Large terrace systems often get the spotlight, but the real performance advantages in rooftop terrace design come from the small, engineered components working behind the scenes. These details determine drainage, stability, wind performance, sequencing efficiency, and long-term durability.
Here are the components that quietly solve big rooftop challenges.
1. PDS-R Rail Paving Drainage Spacer


Problem it solves
Surface water left sitting on paving can lead to algae build-up, staining, ice formation in colder months, and general maintenance issues.
The PDS-R spacer rapidly moves water off the tile surface, mitigating these problems and ensures roof terraces remain visually clean, safe underfoot, and long-lasting.
How it works
The drainage spacer breaks the surface tension of water on the paving tile, allowing surface water to dissipate almost 10x faster than it would naturally.
Its twist-lock base slots securely into the RST Aluminium Paving Support Rail, while the 4mm spacer tabs create consistent joints between tiles.
Available in T, straight, and cross configurations, it integrates seamlessly into any paving layout.
What are the benefits?
- Dissipates up to 97% of surface water in 1 hour*
- Reduces algae growth and staining
- Minimises ice formation during winter
- Creates consistent 4mm paving joints
- Compatible with RST Support Rails (T, straight, and cross layouts)
- Faster installation with a secure twist-lock fit
- Supports long-term surface performance with less maintenance
*In a controlled environment. Weather conditions may vary performance.
2. FBP Fixing Baseplate


Problem it solves
Securing light-duty features, such as bollards, door stops, and fence posts on rooftop terraces has always posed a challenge.
Traditional fixing methods require penetrating the waterproofing membrane, introducing risk, cost, and long-term maintenance issues.
The FBP Baseplate removes this risk entirely. It provides a robust fixing interface that clamps directly to TerraSmart joists, allowing secure installations without breaching the waterproof layer.
How it works
The FBP Baseplate is a patent-pending system designed to create a strong, compliant fixing point within TerraSmart subframes.
Using either a flat aluminium plate or a steel pin base, it anchors light-duty applications by clamping to the joist structure, distributing load evenly and maintaining full membrane protection.
FBP-A – Flat Aluminium Top Plate (300 × 300 × 10mm)
A versatile fixing surface ideal for bollards, door stops, signage, and similar applications.
FBP-S – Steel Pin Baseplate
Designed for fence post installations requiring vertical pin anchoring.
Both options clamp directly to TerraSmart joists to create a strong, reliable fixing point while maintaining waterproofing integrity.
Benefits
- Requires no penetration of the waterproofing membrane
- Fully compatible with the TerraSmart system for seamless integration
- Non-combustible materials
- 1 kN horizontal load capacity
- Optional aluminium spacers for paving applications
- Enables retrofit and reconfiguration, allowing features to be added or moved without disturbing existing waterproofing
- Faster, safer, and more compliant installation compared to traditional fixing methods
3. Wind Uplift Restraint – Hidden Fixing


Problem it solves
Lightweight terrace finishes; especially porcelain are vulnerable to wind uplift on tall buildings or exposed locations.
Traditional uplift restraint solutions can be bulky, visible, or difficult to maintain, compromising both design intent and practicality.
The Rail Wind Uplift Restraint – Hidden Fixing solves this by securing kerfed porcelain tiles discreetly to the RST Aluminium Paving Support Rail, delivering reliable resistance to uplift forces without any visible hardware.
How it works
This specialist stainless-steel component locks the porcelain paver to the rail using a two-washer system and a central machine screw:
- The retained top washer and screw head sit neatly within the kerf of the porcelain tile.
- The bottom washer engages with the RST rail.
- Tightening the screw locks the tile to the rail, creating a hidden but robust restraint.
Its design allows easy access to the screw, meaning tiles can be removed and replaced quickly if damaged.
The blackened stainless-steel finish keeps the fixing almost invisible after installation.
Benefits
- Hidden fixing for a seamless, premium appearance
- Meets UK wind loading requirements
- A bottom washer that drops in anywhere along the rail
- Removal of spacer tabs for faster, more familiar assembly
- A standard-sized screw, now blackened for invisible detailing
- The clip can slide along the tile kerf, making lift-out and tile replacement effortless
- Stainless steel A2, blackened for discreet detailing
- Simplified clean finish for an all round smarter system
4. BaseLink (Our New Component)


Problem it solves:
Balustrades have always been one of the most challenging elements of rooftop design.
Traditionally, they must be mechanically fixed through the waterproofing layer into the building structure, creating a high-risk penetration point that can lead to leaks, complex sequencing, structural coordination issues, and difficult detailing at roof level.
BaseLink eliminates these issues entirely.
It provides the first fully integrated, non-penetrative connection between a raised flooring subframe and a load-bearing balustrade. Instead of treating the balustrade as an isolated element that disrupts waterproofing and workflow, BaseLink makes it part of the engineered terrace system itself, strong, compliant, coordinated, and completely hidden.
The result: no penetrations, no sequencing conflicts, no guesswork. Just a clean, unified system that architects, contractors, and installers can rely on.
What BaseLink does
The BaseLink Balustrade Connection is a patent-pending steel component – zinc-nickel electroplated for extreme durability, that forms a structural link between the TerraSmart rail substructure and the Linear Track Balustrade system.
Here’s what happens:
- The BaseLink unit clamps securely within the TerraSmart raised flooring rail.
- The Linear Balustrade post connects directly to this reinforced interface, creating a hidden, engineered load path.
- No fixings pass through the waterproofing layer – eliminating the need to drill into the building structure.
- The system delivers a tested, reliable performance of up to 1.5kN/m horizontal line load, ensuring full compliance for residential and commercial applications.
The balustrade becomes part of the subframe, not a membrane risk and not a structural complication.
Benefits
- Zero waterproofing penetrations – dramatically reduces long-term leak risk.
- Simplified sequencing – balustrades and terrace finishes can be installed in parallel.
- Cleaner, integrated architectural appearance – no visible fixings or clutter at roof level.
- Improved structural continuity – balustrade loads are transferred intelligently into the substructure.
- Faster on-site installation – fewer trades, less coordination, reduced disruption.
- Greater design flexibility – supports a wide range of balustrade styles and terrace layouts.
- BaseLink is more than a component; it’s a system upgrade that changes how designers approach rooftop safety and terrace integration.
Rooftop Systems That Perform
These components show that rooftop success is rarely about one impressive material; it’s about how every element works together.
When the substructure, support, restraint, drainage and balustrade systems are coordinated, the result is:
- Better performance
- Faster installation
- Higher design flexibility
- Lower long-term maintenance risk
