Domestic Drainage Services for Blocked Drains in Essex & Hertfordshire

We offer a complete drainage service 24hrs a day, 365 days a year. For details on any aspect of our domestic drainage work please click below.

Blocked Toilet and Soil Vent Pipes

A blocked toilet can be caused as a result of a variety of different problems such as foreign objects causing obstructions to the toilet outlet and/or drain pipe i.e. toilet fresheners, toys, sanitary ware or nappies through to a build up of wipes and/or toilet paper which has caught on a broken pipe or scale.

Scale is extremely prevalent in the Essex and Hertfordshire areas due to the hard water and causes numerous problems within the drainage systems. The scale found in drains is not unlike the build up experienced in a domestic kettle, just on a more wide-spread basis.

Whatever the problem and its cause, Drainage & Hygiene Services and Clean Drain will rectify the problem by utilising the most appropriate tool for the job, from manual plungers, rods and electro-mechanical equipment through to high-pressure water jetting units and CCTV camera equipment.

Blocked Sink, Waste Traps and Pipes

A blocked sink is usually caused by a build-up of food waste and grease within the trap, pipe work and/or external drain resulting in the sink draining away very slowly or not at all. A partially blocked sink can also cause unpleasant smells to emit through the plug hole and overflow.

Drainage & Hygiene Services and Clean Drain have a variety of different methods to deal with these problems from plungers and air guns through to electro-mechanical 'worm' machines and high-pressure water jetting to unblock and de-grease the drain.

Blocked Drains

A blocked drain can be caused as a result of various different problems such as scale, grease, root ingress, foreign objects in the drain. Blocked drains can also be caused by a build up of waste paper and wipes on a broken drain.

Drainage & Hygiene Services and Clean Drain will rectify the problem by utilising the most appropriate tool for the job, from plungers, rods, electro-mechanical equipment, high-pressure water jetting and CCTV camera equipment through to excavation and repair or GRP lining.

Blocked Down Pipes, Stack Pipes and Roof Gullies

Drainage & Hygiene Services and Clean Drain offer cleaning services for down pipes, stack pipes, roof gullies and hoppers within the Essex and Hertfordshire areas. Various techniques are used to clear blockages and clean the drains, bagging and removing debris, leaves, rubbish and general detritus from site

Blocked Linear and Channel Drainage

Channel drains also known as Linear or ACO drainage are usually found on driveways and pavement areas in front of store fronts. They work in a similar fashion to Road gullies. They collect and channel surface/storm water to a silt trap prior to connecting onto the surface water drainage system. As with road gullies, the silt trap needs to be emptied and the drain lines cleaned on a regular basis to prevent collected deposits overflowing into the surface/storm water system. Drainage & Hygiene Services and Clean Drain utilise a specialist gully emptying unit which is used to empty the gully and petrol interceptor traps and flush through the drain.

Equipment

Drain Clearing Equipment
Rods

Manual rodding is an extremely efficient and cost effective way to clear drains. It takes moments to set up and is a straight forward, no nonsense way to clear simple blockages. The specialist rods used by our engineers are designed with different attachments which can be used in a variety of different situations dependant on the type of blockage. However, sometimes it is not possible for a persistent blockage to be cleared by this method, in cases such as these, electro-mechanical equipment or high-pressure water jetting equipment is utilised.

Electro-mechanical Equipment

Electro-mechanical equipment is often referred to as a 'mechanical worm' and covers a range of machinery varying in size and application. This type of machinery is most often used to clear blocked sink and waste pipe work and stack pipes within flats and commercial properties. It comprises a flexible steel cable which is attached to the head of the machine. It is inserted into the pipe work and rotates, clearing the pipe work as it works its way through the drain.

High-Pressure Water Jetting and Vacuum Tanker

Drainage & Hygiene Services and Clean Drain have varied sized and powered jetting units, from van packs, which are an integral part of our drainage vehicles through to towable twin-tank units and Lorry mounted units.

High-pressure water jetting is used in various applications, such as clearing blockages and removing deposits of stone, debris or detritus from the drains.

Drainage & Hygiene Services and Clean Drain are trained and assessed by the Water Jetting Association to ensure the company and all our engineers conform to the implications of Health & Safety.

