Advantages of RAWMAT® HDB » Vs. Liquid Applied Membranes

RAWMAT® HDB is a fundamental breakthrough in barrier technology, and leaves the factory as a complete, functioning system.

The following table explains the advantages of RAWMAT® HDB over Liquid Applied Membranes in more detail.

Liquid Applied Membranes RAWMAT® HDB
Require a smooth cured oversite blinding prior to application. RAWMAT® HDB can be laid directly onto a compacted sub base, often no oversite blinding required.
Cannot be laid in the rain or to damp surfaces. RAWMAT® HDB can be laid in any weather and onto wet concrete or other surfaces.
Difficult to maintain consistency so needs specialist labour. QA of membrane in factory, RAWMAT® HDB can be laid quickly and easily by unskilled labour.
Very time consuming, delays between coats. RAWMAT® HDB is swift and simple to install, forms self sealing overlaps, no welding or tapes required at joint.
Must be protected. In most applications no need for protection boards.
Reliant on correct mixture and application of two parts. Pre-formed sheet membrane, single application with simple installation.
Short shelf life. Natural material - indefinite shelf life & performance.
Not self-healing when punctured. RAWMAT® HDB will self-seal if punctured.
Not robust. RAWMAT® HDB is a very robust material which can withstand the rigours of construction sites.
