Our surveys make thorough assessments of all types of drainage systems. With the world’s most superior recording equipment, our CCTV Mega-Cams delve into your drain giving you and our engineers the best possible response to drainage issues.
Our Mega-Cam provides the highest quality CCTV surveys and can detect settled deposits, joints displacement, deformed sewers, fractures, broken pipes, cracks and pin-point their precise location in drains and sewers. When lowered into place from a standard man-hole, the Mega-Cam can operate up to 500m from the vehicle. We can access surface water drains as well as underground culverts using cure in place pipe (CIPP). This then provides us with a map of existing sewers and connections in any given area.
For pipes smaller than 150mm (6 inches) we use an advanced push rod camera system, which consists of a camera attached onto a rod, which can be manually navigated to identify problems. This provides the same level of reporting, but is able to access smaller pipes including those in foul sewers.
The crawler unit drain camera is another remote controlled CCTV camera system we use. It has 4-wheel drive, colour CCTV inspection and is suitable for surface water drain pipes between 50mm and 300m in diameter.
Hard-to-reach sewer systems, like those built in the Victorian era, are difficult to access. We deploy our confined space teams to undertake a manual survey in order to establish what is happening underground. It is extremely dangerous and entirely illegal to enter the sewer network without permission, licensed, training and qualifications as well as a confined space rescue team back up.
HCL engineers are fully trained and qualified specialists in operating our remotely controlled cameras for pre-adoption drain surveys. Our engineers assess the state and integrity of the drain or sewer without causing any disruptions to the client, or the environment. Our engineers provide a report on any findings along with any recommendations that would resolve any issues found.
Pre-adoption surveys are also required by mortgage lenders prior to agreeing to a mortgage. This is to assure mortgage lenders that the property, for which they are giving a loan, have no hidden faults that could seriously devalue the property, and also assures the buyer of the property, that the drains are in good working order. This survey is also known as a Homebuyers’ Survey.
HCL uses the latest CCTV survey technology when carrying out pre-adoption surveys. Our cameras record HD quality videos of any issues detected within drains, using shadow-less LED lighting with 10x optical zoom and dual lasers to measure defects. Our cameras are suitable for drains measuring less than 150mm (6”) all the way up to 1000mm (40”) in diameter.
Our skilled specialist engineers are trained and qualified to operate the equipment required to undertake site surveys. Site surveys may include existing buildings, structural surveys and investigations, flood risk, air quality and historic use amongst other things. A site survey may also include a feasibility report, and estimation of cost, and time to carry out the works.
Accurate information is required from the start of a building or engineering project, and it is essential that ground conditions, and previous use of land are established at the outset. This helps to minimise risks, by providing data on which to base the concept and reduce risks in the planning stage of the project.
HCL’s site surveys shows the precise location of obstacles and boundaries to the site. This may include other buildings within the boundaries, trees that are protected, any rivers or streams, and the gradient of the land. Highlighting these at the start of the project, can save a lot of issues and hazards to the project.
Time is spent on site to complete the survey, using instruments to collect location data. This data is then analysed before a scaled drawing is completed to reflect the results of the analysis. Topographical surveys provide accurate information on the levels of the site. These surveys are usually requested, and used by architects, engineers, civil contractors, and landscape gardeners, to help them to progress with their designs or drawings.
It always pays to check your drains, septic tanks and sewers. Our trained engineers assess their condition and provide rehabilitation using cure in place pipe (CIPP) where necessary, as well as target hard to reach surface water drains with a pipe allowance of between 100mm to 750mm.
Getting a homebuyer survey is a great way to avoid unexpected repair costs further down the line. Getting a survey for a house or flat will also give you an idea of how much you might need to invest in a property after you buy it.
Conditional and connectivity surveys assess the internal condition of our drains and sewage systems unearthing any pipe collapses, rot damage or blockages. Inspecting the structural condition means that any problems can be dealt with immediately and any future problems can be avoided.
CCTV drain surveys are carried out by inserting a camera into the drain/sewer system to detect and identify any issues that could affect the performance of your drains, such as blockages, root damage or pipe collapse. Typically deployed to find and record faults within drainage systems, HCL’s CCTV drain survey can help prevent any failures in the drainage system. CCTV drain survey is used to a great extent, within the construction industry, at the point of site handover. The engineer will carry out a comprehensive evaluation, producing a report on the site’s drainage systems, verifying the integrity, cleanliness and operational effectiveness of the system. The report is vital to the assured and complete handover of a building, and could prevent on-going disputes over liabilities, should systems fail.
