In new construction, cast-in-place concrete foundations are more resistant to water penetration than concrete block. Bituminous waterproofing should be used, at a minimum, to seal the outside of any foundation wall, however. An effective perimeter drain system should be installed to collect water from around the foundation and under the slab.
The National Association of Home Builder's booklet on dry basements entitled, "Basement Water Leakage - Causes, Prevention, and Correction," recommends perimeter drains on the inside and outside of the foundation. These drains should either flow downward to a gravity outlet (natural drainage) or to a sump where the water can be discharged with a sump pump.
A building built in a wet site should take advantage of additional waterproofing; a membrane system. One example of a membrane system consists of multiple layers of impervious material applied in a hot tar mopped system to the outside of the foundation. Special attention should be paid to the joint between the wall and the footing. The concrete floor and walls (whether block or concrete) should be reinforced to minimize cracking.
