About Us


Seaqual (Pty) Ltd is a 100% South African owned plastic injection moulding company with its head office and factory in Knysna. We design, manufacture and distribute plastic drainage solutions that are installed by plumbers and DIY enthusiasts in residential and light commercial construction projects throughout South Africa and elsewhere in Africa and Mauritius. We have an exclusive agency with Mufle Italy for a stylish range of light-duty channel drains and manufacture a range of innovative pipe anchors used to secure plumbing and electrical pipes to any type of surface.

We are a registered importer and exporter with ISO 9001 certification.


Important Facts

The business was started when a master plumber of 37 years teamed up with a businessman to design and patent what is now Seaqual’s flagship product, the RainDrain. Our products are intended to make the plumber’s life easier by finding practical ways to solve functional and installation problems experienced on site. As a result of their innovative design, our products fulfill niche areas in the plumbing market and have become synonymous with quality, reliability, functionality and affordability.


The name Seaqual is derived from “sea” and “quality” because our products are engineered to maintain their functionality, reliability and quality under the harshest of coastal weather conditions. After 17 years of dedication, passion, reliability and consistent service we are recognized as a leading brand and a respected supplier in the South African building industry.


Every product range has been thoroughly tested for consistency, material stability and durability, mechanical strength, hydrological performance and functionality and our WetFloor and Full-Bore range has been certified by Agrément SA.


Our R&D team has many years of experience in the building industry and has identified the following as problems experienced on a daily basis by plumbers and builders when installing drainage solutions on site:


- Products are difficult to install
- They take too long to install
- Breakages, loss and theft are on the increase
- Poor quality and reliability results in too many comebacks


    With this in mind, Seaqual’s R&D team gives careful thought to incorporating practical ways to solve these problems to make the life of a plumber and builder easier. Examples of how this has been achieved are listed below:


    - Incorporation into our RainDrain of a water collection sump with a 75mm profile to match that of a brick paver, all of which fits neatly
      into the 100mm waste pipe.  This eliminates the time consuming need to build a gulley and makes for a neat and efficient finish
    - Our WetFloor drain 1st fix has the widest water proofing flange to accommodate either cementitious or bituminous water proofing
    - A 75mm SANS compliant water trap that combats back flushing, prevents odors and can be removed for cleaning
    - BuddyBats have a clip-on mechanism that reduces pipe shudder and copper theft. A single anchor halves the time to install.
      Installation breakage is zero and - Bats are color coded to identify hot and cold water pipes.
    - Our HyDrain is much lighter, much easier to install and a lot less expensive than the full bore
    - Costs associated with stock loss, theft and breakages are largely eliminated by introducing a 1st and 2nd fix option and contractors can
      improve and mange their cash flow by timing their purchases to align with the wet and dry-works requirement stages of a project


      As a result, the product range has filled gaps in the market place and Seaqual has become known as the premier supplier of reliable and affordable drainage solutions that are aesthetically pleasing and are designed, manufactured and supported in South Africa to the highest standards of quality.

      Every product in our range has been thoroughly tested, mechanically, practically and competitively and has been used by the plumbing and building industries for many years.

      Corporate Social Responsibility:

      We have a highly developed sense of social responsibility towards the Knysna community. One of Seaqual’s Directors, Richard Sohn, has been the chairman of an NGO, the Knysna Education Trust, since 1993 and was awarded the Paul Harris Fellow Award for his contribution over the years. The trust focuses on uplifting disadvantaged children by ensuring their attendance at recognised pre-schools, that they are well fed and cared for and stimulated in preparation for their introduction into the Government School system.

      The Knysna Education Trust’s website is: http://knysnaedutrust.co.za, which will indicate the nature and extent of the projects they have undertaken and the extent of their past and present successes. The Trust is not only supported by Knysna Rotary but several large corporations, the Irish community and National Lotto.



      Our products are made from ABS, polypropylene, glass-filled nylon, natural rubber and 316 marine grade stainless steel.

According to the “Green” experts, we have a “neutral” green rating. No PVC is used in the manufacture of Seaqual products.



      Our products are designed with the following criteria in mind: market demand, SANS requirements, does it solve a problem, ease of installation, quality, reliability and cost effectiveness.

      Seaqual obtained Agrément SA certification of its WetFloor F-Box Drainage Systems including the LoLo Drain Product Range as well as its HyDrain Full-bore product Range including BalconyDrain four years ago. Agrément SA deems the products fit for purpose when used and installed in accordance with manufacturer’s applications and installation instructions. This makes Seaqual the only SA manufacturer of plastic wet-floor and full-bore drains that have been certified by a recognized government authority

      Seaqual Manufacture

      Along with product patents, Seaqual has designed and owns the moulds and injection-moulding machines used to manufacture the plastic components needed to create their products. We outsource production of the stainless steel components and assemble and package these components, together with those made in our own factory, to form the recognized brands in the Seaqual range.

