Tunnel Waterproofing Systems and Membranes

The choice of tunnel waterproofing systems and membranes is reliant on a number of factors

1. The type and construction of the tunnel.
2. Expected exposure to water in the location.
3. Above water table or below
4. Minimization of maintenance costs

Such tunnels through rock or other strata may only have to cope with seepage through the rock. Where there is no hydrostatic pressure present, and ground water level below the tunnel footing. Tunnels waterproofing in such tunnels has waterproofing applied only to the top and sides.

Design and Construction of tunnels are different

• in loose rock.
• Below the water table
• under a river on the ocean floor (eg Sydney Harbour Tunnel), or
• where springs and water streams are found running through the strata.

Tunnel construction conditions, means the tunnel waterproofing membrane requirements are high. It is necessary to fully wrap the tunnel with a continuous waterproofing membrane. In tunnel waterproofing membrane system designs must be able to withstand hydrostatic pressure.

Tunnel Waterproofing Methods

The method of waterproofing is critical selection of the wrong waterproofing approach or worse still incorrect installation of the waterproofing systems has the potential to cause severe damage to the tunnel structure, and increasingly high maintenance and refurbishment costs. The water inflow in tunnels and other building structures is detrimental to longevity of the structure. Water leaks have long been recognized as one of the most important factors of damage to the structures.

Preventing Leakage

Cold joints and penetrations are the most common cause of leakage in any underground structure. The lack of proper detailing and installation of waterstops and flexible joints in the structure causes groundwater infiltration.

#Waterproofingmembrane prevents ingress of #Undergroundwater. This reduces costs of #Longtermmaintenance giving an increased service life of the tunnel structure.
