MCS_012 3.0 CertifiedSolVe MountSolar Mounting for Cambrian interlocking slate roofs
Fire Safety compliant roof mounting. Airtight VMQ seal, no open air void in the roof — the fire rating is preserved. MCS 012 3.0 certified.

Installation Difficulty
A team of two can install 4 SolVe Mounts on a Cambrian Slate roof in less than 2 minutes.
NHS, Hampshire. Cambrian Interlocking Tiles - 930 roof mounts
Cambrian Interlocking Slates cannot use flashing as they are nailed together, preventing the installer from being able to slide flashing underneath or remove without damaging the tiles.
Before using SolVe Mounts, the NHS project in the video were looking at removing up to 6 Cambrian tiles per mounting, each tile taking 5+ minutes to remove. Traditional roof hooks & flashing on Cambrian Interlocking Slates would require tile removal - dramatically increasing the cost of labour, caused unexpected delays and damaged a lot of tiles.
Key benefit for Cambrian slate
No sealant, flashing or tile removal required. Simply tightening a nut creates an IPX8 rated seal.
Fortunately, they SolVed the problem by using our mounts!

Key Takeaways
- No sealant, flashing or tile removal required — tightening a nut creates an IPX8 rated seal
- MCS_012 3.0 Certified (Certificate BBA 7460) for Cambrian interlocking slate
- No adjustments required - install straight out of the box
- Mounting zone: 0-70mm from overlapping tile edge
- Positioning note: Avoid the join and channel - move left/right of the join
Material Pedigree
The Seal Trusted Where Failure Isn't an Option
When failure means a downed aircraft or a breached reactor, engineers choose VMQ silicone. SolVe Mount uses the same seal material family — proven across six decades in environments that make a British roof look trivial.
Space
International Space Station
Docking port seals and habitat pressure boundaries — where a single failure breaches a pressurised environment in orbit.
Aviation
Boeing · Airbus · Rolls Royce
Pressure cabin door seals, jet engine assemblies, and aircraft fuel systems — maintaining integrity through thousands of flight cycles from −60 °C to over 200 °C.
Nuclear
Power Generation
Containment gaskets in nuclear stations where chemical resistance and zero compression-creep are non-negotiable.
Defence
BAE Systems
Submarine pressure seals, naval vessel systems, and defence electronics requiring long-term environmental resistance.
No sealant, flashing, grinding or removing slate required. Just tighten a nut.
Installing on Cambrian Interlocking Slate
CORE - 28mm diamond core to create your 'working area' to access the rafter.
DRILL - Pre-drill using the drill guide provided.
FIX - Screw in the fully assembled SolVe Mount. If using the all in one install method, the seal will compress as the bolt enters the rafter. Alternatively tighten once installed. For Cambrian slate, no adjustment is typically needed unless the battens require raising the seal height.
DONE - Your MCS certified, IPX8 rated Cambrian slate roof mount is complete.
Making solar installation simple, fast and repeatable. No Cambrian interlocking slate expertise required.
Unshrinkable Technology
Maintains a permanent 34-36mm expansion above and below the roof covering, ensuring no retreat or seal degradation over time.
172-Year Longevity
ASTM D395B testing confirms ~30% compression set after 172 years, preserving elasticity and waterproof "springiness."
Load Isolation
Forces are channeled directly to the rafter. The seal expands radially, exerting pressure only on the core hole walls, not the slate.
Triple-Seal Protection
Primary seal matches roof covering depth, augmented by upper and lower seals for 100% watertight confidence.
