Construction FAQ: answers from Project For Building’s technical team

Whether it involves a ventilated crawl space, a lightweight bidirectional slab, permeable paving or a below-ground wall protection system, every construction project requires specific technical assessments.
Every day, designers, construction companies and distributors face questions about choosing the most suitable system, sizing, installation and the performance of different products.
Having clear, reliable answers means making more informed design decisions and approaching construction work with greater confidence.
Which solution is most suitable? How does the build-up change? What are the differences between two systems? How do you choose the right product for a specific project?
These are questions our technical team addresses every day alongside industry professionals.
That is why we have decided to bring together the most frequently asked questions and answers in a new section dedicated to Construction FAQs, providing technical support that is always available and easy to access.

FAQs organised by application area in construction
Our Construction FAQ section does not replace the design support provided by our technical team, but serves as a first point of reference for understanding the features, performance and application methods of our systems.
The FAQs are divided into Project For Building’s main construction application areas:
- ventilated crawl spaces
- lightweight bidirectional slabs
- driveable permeable paving
- mechanical protection for below-ground walls
- dimpled membranes for the protection of below-ground structures
Each section brings together the most frequently asked questions arising from practical experience on site, organised to make it easier to find relevant information quickly.
Some of the topics you can explore
In the new FAQ section, you will find answers to questions such as:
Why install a ventilated crawl space?
What loads can a ventilated crawl space support?
What is the difference between SUB PRO and SUB ONE?
How do you choose the height of a lightweight slab?
Is GREEN PARKING suitable for vehicle traffic?
What is the correct build-up for permeable paving?
What is the difference between SKUDO and a dimpled membrane?
When should SAFE ROLL be used?
Each answer has been developed by our technical team, with contributions from our Technical Sales Engineer Alessandro Lavelli, based on the enquiries we receive every day during the design process and while providing technical support on construction sites.
Our goal is to make our technical expertise available to help you make informed decisions and organise your work more effectively.
Beyond the product: technical support throughout the project
Alongside our products, at Project we provide expertise, documentation, support tools and design consultancy to help professionals identify the most suitable solution for their specific application requirements.
The new FAQ section on our website is part of this approach: sharing useful knowledge, drawing on the experience of our technical team and providing a quick, regularly updated reference resource.
