How to properly install a underslab/blindside waterproofing/vaporproofing membrane
While choosing the correct waterproofing/vaporproofing membrane is important to achieve a successful barrier in any underslab or blindside application, proper installation is imperative to avoid costly and time-consuming repairs if failures occur. W. R. MEADOWS recommends using PRECON pre-applied underslab/blindside waterproofing membrane for vertical and horizontal applications when access to the positive side of the concrete is restricted. Prior to applying PRECON, proper surface preparation is necessary to ensure the surface is structurally sound and all objects are removed that may cause damage to the membrane. Use of MEL-DRAIN is recommended to be used with PRECON to assure proper site…
