When it comes to basement waterproofing in London, making the right decision about what to do is critical. Basements tend to take on water, and many people start to notice moist basement walls from time to time, water puddles here and there, or—worst case scenario—flooding during the rainy season, all signs that you need cellar waterproofing work at your London property.
Much of our basement waterproofing work in London is done to fix humid, damp, or downright wet basements that have led to peeling paint, mold and mildew growth, rotted wood, and damage to property in these areas. At Dry Systems Ltd, our builders are experts at waterproofing and cellar waterproofing across London. As we know from experience, when the soil outside becomes saturated, water can seep through these cracks, and even the most structurally sound basement walls can absorb water from the soil and transfer it to the basement interior, making the walls feel wet, at that point, basement waterproofing at your London home or business is crucial.
In terms of damage and progress, as the water from the walls evaporates, the air in the basement becomes more humid. A high-quality dehumidifier will help remove excess basement humidity, but the best long-term solution is to waterproof the walls.

While it is not a common issue, rising damp is about the hardest type of damp to repair and one of the reasons people contact us to do basement or cellar waterproofing at their London property. Rising damp occurs when ground moisture rises in buildings’ walls.with signs that include tide marks along the wall, crumbling floorboards, and deposits of powdery white salts on both floors and walls.
Rising damp arises at the ground floor since the rising moisture is from the ground. Condensation is mistakenly thought to be the cause of rising damp.
Moisture rises through concrete floors because of the lack of a damp proof membrane when the floor was laid. Damp easily travels through concrete because of its porosity. The problem escalates when the moisture bridges the levels of concrete and get to the top layer. Generally, it is at this stage that you notice damp carpets, cold floor coverings, and warping floors.
Environmental adjustments around your home can have a huge impact on the ground moisture levels. If for instance, you uproot a tree or large shrub from your compound, the water that this plant initially utilised accumulates in the ground.
Water levels rise and pressure is exerted on your homes instead. The concrete slabs usually take the biggest hit after the damp proof course has been bridged. All things to consider before you contact us for your basement waterproofing work in London.
DO – DETERMINE THE SOURCE
OF THE WATER
Our basement waterproofing work in London always starts with an assessment of the site and seriousness of the situation. As concrete is porous, you can often see wet streaks that let you know where the water is coming in.
Look for streaks along cracks, at the corners of windows, between mortar joints (for cement block walls), and around pipes where they enter or exit, such as a water-supply line or a sewer pipe.If entire wall surfaces are wet, however, it’s going to be necessary to do further sleuthing. The moisture might come from elsewhere, most likely from the ground which means you probably need new basement waterproofing at your London property.
DON’T – MAKE WALL REPAIRS WITH
STANDING WATER IN THE BASEMENT
During a rainy season, a crack in a basement wall can allow an inch or two of water in, but before you seek to repair the crack, it’s necessary to remove all the water from the floor. Working in a flooding basement increases the risk of electrical shock or electrocution. Our basement waterproofing specialists across London are on hand to help you dry out the space and when the basement is water-free, they will proceed with inspecting, fixing, and effectively waterproofing the basement walls.
When it comes to basement waterproofing and cellar waterproofing in London properties, considering the size of the basement is an important first step. Our basement waterproofing team in London will calculate the cost of drainage based on linear footage, something not to be confused with square footage, the formula you use to buy flooring or paint. Those decisions should wait until the basement is dry and ready for an upgrade.
If the previous homeowner did not do basement waterproofing in their London property before finishing their building, you probably have a mess to clean up, or work to be done to clear areas that may have been affected by moisture or damp damage.
As a rule, basement waterproofing in London is less expensive on homes built in the late 1960s or later, largely due to the footer components to their foundations, which allows the water tunnel to rest directly on top of the footer. The water tunnel is u-shaped. Using the existing footer as the fourth side, older homes may not have a footer in place, or they may have a very thin (less than 3 inches thick) concrete floor. These variations require a contractor to use fast track drainage.
If your foundation is made of concrete block, water can seep into the blocks and fill the hollow cavities. This buildup can decay the blocks, grow mold, and eventually seep into the interior of your basement, another important thing to establish before any cellar or basement waterproofing is done at your London property. To prevent this issue, our basement waterproofing engineers drill weep holes into the lowest block. This allows the water to drain into the installed drainage track, and keeps the wall dry and intact.
If you have significant water damage, you may need to repair that before doing basement waterproofing at your London site.
For all our basement or cellar waterproofing work in London, the first thing we do is make sure the concrete floor next to the wall is broken up and removed (a section about 6-8 inches across). If needed, weep holes are drilled.
The next stage of a basement waterproofing project in London is the drainage track being placed on the footer (or next to the wall if no footer is present). Gravel is placed around the track, which both filters the water and holds the track in place. The track drains into the sump pit for the pump to discharge.
If your walls are blocked, a dimple board is attached to the wall, to cover the weep holes. After all the components are in place and connected, new concrete is poured over the track to replace the removed floor sections. For any basement waterproofing work in London, contact Dry Systems.
