About waterproofing
Waterproofing is the work of keeping water on the outside of a building. It matters most at the places where one material meets another: where a roof meets a parapet, where a wall meets the ground, where a balcony meets a door threshold. Those junctions are where most water gets in, and they are where this work is concentrated.

Each one has its own page explaining the warning signs, the work involved and what changes the scope.
Exterior Wall Waterproofing
Treating walls that have started absorbing water instead of shedding it, without sealing moisture inside.
Foundation Waterproofing
Keeping ground water out of a foundation wall, ideally from the outside where the pressure is.
Below Grade and Basement Waterproofing
Making a basement usable and dry, using exclusion or managed drainage depending on what access allows.
Parapet Waterproofing
Sealing the wall that stands above the roofline, which is exposed on every side and fails first.
Balcony and Terrace Waterproofing
Waterproofing outdoor floors that sit over occupied rooms, where the door threshold is the weak point.
Crack Injection
Filling a leaking crack through its full depth with resin, once the movement behind it is understood.
Drainage Systems
Getting water away from a building, which is usually cheaper and more effective than sealing it out.
Moisture Remediation
Putting right what water has already damaged, once the source has been stopped.

Questions
What owners ask about waterproofing.
Why does water keep coming back after a repair?
Usually because the visible damp is not where the water enters. Water tracks along beams, behind renders and down cavities before it appears. Sealing the stain rather than the entry point is the most common reason a repair does not hold.
Can waterproofing be done from inside?
Sometimes, and crack injection and internal tanking both have their place. But water pushing from outside is best stopped outside wherever access allows, because internal work holds the water in the structure rather than off it.
Does new waterproofing need the drainage fixed first?
Almost always. A coating over a surface that holds standing water will fail early. Correcting falls and clearing outlets comes before anything new goes down.
How long does waterproofing last?
It depends on the system, the substrate and the exposure. What shortens it most is applying it over a damp or unprepared surface, which is why preparation takes up so much of the programme.
