THE PROBLEM
The cable trench was allowing water ingress which was identified during a factory expansion. This was highly undesirable give that electricity and water do not mix!
SOLUTION
We proposed the application of a flexible tanking system from Remmers as a suitable solution.
Initially all surfaces were prepared by method of vacuum controlled diamond grinding to remove surface laitance in order to ensure excellent adhesion of the new tanking system.
Following preparation all surfaces were treated with Remmers Kiesol diluted 1:1 with water. On to the matt damp surface Remmers WP Sulfatex Rapid was applied by slurry brush and trowel to resolve visible dampness present.
Once cured a cove detail was installed at the floor/wall intersection as per best tanking practice to isolate this point of most probable movement. This detail was then reinforced with an additional coat of Remmers MB2K incorporating Remmers VF120 Tape for additional strength.
The Remmers MB2K tanking system was then applied in a 3 coats to the required thickness by slurry brush and trowel.
Remmers MB2K is particularly suitable for this application as it Remains flexible once cured, which is always of benefit when tanking concrete substrates as it gives greater chance of any future movement or cracking being accommodated with water ingress.
Remmers MB2K was also particularly well suited to this tanking application as uniquely the material will adhere to plastic pipes. This allowed the tanking system to be dressed into the cable ducts, simplifying this detail which can be challenging when using purely cementitious systems.
