Waterproofing

[bjb_jcb]

Have water coming through cracks in our basement floor (not walls). The sump had water running in to the extent that two pumps were pumping, one was .3 hp and the other was .5 hp. Now down to two .3 hp pumps. Have a waterproof system that was installed in May 1996. Was told that the system would take care of the leaks in the floor. Not the case. This area has received 14 inches of rain in a 5 week period. Would anyone out there have a suggestion on what can be done about water coming through cracks? Does anyone know about a product called SANI-TRED's LRB?

Thanks.

Most times if a perimeter drainage system is install around the full interior basement, water pressure will be relieved from under the slab. However in some cases this may not be enough.

I would recommend a lateral drainage line be installed across the floor an directed to the sump. This should take care of the problem.

If your system was installed by a waterproofing company their warranty may cover this leakage. I would recommend contacting them first.
