The Boston metropolitan area is vibrant and constantly growing. TOWARDEX, an internet infrastructure provider, is involved in a project to establish the nation’s first large-scale innovative system designed to offer extensive network interconnections, utilizing numerous cables linked to Boston’s internet networks. To accommodate these cables, an underground tunnel system has been constructed. The subsequent phase of the project involves ensuring that these vaults, which contain hundreds of cables, remain dry and secure.

Background

TOWARDEX’s existing approach to waterproofing the vaults relied on an insert positioned beneath the cover to collect any infiltrating water. This method was far from ideal and created a safety risk by causing the cover to sit above the frame.

The solution

Given the importance of keeping the utility vault dry, EJ presented the DUOSEAL watertight assembly to achieve a watertight seal on the manhole cover. The DUOSEAL assembly has been tested to EJ Watertight Level 8, meaning it can withstand 3 1/2 atmospheres of pressure (51.45 psi), which is equivalent to approximately 118 feet of water on top of the manhole assembly.

After several rainfalls, the DUOSEAL assemblies were inspected to verify that everything below the vault was staying dry. The customer was astonished and was able to find the solution they’d been looking for in maintaining their most frequently accessed telecom vaults.
