Do you need a Drainage System from Inside?


An indoor drainage system is required when a basement foundation suffers hydrostatic pressure on the exterior foundation walls due to a high water table. The most common signs of a high water table and  Underdeck drainage systems is water seepage where the floor and foundation wall joins, leaks, soil cracks, and leaks or moisture in the bottom of a foundation wall or foundation cracks.

What are the causes of a high water level around the foundations?

  • Broken /missing/clogged French drain around the outer perimeter of the foundation
  • Poor drainage of surface water (to the house instead of away from home)
  • Excessive water around the foundation due to poor drainage of the cover


It is difficult to identify the particular cause for the rise in the water table since the problem arises in the outer side of the foundation wall or under the foundation soil, an area that is not visible.

How does a drainage system work from the inside?

The interior drainage system is installed along the inside perimeter of the base, Underdeck drainage systems approximately one foot deep and is located next to the foundation footing. From this, water is pushed into the subsoil by hydrostatic pressure. The system intercepts the water before it enters the basement and directs it under your concrete floor to a 4 “PVC perforated pipe at a sump pump. The pump empties the water to the existing sewer or outside.

Agricultural drainage

It improves the soil structure and enables the soil to cultivate in better conditions. The several advantages of land productivity are:

  • Develop a better root system of plants
  • Better assimilation of fertilizers by plants
  • Seed earlier in the spring
  • Harvest in good conditions and improve the efficiency of the machines
  • Better soil conservation
  • Increased yield of crops from 24 to 76%
  • Extension of the growing season
  • Plants of higher quality
  • The positive effect of breeding
  • Return on investment.

Agricultural drainage must be considered as essential capital expenditure to reduce risk. It offers benefits from tax management. Installation costs are fully deductible during the current tax year.

An interior drainage system is installed inside the perimeter of your foundation wall as follows:

  • Part of the surface, about 1 ‘wide, around the perimeter of the foundation is removed.
  • A slice about 12 inches wide and 12 to 18 inches deep is created.
