New Soakaway Installations
Surrey and the South East

Are you looking for new soakaway installations in Surrey and the South East? A soakaway is usually built below lawns, driveways or patios over five metres away from the building. 

Call today on 01483 377 074.


Much like septic tanks and cesspits, soakaways are created and installed outside of your property to attract excess rainwater away from causing damage to your home or business. The soakaway is a large hole that can fill with bricks, hardcore or other significant bits of debris.

Modern soakaways constructs from plastic crates known as a Modular Cell Drainage System. 

A soakaway is usually built below lawns, driveways or patios over five metres away from the building. As rainwater collects within roof gutters or drainage channels, it gets transported towards the soakaway.

When water begins to fill a soakaway, the voids draw the water inside, starting to soak away gradually into the ground. It helps homes or other buildings from becoming waterlogged or flooded during periods of heavy rain. 

It would be best if you only used a soakaway for use with rainwater. They are not for human waste disposal.

New Soakaway Installations Surrey and the South East

Planning A Soakaway Construction

The ground's design and mechanisms can significantly affect the job and efficiency of the soakaway installation. Anything that holds lots of water is not helpful for the construction or instalment of a soakaway. For example, clay will absorb any water, thus creating large puddles. However, certain soil types may be better as water is kin to seeping through the soil in the grass or plants. 

Frequently Asked Questions

Many properties have separated drains that each cope with any surface waters and wastewaters from your property. It is your responsibility as a homeowner to recognise these connections and understand their ins and outs. The way to find out if your property has any soakaways is to request a copy of the property land's deeds.

You can do this through GOV.UK, you register your property details and pay up to £3.00, and they shall send you a copy of the HM Land Registry form, which entails the current and previous information of the land. You may also wish to apply for an Environment permit or look at your original planning application for details on the drainage layout. Feel free to call or contact us for any further information on how to identify your soakaways and keep up their maintenance.

There are risks to having no surface water drainage, especially in the local Surrey area and elsewhere in the UK when we experience storms and so much rain in months, not just years. Your property can be susceptible to flooding and waterlogging. Should you not have access to surface water drainage, the water on the surface can seep down in the drains and not get trapped above. Or can cause sewage damage if absorbed below and cause sewage treatment plants to be installed. 

Many local authorities and engineers recommend have regulations on the distance and location of soakaways. The Soakaway or drainage systems be at least five metres away and from a building's wall. If you are dealing with a boundary, it must be at least two and a half metres far from that. Doing so prevents problems with rainwater flooding your or your neighbours garden or property and prevents subsidence on your walls and surrounding areas. 

To determine the size of a soakaway, you must consider the water volume to drain through to the water table. The percolation rate of the soil is highly critical. To test it, you can; see if you detect a foul smell; dense soil can often smell bad. Another way to find out is to check the colour; well-drained soils tend to be reddish-brown and over-saturated grounds are blue-grey.  

Replacing a soakaway

There are a number of reasons why you may wish to replace your soakaway with a new one:

  • Your existing soakaway may have become blocked. When mud, leaves, plant roots or other materials have blocked your soakaway, it may require replacement.
  • The soakaway might have collapsed. It can happen if heavyweights such as lorries, cars, tarmac, or concrete are above them.
  • You may require a larger soakaway for a house extension. The additional water collected in the roof guttering may become too much for the existing soakaway when extending a house.
  • Building a new driveway requires provided adequate drainage to collect surface rainwater.
