Our key differentiators
Targeted drain excavation
We identify the damaged section before digging, helping keep excavation focused and disruption to your property to a minimum.
Complete drain replacement
Where pipework is beyond repair, we remove the failed section and install new drainage to restore reliable performance.
Domestic & commercial repairs
Our excavation services cover underground drainage problems at residential, commercial and industrial properties.
Professional drain excavation & underground drain repairs
While many drainage problems can be resolved using cleaning, jetting or trenchless repair techniques, some damaged drains require excavation and physical replacement.
Drain excavation is normally recommended when underground pipework has suffered significant structural damage and cannot be reliably repaired using less invasive methods.
When a drain has collapsed, become badly displaced or deteriorated beyond repair, removing the damaged section and installing new pipework can provide the most appropriate long-term solution.
Why repair the problem properly?
Repeatedly unblocking a structurally damaged drain does not necessarily solve the underlying cause. For example, a drainage jet may temporarily clear waste from a collapsed or displaced section of pipe, but the obstruction is likely to return if the damaged pipework remains in place. Replacing the defective section addresses the actual structural problem rather than repeatedly treating the symptoms. Contact us today to learn more about our services.
What is drain excavation?
Drain excavation involves carefully exposing damaged underground drainage pipework so that the defective section can be inspected, removed and replaced.
Once the repair has been completed and the drainage system is functioning correctly, the excavation is backfilled, and the affected area can be reinstated as required.
The extent of excavation needed will depend on factors such as:
-
The location of the damaged drain
-
How deep the pipe is underground
-
The length of damaged pipework
-
Access to the site
-
The condition of the surrounding ground
-
Whether the drain runs beneath paving, concrete, landscaping or other surfaces
When is drain excavation necessary?
Excavation may be required when a drainage system has suffered more serious damage that cannot be effectively repaired through relining.
Examples can include:
-
Collapsed drainage pipes
-
Severely cracked or fractured drains
-
Badly displaced pipe joints
-
Crushed or deformed pipework
-
Large sections of deteriorated drainage
-
Significant ground movement affecting the pipe
-
Major root damage
-
Incorrectly installed drainage
-
Persistent drainage problems caused by structural failure
-
Sections of pipework that cannot be successfully relined
-
Drainage requiring complete replacement or rerouting
A CCTV drain survey can usually help identify the exact location and severity of the problem before excavation begins.
Why is drain excavation important?
A badly damaged underground drain can cause far more than an inconvenient blockage. Drainage pipes are designed to transport wastewater safely away from the property. When a pipe collapses or breaks, that wastewater may no longer travel through the system as intended.
Leaving serious drainage damage untreated can potentially lead to:
-
Repeated or complete drain blockages
-
Toilets backing up
-
Wastewater overflowing
-
Sewage smells
-
Wastewater escaping underground
-
Saturated or unstable surrounding ground
-
Increased deterioration around the damaged pipe
-
Root ingress
-
Localised ground erosion
-
Damage spreading to adjoining sections of drainage
-
More extensive excavation being required later
Where excavation has been recommended because of structural damage, delaying the repair can allow the underlying problem to become considerably worse.
Benefits of drain excavation
Complete access to the damaged pipe
Excavation allows the defective drainage section to be physically exposed, inspected and removed.
Severely damaged pipework can be replaced
Where a pipe is beyond repair, new drainage can be installed to restore the integrity of the system.
Addresses the root cause
If recurring blockages are being caused by a collapsed, displaced or badly damaged drain, excavation can remove the source of the problem.
Long-term solution
Correctly replacing seriously damaged drainage can provide a more reliable solution than repeatedly attempting temporary repairs.
Prevents further deterioration
Removing a failed section of drainage can prevent the defect from continuing to cause leakage, blockages and damage to surrounding pipework.
Improved drainage performance
New correctly installed pipework helps restore reliable wastewater flow through the drainage system.
CCTV drain surveys before excavation
Where possible, we believe drainage excavation should be targeted rather than unnecessary. A CCTV drain inspection can identify the damaged section of pipework before excavation begins.
This allows us to understand:
-
Where the damage is located
-
How severe the damage is
-
How much pipework may need replacing
-
Whether relining is possible
-
Whether excavation is the most appropriate repair method
-
By identifying the problem accurately beforehand, unnecessary digging can often be avoided.
Drain excavation for domestic properties
Underground drainage problems at residential properties can occur beneath gardens, paths, patios, driveways and other areas. If a drain has collapsed or suffered substantial structural damage, excavation may be necessary to restore reliable drainage to the property. We aim to keep excavation work focused on the affected area wherever possible and minimise disruption to the rest of the property.
Commercial drain excavation
A failed drainage system can cause serious disruption to a commercial property. Restaurants, pubs, offices, warehouses, factories, retail premises and other businesses depend on reliable drainage for everyday operations. Where major underground drainage damage is discovered, prompt excavation and repair can help reduce the risk of further disruption, flooding, hygiene concerns and repeated emergency call-outs.
Excavation shouldn’t be delayed when it is necessary
Nobody wants to excavate a driveway, garden or commercial site unnecessarily, which is why less invasive repair methods should always be considered where appropriate. However, when a drain has suffered serious structural failure, postponing the inevitable repair can increase the risk of the situation becoming worse. A targeted excavation carried out at the correct time can prevent repeated drainage emergencies and restore the system properly.
