Short Summary

The building manager requested a superior performing waterproofing system to be applied on to the rooftop. The
requirement was for a strong UV stable and highly resistant to foot traffic waterproofing system.

Challenge

SYSTEM RECOMMENDED After consultation with the Durotech team the following system was recommended:

1. WB Epoxy primer and moisture barrier (Two component water based epoxy coating used to prime/seal and coat concrete or masonry surfaces).

2. Duroseal 25 FC polyurethane sealant (A single component moisture curing polyurethane construction sealant which is a tough, durable PU sealant with good chemical resistance.

3. Duroproof PPM/SL polyurethane (A high quality superior performing self-levelling membrane that cures rapidly to form a polyurea/ polyurethane hybrid membrane.

4. - Duroproof ATC UV trafficable topcoat (Is a single pack aliphatic polyurethane topcoat providing greater UV protection, colour fastness and anti-chalking properties.)

Solution

It was applied by brush and squeegee. Due to the Self-levelling abilities of the membrane a squeegee was efficiently used to cover larger areas quickly whilst providing a mirror image.

Outcome

The self-levelling trafficable UV stable polyurethane waterproofing system produced over and beyond the outcome which was required by the manager.

They were impressed not only by the qualities of the membrane such as durability and UV stability but also by the overall image of the rooftop.

A smooth mirror like image was achieved giving it a superior look.