Blocked Linear and Channel Drainage

Channel drains also known as Linear or ACO drainage are usually found on driveways and pavement areas in front of store fronts. They work in a similar fashion to Road gullies. They collect and channel surface/storm water to a silt trap prior to connecting onto the surface water drainage system. As with road gullies, the silt trap needs to be emptied and the drain lines cleaned on a regular basis to prevent collected deposits overflowing into the surface/storm water system. Drainage & Hygiene Services and Clean Drain utilise a specialist gully emptying unit which is used to empty the gully and petrol interceptor traps and flush through the drain.

Soakaway Drains, French Drains and Land Drainage

Soakaway drains, French drains and Land Drainage are primarily used to disperse rain/surface water into the ground, particularly in areas of Essex and Hertfordshire where there is no mains surface water drainage. The drains come in various designs and sizes and are designed and installed in accordance with the Environment Regulations and Building Regulations. The design and position of a soakaway drain, French drain or Land drain is dictated by the Building Regulations, however various factors need to be taken into account to ensure the suitability of the drain to its purpose such as the catchment area, the amount of rain and surface water expected to filter through the drain, the type of surrounding soil i.e. clay, loam etc., the proposed site of the drainage and cost.

Soakaway drains, French drains and Land drains can fail overtime due to stone and earth filtering down into the drains causing clogging to occur.

Drain Scale, Urinal Scale and Descale

Drain Scale is extremely prevalent in the Essex and Hertfordshire areas due to the hard water and causes numerous problems within the drainage systems. The scale found in drains is not unlike the build up experienced in a domestic kettle, just on a more wide-spread basis. Drain Scale commonly causes paper and wipes to catch on its rough surface, causing a build up which eventually blocks the drain.

Specialist descaling equipment is used to strip the scale from the drain and restore the flow characteristics of the drain. Drainage & Hygiene Services and Clean Drain also offer urinal pipe work cleaning, removing deposits of urinal scale, the build up of which can seriously reduce the bore and flow characteristics of pipe work.

Drain Root Removal

Drain roots can cause severe problems within drainage systems ranging from repeated blockages through to complete obstructions or strangulation and collapse of the drain. The treatment of roots within the drainage system is dependent on the severity and extent of the root ingress. The vast majority of root ingress can be treated with the use of specialist root cutting equipment or high-pressure water jetting with specialist root cutting attachments. Upon removal of the roots Drainage & Hygiene Services and Clean Drain will ascertain the condition of the drain. Roots fracture the drain on entry which may cause future problems with blockages as well allowing roots to re-grow through the cracks. In most cases it is recommended that a GRP liner is inserted into the drain after root removal to seal the drain and return it to a watertight condition, the GRP liner will also help to also prevent the re-growth of the roots into the drain. In severe cases where the roots are very thick or the drain has been strangled causing the drain to collapse, the section of drain affected is removed and a new section inserted.

Drain Investigation

Drainage & Hygiene Services and Clean Drain offer a drain investigation service in the Essex & Hertfordshire areas, which incorporates dye tests, smoke tests, pressure tests and CCTV camera surveys to identify and locate problems experienced within drainage systems. Drainage & Hygiene Services and Clean Drain also offer S.O.N.D and Tracing of drains, the plotting of drainage, manhole condition reports and Invert levels.

Dye Test and S.O.N.D. Tracing

Dye tests and S.O.N.D. equipment are useful aids in tracing and determining the outfall of a drain.

Dye is a simple visual method used to confirm that a drain run terminates where the engineer suspects it does or to confirm the outfall if several possibilities exist. S.O.N.D. equipment works on the same basis as an echo sounder or metal detector. A probe (transducer) is inserted into and fed along the drain whilst a surface unit (receiver) follows the signal emitted by the probe enabling the path of the drain to be traced.

Smoke Test and Water Pressure Test

Smoke and Water Testing (Hydrostatic testing) are used to determine a structural fault in the drain such as a crack or broken section of pipe work. Smoke Testing is primarily used for above ground drainage and Water Testing for below ground drainage.

For above ground drainage, drain bungs are inserted into the drain in question and smoke applied. If there is a structural fault, the smoke will escape from the drain and highlight the position of the fault, allowing us to pinpoint the broken drain and facilitate the drain repair.

For below ground drainage, drain bungs are inserted into the drain in question. A gauge is used to fill the section of drain with water and measure the water loss over a pre-determined length of time. A dye can also be added to the water to ascertain the location of any leaks. Industry Standard calculations are performed on the data to determine whether the section of drain has passed or failed the Water Pressure Test.

