Common methods of concrete haunching, mechanical links or quick-set cements commonly failed due to the very nature of the construction process.

The DryVault System provides for a custom installed waterproof seal around the pipe
Since 2002 – Mountain Waterproofing has been specified to provide the pipe entry waterproofing system to new chamber installations for the City of Calgary Waterworks.
This system, called the MWP DRYVAULT SYSTEM…
is a method of ensuring a 100% water- tight seal on the chamber. This system actually speeds up the construction time and can save money on the overall project.
