Problems with Liverpool Drainage

If your basement, ground floor or garage is wet or your yard or garden is periodically flooded you have most likely got a drainage problem. Depending on the type of problem, either surface water or sub-surface water, depends on the way you handle it. In some instances both surface and subsurface water drainage systems will be required in order to fix the issue.

 

Surface Water

 

Every property should have a sufficient provisions that provide control of surface water runoff from roofs and exposed surfaces. A good landscaped garden with mature shrubs, plants and trees can influence the drainage direction and patterns. If a house is constructed on an incline, even a slight one, the higher side of the property should have a swale (drainage waterway) that directs the water around the side of the house. The drainage swale needs to be at least 3 metres  (10 ft) from the outside walls of the house and the slope of the swale must have a sufficient gradient to convey the collected water away from the property and into a proper drainage outlet, such as an outside water drain.

Subsurface Water

 

Subsurface drainage systems are normally constructed / perforated, corrugated plastic pipes or tube that are at least 10cm (4 inches) in diameter. The pipes are installed underground surrounded by sand or gravel and have at least 2 feet of cover. The excess water is then drained through these pipes. The underground pipe drain any excess water from the garden, yard or foundations into drainage sewers. It is always good practice to have subsurface drains installed at a property. By installing good downspouts to control any roof water can be used to prevent puddle and pools. The downspouts can run into subsurface drains or outlet spreaders that are designed to discharge the unwated water in a layer of grass or soil away from the house’s foundations.

 

Seasonal High Water

 

A water table, or groundwater table, is the upper surface of water in the ground where the soil or surface material is fully saturated with water. The water table level can fluctuate over 12 months by up to a few feet depending on the season and the landscape, the type of soil and the weather conditions.

 

Wet Basements & Underground Floors

 

Water normally enters a basement or underground level via the walls or through the joint between the wall and the floor. If water is coming in through the wall there is possibly a crack or hole in the render (exterior coat of mortar) or the waterproof seal. Sometimes the render or seal can be too thin or non-existent or even the footer drains can be inadequate or missing. The first thing that needs to be done is to make sure the exterior Liverpool drainage is operating sufficiently to take the excess water away from the property walls. To check the exterior wall needs to be exposed where the majority of the water inside is coming in. Small repairs can be made to the rendering however if the problem persists professional help will be needed. If water is entering via the wall and floor joint, your property may not have any footer drains or they could be blocked or not working properly. In the majority of cases, the outside walls may require some excavation work going down to the level of the footer and having a functioning drain added. Good control of outside water all around the property and beneath is essential. In addition to the actual water, poor drainage can result in unwanted fungus, mildew, moss and weeds. When external water saturate or even floods the areas under and adjacent to the house it can cause the insulation to become wet and damaged.

There are certain techniques that can reduce the likely hood of external water problems:

  • A well planned landscaped garden
  • A good functioning external drainage system
  • Properly fitted and maintained gutters and drains
  • A solid, well formed external wall render
  • A waterproof seal in the external wall joints
  • A waterproof foundation wall with quality installed footer drains
  • Well maintained internal drainage pipes
