Crystal Damp Proofing & Basements

Leading Basement Waterproofing Specialists in Islington EC1, N1.

We carried out a highly complex project in Islington; basement waterproofing using the Cavity Drain Membrane with a sump pump system. Due to a large amount of water seeping through the concrete floor, a temporary sump pump system was used.

By digging a hole in the middle of the basement and putting a pump there, we got rid of the temporary water that made our work difficult. The project was successfully completed, and the basement is now fully protected against water.

Crystal Damp Proofing & Basements is a small family-run business that specializes in basement waterproofing. We install the cavity drain membrane system together with drain channels and the sump pump. We do not like giving water any chances. We use sump pump systems with built-in alarms, two pumps, and battery backup giving you the maximum protection you need.

What materials are used in Basement, Cellar, and Vault waterproofing?

The fundamental element is to find the cause of the formation of moisture, fungus or leakage through the pipes passing through the rains. If a given room, such as a utility room and meaning is below the ground, it is worth including as low groundwater with an increased risk of water occurrence in the Basement.
The best material for Waterproofing is the Cavity drain membrane because it drains water automatically through the installed Sump Pump System.
The underground Vault, located mainly under the sidewalk along the road, is very prone to leakage due to cracks that are caused by vibrations from passing vehicles.
It is a very unpleasant sight as water drips from the ceiling onto personal belongings that we have stored for years. The frequently used Tanking Slurry is poorly made in combination with waterproof render; it cannot provide good deodorization against water drips or wet spots. If a Cavity Drain membrane is used, the drainage from the groundwater is more effective and ensures dryness in the room.

Can basement waterproofing be used in old Victorian houses?

Yes, we can use it significantly because the bricks in most cellars are so damaged that the water penetrates the pores previously damaged in the bricks (i.e. washed out). Since Victorian houses are close together, there is also a risk of moisture penetrating or rising upwards.
So at this stage, it is worth considering Basement waterproofing in Victorian houses.

What is the cause of wet floors and walls in our Basement during the rainy season?

The rainy season is not friendly for our houses, including foundations and basements. Our cellars should be protected both internally and externally against groundwater. In the case of old houses, protection against moisture or groundwater certainly no longer works due to age, or no protection against humidity has been made.

Is a Sump pump system required for Cavity wall membrane installation?

Yes, of course, because this system’s functionality consists of closing the drained water in the membrane system placed on the walls and the floor. The system is mounted under the floor membrane, which is connected to the pump system, ejecting the collected water into drainage pipes with a larger volume to improve the drainage water permeability.
The system, as mentioned earlier, means that we can keep the Basement dry, live in it and feel safe that nothing will fall on our head, i.e. (a drop of water).

What kind of ventilation to use after completing the Cavity Membrane System.

In the Basement, Ventilation is rare, especially in the Cellar, because it has to be cool to keep the temperature low.
These causes mould, fungus and high condensation.
Usually, a recuperative ventilator is recommended to get fresh air from the outside and expel harmful air from the inside.

  • Suitability of the chosen method for the structure

Which Basement Waterproofing Method Is Right For You?:

Type A – Barrier System (Tanking)  
One of the most common methods of basement waterproofing is underground tanking. By applying a waterproofing membrane coating to the interior or exterior surface of your walls or bricks, our Crystal Damp Proofing & Basements experts ensure that your Islington property is completely protected from the elements.

Type B – Waterproofing
Type B waterproofing is an inbuilt characteristic of the actual structure by adding waterproofing additives to the concrete used to form the floors and walls of the structure. Although normally effective in its own right, the joints of the structure are it’s weak spot and as such are susceptible to water penetration. Type B waterproofing is normally backed up by combining type A, C or sometimes both to ensure a watertight system and minimise risk. Type B basement waterproofing is normally specified in newbuild below ground structures.

Type C – 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.
