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. |