HCL operates one of the largest fleets of CCTV drain survey vans, in the South East. Our CCTV cameras produce HD quality video recordings of the state of your drains, highlighting and pinpointing the precise location of any issues detected within your drainage system. These cameras are able to survey pipe sizes between 50mm and 300mm in diameter and operate at distances of up to 500m, enabling our engineers to easily identify objects causing blockages or any other issues with your drains. Our CCTV operators are trained and accredited to OS19X for Piped Drains and Sewers, and OS21X for Bricked Sewers. These accreditations are a pre-requisite for all operators who prepare CCTV reports, for long term records purposes, for all the UK’s Water PLCs. Upon completion of the CCTV drainage survey, our clients are provided with a full colour DVD and a comprehensive WinCan version 8 report, alongside recommendations prepared by a fully qualified engineer. CCTV drains surveys are usually required to find faults that are affecting, or could affect, the integrity of the drains operating at the optimum levels. This service is required by those in the construction industry, councils, businesses and homeowners as well as those who are in the process of purchasing a property. The report is vital to the assured and complete handover of a building preventing on-going disputes over liabilities, should systems fail.
Conditional & Connectivity CCTV Surveys Conditional and connectivity CCTV surveys assess the internal condition of our drains and sewage systems unearthing any pipe collapses, rot damage or blockages. Inspecting the structural condition means that any problems can be dealt with straight away and any future problems can be avoided. Pre-Adoption CCTV Surveys Pre-adoption CCTV surveys are carried out by water authorities, builders, architects, developers and local authorities when buying assets, which involve drainage systems. It provides confirmation and security that the pipelines are in good condition, that no unknown environmental risks are being accepted and there are no hidden problems within the drainage systems. Home Buyer/Seller CCTV Surveys Pre-purchase homebuyer CCTV surveys are now required by most mortgage lenders, and gives peace of mind to the prospective property buyer. This can be particularly relevant if the property is older, has had refurbishment work completed, or if there have been construction activities in the surrounding area. Pre-Demolition CCTV Surveys Pre-demolition CCTV surveys help to establish drain runs, locate access chambers, and secure location prior to demolition. This is vital in protecting the drainage system, and preventing damage to the system as a result of the demolition.
Push Rod Cameras For pipes smaller than 150mm (6 inches), HCL uses an advanced push rod camera system, which consists of a camera attached to a rod, which can be manually navigated to identify problems. This small camera system is able to access narrow, smaller pipes, and provides the same level of reporting, as our other cameras. Crawler Camera The crawler unit drain camera is a remote controlled CCTV camera system. It has 4-wheel drive, colour CCTV inspection, and is suitable for pipes between 50mm and 300m in diameter. This camera system also produces HD quality reports for our clients. Mega Cam Mega-Cam is used for longer and larger pipe sections, is operated by remote control, and has advanced pan and tilt technology. This high performance CCTV drainage camera system is supplied with 500m of Kevlar-reinforced cable, with an auto self-levelling high definition (HD) colour camera and 4-wheel drive. Suitable for pipe sizes from 150mm (6") up to 1000mm (40") in diameter. All WinCan surveys are recorded with this camera’s built-in DVD, which records the condition and structure of the drainage system and is provided as a formal report to our clients.
There are more than one type of topographical survey, depending on the purpose of the survey and the desired output. These are; general land survey, boundary survey, and construction surveys. General Land Surveys Land surveys are for determining distances and angles between points on the land, and is essential for civil engineering and construction projects. Land surveys determine the three-dimensional positions of points and the distances and angles between them. Boundary Surveys Boundary surveys are used to identify a property’s boundary lines and are used as a means of formally defining the limits of properties. This is an essential part of property ownership. If boundary lines are contradictory, landowners may need to carry out a boundary survey. Boundary surveys are usually carried out prior to the purchase of land, and include the measurements of the land. Construction Surveys A construction survey is much like a land survey and involves looking at the natural habitat of the area. This survey is concerned with the layout of the project and involve markers and reference points on the site that instruct contractors where to start building a new structure.
