01 · Project overview
What is this project?
Shopping Centre Roof Waterproofing in Portugal, 30,000 square metres in 2024. Portugal. The products on the job are Impermax Polyurea H Flex ALUM. Portugal is the setting, and the exposure is what chooses the build-up.
Project case study Shopping Centre Roof Waterproofing in Portugal Shopping centre roof waterproofing in Portugal renewed the old asphalt roof at Ferrara Plaza, Paços de Ferreira.
Then they hot-sprayed Impermax Polyurea H Flex Alum across about 30,000 m².
02 · Challenge What was the challenge on this shopping centre roof? The roof already carried an old asphalt membrane.
Krypton Chemical supplies the resin system. The duty is ordinary and strict: keep water, wear and weather on the right side of the structure, and do it in the details as well as in the open field.

02 · The challenge
What did this structure ask of the system?
A roof is a field of outlets, laps and edges, and the weather works on all of them. Water does not leak through the middle of a sound bay. It gets in where the detail was thin or where the deck has started to move.
Shopping Centre Roof Waterproofing in Portugal has to be closed as one system, details first, and then left to do its job without a second visit every summer. Across 30,000 square metres, a thin spot is not a small repair.
03 · The solution
Which system was trusted here?
The system trusted here is the one named for the job: Impermax Polyurea H Flex ALUM. It is chosen because it matches the substrate and the exposure, not because every building wants the same can.
On a roof the membrane has to follow outlets and upstands at the same thickness as the field. An exposed aromatic film takes a topcoat if the colour will be seen.
04 · Application
How is the system built?
The products named for Shopping Centre Roof Waterproofing in Portugal are applied as one build-up, details before the field. Outlets, edges and changes of plane are closed first, with the same materials as the main area. A system that changes product at the difficult line is a system with a future peel.
The line is Impermax Polyurea H Flex ALUM. The deck is dry, the temperature is inside the range that product allows, and the next coat follows while the window is open. Leaving a detail for the following week is how these jobs come back.
On Shopping Centre Roof Waterproofing in Portugal the roof fails at the edge long before it fails in the field. Parapets, outlets, plant plinths and laps are detailed first, with the same system, at the same thickness. A bay can be perfect and the ceiling still stains if the outlet was a collar of mastic.
The deck moves between the hot afternoon and the night. The membrane has to move with it. A rigid coat maps every crack in the substrate onto the ceiling. Thermal movement is the reason an elastic system is on a roof like this, not a preference for a particular can.
Where the film stays in the sun, colour and waterproofing are two layers. The membrane keeps the water out. An aliphatic coat keeps the appearance. Skipping the topcoat because the membrane is already waterproof is how a sound roof starts to look failed, and then gets recoated for the wrong reason.
05 · Results
What does a job like this stand behind?
Shopping Centre Roof Waterproofing in Portugal has one standard. The coating is still doing its job after the building is back in use, at the details as well as in the middle. The area on this job is 30,000 square metres.
Figures for cure, thickness and strength, where they are given, come from the product data sheets. They are not a test cut out of this building.
What this asks of Shopping Centre Roof Waterproofing in Portugal is workmanship at the difficult line. The open field is the easy part of a resin job. Outlets, edges, penetrations and changes of plane are where thickness goes missing, and where water or wear finds the gap. The same products and the same care belong there, and the cure is allowed to finish before the building goes back into use. That is the difference between a coating that was simply applied and a system that stays in service.
