Helpofamily - a brush coating solution for internal pipe repairs

HelpoFamily is a full brush coating pipe rehabilitation solution for internal pipe coating. Helpo Family includes the HelpoFlake polyurea resin and a Relining S-system brush coating equipment. HelpoFlake is a preferable choice when a pipeline of Ø 50 -125 mm contains more than normal amounts of moisture. HelpoFlake is also highly resistant to pressure and chemicals, as well as temperature variations.

HelpoFlake internal pipe coating resin

HelpoFlake is a polyurea resin for internal pipe coating that undergoes extreme conditions

insensitivity to moisture

There might be times when all water and moisture can’t be dried out of the pipe. HelpoFlake coating can be coated in extremely humid conditions thanks to its insensitivity to moisture. Drying of the pipe is however recommendable to ensure the absolute bonding with the host pipe.

HelpoFlake polyurea coating is durable

HelpoFlake coating is made for extreme conditions. The fast curing coating has excellent chemical, abrasion and corrosion resistance, providing resistance against many known chemicals found in wastewater systems, like hydrogen sulfide gas and acids. The material can withstand mechanical shock and has excellent impact resistance.

HelpoFlake spray coating is tough but flexible

Thanks to its elasticity and flexibility, HelpoFlake coating has high physical properties like high flexural strength and pressure tolerance, as well as tensile, elongation and tear strength properties. The coating bonds to virtually all substrates, including plastic, steel, concrete etc. Thanks to its elasticity, HelpoFlake coating is ideal for substrates such as concrete that have a tendency to crack. The coating has an ability to stretch and bridge gaps and the coating is not limited to variations of temperature, as the substrate expands or contracts under these conditions.

Efficiency – Save valuable time

Like ElastoFlake, HelpoFlake coating sets and cures quickly, eliminating the need for an alternative service line. The coated pipe line is ready for service after coating.

Internal pipe coating made easy with Relining S-system

The Relining S-system is especially designed and developed for use with HelpoFlake polyurea resin. With our Relining S-system we have given special attention to the usage and maintenance of the systems.

Low start-up cost: great way to enter spray coating world

Relining S-system is suitable for small coating projects, where only one or two lines (with pipe diameters from 50 – 130 mm and for maximum 7 meter pipes) or a hole needs to be patched. This makes it a perfect option for companies that don’t require a full lining or spray system. The Relining S-system has a relatively low start-up cost compared to CIPP lining or full spray systems, and the system can pay for itself within the first couple of jobs.

Easy and effortless way to coat sewer and drain pipes

The Relining S-system is extremely easy and quick to set up: no long training or experience is needed to start the coating. Following a quick setup training about cleaning and coating the pipe and the user instructions of the system, the installer is ready to start work.

Also, usage has been designed to be effortless and clean since the system uses disposable cartridges instead of fillable tanks.

Easy to transport

The Relining S-system coating system is designed to make the on-site workflow as easy as possible. The compact unit is easy to transport to and move around the renovation site, saving time and effort.

Technical features of the relining S-system

  • Height: 695 mm
  • Width: 775 mm
  • Depth: 175 mm
  • Weight: 35.75 kg (without cartridges)
  • Materials: aluminium and polycarbonate
  • Pipe Dimensions: Ø 50 mm – 125 mm
  • Working distance: max. 7 m
  • Supply current: 240 V AC (possibility of 110 V AC)
  • Constant rotational speed: 2400 / 1 min
  • Resin output speed: adjustable, two options
  • Electrical clutch for the user safety
  • Control panel with emergency switch
  • Wireless remote control with emergency switch
  • CE-marked
  • Material usage chart is delivered with the system for easy quality control
  • Video instructions for ease of setup and use
  • Very minimal material waste and minimal maintenance after using the system, thanks to its disposable cartridges
  • Quick set up time: less than 5 min and the Relining S-system is ready for use

Frequently asked questions

Polyurea is an elastomer substance derived from step-growth polymerization, which involves combining a synthetic resin and isocyanate reactive materials. These fast cure, waterproof, no VOC, no odor coatings are suitable for use in a broad range of industries, thanks to their characteristics: moisture insensitivity, thermal resistance, weathering and corrosion resistance and resistance to chemicals and abrasion. They are used for example as floor and wall coverings, pipelines or construction equipment coatings.
Also, because of their elasticity, polyurea coatings are ideal for substrates such as concrete, which tends to crack. As an elastomer, these coatings have the ability to stretch and bridge gaps up to 1/8 inch.

A cold spray coating is possible, no heat is needed during the application to ensure the polyurea will cure. The polyurea coating can be applied to almost any thickness on any diameter of length of the pipe.


The pipe coating will last for several decades, but the operating life depends of many factors: the replacement pipe material, the coating material, the usage and maintenance of the pipeline as well as how the coating rehabilitation was performed. On average, with normal use and with pipe coating rehabilitation done properly, Relining Groups spray pipe coating will last for several decades. To date, we’ve determined that most polyurethane or polyurea projects will last between 30 and 50 years, or about the same amount of longevity you could expect from having all the pipes replaced with new ones.

Like polyurethane, polyurea is also a very fast curing resin compared to epoxy and it will cure in minutes after the application. Unlike polyurethane, insensitivity to moisture is the great advantage of polyurea. Polyurea coatings are also known for their ability to adhere well to a wide variety of substrates in a broad range of temperatures.

Polyureas appear to have better elongation and tear strength as well as resistance to chemicals and abrasion, than epoxies where as epoxies provide more toughness. Because of their elasticity, polyurea coatings are ideal for substrates such as concrete which has the tendency to crack. As an elastomer, these coatings have the ability to stretch and bridge gaps up to 3mm. Due to this flexibility, polyurea coatings are not limited by extremes of temperature, while rigid coatings like epoxies tend to crack as the substrate expands or contracts under these conditions. However, epoxies have better ring stiffens properties than polyurea because it lacks the elasticity.

Another downside of epoxies is, that epoxies are formed by reacting bisphenol A with epichlorohydrin, and then cured with amines. Use of Bisphenol A is widely forbidden in many products because it is health dangers.

Polyurea pipe lining is safe and its being approved as an eco-friendly low volatile organic compound coating (low VOC). Substitution of epoxies and other coatings by eco-friendly polyurea coatings is expected to cause a spurt in demand for polyurea.
