Pembrokeshire possesses one of the most dramatic and exposed coastlines in the whole of the United Kingdom. The Pembrokeshire Coast National Park stretches for 186 miles along the south-western tip of Wales, facing the full force of Atlantic weather systems with very little shelter. Annual rainfall across the county regularly exceeds 1,400mm, prevailing south-westerly winds can reach gale force on the exposed headlands, and salt-laden Atlantic air permeates gardens and outdoor structures throughout the year.

These are some of the most demanding conditions for outdoor garden materials anywhere in Britain. Natural timber decking in Pembrokeshire can warp, crack, and rot within just two or three seasons. Composite decking boards are engineered precisely for environments like this — moisture-proof, salt-resistant, UV-stable, and requiring no annual maintenance. They are the outstanding long-term choice for Pembrokeshire homeowners, holiday-let operators, and coastal retreat owners across the county.

At Paving & Slabs Ltd, we supply a full range of composite decking boards with delivery to all Pembrokeshire postcodes, in grey, black, oak, and teak finishes.

Composite Decking Boards Across Pembrokeshire

Tenby & South Pembrokeshire

Tenby is one of Wales's most visited seaside towns, with its medieval walls, colourful harbour, and award-winning beaches creating a unique setting. Properties around Tenby's harbour and headland face direct Atlantic and Bristol Channel exposure. Composite decking boards are popular throughout Tenby and the surrounding South Pembrokeshire coast — from Manorbier and Barafundle Bay to Freshwater East and Lydstep — for both residential and holiday-let gardens where low maintenance and long-term durability are priorities.

Haverfordwest

Haverfordwest is Pembrokeshire's county town, sitting inland on the Western Cleddau river. While more sheltered than the coast, Haverfordwest still experiences Pembrokeshire's characteristically high rainfall and wet winters. Composite decking boards are popular here for the town's mix of Victorian townhouses, newer estates, and rural properties in the surrounding Daugleddau Estuary area.

St Davids & the North Pembrokeshire Coast

St Davids — Britain's smallest city — sits on a wind-scoured peninsula at the very tip of the Pembrokeshire coast, fully exposed to south-westerly Atlantic storms. This is one of the most challenging outdoor environments in Wales. Composite decking boards are the only sensible choice for garden decks and terraces in St Davids and the surrounding north Pembrokeshire coast from Fishguard to Whitesands Bay.

Milford Haven & the Daugleddau Estuary

Milford Haven's deep-water harbour and the Daugleddau Estuary create a tidal, salt-rich waterside environment throughout the inner Pembrokeshire coast. Waterside properties here benefit enormously from composite decking boards' resistance to tidal salt air, humidity, and the particular challenges of building decks close to open water.

Saundersfoot, Narberth & East Pembrokeshire

Saundersfoot's harbour village setting and Narberth's popular market town character attract a mix of permanent residents and holiday visitors. Composite decking is popular across this part of the county for both residential garden decks and holiday-let outdoor spaces. The oak and teak finishes are particularly well suited to the traditional character of East Pembrokeshire's villages.

Installation in Pembrokeshire

DIY Installation

Our 10 tips for installing composite decking and guide to laying decking on soil cover the full process. For exposed Pembrokeshire locations, pay particular attention to subframe anchoring — coastal wind uplift can be significant on unsecured joist frames.

Subframe, Wind Anchoring & Drainage

Use C16-grade treated timber or aluminium joists at 400mm centres. In Pembrokeshire's exposed coastal positions, anchor the frame securely to prevent wind uplift. Build a minimum 1:80 fall for drainage and ensure clear airflow beneath the deck. Finish all board ends with our composite decking corner trim to seal against wind-driven rain and salt spray.

Ongoing Care

Brush off debris and wash occasionally. Guides: cleaning composite decking, preventing fading, removing rust stains, and removing scratches.

Composite Decking vs Paving in Pembrokeshire

For sloped Pembrokeshire gardens and coastal terraces, composite decking often outperforms paving on practicality — a raised deck spans uneven ground far more efficiently than excavated flat paving.
