When building or buying a newly constructed home ALWAYS insist that contractor use a waterproofing material on the exterior foundation walls. Although these two products may look very similar, they are VERY DIFFERENT in how they perform. Many contractors continue to use dampproofing because once the foundation is backfilled the area is "out of sight, out of mind", and once the house is finished and sold it becomes the homeowner's problem if the foundation starts to leak.

Waterproofing products are designed to "prevent" water penetration even under wet conditions such as hydrostatic pressure in the soil after heavy rain storms or spring thaws. Aquaseal's products contain rubber which provides superior waterproofing protection and allows the product to remain flexible even when it dries. This flexibility allows the waterproofing membrane to stretch as the foundation settles and bridge small hairline settlement cracks that can occur in the concrete or block. See similar questions...

Dave Caves Construction assures proper drainage by correct placement of drainage tile with a granular fill. This tile drainage system is natural "gravity flow", not dependent on electricity supplied to a sump pump. Bentonize wateproofing is also applied. We use Bentonize since it is inorganic and stable underground. It will not deteriorate due to acids in the soil. (Further information on our Bentozine waterproofing available upon request.)

If your home is in an area with well draining soil and you have good quality backfill material, then you can carefully backfill directly against our products. However, if your backfill material contains rocks or stones that could damage the newly applied rubber membrane, then we recommend the use of a product such as our Aqua-Wrap. This 6mil polyethylene sheeting is highly puncture and tear resistant and will prevent rocks from puncturing the waterproofing. See similar questions...

You probably need weep holes OR a foundation drain—not both. Weep holes are cheaper but they are also more visible. If you choose to use weep holes, you need to know that these are not tiny little plastic tubes. They are surprisingly large chunks of PVC pipe—1.5” diameter, minimum. You need to install them at about 6’-0” on center. The tubes should extend about an inch beyond the face of the wall to keep water from drooling down the face of the wall. See similar questions...
