XPS boards and drainage membrane in one renovation
An XPS board is a closed-cell, extruded polystyrene insulation panel: ideal for foundations and plinths alike because it does not absorb water. Paired with it, the drainage membrane channels groundwater away from the wall. If you are planning a foundation renovation, Baupro's building materials business – with more than 30 years of professional experience – supplies both products and the geotextile from a single source, with delivery in 2–7 working days. From this article you will learn how the layer system is built up and what to watch for when ordering.

Personal advice before ordering is available on +36 30 389 2676, delivery takes 2–7 working days, and on-site collection time slots are also available.
How do the XPS board and the drainage membrane work together?
In a renovation, thermal insulation and water drainage are two separate tasks – but only together do they provide a lasting solution:
Layer
Material
Role in the renovation
Wall surface
renovated surface, sealing
the first line against moisture
Insulation
XPS board
reducing thermal bridging, without absorbing water
Drainage
drainage membrane
channelling groundwater away from the wall
Filter layer
geotextile
protecting the drainage membrane from the soil
Backfill
compacted soil
stable protection for the system
The XPS board goes onto the excavated foundation wall, retaining its insulating capacity even in soil moisture. Next comes the dimpled drainage membrane, which guides the water downwards, and finally the geotextile prevents the backfilled soil from clogging the drainage channels. Baupro delivers all three materials from stock, so the project can be put together with a single order.

Frequently asked questions
What is the difference between an XPS board and a drainage membrane?
The XPS board insulates; its closed-cell structure resists moisture. The drainage membrane does not insulate – it channels groundwater away from the wall. In a foundation renovation the two are used together.
Is it enough to fit only XPS boards on the foundation?
XPS on its own insulates, but it does not solve drainage. On wet soil the drainage membrane and the geotextile protect the wall – it is worth planning them together.
How long does it take to receive my order from Baupro?
Baupro typically delivers within 2–7 working days; on-site collection time slots are available on the website.
