SELECTION PRINCIPLES

What determines the right system

Site-applied waterproofing layers for defined substrates

Exposed or covered service

A membrane under tile and an exposed roof finish have different demands. State sunlight, traffic, ponding and any intended protective or decorative layer.

Movement and details

Corners, drains, joints and penetrations are part of the waterproofing system. Define movement and reinforcement needs rather than treating the flat surface alone.

Substrate and application conditions

Check surface strength, moisture and existing layers. Weather, drying conditions and access for consecutive coats affect application planning.

USE & EXPOSURE

Application requirements

Identify the defect and water path before choosing a treatment. Substrate repairs, movement details and the waterproofing layer need to work together.

01

Roof and terrace waterproofing

02

Wet-area substrate waterproofing

03

Renovation of compatible waterproofing surfaces

Application areas describe the selection scope. Suitability is determined for the specific material and actual operating conditions.

PURCHASING BRIEF

Prepare your enquiry

Include the following details with your quantity, destination and packaging requirements. A project specification or required test method helps define the material assessment.

Discuss your requirements ↗
  1. Roof, wet area or other application
  2. Substrate, moisture and existing layers
  3. Movement, drainage and standing water
  4. Exposed or covered finish

Questions before selection

Are all liquid waterproofing coatings flexible?

No. Flexibility and movement capability depend on the system. Specify the required movement and service exposure when selecting materials.

Can it be applied over any old waterproof layer?

Existing layers need checks for adhesion, contamination and compatibility. Unsound areas require preparation or removal before recoating.
