Professional French Drain & Herringbone Drainage Installation in Lancashire
Engineered Solutions for Waterlogged Gardens and Land
Is your property suffering from standing water that refuses to drain? In Lancashire, the combination of high annual rainfall and heavy, impermeable clay soil creates a "basin effect" in many gardens.
At Mitre Civils UK, we don't just "dig trenches." We provide civil-engineered land drainage solutions that tackle the root cause of flooding. From residential gardens in Chorley to larger estates across the North West, our systems are designed to last a lifetime.
The Science of Sub-Surface Drainage
Unlike surface-level fixes like spiking or sanding, our systems address groundwater saturation. We specialize in the two most effective methods for Lancashire's geography:
​
1. French Drain Installation Lancashire
A French drain is a sub-surface interceptor. It consists of a precisely graded trench lined with a high-tensile geotextile membrane, filled with clean, non-limestone aggregate, and housing a perforated drainage pipe.
​
-
Best For: Perimeter drainage, protecting house foundations, and intercepting runoff from neighbouring higher ground.
​
2. Herringbone Drainage System Installation
For total lawn saturation, we install a Herringbone system. This involves a central "spine" pipe with multiple "rib" pipes branching off at 45-degree angles.
​
-
Best For: Large waterlogged lawns, boggy fields, and areas with no natural runoff. This system provides maximum coverage, ensuring no "dead spots" of standing water remain.
Why Mitre Civils UK is the North West’s First Choice
As a dedicated civils and groundworks company, we bring a level of precision that standard landscapers cannot match:
​
-
Laser-Level Accuracy: We use laser levels to ensure a constant fall (gradient), meaning water always moves toward the discharge point, even on seemingly flat Lancashire sites.
​ -
Clay Soil Specialists: We understand that Lancashire clay requires specific "filter media" (clean stone) to prevent the pipes from silting up.
​ -
High-Spec Materials: We only use twin-wall perforated pipes and industrial-grade membranes that won't collapse or clog under the weight of the soil.
​ -
SuDS Compliant: Our systems are designed according to Sustainable Drainage Systems (SuDS) principles, ensuring your runoff is managed responsibly and legally.
Why Choose Us?
With our experience in the landscape industry, you can rest assured that all our works are finished to a high spec with minimal disruption throughout.
Our Installation Process
-
Site Topology Survey: We identify the natural fall of your land and locate the best discharge point (e.g., an existing storm drain, watercourse, or high-capacity soakaway).
-
Excavation & Waste Removal: Using our own fleet of mini-excavators, we dig to the engineered depth required to bypass the compacted clay "hardpan."
-
Membrane Lining: The trench is lined with a geotextile fabric. This acts as a filter, allowing water in but keeping soil particles out to prevent future blockages.
-
Pipework & Aggregate: We lay perforated pipe drainage and backfill with clean 20mm shingle to within 100mm of the surface.
-
Restoration: We finish with a breathable topsoil and premium turf or decorative stone, leaving your garden looking pristine and—most importantly—dry.
