Interior Basement Waterproofing (

Waterproofing basement walls from inside is the best waterproofing solution when: there is excessive moisture in the soil especially under basement concrete slab, or when the basement is very deep, or when neighbours property is located very nearby. To perform foundation waterproofing from the inside, the basement wall has to be exposed, and the floor excavated along the foundation walls for new weeping tile pipe to be installed. We are using Delta MS drainage membrane to direct water to new filtered plastic weeping tile pipe. The advantage of internal waterproofing is that it is not only protecting the basement from water coming through the foundation wall, but also from collecting the ground water from under the concrete slab.

  1. I would be fired if i trenched the footing and it was taking that long with a mini spade? where the hell is your pick? What are you doing?

  2. Isn't the water still coming through the foundation wall though? It still has hydrostatic pressure on the exterior of foundation which will lead to cracks in the foundation wall. But if you were able to put this on the exterior of the foundation wall then it would work better?

  3. Very clever looking up your drainage system to the storm sewer, but just assuming that that storm sewer line is in good shape, to the next step and actually checked the pipe to make sure that there was no breaks or clogs. If you had not done this the system probably would have not worked. Nice job.

  4.   Water is always present… moisture is everywhere, it is running underneath every piece of concrete.  Every hear of hydrostatic pressure.  The secret to basement waterproofing… and to concrete.. is the keep the water moving away from your foundation.  Exterior membranes only move water to a different location of your home/foundation……. like putting perfume on a pig….there is plenty of airflow around the interior membrane… notice all the dimples… it moves water to where you want and allows the wet wall to dry out.  WATER WILL ALWAYS FIND A WAY IN!  I have removed basement floors, driveways, sidewalk, garage floors and find huge caverns underneath them…. sand bases…. torrents of water flow….. 

  5. installing weeping tile in the inside perimeter is not a bad investment if is DIY but is a lot of money if contracted some companies. THE ONLY WAY TO HAVE A DRY BASEMENT IS TO WATERPROOF FROM OUTSIDE THE FOUNDATIONS. CHECK ON OTHER VIDS

  6. in some cases the building or dwelling can not be excavated outwardly and its a practice to install weeping tile on the inside under the slab near the footing

  7. ProgFan67 is right! Platon or any other waterproofing membrane should be installed on exteriors. weeping tile is located on the exterior side of the footing too. I dont see any point of their job, waist of money.

  8. Isn't the membrane intended for the outside? I don't see any reason to place it inside since any water intrusion would naturally drip down the walls