CCTV Drain Survey, Drain Plotting, Manhole Condition Reports and Invert Levels

Due to the nature of drainage being underground or located in hard to reach, inaccessible areas, a CCTV camera survey is an invaluable tool in ascertaining the structural and service condition of a drainage system and plotting where the drainage flows to and from. Drainage & Hygiene Services and Clean Drain have a team of highly qualified and experienced drainage operatives who specialize in the surveying and plotting of drainage systems for the purpose of verifying the integrity and flow characteristics of a drain, to confirm position, material and duty of a drain through to house purchase/sale documentation.

A typical CCTV camera survey report will contain a detailed condition report and schematic of each drain line surveyed, manhole condition reports including the invert levels of the manholes, a site plan showing the onsite drainage, digital video footage of the drains surveyed, conclusions, recommendations and a quotation to carry out any recommended remedial works. Typically, the report is collated and sent within 5-7 working days of the survey being carried out.

Drain Leaks, Drain Excavation and Drain Repairs

Drains deteriorate over time resulting in leaks caused by ground movement, deterioration of the drain material, root ingress, corrosion and accidental damage. A myriad of techniques employing the latest technologies can be used to identify the cause, locate the position of a structural fault and to ascertain the best method of repair be it excavation and renewal, or insertion a GRP liner into the drain.

Drain Excavation, Gully Repairs and Manhole Repairs

Badly damaged drains, broken gullies, soil pipe elbows and rest-bends are excavated and repaired. Drainage & Hygiene Services and Clean Drain offer maintenance and repair services to defective manholes, manhole half channels, manhole benching, manhole walls and manhole frames and covers. All excavations and repairs are carried out to the relevant British Standard and only Industry Standard materials are used in the repair of drains.

Road and Street Opening and Sewer Connections

Road openings, for the purpose of drainage repairs and sewer connections fall under the New Road and Street Works Act 1991 Legislation. Property owners are normally responsible for the drainage up to and including the connection to the main Public Sewer. If the Public Sewer is located under a Public Footpath or in the Public Highway, a Road Opening Licence will need to be applied for. Only Street Works accredited contractors are authorised to repair and connect these drains. The application process to apply for a Road Opening normally requires a 28 day notice period following submission of the application. All necessary paper work will be handled by our specialist Road Opening Contractors. Further information on the New Road and Street Works Act 1991 can be found at http://www.legislation.gov.uk/ukpga/1991/22/contents

In-situ Drain lining and Re-lining Drains

In-situ Lining or Re-lining is a proven and established method of placing a new pipe within an existing pipe without the need for an excavation and with minimum disruption. Lining eliminates the need for costly excavations and surface disruption. Lining is suitable for domestic, industrial and municipal applications, achieves a permanent structural repair, guarantees to improve flow characteristics and will withstand ground movement far in excess of traditional drainage materials such as vitrified clay and concrete. The materials used are extremely strong, abrasive resistant and do not rely on the existing pipe for their structural strength. A lined drain will normally be ready for use the same day as installation and the process is accepted by Local Authorities, Insurance Companies, Loss Adjusters, Water Companies, Civil Engineers and Architects.

The new pipe material is similar to the glass reinforced polymer used in the manufacture of car and boat panels and is superior in quality and strength to the pipe in which it lines. The new pipe is moulded into the damaged pipe by 'inversion' using either air or water pressure, fitting it tightly against the wall of the existing pipe. When inversion is complete and the liner cured in place, the new pipe becomes rigid, fixed in place against the old pipe.

Pipe Bursting and Re-Rounding

In certain conditions where an existing drain has deteriorated beyond the point where a GRP liner can be inserted, pipe bursting and re-rounding techniques can be used. A 'mole' is bored through the existing drain, leaving a channel behind the mole in which a GRP liner can be inserted, inverted and cured in place forming a new drain without the need of a costly excavation and surface disruption. An excellent example of this technique is applied with drains of Pitch Fibre construction. Pitch Fibre was used extensively within the Essex and Hertfordshire areas in the post-war building boom and has a life expectancy of between 20-30 years after which the integrity of the drain diminishes and the Pitch Fibre becomes porous. A combination of the weight of the surrounding earth and the loss of material strength eventually results in the Pitch Fibre drain being squashed flat.
