Can you waterproof a basement from the inside?

Of course! Reputable our London basement waterproofing contractors will seal the interiors of your basement walls with the most efficient masonry waterproofing products.

As soon as the paint dries, the adhesive will form a watertight bond that stops water from leaking into your house. This is how our experts make sure that your basement walls are waterproofed from the inside.

What is the best waterproofing method for a basement?

One of the most efficient basement waterproofing methods is using a basement tanking Type C solution. This means that our tanking specialists will install a Cavity Drain System that will redirect the surrounding water towards your drainage pipes or a sump pump and away from the property, keeping your basement or below ground area completely dry.

How do I stop water seepage in my basement floor?

  1. Install gutter extensions and sealers.
  2. Close the gaps.
  3. Rebuild the crown.
  4. Reconstruct the landscape.
  5. Refurbish footing drains.
  6. Place a curtain drain.
  7. Drain the water.
  8. Waterproof the basement walls.

Is it better to waterproof a basement from the inside or outside?

Our experts will need to first assess your basement before deciding whether to waterproof your basement from the inside or outside.

Type A basement tanking using a direct coating system is the form of waterproofing that our specialists use when applying a membrane to the interior or exterior walls of your below ground area. This makes the walls, ceiling, and floor of your property watertight by sealing the surfaces completely from any water or ingress.

Can water come up through a concrete basement floor?

Concrete is porous, which means water can seep through it. There is little you can do about water flowing under the ground and then pushing up against the walls and floors of your basement.

You should call our basement waterproofing specialists in London to assess the leak as we may have the materials and know-how to help.

Why is my basement floor drain backing up?

In our experience as a basement waterproofing contractor in London, there are several reasons why water might be backing up out of the floor drain. Usually, it implies that the drain under your basement’s floor is either blocked or completely filled with water.

This can be caused by a rainstorm that has overwhelmed your drainage system or even the main sewer system. Your floor drain might also be backing up because of a clog in the drainage, house trap, or in the sewers.

What is negative side waterproofing?

Negative side waterproofing is a kind of cellar plastering method, which is defined as the administration of a coating substance in the interior of a wall or foundation. Its primary function is to serve as a barrier to avoid water leakage on your basement’s walls and keep them dry at the same time.

Why is water coming up through a concrete floor?

Too much moisture in your home’s foundations can contribute to the deterioration of your concrete floor. If your foundation is lacking insulation, has cracks, or is porous, moisture can seep in, resulting in water accumulation in your basement.

How is basement waterproofing done?

Waterproofing an old basement starts with the excavation of the sides of your house’s footing. Once this is done, the basement walls are properly washed then thoroughly dried.

Waterproofing solutions are then applied to the dried up walls and drainage tiles – also known as weeping tiles – are installed on all sides of the footing.

What is blindside waterproofing?

Also known as pre-applied waterproofing, blindside waterproofing is a kind of membrane coating utilised during the installation process. It reverses the usual waterproofing application since the system is installed before the foundation is poured.

Different Kinds Of Basement Waterproofing Systems

There are various waterproofing systems you could choose from to improve your basement. These systems can be installed in different ways and at various places in your basement.

Barrier Protection

Barrier protections are continuous, impenetrable installations applied on all sides of your basement. These barriers will stop water from passing through your walls.

Structurally Integral Protection

For this approach, the basement’s structure is made from a water-resistant material, which is usually reinforced concrete or steel sheet piling.

Drained Protection

While the methods mentioned above aim to stop water from leaking into your basement, the Drained Protection technique allows water vapour into the structure but is managed by drainage that removes the excess water.

Combined Protection

In certain situations, our reputable London basement waterproofing company will suggest combining the methods mentioned above to guarantee that your basement will not let any water or damp inside.

Tanking And Making Your Cellar Dry

Cellars are often a sizable part of your home and can be used to add more space to your house by making them into a fully usable room. However, it is important to use appropriate cellar tanking methods to prevent moisture or leakage from damaging your new basement-based home extension.

Tanking a cellar can be expensive depending on the kind of basement you have and the amount of damp present around your house. According to our tanking professionals, you could expect to pay more for tanking your basement if:

  • Your house is built on solid or marshy ground
  • The water level around your home is extremely high
  • Your basement has a concrete plated floor

Waterproofing For Basement Excavation

There are a few methods on how to waterproof your basement excavation. These are:


One of the most common types of basement waterproofing is underground tanking. By applying a waterproofing membrane coating to the interior or exterior surface of your walls or bricks, our specialists ensure that your property is completely protected from the elements!

Learn about the best waterproofing methods by visiting our website and reaching out to the best basement waterproofing companies London has to offer.

Drained Cavity

Drainage cavities are made in between the internal and external basement walls and floorings in order to gather and drain water that has penetrated the walls through the use of a pump.

Points To Consider When Waterproofing Your Basement

Aside from your basement’s design, you will need to consider a few other factors when deciding to correctly waterproof your basement. What works on your neighbour’s basement might not be appropriate for yours.

London basement waterproofing experts at Environ Property Services recommend doing the following before waterproofing your basement:

  1. Have tanking experts check soil composition and the level of water via a site investigation.
  2. Assess risks to highlight high water tables and the possibilities of waterlogging in the future.
  3. Analyse floor plans of the basement to best plan where waterproofing should be established.
  4. Have a Third-Party Certification to prove that the materials are applicable for its proposed use.
  5. The designer should have relevant indemnity insurance to cover the project.
