How long does concrete need to cure before waterproofing?
The curing time for concrete before waterproofing membrane application depends on the waterproofing product being used and varies from 24 hours to 28 days.
Using hydrogel to replace membranes in basement waterproofing
A hydrogel formation can be induced in concrete by means of catalytic water-borne colloidal silicates. The hydrogel completely seals the porosity of the concrete, immobilising the moisture and preventing watermovement into or through the slab.
