Structural Waterproofing

New Construction

Knowing the importance of the concrete quality in achieving below grade watertight structures, Co-mender developed a full solution to help contractors achieve better durability results in their below grade structures construction. In the Middle East region numbers showed that 80 % of these structures and despite using a sophisticated waterproofing sheet membranes system are still leaking leading to real durability issues in the remaining life of the structures.
In Co-mender and after 20 years of experience with the below grade waterproofing of major concrete structures, we believe that concrete is the second defending line in case of the failure in the external waterproofing sheet system. To achieve a watertight concrete, Co-mender have developed an advanced engineered solution that can reduce the amount of water seepage into the structures and minimize its consequential damages.

Components of Co-mender’s structural waterproofing system:

• Engineering
• Watertight concrete
• Post-tensioning System
• Waterstops
• ComendAIR Technology

Engineering

Co-mender’s engineering experts collaborates with designers and construction firms throughout all stages of design and construction and provides the following services:

Co-mender’s post-tensioning system :

Co-mender and in collaboration with its partner OVM-MENA have developed a special post-tensioning system that can be applied to vertical walls and reduces the amount and width of cracking. Similarly to post-tensioned water-tanks the cracks in basement walls can be better controlled or even eliminated providing better durability and functionality to the basement spaces.

Co-mender’s Joints sealing system

Joints and penetrations are the most critical elements in the below grade waterproofing system. Special attention is needed in the design phase and construction phase to achieve a sealed joints. Co-mender’s joints sealing system is carefully selected for both durability and performance.

ComendAIR Technology

After designing the full waterproofing system and reviewing all its essential components, Co-mender provides its international waterproofing experts live and easy access to the site operations during concrete placement. It’s smart monitoring system and live connectivity with the site team allow the experts to provide their technical advice right on the spot eliminating a lot of possible concrete quality issues at site.
