Basements built with NUDURA insulated concrete forms provide comfortable living space for homeowners.  Holdfast stocks two waterproofing solutions to keep your basements dry in any kind of weather.  Both DELTA-MS and NUDURA's waterproofing systems provide reliable, cost effective solutions for your basements.



Protecting your foundations from water and moisture is critical. DELTA®-MS is a dimpled membrane that uses exclusive Air-gap Technology to ensure your basements stay dry and last longer. The vacuum-formed dimpled pattern creates an air gap between the membrane and the foundation, allowing water to drain. By keeping water away from the foundation wall, DELTA®-MS is able to keep basements permanently dry and protected. Unlike sprays, which crack when concrete walls crack, it bridges cracks so no water intrusions can occur. This dampproofing helps ensure more comfortable and healthier living spaces for homeowners.
