Using Crack Injection to Fix Basement Water Leaks. Concrete cracks cause water leaks down basement interior walls – Melbourne.
Below ground car parks & basements are at risk of water leaks from ground water or seepage after rain. Negative Waterproofing.
Basement Waterproofing from the Inside
If concrete cracks are left, water leaks will penetrate the concrete surface causing long term damage to concrete roof, walls and floors.
Waterproofing Shotcrete Basement Walls
This is a case study I’d like to share with you which involves waterproofing below-ground basements and using crack injection to repair concrete cracks.
Shotcrete Wall Design
This is a fairly new commercial construction – just a couple of years old. The basement design is the conventional situation of a wet basement with shotcrete walls – pier & beam construction.
The below ground basement was dug-down and excavated out and then Concrete Shotcrete afterwards to create the basement wall surface.
Waterproofing Concrete Walls
The first slide shows the water migrating out from underneath the car ramp down into the below ground carpark from street-level.
Water leaks are actually coming out from underneath the concrete car ramp and the ground slab.
The basement wall design is pier & beam construction with the capping beam at the top.
Water leaks are actually migrating from the capping beam and down the face of the shotcrete basement wall. This is a dangerous situation as water is getting into the exit sign and also all over the copper piping.
Water Leaks & Basement Walls
With ground water seepage in basements there is an immense amount of salts may affect concrete walls, floors, ceilings &fittings. The salts are highly destructive, particularly to copper pipes, and galvanized, and zinc alum fittings. Water leaking causes deterioration very, very rapidly and also cause immense rust.
These safety issues mean that basement water leaks require immediate and expert waterproofing solutions.
Basement Concrete Crack Repairs
There are a number of images demonstrating concrete cracks involving water leaks down the surface of the basement wall.
Basement Waterproofing System
How to Fix a Leaky Basement Wall -The method we used to rectify these below groundwater leaks was using Polyurethane Crack Injection.
Using Concrete Crack Injection – high pressure polyurethane resin which reacts with the water.
Water Reactive Polyurethane Injection – foams up and expands up to ten times its size.
Some of these images show the crack injection foaming reaction taking place – this foaming is actually a good reaction.
The water reactive resin foams, and basically bubbles out, sealing the concrete cracks as it comes out.
Concrete Crack Repairs – we try to get in behind the shotcrete wall and seal the water from coming into the basement walls from behind.
