Soakaway Installation & Repair for Hullhomes & businesses
A soakaway takes the rainwater from roofs, drives and paved areas and disperses it gradually into the ground, instead of overloading the sewer or pooling on the surface. When one fails, or a property never had one, the signs are waterlogged lawns, standing water after rain and gullies that back up in every downpour.
Whether a soakaway will work, and how big it needs to be, depends entirely on the ground it sits in. We start with a percolation test rather than a guess, then design and build crate or trench systems sized for the actual water volume and soil, so the system keeps working through a wet winter rather than just a dry week.
In Hull this matters more than most places. Hull relies heavily on pumped land drainage and tidal outfalls because gravity alone can't move water away; when pumps or drains are compromised, flooding follows fast, as the devastating 2007 floods showed. The high water table means any damaged pipe quickly takes on groundwater and silt, and surcharge/backflow protection is routinely needed. Our engineers know the ground around the Humber Estuary and the River Hull, so soakaway installation here starts from local knowledge, not a generic script.
How we handle soakaway installation in Hull
Test the ground
A percolation test establishes how quickly your soil actually drains, which decides the design and whether a soakaway is viable at all.
Design & size
Crate, trench or basin systems sized to the roof and surface area they serve, built to current regulations.
Install
Excavation, membrane, media and backfill done properly, with the connecting drainage laid to the right falls.
Prove & reinstate
We test the completed system takes water as designed and reinstate the ground we opened.
Percolation tested
Designed from measured ground conditions, not assumptions.
Flood relief
Takes surface water away from buildings and paving.
Repairs too
Existing silted or collapsed soakaways dug out and rebuilt.
Straight answers on soakaways around Hull
There is no point being vague about this: Hull is one of the hardest places in Britain to make a soakaway work. The city is among the lowest-lying in the country, much of it around the level of the Humber, and a soakaway needs unsaturated ground to accept water. Where the water table already sits near the surface, as it does across much of the area for much of the year, there is simply nowhere for the water to soak to.
Conditions are not uniform, though. Ground rises gently west of the city, and plots around Cottingham, Willerby, Anlaby and Hessle can behave very differently from streets closer to the River Hull, sometimes differently from the garden next door. The season matters as much as the postcode: ground that takes water freely during a summer test can be saturated by midwinter, which is precisely when the soakaway is needed most.
This is why percolation testing before design is not a formality around Hull, it is the whole decision. We test, we look at what the ground is doing at its wettest, and we let the numbers decide. Where a plot passes, the system is sized honestly for the water it must take. Where it fails, we tell you straight rather than installing something that will spend every winter as a pond, and we put the same effort into the alternative: attenuation with a controlled discharge, a pumped arrangement, or another route for the surface water that suits the site.
Whatever the test shows, the terms stay the same: a fixed price agreed before work starts, directly employed DBS-checked engineers doing the work, and 24/7 emergency cover behind it. In a city that depends on pumped drainage to stay dry, surface water has less margin for error than almost anywhere in Yorkshire, so getting the design right first time around Hull is not perfectionism, it is the minimum the ground demands.

Soakaway Installation & Repair in Hull: FAQs
Will a soakaway work in Hull?
It depends on your ground, which is why every Hull job starts with a percolation test. Where the soil drains too slowly for a conventional soakaway we say so, and set out the alternatives for getting surface water away.
My existing soakaway has stopped working. Can it be fixed?
Often, yes. Older Hull soakaways silt up or were undersized from the start. We investigate, then either refurbish the existing system or replace it with a correctly sized modern crate system.
How disruptive is installation?
A soakaway needs excavation, but it is planned and short-lived: most domestic installs in Hull are dug, built and reinstated in a matter of days, with the ground made good afterwards.
Does the time of year affect a percolation test in Hull?
Greatly, and around Hull it can change the verdict. Ground that drains acceptably in a dry summer may be saturated from below all winter, so a result read without allowing for seasonal groundwater flatters the plot. We interpret tests against the wettest months, because a soakaway that only works from May to September does not really work.
The ground near my Anlaby home has failed a percolation test. What now?
You still have options. Surface water can be held in an attenuation tank and released at a controlled rate, or pumped where gravity cannot help, depending on what suits your plot. Failed tests are common around Anlaby and the wider Hull area and are no reflection on your property; we design for the ground you have, with a fixed price agreed before work starts.