      The Seaqual range of products consists of:


      WetFloor Drain:     

      Floor drain with 75 mm SABS compliant water trap available with a choice of attractive grate patterns. Tested by Agrément SA and found to be fit for purpose for use in all Pipe Systems described in SANS 10252-2 Table 19. Certification No: 2017/541


      TileGrate 2nd Fix:

      Our “hidden” floor drain, TileGrate, gives a complete floor tile finish effectively “hiding” the drain. The cover tile is easily removed to clean the water trap or for maintenance should it be required. Can be used as an internal or external drain. TileGrate is a 2nd Fix pack and needs to be specified with a 1st Fix in order to make up a complete drainage unit.

      Consists of a domed leaf guard and waterproofing flange for use on flat roofs to lead water into 110 mm storm water drainage pipes. HyDrain is a popular option for plumbers who prefer it to cast iron full bores that are cumbersome to work with, difficult to install and considerably more expensive. Tested by Agrément SA and found to be fit for purpose.

      Certification No: 2017/540.



      Available in 2 sizes, 110x110mm and 200x200mm with 50 & 75mm, side or bottom outlets with a range of finishes. For use in all areas where a water seal is not required such as patios, balconies, flat tiled roof decks etc. Tested by Agrément SA and found to be fit for purpose.

      Certification No: 2017/540



      Our flagship product is installed at the base of gutter downpipes, in gardens, atriums, walk ways, paved areas and golf courses to lead water into a 110mm storm water system. We produce this product in polypropylene for pedestrian traffic use and nylon reinforced UV resistant plastic for areas that carry vehicular traffic such as parking bays or driveways.


      BuddyBats & BuddyClips:

      An innovative system for anchoring plumbing and electrical pipe conduit to any surface. Unlike other products on the market, BBs are quick and easy to install, reduce water hammer, no breakage/wastage when installing, come in a range of colours and sizes and reduce the incidence of copper theft because of their unique lock-in mechanism. Suitable for installation using a nail and anchor or a pozi screw. Once mounted, pipes can easily be accessed to perform maintenance or rerouting by simply removing the pozi or nail. .



      DrainMate consists of a 40mm Grate & Waste, as above, combined with a plastic 40mm adjustable P-trap. It is an entry-level product, ideally suited to low cost housing projects where strict budgets need to be adhered to. DrainMate is a popular for DIY enthusiasts as it is simple to assemble and easy to install.



      A tileable inspection hatch intended to save money by enabling quick and easy post-installation access to pipework, junctions, pumps and motors used in the installation of built-in baths and jacuzzis. No irritation due to damaged tiles that may are longer be available at the tile shop, no dust and rubble associated with the need to chop tiles and cement, saves time and most importantly the cost of labour and new tiles.  The removeable section also accepts, screed, wood and wallpaper finishes which provides the installer/interior decorator/home owner with multiple options.


      Ceiling Saver:

      Prevents indoor flooding during vacuum breaker failure (burst geyser) which a drip tray cannot prevent. This handy device can literally save you thousands of Rands in damages. It encapsulates the two vacuum breakers on a geyser / boiler and leads water directly to the exterior of a home via an outlet pipe in the case of vacuum breaker failure.


      4All Channel Drainage System :

      3 X 1m linear channel drain lengths wrapped in a “garage pack” specifically intended for the DIY market. Available in a galvanised steel or black HDPE grate finish and imported from Italy. Accessories include stop ends, bottom outlets and Drain Boxes. These are required to create  junctions, 90deg bends or T-pieces. 


      QualiDrain Channel Drainage System:

      Unique features highlighted in bold. Launched in February 2020, this innovative and novel channel drain is used to control the flow of external surface storm water. It’s simple click-in system enables channels to connect linearly to any desired length, in a T, L or + without a junction box, and in parallel to form a catch pit of any length and breadth by means of a simple U Connector. All components sold separately so you purchase only what is required. No wastage. Each channel is supplied with a disposable dust cover for use during installation and is replaced with the grate, which is not stained by concrete slush or sediment, once the concrete has set. Glass-filled Nylon grates are available in 5 standard colours and can be made in almost any other colour subject to availability and size of order. Grates can withstand up to 15 Tons of vehicular weight. We anticipate this product will qualify for a B125 and possible even a C250 rating when tested by Agrément SA sometime later his year.



      The Seaqual WetFloor Drain water trap components comply with the depth and quality of the SABS specifications. 

      Our WetFloor and Full-Bore range has been certified by Agrément SA. 

      We have implemented a quality management system and recently been awarded our ISO 9001:2015 certificate.
