Installation of cementitious waterproofing membrane and leak sealing injection of rumpus room
Waterstop Solutions leak sealing and remedial waterproofing specialists recently inspected a rumpus room where there is bare earth on the outside of the wall underneath the house. This creates a high humidity environment for moisture ingress to occur into the rumpus room.
We also inspected the floor/wall joint in the same room, along the area between the cupboard and the window, identified by the client as experiencing water ingress. Floor/wall joints (cove joints) are vulnerable to seepage and a common point of entry for water.
Our remedial waterproofing recommendation:
- To reduce the moisture ingress from outside the wall, we recommend installing a polymer modified cementitious waterproofing membrane in multiple layers over a water-based epoxy primer to the back of the rumpus room wall (positive side).
Our waterproof membrane (NSM 100+) is a two-component acrylic modified cementitious coating that is flexible so that it can handle a small amount of movement.
This membrane is a hardwearing, seamless waterproofing membrane for effective concrete protection. It also provides an effective barrier to waterborne salts and atmospheric gases.
The NSM 100+ system is breathable. Whilst repelling water, it allows moisture to pass through it slowly as a vapour, allowing the substrate to breathe.
It is water-based, so any vapours are non-toxic and ideal for potable water usage and it can be painted over in water-based breathable paints (e.g. low sheen or matt acrylics) and most water-based after-trades such as direct stick, tiles or render.
- Perform leak sealing injection of the floor/wall joints alongside the inside wall of the cupboard to the window.
We do this by intersecting the leaking floor/wall joints in the rumpus room at intervals of approx. 200mm and inject a water-reactive polyurethane resin at high pressure into the targeted areas to form a durable watertight seal that bonds strongly within the concrete.
Our technicians manage the injection process to create a continuous three-dimensional seal buried in the concrete using a combination of proprietary methods, developed and honed over thousands of projects.
After allowing the polyurethane to react and bind with any water present in the crack and surrounding concrete to form a flexible seal, the injection ports are removed and holes filled with a suitable rapid set concrete repair material.
