Combination
In some cases, it may be necessary to use both a Combination of Injectable & Membrane Waterproofing techniques to provide complete waterproofing protection. For example, if a structure has significant cracks or gaps that require injectable waterproofing, but also has a large surface area that needs to be waterproofed, a combination of both techniques may be used. In such cases, injectable waterproofing would be used to seal the cracks and gaps, while membrane waterproofing would be applied to the larger surface area to create a seamless and comprehensive waterproofing barrier.
Overall, the decision to use both injectable and membrane waterproofing techniques would depend on the specific requirements of the project and the nature and extent of the water ingress problem that needs to be addressed.
