Exterior Solutions Ltd is a trusted UK supplier of premium decking materials and accessories, offering one of the most comprehensive ranges of deck building supports available — from UV-resistant adjustable decking pads and fixed height timber decking supports through to self-levelling pedestals, joist cradles, rubber shims and the versatile Mega Balance pedestal system capable of heights from 25mm to 1025mm.
Deck Building Supports — A Complete Range for Every Application
Whether you’re creating a rooftop terrace, a ground-level garden deck, a balcony installation or a commercial outdoor space, the right deck building supports are fundamental to a successful, long-lasting result. At Exterior Solutions, we stock a comprehensive selection of support systems designed to meet the full spectrum of project requirements — from straightforward residential decking builds through to complex commercial installations on sloping roof decks with strict waterproofing membrane considerations.
Our adjustable decking support pads are UV-resistant and available across a wide range of height dimensions, raising the deck structure to create a ventilated void beneath that protects joists from standing water and prevents damage to waterproofing membranes.
Our adjustable timber decking pads are placed 600mm apart and accommodate falls in the roof deck, with joist bearers slotted between joist holders at 40mm, 60mm or 90mm spacings depending on your specification. The entire system is completely free-standing — no mechanical fixing to the membrane is required, no bonding, and no risk of movement from the headpiece — making installation clean, straightforward and membrane-safe on any project.

Deck Building Supports — Specialist Products for Every Height and Load Requirement
One of the great strengths of the Exterior Solutions deck building support range is the sheer variety of products available to suit different height constraints, load requirements and installation conditions. For projects with very restricted height thresholds — particularly common on refurbishment projects where limited clearance exists — our adjustable levelling joist cradles provide support from just 10mm to 40mm, raising joists clear of the base to allow water to drain freely beneath while keeping the overall build-up height to a minimum.
For projects requiring greater height range and maximum flexibility, the Mega Balance self-levelling pedestal system is our most versatile deck building support solution — with an outstanding height range from 25mm all the way to 1025mm and a weight tolerance of up to 800kg, making it equally suited to residential decking, commercial paving and integrated rail systems.
Rubber shims — available in 2mm and 3mm thicknesses — complete the toolkit, acting as effective vibration and sound deadening layers beneath slabs, tiles or timber decking and allowing installers to make up small differences in level with ease. Every product in our range is designed to work together as a cohesive system, and our technical team is always on hand to advise on the right combination for your specific project.
