Building regulations across the UK have drainage solutions in place to align with compliance measures and prevent rainwater buildup. But there are times when a balcony drainage system will lack controlled drainage. With this in mind, what can you do if your balcony drains are blocked?

The implementation of free draining balconies represent the best drainage solution for blocked balcony drains. Furthermore, a grooved decking board can also be used to reflect and repel rainwater off of the balcony thanks to the structure of the boards.

At KJC Drainage, we excel at providing drainage solution systems for blocked drains, which can keep your balcony free of water and your balcony’s structural integrity intact.

Read on to find out more about what to do if your balcony drains are blocked and how we can help.

What is balcony drainage?

Balcony drainage is a type of effective drainage that limits standing water build-up and frees moisture saturation from the balcony space.

Finding the right solution is crucial to promoting positive drainage since balconies are consistently exposed to the outside elements. For buildings that have flat roofs, balcony drainage systems are also important since no overlap of the roof can catch the rainwater.

This is why a balcony drainage system that is contoured to the specifics of your balcony is important since even with regulations in place, blockages can still occur over time.

Types of balcony drainage systems?

There are a few different kinds of drainage types to consider for balconies.

Something like a suspended deck structure like an ACO FreeDeck, can work wonders for catching the rainwater and adequately moving the flow along terraces or eaves of a building.

There is also the option of a funnelling system via a piped drainage setup that can siphon rainwater from a balcony and move it along the property plumbing system, usually through downpipes.

Some of the main factors to consider for reflecting rainwater is the spillage that can occur on the ground below or, underneath a neighbours balcony.

In these situations, strong consideration should be given to the construction of a guttering system to move the water along to an appropriate drain.

Furthermore, the maintenance of the guttering system is important to the overall smooth running of balcony drainage. Consider, using gutter cleaning services to provide upkeep.

No matter which system you choose, it is important to ensure water is not causing a blockage since this can lead to structural damage.

Do all balconies have drainage solutions?

Most balconies do have some kind of drainage system or water ingress to ensure damage to the balconies’ surface, edge, or structural spaces is prevented.

For example, if a balcony is made of concrete, there is typically a special type of waterproof membrane added to the surface of the concrete to reflect water. These balconies are typically found on a building with flatter roofs.

Additionally, many balconies have an overflow pipe added during the construction process to ensure the spaces of the balcony, as well as the access point to the balcony, are free of water and maximise safety over risk.

There are many components of the structure of a property to ensure drain points installed near a terrace can deflect a majority of water, but blockages can and do still occur with the passage of time.

How do I maintain balcony drainage at home?

The most proactive things you can do to ensure your balcony’s drainage system stays unblocked are to ensure doorways are clutter-free and there are very few personal items on the balcony.

The more area available for the water to access drain pipes on the building, the better.

Another thing to consider is the guardrails connecting the drainage pipes are fastened and secure to allow a sturdy connection to your balcony.

Water should also be swept off of raised tiles if your property has these. Pools of water can sometimes collect on the edge of the cracks and crevices of tiling. Simply sweep it along to your garden below to prevent moisture retention.

If water is falling onto your balcony from the upper façade of the building, talk to the business manager of your property to request they address the issue and protect your balcony and their investment.

These are just some of the solutions you can consider to protect your house façade and ensure your balcony’s drainage system remains unblocked.

When should I call a professional when the balcony drainage system is blocked?

If you simply cannot unblock the draining reservoir, then you should consider calling a professional to minimise the risk of damage.

This can be during the early signs of blockage but almost certainly when the water is standing still and simply not moving from your balcony site at all.


Do balconies need gutters?

Gutters can lead water away much more rapidly than other types of drain systems. Gutters can feed the water directly into pipes and prevent any spillage to the ground below.

Something like an ACO FreeDeck has even more benefits since this development combines both line and point drains once constructing of the deck is finished.

Gutters are typically preferred for balconies that retain water very easily or lack proper pipelines to carry the water away to the main drainage line.

How do you waterproof a balcony floor?

You can waterproof the floor of a balcony by utilising specialised types of coating that apply special membranes that contain waterproof enzymes.

Something like a polyurethane sealant does wonders for waterproofing since the sealant repels and deflects water from the site and an additional layer of primer seals the sealant even further into the surface matter.

Finally, a waterproofing membrane can be added on top to bind everything together and keep the surface of the balcony dry.

This layering can be applied as many times as it takes to ensure a continuous layer of a waterproofing membrane on the balcony floor.

How much should a balcony slope?

Much like an air-conditioner that fits through a window or a wall, balconies should be designed to slope adequately to allow for proper drainage.

Typically, and depending on the particular balcony, the balcony should slope at least one-quarter inch per foot of total space. This level of sloping ensures that water can move along the proper reservoirs properly and not pool in one area of the balcony that doesn’t slope enough.

There should be a total of at least 1% of slope to the entire balcony to maximise adequate drainage and flow of the collecting water.
