Why new-build gardens flood — and why rolling turf straight on builders' soil fails
On almost every new housing development in Ireland, heavy excavators and dumpers compact the underlying clay subsoil to an impermeable pan during house construction, and a thin 50–75mm layer of topsoil is spread on top before handover. When winter rain arrives, water cannot percolate below 75mm, turning the lawn into a bog and killing grass roots by asphyxiation.
Our local landscaping contractors solve new-build drainage permanently before laying a single roll of turf or slab:
- Rubble & compaction breaking: De-compacting the subsoil pan and clearing buried mortar, bricks and stone left during construction.
- Herringbone 80mm perforated French land drains: Trenched at a consistent gradient, lined with non-woven Terram geotextile (so clay silt never clogs the pipe), filled with washed 20mm pea gravel to within 150mm of the surface, and connected into your storm-water inspection chamber or soakaway.
- extending the developer's tiny patio: Developers typically lay only 6 to 9 concrete slabs outside the French doors. Lifting those basic flags and laying a 25–35 m² porcelain or sandstone dining terrace at a flush or single-step threshold transforms how your kitchen-diner connects to the garden.

New-build garden & drainage questions
How much does garden landscaping cost in Ireland in 2026?
In 2026, a standalone 25–35 m² natural stone or 20mm outdoor porcelain patio costs €95 to €165 per m² (€2,400 to €5,700 installed). A standard suburban back-garden makeover (50–80 m²) including a new patio, screened topsoil, roll-out turf lawn (€22–€42/m²), sleeper beds and French land drainage typically costs €3,800 to €9,800. Complete architect-led garden transformations with split-level retaining walls, composite decking, pergolas and outdoor lighting range from €10,000 to €25,000+. All supply-and-install quotes include 13.5% construction VAT.
What is the best patio stone for the Irish climate — porcelain, sandstone, granite or limestone?
20mm vitrified R11 outdoor porcelain (€115 to €165/m²) has less than 0.5% water absorption, meaning green algae, moss and red wine cannot penetrate the slab and it wipes clean with a light wash. Silver granite (€110 to €155/m²) and Kilkenny blue limestone (€115 to €160/m²) offer classic Irish architectural character when sealed with an impregnating breathable sealer, while calibrated Indian sandstone (€95 to €130/m²) is the most cost-effective natural stone for warm buff and grey tones.
Why must porcelain and natural stone slabs be laid on a full mortar bed with slurry primer?
Never let a contractor spot-bed ('dot and dab') patio slabs on five blobs of mortar. Spot-bedded flags rock, trap water underneath in winter frost, and leave hollow voids that crack when stepped on. Every patio should be laid over a 100–150mm compacted Clause 804 stone sub-base on a full 35–50mm wet grit-sand and cement bed, with the back of each slab coated in Polymer SBR bond-bridge slurry primer so it locks permanently to the mortar.
How do you fix a waterlogged new-build garden with heavy builders' clay?
New-build estates across Ireland often have compacted subsoil smeared by heavy site machinery under a thin 50mm scrape of topsoil. Simply rolling new turf on top fails within one winter. The permanent fix is to excavate 80mm perforated French land-drainage trenches wrapped in non-woven geotextile membrane and filled with washed 20mm pea shingle discharging to the storm-water soakaway or ACO channel, deep-rotavate grit sand into the subsoil, and import 100–150mm of screened sandy-loam topsoil before laying turf (€3,800 to €8,500 for a typical new-build plot).
