Full-system waterproofing to specification
We do every type of waterproofing — sheet membrane, liquid, torch-on, epoxy, waterstops and joint sealing — installed to the project engineer’s specification. Trade-to-trade today; package-ready for developers tomorrow.
How we’re organised
Management over one connected system
Aquastratum is a company where the work stays under control. Management sits over everything — projects, technologies and people work as one system, each pointing to the others.
How we manage the workWho we work with
Trade & Remedial companies
Your waterproofing subcontractor across all systems. Waterproofing and remedial contractors bring us in on roofs, balconies, planter boxes, basements and tanks — trade-to-trade, reliable, detail-focused.
Developers & Head Contractors
Package contracts covering multiple systems across build stages, installed to the project engineer’s specification. A direction we’re actively building toward.
Why the work qualifies for a warranty
Because a manufacturer-trained crew carries out the installation, the installed system qualifies for the manufacturer’s warranty — something an uncertified installation can’t offer.
Manufacturer-trained installers
Completed installer training for Fatra, ARDEX & Soprema — so the systems we install qualify for the manufacturer’s system warranty.
