Why Choosing The Right Design, Drainage & Access Specification is Paramount

July 2022

Choosing your drainage and access products

When choosing drainage and access products, you often have a whole range of competing considerations and demands. There is a budget for the project, but you also need to balance this with the design and specification details. Some clients may request you consider other factors too, such as appearance and environmental considerations. The most crucial factors to consider are the specification and design of the product. Not only does the product need to be “up to the job” you’re asking it to do, and compliant with regulations, but it will also need to do it safely. This is the one area where you cannot make compromises.

Considering the crucial specifications

One of the most important considerations with drainage and access products is the loading class. Whichever product you choose must have a rating which will cope with the loads that it will be under. For example, drainage on a domestic driveway has very different requirements to those in an airport or dock, which have to endure the heaviest loads regularly.

It is always best to err on the side of caution and choose a higher loading class if you have any doubts. These loading classes are a safety feature and it’s therefore paramount that this takes priority over other considerations such as cost.

Another important consideration is the capabilities of the product. Will it be able to deal with the environmental pressures it is under? These can vary depending on where you are fitting the products. For example, you might fit drainage to an area which experiences extreme temperatures or high rainfall. Alternatively, it might need to be kept hygienic or be able to cope with a range of chemicals.

Not taking these factors into consideration could mean you end up with a product that fails to work in the environment it’s used. This has both cost and safety implications.

Deciding on design

Once you’ve found the right specifications, you can then consider design factors. Your client might be keen to choose aesthetically pleasing or eco-friendly products. However, design features which ensure a product can perform at optimal levels should be the priority. For example, products such as drainage channels will need to offer you the flexibility you need to fit it correctly. They will also need to be the right size for the amount of water that will flow through the area. The last thing you want is to order a product and then discover it’s not suitable or won’t perform at its optimal level. Not only will this cost more money in the long run, it can also put people, vehicles and buildings at risk.

Only then, once you’ve ensured a product meets safety and performance requirements, should you then move on to other considerations, such as costs.

Why getting it right is paramount

Sometimes, competing factors can cause you to consider downgrading safety or performance features of drainage and access products. For example, if you’re on a tight budget, you might choose a linear drainage channel with a weight load class that suits the area 99% of the time. Perhaps you might choose one which has a through-flow rate that just covers the rainfall or water flow the area has seen to date.

However, not having the right specifications and design can lead to catastrophic consequences. For example, global warming means we are experiencing more extreme weathers with floods becoming ever more common. A through-flow rate that is sufficient now might not be adequate in just a few years’ time. It’s not just floods that create risks, either. For example, even small amounts of standing water can increase the chances of someone losing control of a vehicle.

Ultimately, when a product is not “up to the job”, it puts people in danger. Even in less extreme cases, a product with the wrong specifications or design will cause issues and eventually, need replacing. The costs involved in this are far more significant than those involved in choosing the right product in the first place.

Don’t forget, Clark-Drain is ‘grounded in expertise’. We understand how fundamental it is to choose drainage and access products with the correct specifications and design. Therefore, we are always on hand to advise you on the best product for your project.

Rising to the Challenge: Introducing our Inspection Chamber and Riser Range

June 2022

Clark-Drain is known for providing high-quality drainage solutions and products made in the UK. Grounded in expertise, we develop products which meet regulations, reduce impact to the environment and make your work easier. This includes our range of products for mini-inspection chambers.

We specifically design these for shallow drainage and include features which are crucial for sewage adoption. We’re sharing the details of our most popular products which offer the flexibility you need to find the right drainage solution. Let’s start with our inlet chambers.

Inlet chambers for mini-inspection chambers

The most popular chamber in our range is the CD U353. This is a 5-inlet chamber with a stepped design and inlets at different depths, offering complete system flexibility. You can simply block off any unused inlets with the easy-fit bungs. We make this product from polypropylene and EPDM rubber, so rust isn’t an issue, but you still get a tough product that’s up to the job. While only weighing 2kg, it has a load rating of 35kN.

We’ve designed this product to work in perfect harmony with our risers. Combining this inlet chamber with our 400mm riser will give you the maximum 600mm depth needed for sewage adoption.

On some occasions, our 3-inlet chamber, CD U351, might be more suitable. This has a 3-way non-stepped design for change of direction applications. Like our 5-inlet chamber, it is also made from recycled polypropylene and rubber and is designed to work with our risers to not exceed 600mm depth.

Inspection chamber covers

It’s crucial that you also pick the right cover for your inspection chamber, especially when it comes to meeting load rating requirements. Our CD300 cover is the perfect partner for our 5-inlet chamber. It is also made from polypropylene and has a load rating classification of 35kN, making it a suitable choice for domestic driveways. It is ideal for areas where there is tarmac, grass or gravel, and its square-to-round design also means you avoid the need to cut paving around a circular opening. Using our expertise, we’ve ensured that it is quick and easy to install.

Of course, we also have manhole covers for other load ratings, too. If you’re looking for something with an A15 rating, we have the CD356 with its square-to-round design, or the CD352 round cover. For those wanting something capable of a little more, there is our B125 Circular Cover and our B125 Square to Round Cover. We make all of these from polypropylene except the B125 Square to Round Cover, which is made from ductile iron with a polypropylene frame.

Risers for inspection chambers

Finally, we come to our inspection chamber risers. Our most popular one is the CD U355 which is a 400mm riser. This has been designed to pair perfectly with our 5-inlet chamber to create the maximum depth allowed of 600mm with just one unit. You can easily reduce the depth of this chamber by cutting it with a fine-tooth saw and a reduction of 100mm is the maximum recommended. Like many of our other products, this chamber is also made from recycled material.

If you are looking for something shallower, then we also have our CD U354 190mm High Riser. Combined with our 5-inlet chamber, this creates a total depth of up to 400mm. Again, this can be cut easily with a fine-tooth saw with a maximum recommended reduction of 100mm.

How to access expertise and advice

If you’re installing a mini-inspection chamber, then Clark-Drain has the right products for you. All of our designs are grounded in expertise, which dates back nearly 60 years, and our technical knowledge means we can help advise you on the best products for your project.
