A Guide To Basement Waterproofing Methods
The basement of a building is by far the area most susceptible to moisture problems and will always require damp proofing measures, particularly in London’s wet climate. The following are some of the best basement waterproofing methods to consider for your new or existing structure!
Interior Sealants – This simple method involves the application of a sealant to the basement’s interior walls and floors. Water seeps into a basement through tiny gaps and cracks as well as porous concrete, especially where the groundwater is high and there is poor drainage. This seepage will lead to harmful mould and mildew growth and water damage if left unchecked, as well as causing harm to the foundation that can compromise the building’s structural integrity. Interior sealants create a waterproof barrier on surfaces to prevent water from entering.
Exterior Waterproofing – Water infiltration from the outside of the foundation walls can be halted by exterior basement waterproofing. The process requires excavation around the foundation’s exterior in order to apply a waterproof coating or a membrane to the wall’s outside surfaces. This is a highly effective solution for water damage prevention and the preservation of the building’s structural integrity, but it is disruptive to install as excavation around the foundation is necessary, and will involve repairs to the landscaping once the work has been completed. It may be worth the trouble though, because it is the most reliable and long-lasting method for preventing water from entering the basement.
Interior Waterproofing – This type of basement waterproofing is an excellent condensation solution when that is the main source of dampness. Interior basement waterproofing directs the water entering through the walls or floor into a drainage course from which it is pumped out by a sump pump and sent away from the foundation. The drainage pipe installed below the basement floor slopes downward toward the sump pump, which is placed in a pit at the basement’s lowest point. The sump pump automatically switches on when the pit’s water level reaches a certain point and pumps the water out of the basement.
Foundation Crack Injections – This method involves the repair of cracks in the foundation walls from the inside, so no excavation of the soil around the foundation is necessary. A liquid polyurethane or epoxy is injected into the cracks, which quickly hardens to form a waterproof barrier that can prevent moisture from seeping in. This method works best on smaller cracks that don’t threaten the structure. One must bear in mind, however, that crack fillers don’t address the crack’s underlying causes, and additional waterproofing measures may be required. This method is unsuitable for large cracks, which will probably require extensive repairs to be made.
