Do you have a wet of damp basement? When there is a big rain fall do you have water streaming across your basement floor?

Common types of water/moisture related issues:

Through a crack in the foundation wall, leaking/seepage at the base block or where the floor meets the wall, or moisture/dampness/ staining towards the tops blocks.

Different Scenarios:

If you experience leaking through a crack in the wall or in the middle sections, it is generally a water “proof” issue where the exterior of the wall is not properly sealed, and water enters through the wall from the exterior.

If there is moisture or staining on the top blocks of the wall, there could be improper exterior pitch or grading. If exterior grade is at a negative pitch towards the home this will cause pooling on the exterior. As water sits on the exterior it slowly soaks into the block and can cause issues.

If leaking, seepage, or staining occurs at the base block or where the floor meets the wall it is a sign of failing interior drain tile. This is when water enters the interior drain tile system and is not draining properly to the sump crock or sewer system. The water will retain within the drain tile system and seek other areas to drain. Many times, it seeps up and retains within the cores of the block walls at the base or underneath the basement slab floor. Eventually the water will make its way on to the basement floor where it is visible.

Is it my drain tile?

Things to look for:
  • Leakage/seepage on floor.
  • Wet/damp wall blocks near floor.
  • Staining/efflorescence on wall blocks near floor.
  • Iron ochre, tree roots, or mineral/calcium deposits in sump crock or at palmer valve.
  • Wetness around floor cracks.

If the home has any of the above, it is a good idea to have us out to perform a drain tile inspection to determine whether drain tile replacement is warranted and if so, how much drain tile needs replacing.


Drain tile inspection


Upon arrival we open around 3 inspection holes around the perimeter in the basement floor to expose inside of drain tile. Visually inspect tile condition to determine degree of obstruction if any, introduce water into hole to determine if it drains to the corresponding inspection hole/sump crock/palmer valve.

If needed, to inspect the exterior drain tile and cross bleeders we drive an exterior water spud in the ground on the exterior alongside the wall. Water is introduced on the exterior, through the spud, to see if water is entering the interior drain tile system properly.

We check functionality of palmer valve or sump crock.
