Vault Waterproofing

For waterproofing of vaults we recommend cavity drain membrane systems as they are sympathetic to any movement in the structure.

We do not recommend cementitious systems for vaults as any movement will cause the system to fail. As vaults can be under roads and footpaths there is a chance of movement which will therefore not affect cavity drainage. With difficult ground conditions such as vaults formed in clay we believe a CDM installation is a must.
