Frequently Asked Questions

What structures can injectable waterproofing be done on?

Whilst injectable waterproofing can be done on buildings and structures at any time of construction, we find that the main use is remedial works of existing structures. In fact, it’s often recommended for structures that are already showing signs of water damage or leakage. However, it’s important to note that the process may be more complicated and costly for existing structures, as Stop and Seal may need to remove existing materials or make modifications to the structure to properly inject the waterproofing material.

What is injectable waterproofing, and how does it work?
Injectable waterproofing is a method that involves injecting a liquid waterproofing material into cracks or voids in a structure. The material then hardens and forms a water-tight barrier, preventing water from penetrating the surface.
What types of structures can benefit from injectable waterproofing?

Injectable waterproofing can be used on a variety of structures, including concrete walls, foundations, tunnels, and parking structures.

What is the difference between Water Ingress and Water Egress?

The term “water ingress” refers to the process of water entering a space or area, such as a building through an opening or gap. This can cause damage to the structure, equipment or materials within that space.

On the other hand, the term “water egress” refers to the process of water leaving a space or area, usually through a drain or other outlet. This is often necessary to prevent damage or flooding, particularly in areas that are prone to heavy rainfall or flooding.

In short, water ingress is the process of water entering, while water egress is the process of water leaving.
