Project design
The waterproofing design, ready to tender and build.
We design your building's waterproofing, zone by zone: drawings per level, construction details, technical specifications and bill of quantities. Orion designs; the works are built by the contractor you award.
Sample · 9 sheets · 16 3D details
The designer is not the installer
When design and execution are in different hands, each answers for its own part. Many developers and owners require it.
Separate responsibilities
If something fails, you know whether it was the design or the execution. It does not all sit with one company.
Comparable bids
With the specifications and bill of quantities, every installer prices the same scope and bids are compared on equal terms.
A solution for each zone
Basements, planters, terraces, bathrooms, roofs and trafficable slabs: each zone with its system and datasheet consumption.
What a project design includes
Drawings per level
One sheet per floor, with every waterproofing zone marked by system.
3D construction details
Junctions, upturns, planters, ramps and special points, drawn layer by layer.
Technical specifications
System, materials, surface preparation and consumption per zone.
Bill of quantities
Items and quantities to tender the works and control what is billed.
Every junction, drawn layer by layer
The 16 details of a sample project. Each one shows the system and the order of the layers, so nothing is left to interpretation on site.

From architectural drawings to a construction-ready design
- 1
You send us the architecture
Plans, sections and the project stage. With that, we quote the design.
- 2
Tender-ready design
Sheets, specifications and bill of quantities so the works can be priced accurately.
- 3
Construction-ready design
The final version, adjusted to the final architecture as the works progress.
