Engineered Drainage for the Wettest Soils in Ireland
When heavy downpours overwhelm your property's ground, standing water can quickly penetrate rising walls, rot timber floors, and cause structural subsidence. A botched drainage line without adequate fall (minimum 1:40 or 1:60 fall ratio) results in recurring silt blockages, foul odors, and backed-up gullies.
Elevate Roofing & Building combines mechanical mini-digger excavation, optical rotating laser levels, and certified underground drainage materials to guarantee swift, permanent water runoff:
- Stormwater Attenuation & Soakaway Crates: Installing modular high-capacity stormwater crates wrapped in non-woven needle-punched geotextile fleece, buffering thousands of liters of flash rainfall without flooding lawns or drives.
- Sewer & Wastewater Pipework: Installing 110mm and 160mm certified PVC-u ring-sealed pipes bedded in 10mm pea gravel, ensuring zero joint slippage or tree root penetration.
- Perforated French Drains & Land Drainage: Excavating perimeter cut-off trenches lined with Terram fabric and washed stone to lower high water tables around foundations and sports grounds.
- Driveway Aco Channels & Rainwater Gullies: Fitting cast iron and composite linear channel drains across driveway entrances and garage thresholds to intercept rushing surface water.
What Our Pipe Laying & Drainage Service Includes
Storm Soakaway Crates
Modular underground attenuation cells designed to store and slowly dissipate storm surges into deep permeable subsoil.
Laser Fall Grading
Using rotating laser sensors to ensure every millimeter of underground pipe maintains continuous, self-cleansing gravitational fall.
Certified PVC-u Piping
BBA-approved 110mm/160mm solid and twinwall pipes resistant to high ground load, ground movement, and chemical corrosion.
Inspection Chambers
Easy-access polymer and precast concrete inspection manholes with airtight sealed screw-down lids for effortless rodding.
French & Land Drains
Deep agricultural and garden trenches backfilled with clean washed drainage stone to intercept sub-surface water.
Aco Channel Interceptors
Flush-fitting pedestrian and vehicular-rated drainage channels across garage fronts, patios, and sloping tarmac driveways.
Our 4-Stage Drainage Installation Process
Ground Topography & Fall Calculation
We survey site elevations using optical laser levels to calculate optimal falls and locate utility lines before excavation begins.
Mechanical Trench Excavation & Bedding
Our tracked mini-excavators dig clean, stable trenches. A 100mm bed of pea gravel or crushed stone is laid and compacted to cushion the pipes.
Pipe Assembly & Chamber Connection
Pipes are lubricated and fitted with elastomeric ring seals, connecting precisely to inspection chambers, trapped gullies, and soakaway manifolds.
Water Flow Testing & Final Reinstatement
We perform full hydraulic flow tests to verify rapid discharge, backfill with drainage aggregate, and reinstate turf or hardcore to perfection.
Frequently Asked Questions
County Leitrim's notorious heavy clay soil has extremely low percolation rates. When gutter downpipes discharge directly near exterior walls or surface water has nowhere to flow, it saturates the clay against your foundation, forcing damp through sub-floors. Installing a perimeter French drain and piped soakaway system channels this water safely away.
A French drain is a perforated pipe embedded in washed gravel that collects ground and surface water over a long linear run (e.g. along a lawn or driveway boundary). A soakaway is a deep underground containment system (modern geocellular plastic crates) that stores huge volumes of water piped directly from roof downpipes before allowing it to naturally soak into deep soil.
Yes. We install Aco-style polymer concrete channels with galvanized steel or cast iron heelguard gratings rated from A15 (pedestrian) up to B125 and C250 (commercial vans and heavy domestic vehicles), bedded in solid concrete haunching.
Yes. Older properties frequently suffer from cracked salt-glazed clay pipes invaded by tree roots. We excavate damaged sections, replace them with smooth-bore PVC-u pipes and flexible rubber shear-band couplers, providing permanent, trouble-free sewage flow.
