Ventilated subfloor system
WHAT ELSE supplies and installs ventilated adjustable subfloor systems in Latvia – dry build-ups with a void for moisture, emissions, and radon management under the floor.
Discuss a projectWhy ventilation under the floor matters
Moisture in slabs, residual construction damp, VOC emissions from older materials, and radon risk in certain Latvian ground conditions can all make a sealed floor build-up the wrong answer. A ventilated void under an adjustable subfloor gives air a path to move and be managed instead of trapping problems under finishes.
WHAT ELSE supplies and installs ventilated adjustable floor systems as part of dry renovation and new-build packages. Supports and boards create a services and air void; detailing at edges and outlets connects that void to a designed ventilation strategy rather than leaving random gaps.
Dry installation means the floor package itself does not add large volumes of water to an already damp context. Combined with survey of slab moisture and a clear ventilation plan, the approach suits basements converting to occupied use, ground-floor retail, and renovations over older concrete with uncertain history.
We hold supply and install under one contract so moisture detailing, acoustic damping where required, and finish floor levels stay coordinated – ventilation cannot be an afterthought sketched after boards are already down.
Moisture, emissions, and radon voids
The void under ventilated systems is sized and detailed for airflow. Intake and extract paths, firestopping where required, and protection against debris blocking the cavity are planned with the building’s MEP and fire strategy – not improvised on the last day.
For moisture, ventilation helps carry away vapour that would otherwise condense or soften adhesives under impermeable finishes. For emissions, moving air under the floor can support strategies that reduce concentration of residual compounds before they enter occupied rooms through cracks.
Where radon risk is part of the brief, a ventilated subfloor void can form one layer of a wider ground-gas strategy designed by the project’s specialists. WHAT ELSE installs the floor system and void interfaces; radon design responsibility stays with the appointed designer, and we execute the floor package that supports that design.
Damping elements can still be included when impact sound control is required alongside ventilation. The acoustic break and the airflow path must be detailed together so one goal does not cancel the other.
Delivery on renovation and new-build sites
Typical projects include ground-floor apartments, schools with older slabs, hotels converting cellars, and commercial spaces where a wet screed would trap damp. We survey levels, moisture indicators, and planned ventilation connections before proposing a configuration.
On site WHAT ELSE sets adjustable supports, installs boards with the agreed edge and outlet details, and inspects the void before finishes close access. Clients receive a dry, level floor ready for the approved covering and a cavity that matches the ventilation intent.
Documentation can include product data, environmentally declared material sheets where available, and as-built notes for void height and outlet positions when the project requires them for handover or public inspection.
Share slab condition notes, any radon or moisture reports, and target finished floor level. WHAT ELSE will confirm a ventilated configuration and deliver supply plus install in Latvia under one accountable team.
FAQ
- What problems does a ventilated subfloor address?
- It supports management of moisture, residual emissions, and – as part of a wider design – radon, by keeping a designed airflow path under the dry floor build-up.
- Is the ventilated system a wet or dry installation?
- Dry installation with adjustable supports and boards. Ventilation detailing connects the void to the building strategy without adding a traditional wet screed under the whole floor.
- Does WHAT ELSE design radon systems?
- We supply and install the ventilated floor package and void interfaces. Overall radon or ground-gas design remains with the project’s appointed specialists; we execute the floor system that supports that design.
