Tiger Patch can be used on pipes from 100mm to 1,000mm in diameter. The system is designed for spot repairs 400mm to 1200mm long (per patch) and patches can be overlapped to achieve longer repairs.

The materials used for the Tiger Patch are primarily, hardening and accelerating agents applied to glass fibre, all of which have been developed specifically for this purpose.

Project Description:

Suitable for circular non-pressure pipes suffering from deformations, crack, water infiltration and root intrusion, the Quick Lock system restores leaking or cracked pipes to original condition using a localised mechanical pipe repair technique.

Installation

The Quick Lock patch, comprising a stainless steel ring with a rubber gasket, is coiled around an inflatable packer on an installation trolley. Under CCTV monitoring for accuracy, the packer is winched to the repair location, where the packer is inflated, expanding the Quick Lock patch until it is pressed tightly against the existing pipe. The packer is then deflated and pulled back on the trolley. CCTV inspection confirms the repair is effective.

Sizes and Materials

The Quick Lock patch is available in diameters ranging from150mm to 700mm and is made from a high grade stainless sleeve with an external EDPM rubber sealing gasket.

Project Description:

Abergeldie Watertech offers the AMEX10 seal as a leading system for economical repair of man-entry-sized pipes where pipe joints have failed or for circumferential cracks. It comprises a circular, flexible rubber seal with patented sealing lips, held in place with stainless steel retaining bands.

The AMEX10 seal works by positioning a rubber seal over the affected joint area. Steel retaining bands are then placed into the locating grooves on the surface of the seal. A hydraulic device expands the bands and applies a radial load, which pushes the patented-designed seal firmly against the inside diameter of the pipe.

AMEX10 seals can be installed in most types of man-entry-sized pipes, including steel, cast iron, ductile iron and reinforced concrete. Installation for end seals in pipes from 300mm to 900mm is possible, as well as for man-entry sizes from 900mm to 6000mm in diameter. The seals are flexible and can withstand pipe movement resulting from thermal expansions, contractions, vibrations and ground shifts. The seals can handle operating pressure in excess of 2MPa and head pressure in excess of 30M.

Project Description:

Abergeldie Watertech’s Intruder is a low speed, high torque impact cutter designed for more severe pipe blockages. Pipes blocked by tuberculation, mineral deposits or concrete often require replacement, however the Intruder Hydro-Torque cutter provides a more cost effective, less disruptive alternative.

Abergeldie Watertech’s Intruder machine is the most capable on the market due to its patented ‘Hydro-Torque’ impact drill motor. The machine is powered from a standard jetter. The cutter’s impact drill motor runs at low speed, but provides high torque. The constant water pressure ensures the drilling head does not stop when it meets obstacles. Low pressure vents direct spent water out the front, lubricating and cooling the cutting wheels, and out the sides and rear, removing debris. Typical working specifications are impacts of approximately 1000 blows per minute at 200 rpm. This action is completely water powered which enables the drilling head to keep moving forward when it comes into contact with obstacles.

For pipes obstructed by hardened concrete, stubborn chemical or mineral deposits or protruding taps or root growth, the Intruder is the most effective alternative.
