Exterior waterproofing, also known as external waterproofing, addresses leaky basement issues from the outside of your home. This method involves exposing the foundation walls and applying the necessary waterproofing materials to create a robust foundation waterproofing system. It is the most popular and effective solution offered by experts like RCC Waterproofing London to restore the integrity of basement foundation walls and prevent leaks.
$50 - $300+ per linear ft.
For damp or moist basements, interior waterproofing (or internal waterproofing) is the ideal solution. It is best to address a damp basement promptly to prevent the growth of mold and mildew, which can cause unpleasant odors and health-threatening bacteria. RCC Waterproofing London can help manage hydrostatic pressure that leads to water buildup and wet basement walls with this effective service.
$50 - $100 per linear ft.
A sump pump is a crucial component for draining water that collects in a sump pit from your weeping tiles. The sump pit includes a cover to prevent debris from damaging the system. Sump pumps are often used in conjunction with interior waterproofing systems to create a comprehensive waterproofing solution. Our sump pumps can be equipped with backup batteries to ensure they remain operational during power outages.
$500 - $3000
If you're looking to create more livable space in your home, your basement is the perfect place to start. Basement lowering, also known as underpinning, is a service offered by waterproofing companies to increase the ceiling height and overall living area in your basement. Underpinning not only provides more space for your family but also significantly increases your property's value.
$300 - $500 per square ft.
Foundation cracks that are ignored will almost inevitably lead to a leaky basement. For certain situations, an epoxy crack injection can be a cost-effective and efficient solution provided by RCC Waterproofing London. This type of foundation repair uses a two-part epoxy resin to seal cracks and protect your foundation from water leaks and further damage. The epoxy is injected into the cracks through special ports, reassembling the broken concrete foundation parts.
$50 - $650
The best time to waterproof a foundation is during its construction.

$2.75 - $4 per square ft.
For homes with crawlspaces, crawlspace encapsulation is an essential waterproofing service. An improperly waterproofed crawlspace can lead to a damp basement and water leaks. RCC Waterproofing London has extensive experience in providing waterproofing solutions to address this specific issue, which is more common in older homes. We will properly encapsulate your crawl space, sealing your home from potential water-related problems.
$7 per square ft.
A structural crack in the foundation is indicated by an uneven wall or a crack that is 1/4" or wider. Repairing structural foundation cracks often requires adherence to engineering standards. Horizontal cracks are particularly dangerous as they indicate significant pressure on the basement walls from the surrounding earth. While all basement cracks are undesirable, horizontal fissures require immediate attention.
Foundation Structural Repair Water damage from burst hot water tanks, broken water lines, or other types of flooding can be severe and will worsen if not addressed immediately. Our flood restoration specialists at RCC Waterproofing Restoration London use advanced moisture meters to assess the damage and industrial-grade blowers and dehumidifiers to dry wet areas and prevent further harm.
$1000 - $100,000 per size of job
