Basement Wall Membrane – An Important Aspect of Exterior Waterproofing
If you have researched exterior basement waterproofing, you may have learned that a basement wall membrane is an integral part of a typical exterior system. Depending on the specific water problem and where the water is coming from, exterior basement waterproofing may be the best bet to solve your water intrusion problem. All basements eventually need to have the exterior basement waterproofing re done. The original seal will break down allowing dampness to wick into the foundation and eventually lead to water seepage problems through the basement walls. If this is the case, a basement wall membrane can be utilized as part of the waterproofing system. Lets talk about what a basement wall membrane is exactly, what it does, and why it is beneficial for exterior waterproofing.
What is a Basement Wall Membrane?
It is a waterproof barrier that is applied to the outside of the basement wall below grade. The membrane serves the important purpose of blocking water from the foundation wall and preventing any kind of water or moisture intrusion. At Pioneer, we use DELTA-MS. The following information regarding DELTA-MS can be found on the manufacturer’s website:
The vacuum-formed dimpled pattern creates an air gap between the membrane and the foundation for an absolutely dry foundation. 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.
Made from three layers there is a 60% recycled layer sandwiched between two 40% virgin layers. The co-extrusion process and offset dimples of DELTA®-MS create higher compressive strength and impact resistance than other dimpled membranes ensuring its performance and protection lasts. The non biodegradable membrane is superior compared to other membranes typically made from 100% recycled materials and sprays that will break down in the soil.
Benefits of Basement Wall Membrane in an Exterior Waterproofing System
Installing a membrane over top the waterproof coating (which is either sprayed, brushed or rolled onto the foundation first) protects your foundation from moisture and from the backfill process.
Unlike coatings which can biodegrade, corrode or peel with time, the DELTA-MS basement membrane is permanent and has no reactions to moisture.
How is it Installed?
We follow several basic steps:
- Excavate around the outside of the foundation
- Clean walls and repair any cracks.
- Apply a sealant coating.
- Hang dimpled membrane.
- Install footer drains then cover with gravel.
- Backfill to the top with fresh soil.
