We have systems for use on both the negative and positive sides of the structure, basements, tunnels, shafts, culverts, tanks, sumps etc.
We first make sure that we have stopped any active leaks. Once this has been done we will clean and prepare the substrate to give the best surface profile to take the coating system. We have tanking systems that need primers and systems that need no primer.
If the substrate is too wet to be coated we have special indirect hot air dryers that generate large volumes of clean hot air and quickly dry the substrate to the point where the tanking system can be applied.
On internal surfaces to be coated we install a 45° fillet to all 90 corners using fast set natural cement or epoxy mastic. Once all the preparation has been completed (note, preparation is always the main part of any project and cannot be skimped) the coating system is installed, either spray applied or hand applied depending on the choice of material and the site constraints. After the coating has cured / dried enough to allow access the coated surfaces these are inspected for any holidays/voids/patching, and are then rectified, recoated if needed and the site cleaned down and signed off.
For externally applied tanking this usually involves coordinating with other contractors active on the site. We work with the other contractors, communicate our timings and site needs to enable the tanking to be installed and completed on time with minimal disruption to the site.
